involve questions  of evidentiary sufficiency, see,  e.g., United

     1The applicable statutes provide in pertinent part:

facts in the light most congenial to the government.

          Appellant and Arnett Lynch,  an inveterate bank robber,

often used drugs at a hangout in Boston, known euphemistically as

"the Spot."   On several occasions appellant, emphasizing that he

"wanted  to learn the ropes," expressed the hope that Lynch would

provide tutelage in how to rob banks.  

          The  problem with  wishes is  that they  sometimes come

true.    Cf. Aesop,  The  Old  Man  and  Death (circa  550  B.C.)
                                                        

(predicting  that "[w]e would often  be sorry if  our wishes were

gratified").    On  January  29,  1992,  appellant  restated  his

aspirations and  mentioned  the availability  of  transportation,

telling  Lynch that his friend, Lucille  Aulmond, had agreed (for

ten dollars) to drive him to the downtown area.  Lynch and Taylor

entered  Aulmond's  automobile.    During the  trip,  Lynch  told

appellant that they were  going to "do bizank" [a  slang term for

"bank," according to Lynch's trial testimony]  and "rob the 2T's"

[a reference to two tellers].

          After  dropping  off  a  friend,  Aulmond,  on  Lynch's

instructions,  drove  to  downtown  Boston and  parked  near  the

intersection of Clarendon St. and Newbury St. Lynch walked to the

corner to check a branch office of Bank of Boston, but found that

it had closed for the day.2  When Lynch returned  to the vicinity

of the parked car, appellant joined him on the sidewalk.  The two

men then entered a  nearby branch of United States  Trust Company
                    
                              

     2That  bank had been robbed several  days earlier by Lynch's
compatriot, William  Corgain, who  told Lynch that  the bank  was
easy pickings because only two tellers were on duty.

                                3


(UST).

          Appellant remained hard by  the entrance, watching both

the bank's interior and  the street.  Meanwhile, Lynch  strode to

the center of the  lobby.  The manager, Elizabeth  Nentwig, asked

Lynch if he needed  assistance.  Lynch proved capable  of helping

himself; he  drew a gun  and advised Nentwig  that a  robbery had

begun.  Lynch then  grabbed a customer's briefcase,  approached a

teller (Helen Huppoch),  and demanded money.  He  received $2,748

from  Huppoch and  inserted  it into  the  briefcase.   Appellant

yelled,  "come on,  let's  go,"  and  the  two  men  sprinted  to

Aulmond's car.

          Once  inside the  automobile,  Aulmond asked  what  had

happened, and appellant responded:  "I hit  a guy in the face.  I

punched a  guy in the face."   Lynch screamed at  Aulmond to stop

talking and start driving.   She complied.  After  Aulmond made a

wrong  turn, the men grew impatient, bolted from her vehicle, and

completed their  escape in a  taxi.  They then  split the spoils,

but, there being scant honor among thieves, four men later mugged

Lynch and stole his share of the proceeds.

          The  next  day,   a  man  subsequently   identified  by

percipient witnesses  as Taylor entered a  BayBank branch located

at 285 Huntington Ave. in Boston.   The man approached a teller's

station, shoved aside a customer, Alaina Gurski, and, threatening

to  shoot Gurski, demanded that the teller, Raya Aruin, hand over

her  money.   The man held  an object  that both  Aruin and Ellen

Clavin,  a customer  service representative  working at  a nearby

                                4


teller  station, described at  trial as a  gun.  The  robber fled

after receiving $2,458 from Aruin.

          In due season, a  federal grand jury indicted appellant

for  his role in the  two robberies.   The superseding indictment

contained  three counts:  count  1 charged Taylor  and Lynch with

committing  the   UST  robbery;  count  2   charged  Taylor  with

committing the BayBank robbery;  and count 3 charged  Taylor with

carrying a firearm during and in relation to the BayBank robbery.

Lynch entered into a plea agreement and Taylor stood trial alone.

The  jury  found  him guilty  on  all  three  counts.   Following

imposition of sentence, Taylor filed this timely appeal.

          Taylor's brief  contains seven distinct  assignments of

error.   Six of these asseverations   relating, vacuously, to the

joinder  of  counts  arising  from two  separate  robberies,  the

sufficiency of the evidence,  and the jury instructions    do not

necessitate exegetic treatment.   We dispose of these  six claims

in a decurtate fashion (see  infra Parts III - V).   We then turn
                                            

to  appellant's  most  vexing  point:   his  complaint  that  the

prosecutor's  closing argument contained improper and prejudicial

misstatements,  including impermissible comments  on his election

not to testify.  See infra Part VI.
                                    

II.  THE RAISE-OR-WAIVE RULE
          II.  THE RAISE-OR-WAIVE RULE

          Because many of the  assigned errors were not preserved

for  appeal by timely objections,  we pause first  to discuss the

raise-or-waive  rule.    In general,  the  law  ministers to  the

vigilant,  not  to  those  who  sleep  upon  perceptible  rights.

