  Honorable Joseph H. Young, United States District Judge for the District of Maryland, sitting by designation.
  HARRISON L. WINTER, Chief Judge:
  A jury found defendant guilty of bank robbery, bank larceny, and assault with a dangerous weapon during a bank robbery, in connection with the armed robbery at the Savings Bank of Baltimore in Baltimore, Maryland on October 24, 1980. In defendant’s appeal from the judgment entered on the verdict, the question presented is whether certain remarks made by the prosecutor during closing arguments to the jury constitute reversible error. We conclude that the remarks were improper and prejudicial, and that, under the facts of this case, the curative instructions given by the court were insufficient to dissipate the prejudice. Accordingly, we reverse and grant a new trial.
  I.
  The bank was robbed by three persons, two masked and one unmasked. The government sought to prove that the defendant was the unmasked robber. The government’s evidence included the bank surveillance photographs of the holdup; the testimony of three bank employees and two persons who saw the getaway car, which defendant stipulated was owned by him; and a surgical glove seized from defendant’s car. The photographs showed that one of the masked robbers wore a glove similar to the one found in defendant’s car.
  There was considerable uncertainty in the evidence identifying defendant as the unmasked robber. The bank manager described the unmasked robber as a black man with no facial hair, but could not identify the defendant at trial. One of the bank tellers made an out-of-court identification of the defendant from photographs as the one most resembling the unmasked robber, but could not identify him at trial. That teller described the robber as having had facial hair. Another teller made an in-court identification of the defendant after describing the robber as having had facial hair. She admitted that she had earlier identified him in two pictures which did not show facial hair, one of which was the surveillance photograph. Defendant’s mother testified that defendant had always worn facial hair and that he had a front gold tooth, which none of the identification witnesses had mentioned. One of the two persons who saw the getaway car could make no identification, and the other could identify only defendant’s “hair style.” The defendant did not testify.
  During closing arguments, the prosecutor noted that at one point during the trial defense counsel and defendant had, with the permission of the district court, approached and examined the blowups of the bank surveillance photographs. The prosecutor then stated:
  .. . and if you will recall, it was the defendant who was doing most of the pointing. It was the defendant who was explaining to his lawyer what the pictures were all about. It was the defendant who knew more about the pictures than the lawyer did. Now, I submit to you ... the reason he knew so much about those pictures is because he was in the bank there at the robbery. That’s the only reasonable explanation. If there was an explanation, an innocent explanation, as to why he knew more about the pictures than his lawyer did, I honestly don’t know what it is.
  In order to register an objection, defense counsel immediately asked to approach the bench, but the district judge denied the request. After the prosecutor concluded his closing argument, defense counsel again asked to approach the bench. The district judge again declined the request and, further, admonished defense counsel to restrain himself and apologized to the jury for the “outbreak.”
  In its instructions, which were given approximately thirty minutes after the challenged argument, the district court advised the jury to disregard the prosecutor’s comments on the defendant’s examination of the photographs, and explained to the jury that both defendant and defense counsel had been provided copies of the photographs prior to trial.
  II.
  It is clear that the prosecutor’s reference to the courtroom behavior of the defendant was improper. It impugned defendant’s Fifth and Sixth Amendment rights. Defendant had a Fifth Amendment right not to testify, and he elected to exercise that right. He also had a Fifth Amendment right not to be convicted except on the basis of evidence adduced against him. Defendant had not only a Sixth Amendment right to a trial by jury (and he elected to exercise that right also), but also the right to counsel, including the right to assist his counsel in his own defense. In tandem, defendant had the right to a jury trial at which, if he elected not to testify, the fact of his presence and his non-testimonial behavior in the courtroom could not be taken as evidence of his guilt.
  When, as here, the prosecutor describes the courtroom behavior of a defendant who has not testified, and then goes on to tell the jury that it may consider that behavior as evidence of guilt, the prosecutor violates those rights. Moreover, he has introduced evidence of character — courtroom demeanor — solely to prove guilt. United States v. Wright, 489 F.2d 1181, 1186 (D.C. Cir.1973). But it is forbidden to introduce evidence of the character of the accused solely to prove guilt. Fed.R.Evid. 404(a). Therefore, the prosecutor erred in asking the jury to consider defendant’s examination of the photographs as evidence of his participation in the bank robbery.