                                5


Consequently, a  litigant who deems himself aggrieved  by what he

considers to be an  improper occurrence in the course of trial or

an erroneous  ruling by the  trial judge  ordinarily must  object

then and there, or forfeit any right to complain at a later time.

The policy reasons behind the raise-or-waive rule are rock solid:

calling a looming error to the trial court's attention affords an

opportunity  to  correct  the  problem  before  irreparable  harm

occurs.  Then, too, the raise-or-waive rule prevents sandbagging;

for  instance,  it  precludes  a party  from  making  a  tactical

decision to refrain from  objecting, and subsequently, should the

case  turn sour,  assigning error  (or, even  worse, planting  an

error and nurturing the seed as insurance against an infelicitous

result).     So  viewed,  the  requirement   that  parties  raise

contemporaneous  objections to improper  questions, comments, and

the like serves an  important purpose in promoting "the  balanced

and orderly  functioning of  our adversarial system  of justice."

(1995).

          Despite its  strength and salience,  the raise-or-waive

rule is not absolute.  But, rescue missions are restricted to the

correction of "plain" errors.  See United States v. Olano, 113 S.

268, 273 (1st Cir. 1987); Griffin, 818 F.2d at 100; see generally
                                                                           

Fed. R. Crim. P. 52(b).

                                6


          The    plain    error    doctrine    concentrates    on

"blockbusters," to the exclusion of "the ordinary backfires . . .

which may mar a trial record."  Griffin, 818 F.2d at  100.  Under
                                                 

it,  appellate courts will notice  unpreserved errors only in the

most  egregious circumstances.    At a  bare minimum,  therefore,

bevues not seasonably brought to the attention of the trial court

must,  in order  to  command  appellate  intervention,  "affect[]

substantial rights."  Fed. R. Crim. P. 52(b).

          An unpreserved  error is deemed plain  (and, therefore,

to affect  substantial rights) only if the  reviewing court finds

that it skewed the fundamental fairness or basic integrity of the

proceeding below in some major respect.  See Griffin, 818 F.2d at
                                                              

100.  As the  Supreme Court itself has  written, the plain  error

doctrine  applies  in  those   circumstances  in  which,   absent

appellate intervention, "a miscarriage of justice would otherwise

result."  United States v. Frady,  456 U.S. 152, 163 n.14 (1982).
                                          

Given   these  parameters,   it  is   not  surprising   that  the

jurisprudence  of plain error  invests substantial  discretion in

the  court of appeals.  See Olano,  113 S. Ct. at 1776 (observing
                                           

that "the decision to correct  the forfeited error [rests] within

the  sound discretion of the Court of Appeals"); United States v.
                                                                        

Whiting,  28 F.3d 1296, 1308 (1st Cir.) (same), cert. denied, 115
                                                                      

S. Ct.  378 (1994).   Even when  faced with  an apparently  plain

error, an appellate court "has authority to order correction, but

is not required to do  so."  Olano, 113 S. Ct. at 1778.   For the
                                            

most  part, this  discretion should  be exercised  sparingly, and

                                7


should  be reserved for the  correction of those  few errors that

"`seriously affect  the fairness, integrity or  public reputation

of  the judicial proceedings.'"  United States v. Young, 470 U.S.
                                                                 

1,  15 (1985) (quoting United  States v. Atkinson,  297 U.S. 157,
                                                           

160 (1936)).

III.  JOINDER AND SEVERANCE
          III.  JOINDER AND SEVERANCE

          Appellant  excoriates the  government  for  bringing  a

single indictment that joined a count relating to the UST robbery

with two  counts relating to the BayBank  robbery.3  In a similar

vein,  he calumnizes the district court for refusing to sever the

ostensibly incompatible counts.  The chastisement is unwarranted.

          Although appellant  now maintains that  the counts were

improperly joined, he raises this objection for the first time on

appeal.  Thus, we afford  plain error review.  See United  States
                                                                           

v. Stackpole, 811 F.2d 689, 693 (1st Cir. 1987).
                      

          Separate offenses may be  joined in the same indictment

if the charges are "of the same or similar character or are based

on  the  same act  or  transaction  or on  two  or  more acts  or

transactions connected together or constituting parts of a common

scheme or  plan."  Fed. R. Crim. P. 8(a).  In determining whether

counts  are properly  combined  for trial,  we historically  have

considered  whether the charges are  laid under the same statute,

whether  they involve similar  victims, locations,  or   modes of
                    
                              

     3Appellant does  not argue  that linking the  firearms count
with the robbery counts formed a basis for a claim of misjoinder.
Accordingly, we deem any such argument waived.  At any  rate, the
firearms  charge was  inextricably  intertwined with  the  second
robbery, and could hardly be separated from it.

                                8


operation,  and the  time  frame  in  which the  charged  conduct

occurred.  See, e.g., United States v. Chambers, 964 F.2d 1250-51
                                                         

(1st Cir. 1992); United States v.  Gray, 958 F.2d 9, 14 (1st Cir.
                                                 

1992).  Under the present circumstances, joining the three counts

lodged against appellant does not constitute plain error.

          The  two robberies  involved the  same type  of victims

(federally  insured  banks).   They were  charged under  the same

statute  (18  U.S.C.    2113),  took  place  in  the same  locale

(downtown  Boston),   and  occurred   in  the  same   time  frame

(successive days).   Such similarities have  routinely been found

to justify joinder.   See,  e.g., Chambers, 964  F.2d at  1250-51
                                                    

(finding  joinder proper  when  robberies all  involved federally

insured  banks in the greater  Boston area and  occurred within a

ten-week period); Gray, 958 F.2d  at 14 (similar).   Furthermore,
                                

the evidence here suggests that the first robbery was, in effect,

a training mission for the second.  Therefore, we do not think it

would  be plain  error to  conclude that  the two  robberies were

parts of  "a common scheme or plan" as  that term is used in Rule

8(a).

          Appellant's contention that the district court erred in

refusing to sever the  robbery counts, while arguably preserved,4

also  lacks force.   Though  the Criminal  Rules  empower federal

                    
                              

     4It is unclear whether appellant's severance motion   which,
in terms,  did not request  that the  two bank robbery  counts be
tried  separately    properly preserved  the severance  issue for
review.   Because  severance was  not required  in any  event, we
assume for argument's sake that the issue was sufficiently raised
in the court below.

                                9


courts to  grant relief  from  prejudicial joinder  of counts  in

criminal  cases, see Fed. R. Crim. P. 14, severance decisions are
                              

ordinarily won or lost in the  trial court.  We will overturn the

denial of  a motion  for severance  only  for a  patent abuse  of

discretion.  See  United States v. Pierro, 32 F.3d  611, 616 (1st

U.S. 1079 (1992).   This discretion applies to refusals  to sever

counts as well as to refusals to separate defendants for purposes

of trial.  See, e.g., Chambers,  964 F.2d at 1251.   Establishing
                                        

an abuse of discretion usually entails a showing that improper or

prejudicial  joinder likely  "deprived  the defendant  of a  fair

trial."  United States v. Nason, 9 F.3d 155, 158 (1st Cir. 1993),
                                         

cert. denied, 114 S. Ct. 1331 (1994).
                      

          Appellant faces  a high  hurdle, given  Chambers, Gray,
                                                                          

and other cases in which we have upheld the trial court's refusal

to sever counts involving multiple bank robberies.  He strives to

distinguish these  cases on  the ground  that they  involved more

than two  robberies, and, thus, yielded telltale  patterns.  This

argument fails  for two reasons.   First, common  sense indicates

that  the greater the number of robberies, the greater the danger

of prejudice that joinder poses.  Second, there is no shortage of

sound precedent upholding the joint trial of two   and only two  

robbery  counts in a single indictment.  See, e.g., United States
                                                                           

v.  L'Allier, 838 F.2d 234, 240-41 (7th Cir. 1988); United States
                                                                           

v. Shearer, 606 F.2d 819, 820 (8th Cir. 1979).
                    

                                10


          Apart  from  this  curious   slant  on  the  number  of

incidents,  appellant  offers  no   basis  for  suspecting  undue

prejudice.  His bare allegation that, if the jury were to believe

that  he was  involved in  one bank robbery,  then it  might also

(improperly) be led  to believe from that fact alone  that he was

involved  in the  other,  is simply  not  enough.   This type  of

spillover  is standard  fare whenever  counts  involving discrete

incidents  are linked in a single indictment.  We have repeatedly

held that such  a garden  variety side effect,  without more,  is

insufficient to require severance.  See United States v.  Boylan,
                                                                          

898 F.2d  230, 246 (1st  Cir.) (collecting cases),  cert. denied,
                                                                          

498  U.S.  849  (1990).   Moreover,  the  case  for prejudice  is

especially  weak in  this instance  because the  district court's

jury instructions delineated the separateness of the three counts

and made  it clear that the  jury had to consider  each charge on

its own merits.5

          In sum,  we find no  plain error in the  joinder of the

three  counts contained  in  the superseding  indictment, and  no

misuse  of discretion  in  the  district  court's eschewal  of  a

severance.