  The prosecutor compounded the error of describing defendant’s courtroom behavior as evidence of guilt when he also told the jury that it was defendant who was “explaining to his lawyer what the pictures were all about.” The record is devoid of any evidence, aside from the prosecutor’s assertion, that the defendant knew more about the photographs than did his lawyer. In Berger v. United States, 295 U.S. 78, 55 S.Ct. 629, 79 L.Ed. 1314 (1935), the Court reversed a conviction where the prosecutor claimed, without evidence in the record, that a particular witness knew the defendant, on the grounds that this statement contained “improper insinuations and assertions calculated to mislead the jury.” Id. at 85, 55 S.Ct. at 632. Similarly, here, the argument that the defendant had been at the scene of the crime because he knew more about the photographs than did his lawyer was wholly improper since there was no evidence of the latter proposition. United States v. Corona, 551 F.2d 1386, 1389 (5 Cir. 1977).
  The government argues that the prosecutor’s remarks, even if improper, were cured by the district court’s instructions to the jury. We reject the argument.
  By allowing the prosecutor’s remarks to pass uncorrected, over defense counsel’s objection, for a not-inconsiderable period of time, the district court implied that the remarks were unobjectionable. This impression was reinforced by the district court’s admonition to defense counsel and its apology to the jury for the “outbreak.”
  We do not doubt that if an improper statement, not elicited by the government, is made during trial, and if the admissible evidence of guilt is “solid and convincing,” prompt and strong curative instructions may dissipate the error. United States v. Johnson, 610 F.2d 194, 196-197 (4 Cir. 1979). The same may be true when the improper statement is elicited by the government. But this is not such a case. The issue of identification was the central issue and the government had something less than an overwhelming case. The error was reinforced by the district court’s admonition to counsel and its apology to the jury, and the curative instruction did not immediately follow on the heels of the prosecutor’s improper argument. Accordingly, we think that, despite the curative instruction, there is more than a fair possibility that the improper argument contributed to defendant’s conviction. Fahy v. Connecticut, 375 U.S. 85, 86-87, 84 S.Ct. 229, 230, 11 L.Ed.2d 171 (1963).
  REVERSED AND REMANDED.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  In some cases there is some confusion over who should be listed as the appellant and who as the respondent. This confusion is primarily the result of the presence of multiple docket numbers consolidated into a single appeal that is disposed of by a single opinion. Most frequently, this occurs when there are cross appeals and/or when one litigant sued (or was sued by) multiple litigants that were originally filed in district court as separate actions. The coding rule followed in such cases should be to go strictly by the designation provided in the title of the case. The first person listed in the title as the appellant should be coded as the appellant even if they subsequently appeared in a second docket number as the respondent and regardless of who was characterized as the appellant in the opinion.
  To clarify the coding conventions, consider the following hypothetical case in which the US Justice Department sues a labor union to strike down a racially discriminatory seniority system and the corporation (siding with the position of its union) simultaneously sues the government to get an injunction to block enforcement of the relevant civil rights law. From a district court decision that consolidated the two suits and declared the seniority system illegal but refused to impose financial penalties on the union, the corporation appeals and the government and union file cross appeals from the decision in the suit brought by the government. Assume the case was listed in the Federal Reporter as follows:
  United States of America,
  Plaintiff, Appellant
  v
  International Brotherhood of Widget Workers,AFL-CIO
  Defendant, Appellee.
  International Brotherhood of Widget Workers,AFL-CIO
  Defendants, Cross-appellants
  v
  United States of America.
  Widgets, Inc. & Susan Kuersten Sheehan, President & Chairman
  of the Board
  Plaintiff, Appellants,
  v
  United States of America,
  Defendant, Appellee.
  This case should be coded as follows:Appellant = United States, Respondents = International Brotherhood of Widget Workers Widgets, Inc., Total number of appellants = 1, Number of appellants that fall into the category "the federal government, its agencies, and officials" = 1, Total number of respondents = 3, Number of respondents that fall into the category "private business and its executives" = 2, Number of respondents that fall into the category "groups and associations" = 1.
  Your task is to identify the state of the first listed state or local government agency that is an appellant.