IV.  SUFFICIENCY OF THE EVIDENCE
          IV.  SUFFICIENCY OF THE EVIDENCE

          Appellant challenges the sufficiency of the evidence in

three respects.   He says that the proof did not show (1) that he

                    
                              

     5We also note that,  even if the robberies had  been charged
in separate indictments, the UST robbery would in all probability
have  been admissible  to prove  preparation, plan,  or knowledge
regarding the BayBank heist.  See Fed. R. Evid. 404(b).
                                           

                                11


participated  in the  UST  robbery,  (2)  that he  committed  the

BayBank robbery, and/or  (3) that the perpetrator  of the BayBank

robbery  carried a real gun.   In assessing  these challenges, we

scrutinize the  evidence in  the light  most compatible with  the

verdict, resolve all credibility disputes in the verdict's favor,

and then reach  a judgment  about whether a  rational jury  could

find guilt beyond a reasonable doubt.  See Echeverri, 982 F.2d at
                                                              

677; Maraj, 947 F.2d at 522-23; Boylan, 898 F.2d at 243.
                                                

          On the  sufficiency issues, a further  obstacle impedes

appellant's progress.  Where,  as here, challenges to evidentiary

sufficiency are unpreserved   the defendant moved for judgment of

acquittal at the end  of the prosecution's case, but  then failed

to renew the motion after presenting evidence on his own behalf  

a special variant of  the raise-or-waive rule applies.6   In such

straitened circumstances, an appellate court should stay its hand

unless intervention is  necessary to  prevent a  clear and  gross

injustice.   See United States  v. McDowell, 918  F.2d 1004, 1010

          Appellant's first  two  sufficiency challenges  can  be
                    
                              

     6Of  course,  if a  defendant  files  a timely  post-verdict
motion   under  Fed.  R.  Crim.  P.  29(c),  he  may  escape  the
consequences  of  his earlier  procedural  default.   See  United
                                                                           
States v.  Castro-Lara, 970 F.2d  976, 980 (1st  Cir. 1992).   In
                                
this case, appellant proffered no such motion.

                                12


dispatched with  alacrity.   The government  prosecuted appellant

for  the UST  robbery on  the theory  that he  aided  and abetted

Lynch's felonious conduct.  See 18  U.S.C.   2 (1988).7  The jury
                                         

convicted him on this basis.  Its finding is amply supported.

          Criminal intent  is an important element  of aiding and

abetting, see  United States v.  Tarr, 589 F.2d 55,  59 (1st Cir.
                                               

1978), and the supposed lack of any such intent lies at the heart

of  appellant's  challenge.   Proof  of  this  element demands  a

showing  that the  defendant consciously  shared the  principal's

knowledge of the  underlying criminal act,  and intended to  help

the principal.   See United States v.  Albert, 773 F.2d 386,  390
                                                       

(1st Cir. 1985).   We hasten to  add, however, that this  showing

may be made wholly on the basis of circumstantial evidence.

          We believe  that  the jury  could have  reached such  a

conclusion  here.    Viewed  favorably  to  the  government,  the

evidence suggests that appellant  sought Lynch's help in learning

to  rob banks, furnished transportation so that the two men could

rob  a bank, discussed the  prospect en route,  stood watch while

Lynch  held up the teller, facilitated a joint escape, and shared

fifty-fifty  in  the  purloined   fruits.    These  facts  firmly

underbrace the  jury's finding  that appellant aided  and abetted

Lynch in the commission of the robbery.

          Appellant's   challenge  to  the   sufficiency  of  the

                    
                              

     7The  statute provides  that:   "Whoever commits  an offense
against  the United  States or  aids, abets,  counsels, commands,
induces  or   procures  its   commission,  is  punishable   as  a
principal."  18 U.S.C.   2 (1988).

                                13


evidence  that he committed the  BayBank robbery is  jejune.  Two

eyewitnesses, Aruin and  Clavin, identified him in  open court as

the   perpetrator.      Although   appellant   denigrates   their

reliability,  the  jury  was   plainly  entitled  to  accept  the

identification and to find that appellant committed the crime.

                     B.  The Firearms Count.
                               B.  The Firearms Count.
                                                     

          Appellant fares equally poorly  in his final  challenge

to evidentiary sufficiency.  The statute of conviction, 18 U.S.C.

   924(c), requires  proof  beyond a  reasonable  doubt that  the

person  perpetrating the predicate offense used a real gun.  See,
                                                                          

e.g., United States v. Kirvan, 997 F.2d 963, 966 (1st Cir. 1993).
                                       

Appellant  tells us  that  the government  failed  to prove  this

essential fact.  We do not agree.

          This  court  recognized in  Kirvan  that,  in order  to
                                                      

convict  under section 924(c), the gun must be real, but it "need

not be proven to be loaded  or operable . . .  ."  Id.  While  "a
                                                                

toy  or a  replica will  not do,"  the prosecution  satisfies its

burden  simply  by  showing  that   the  gun  is  a  gun.     Id.
                                                                           

Furthermore, the government's proof on this point need not  reach

a  level of scientific certainty.   On the  contrary, lay opinion

testimony may be employed to propel  a finding that an object  is

in fact a  real gun.8   See, e.g., Parker  v. United States,  801
                                                                     
                    
                              

     8Kirvan  illustrates   the  point.    There,   we  found  it
                      
sufficient to justify a  conviction that two witnesses identified
the object  as a gun, and that it  made a loud noise when dropped
(consistent with it being very  heavy).  See Kirvan, 997 F.2d  at
                                                             
966-67.

                                14


F.2d 1382, 1385  (D.C. Cir.  1986), cert. denied,  479 U.S.  1070
                                                          

(1987);  United  States v.  Jones, 907  F.2d  456, 460  (4th Cir.
                                           

1990), cert. denied, 498 U.S. 1029 (1991). 
                             

          Silhouetted   against    this   backdrop,   appellant's

assignment   of  error   pales   into  insignificance.      Three

eyewitnesses to  the BayBank robbery,  each of whom  observed the

object gripped by appellant at close range, testified that it was

a gun.  This evidence is enough to allow  a rational jury to find

that  appellant carried  a  real gun.   Accordingly,  appellant's

conviction under section 924(c) worked no injustice, let alone  a

clear and gross injustice.

V.  THE JURY INSTRUCTIONS
          V.  THE JURY INSTRUCTIONS

          When reviewing a  district court's instructions  to the

jury,  we  look  at  the  charge  as  a whole,  not  in  isolated

fragments.  See Boylan,  898 F.2d at 244; Mejia-Lozano,  829 F.2d
                                                                

at  272.  If no timely objection  has been advanced at trial, see
                                                                           

Fed. R.  Crim. P. 30  (specifying when and how  objections to the

charge must be  taken), even an improper  instruction rarely will

justify  the reversal of a criminal conviction.  See Henderson v.
                                                                        

Kibbe, 431 U.S.  145, 154  (1977); United States  v. Weston,  960
                                                                     

F.2d 212, 216 (1st Cir. 1992).  So it is here. 

          In this instance, the district court warned the jury to

take  a long, hard look at accomplice testimony.9  In appellant's
                    
                              

     9To be exact, the court told the jury that the  testimony of
an accomplice was "to be scrutinized with particular care because
there is an interest that the person had in saying something that

                                15


current view,  the instruction  should have been  more elaborate;

the  court  should have  described  the  nature of  the  witness'

interest in assuaging the government, told the jurors  that their

perscrutation of such  testimony must be more searching than that

afforded to other testimony, and reminded them in the same breath

that the government had  to prove its points beyond  a reasonable

doubt.  Putting aside  the obvious question of  whether appellant

would  have been entitled to such instructions if duly requested,

the claimed  deficiencies are  precisely the type  of fine-tuning

that is consigned to the scrap heap if not called to the district

court's  attention in a timeous manner.  No matter how critically

these alleged  shortcomings in the court's  charge are evaluated,

they cannot conceivably sink to the level of plain error. 

          The  raise-or-waive  rule   also  hobbles   appellant's

remaining complaint  about the  jury instructions.   After noting

that   the   evidence   anent   eyewitness   identification   was

"straightforward," the judge told the jury:

          There are  some  four billion  people in  the
          world and in the natural course of things one
          would  expect some  of  them may  look alike.
          But, on the other hand, an experience such as
          these witnesses had, may, indeed,  make their
          observation so intense that it is reliable in
          establishing  identity  beyond  a  reasonable
          doubt.

Although  appellant   could  be  correct  in   arguing  that,  in

actuality,   an  intensely  stressful  situation  is  often  less

accurately  remembered than is a more tranquil one, he makes this

                    
                              

would be looked on with favor by the government."

                                16


point at  the wrong  time  and to  the wrong  court.   While  the

challenged instruction may not be a textbook model, we discern no

plain error in it.

VI.  THE SUMMATION
          VI.  THE SUMMATION

          Having wended  our way across  flat, easily  negotiated

territory,  we now  reach  more  problematic  turf.    Here,  the

topography features a tripartite claim of  error addressed to the

government's summation.

          We  start  with  certain   fundamental  verities.    "A

prosecutor is permitted vigorous advocacy, so long as he does not

stray into forbidden terrain."   Palmariello v. Superintendent of
                                                                           

M.C.I.-Norfolk,  873 F.2d 491, 494 (1st  Cir.), cert. denied, 493
                                                                      

U.S.  865 (1989).  Thus, prosecutors need not pull their punches;

they may   indeed, they should   present  their cases to criminal

juries zealously.  Forcefulness  in the pursuit of justice  is to

be admired rather than  condemned.  Yet, while a  prosecutor "may

strike hard  blows, he is  not at liberty  to strike  foul ones."

Berger v. United  States, 295 U.S. 78, 88 (1935).   This maxim is
                                  

particularly relevant  to closing arguments,  for such  arguments

come at an  especially delicate  point in the  trial process  and

represent the parties' last, best chance to marshal  the evidence

and persuade the jurors of its import.   See, e.g., United States
                                                                           

v. Manning, 23 F.3d 570, 575 (1st Cir. 1994).
                    

          Of course, a prosecutor's obligation to stay within the

pale does not exist in a vacuum.  A defendant has a corresponding

obligation  to  protect his  own  interests.    When a  defendant

                                17


defaults on this obligation by failing to make a  contemporaneous

objection to  questionable comments in the  prosecution's closing

argument, the raise-or-waive  rule applies.  Afterthought  claims

of improprieties  allegedly  occurring during  the summation  are

reviewed  under  the  notably  ungenerous  plain  error standard.

Consequently,  reversal  is justified  only  if the  illegitimate

portion  of the closing argument  "so poisoned the  well that the

trial's  outcome was likely affected."  Mejia-Lozano, 829 F.2d at
                                                              

274.

          In determining whether a prosecutor's  miscues in final

argument  require reversal  under this  hard-to-satisfy standard,

this  court considers  all  the attendant  circumstances,  paying

special  heed to  factors such  as (1)  the extent  to  which the

prosecutor's  conduct  is  recurrent and/or  deliberate;  (2) the

extent to which the trial judge's instructions insulated the jury

against, or  palliated, the possibility of  unfair prejudice; and

(3)  the  overall  strength   of  the  prosecution's  case,  with

particular regard to the likelihood that any prejudice might have

affected the jury's judgment.  See id.; see also United States v.
                                                                        

Giry, 818 F.2d  120, 133 (1st  Cir.), cert. denied, 484  U.S. 855
                                                            

(1987).    Using  these  criteria,  we  conclude  that   none  of

appellant's claimed errors requires reversal.

                            A.  Matters Dehors the Record.
                                                         

          Appellant  maintains that,  during  the summation,  the

prosecutor referred  to matters  not in evidence.   Specifically,

the  prosecutor gave a  less than completely  accurate account of

                                18


the prefatory conversation between appellant and Lynch on January

29.    Appellant  greeted  Lynch,  so  the  prosecutor  said,  by

imploring:  "Maestro,  show me  how it's done."   The  prosecutor

added:   "We  know that  Maestro is Mr.  Lynch's nickname.   Why?

Because he plays  the organ in his father's church."   Warming to

this theme, the  prosecutor reiterated  the point.   He told  the

jury that, as the two  men walked into the UST  branch, appellant

again said:  "Maestro . . . show me the ropes."

          There was, in fact, no evidence of Lynch's nickname and

no evidence that appellant made a  request to be shown the  ropes

as   the  robbers  entered  the  bank.    Withal,  there  was  no
                                               

contemporaneous  objection, and  these  canards scarcely  justify

reversal under  the  plain  error doctrine.    Given  that  Lynch

admitted  to  his vocation  as a  bank  robber, his  nickname was

wholly  irrelevant to the case.  Moreover, the prosecutor gave an

innocent explanation  of the  moniker and appellant's  own lawyer
                  

twice referred to Lynch in front of the jury as "Maestro."  As to

the second  misstatement, there was evidence  that appellant made

the request  ("show me the ropes")  previously on the day  of the

robbery and on  at least one  earlier occasion.  In  other words,

the substance  of the  prosecutor's statement was  true (although

the timing was awry).

          On whole-record  review,  we conclude  without  serious

question  that the  allusions to  matters dehors the  record were

benign.  Reversal is totally unwarranted.

                  B.  The Prosecutor's Rebuttal.
                            B.  The Prosecutor's Rebuttal.
                                                         

                                19


          Next,  appellant  assails  the  prosecutor's  rebuttal,

which,  he  says,  contained  a minimum  of  three  peccadilloes,

namely, (1)  an implication that  appellant had alerted  the four

people who mugged  Lynch and  stole his booty,  (2) a  suggestion

that  Lynch should be  believed because he  suffered from sickle-

cell  anemia  and  had  tested  positive  for  HIV,  and  (3)  an

intimation that  Clavin, during her testimony,  lowered her voice

"out of fear."

          These  accusations  do  not withstand  scrutiny.    The

prosecutor made the first of the cited comments without objection

and in direct  response to defense counsel's  argument that Lynch

had turned against Taylor because the latter did not come to  his

aid  during  the mugging.    We  have  previously  expressed  our

reluctance  to find plain  error when a  prosecutor's remarks are

made  to rebut  specific statements  by defense counsel,  and are

proportionate to that end.  See  Whiting, 28 F.3d at 1302; Mejia-
                                                                           

Lozano,  829 F.2d  at  274.   Here,  our reluctance  ripens  into
                

outright  unwillingness.    Similarly, the  prosecutor's  remarks

about Lynch's  health drew  no contemporaneous objection.   Those

remarks  were obviously  designed to  rebut the  defense argument

that  Lynch was hoping to  earn a reduced  sentence by testifying

against  Taylor.  The statement  recounted facts in evidence, and

did not constitute either  vouching or an improper appeal  to the

jury's sympathies.   Finally, the remark  about Clavin's demeanor

was not out of line.  The  jury saw and heard her testimony,  and

                                20


could  determine  for itself  her state  of  mind.10   See, e.g.,
                                                                          

United  States  v.  Mount, 896  F.2d  612,  625  (1st Cir.  1990)
                                   

("Although  it is  the jury's  job to  draw inferences,  there is

nothing improper in the Government's suggesting  which inferences

should be drawn.").

                  C.  The Fifth Amendment Issue.
                            C.  The Fifth Amendment Issue.
                                                         

          The capstone of appellant's asseverational array is his

anguished assertion  that  the prosecutor's  summation  contained

comments on appellant's election not to testify, in derogation of

rights  secured to appellant under the Fifth Amendment.  We quote

the disputed portion of the prosecutor's summation:

               Is  there any  evidence that  Mr. Taylor
          said, "Oh, my God, I've been misled.  This is
          not going to  be money from his father.  I've
          got to get out of here.   I've got to warn my
          friend, Lucille Aulmond.   She gave me  rides
          in   the  past,   but   this   is   something
          different."   He  stayed true  in his  anchor
          position.
               Mr.  Lynch  went   up  to  the   window,
          demanded money.   He was very  unafraid.  Mr.
          Lynch demanded money  that wasn't  his.   Did
          Mr. Taylor  say:   Oh, my  God, I'm going  to
          leave this place and warn my  friend, Lucille
          Aulmond?  No.  He stayed true  to that anchor
          position.  And, in fact, he yelled, "Come on,
          let's go."  
               Lynch  points to  the door.   Mr. Taylor
          waits  there and  does  he say:   Look,  just
          because I'm here, I'm sorry what happened.  I
          didn't  know  it was  going  to  happen.   Is
          everybody  all   right?    I  know   who  was
          responsible.
                    
                              

     10While defense counsel did not  interject a contemporaneous
objection  during the  prosecutor's rebuttal,  he did  bring this
remark  to   the  court's  attention  at   a  sidebar  conference
immediately  following  the summations.    The  judge refused  to
resurrect the matter,  stating:  "I will  leave it.  It  is up to
the jury to make that determination."  We agree.

                                21


               He left with the  money. . . .   When he
          got  back  to  the  car,  you  heard  Lucille
          Aulmond, and she said, "What happened?"  Does
          he say:  Lucille, he robbed  a bank; I didn't
          know  it was going to happen;  I'm sorry.  "I
          hit  a man  in the  face"  was what  you got,
          instead.  Not the truth, just another part of
          the lie . . . .
               And  they drive  two  blocks away.   Mr.
          Lynch  gets out  of the  car.   Does Terrence
          Taylor stay with  his friend?   "Lucille, I'm
          involved in this.   You  shouldn't have  been
          involved.   I  didn't  even  know  about  it.
          Let's go  to the police and  clear this whole
          thing  up."  He went with the money.  Her job
          was done.
               He  took the money. .  . .   Did he take
          his share  of the money and  say, "Look, this
          is not  my money;  there it is,  police, look
          for  bait bills;  I'm turning  back  money; I
          have nothing to do with this."

          It is  a bedrock principle  that a  prosecutor may  not

comment  on a defendant's exercise of the right to remain silent.

See United States v. Robinson, 485 U.S. 25, 30 (1988); Griffin v.

(1994).  Even an indirect or inferential comment on a defendant's

silence can  transgress the Fifth  Amendment.  See,  e.g., United

v. Lavoie,  721 F.2d 407, 408 (1st  Cir. 1983), cert. denied, 465
                                                                      

U.S. 1069 (1984).

          Because  "[t]here   is  no  bright  line   marking  the

precipice between  a legitimate  assessment of  defense witnesses

and an impermissible  encroachment upon  the accused's  silence,"

Sepulveda, 15 F.3d at  1186, prosecutors must tread  carefully on
                   

this terrain.  A  prosecutor who "attempts to define  exactly the

                                22


edge  of  the precipice  approaches  at his  peril."   Rodriguez-
                                                                           

Sandoval v. United States, 409 F.2d 529, 531 (1st Cir. 1969).  In
                                   

evaluating whether a  prosecutor has  gone too far,  we must  ask

whether, in  the particular  circumstances of  a given case,  the

language  used by the prosecutor appears to have been designed to

yield  the improper inference, or, if not so designed, whether it

was  such that jurors would probably interpret it as a commentary

on the accused's  failure to take the witness stand.   See United
                                                                           

States  v. Glantz,  810  F.2d 316,  322  (1st Cir.  1987),  cert.
                                                                           

denied,  482 U.S. 929 (1987); United States v. Monaghan, 741 F.2d
                                                                 

1434, 1437 (D.C. Cir. 1984), cert. denied, 470 U.S. 1085 (1985).
                                                   

          Notwithstanding these constraints,  no Fifth  Amendment

violation inheres in comments on a defendant's decision to remain

silent in a context outside  the legal process.  For example,  in

Lema  v. United  States, 987  F.2d 48 (1st  Cir. 1993),  we found
                                 

nothing amiss  in a  prosecutor's observation that  the defendant

remained  silent during two  drug transactions.   The comment did

not  transgress  the  Fifth  Amendment  because  it  referred  to

defendant's  silence at  the scene  of the  crime rather  than at

trial.  See id. at 56; see also United States v. Ortiz,  966 F.2d
                                                                

707,  714  (1st  Cir.  1992)  (holding  that  defendant's  silent

presence   at  site   of  drug   transaction  "patently   implied

participation"), cert. denied, 113 S. Ct. 1005 (1993).
                                       

          In  this  case,   the  government   insists  that   the

challenged  statements  referred to  appellant's  silence before,

during, and after the  UST robbery, not to his  silence at trial.

                                23


When a  prosecutor's comments, fairly viewed,  are susceptible to

two plausible meanings,  one of which is  unexceptionable and one

of  which  is forbidden,  context frequently  determines meaning.

See  Sepulveda, 15 F.3d at 1187; United States v. Lilly, 983 F.2d
                                                                 

300,  307 (1st  Cir. 1992).   Where  feasible, a  reviewing court

should construe ambiguity in favor of a proper meaning:

          [A]  court should  not lightly  infer  that a
          prosecutor  intends  an  ambiguous remark  to
          have  its most  damaging  meaning  or that  a
          jury, sitting through a  lengthy exhortation,
          will draw  that meaning from the  plethora of
          less damaging interpretations.

Donnelly  v.  DeChristoforo, 416  U.S.  637,  647 (1974);  accord
                                                                           

Lilly, 983 F.2d at 307.  This rule of construction has heightened
               

desirability in  the absence of a  contemporaneous objection for,

when the target of the comments does not interrupt and register a

timely objection,  it seems  especially appropriate to  "give the

arguer  the  benefit of  every  plausible  interpretation of  her

words."  Sepulveda, 15 F.3d at 1187.  We are especially reluctant
                            

to "fish in the pool of ambiguity" when, as now, the  complaining

party failed  to  bring a  dubious comment,  easily corrected  on

proper  notice, to  the immediate  attention of the  trial court.

Id. at 1188.
             

          Evaluated against  this  benchmark, we  do not  believe

that the quoted remarks trespassed on appellant's Fifth Amendment

rights.   While a suspicious mind could construe what was said as

a   comment  on   appellant's  decision   not  to   testify,  the

prosecutor's words are more plausibly interpreted as a comment on

appellant's silence during  the commission of  the crime.   After
                                                                   

                                24


all, Taylor had labored to develop a defense based on his lack of

foreknowledge  concerning Lynch's felonious  intent.  Appellant's

silence throughout the commission of the crime tends to undermine

this defense, and  the prosecutor's comments  were most likely  a

clumsy effort to seize upon this weakness.

          We will  not paint the  lily.  Given  the absence  of a

contemporaneous  objection, we  must cede  to the  government the

benefit  of   a  legitimate,  plausible  interpretation   of  the

prosecutor's words.   On this basis, we  hold that the remarks in

question did not amount  to a constitutionally prohibited comment

on appellant's declination to testify at trial.

          We add that, even  if the prosecutor's comments crossed

the line,  our  traditional  three-part  analysis  suggests  that

reversal would be unwarranted.  First, although the comments were

repeated several times, there  is no reason to conclude  that the

prosecutor intentionally drew attention to appellant's silence at

trial.   Second, despite the  lack of an  objection, the district

judge  instructed the  jury with  painstaking care  regarding the

government's burden of proof, appellant's presumed innocence, and

his constitutional right to refrain from testifying.  Among other

things,  the judge admonished that "no adverse inference is to be

drawn from his exercise  of his election not to take  the stand."

We are confident that this explicit instruction was sufficient to

combat  any impermissible  inference that  might have  been drawn

from the prosecutor's statements.

          Last   but  far from least, see Mejia-Lozano,  829 F.2d
                                                                

                                25


at 274 (explaining that "the strength of the government's case is

an  important   factor  in  considering  the   likely  effect  of

borderline rhetoric")    the possibility that  the comments, even

if  misconstrued,  affected  appellant's  substantial  rights  is

diminished  by the potency  of the  government's proof.   Lynch's

testimony  was  unequivocal  and  corroborated  on  many  points.

Moreover, several witnesses to  the UST robbery noted appellant's

presence  and  described his  behavior  in  a  way that  strongly

suggested   his  complicity  in  the  crime.    In  view  of  the

substantial  evidence  against  appellant,  we   find  it  highly

unlikely that the jury could have been swayed by the prosecutor's

amphibolous remarks.11

VII.  CONCLUSION
          VII.  CONCLUSION

          We  need  go  no  further.    For aught  that  appears,

appellant was  fairly tried and  justly convicted.   The judgment

below is, therefore,

Affirmed.

     11If this were not  enough, the general principles governing
plain error review caution us in this case against exercising our
discretion  in  Taylor's  behalf.   At  worst,  the  prosecutor's
comments were  veiled and  any impermissible implication  arising
out of them was attenuated.  We do not believe  that this line of
argument could have "seriously affect[ed] the fairness, integrity
or public reputation of judicial proceedings."  Olano, 113 S. Ct.
