The courtroom went wild when Malone finished; Scopes declared Malone's speech to be the dramatic high point of the entire trial and insisted that part of the reason Bryan wanted to go on the stand was to regain some of his tarnished glory. On the sixth day of the trial, the defense ran out of witnesses. The judge declared that all the defense testimony on the Bible was irrelevant and should not be presented to the jury (which had been excluded during the defense). On the seventh day of the trial, the defense asked the judge to call Bryan as a witness to question him on the Bible, as their own experts had been rendered irrelevant; Darrow had planned this the day before and called Bryan a "Bible expert". This move surprised those present in the court, as Bryan was a counsel for the prosecution and Bryan himself (according to a journalist reporting the trial) never made a claim of being an expert, although he did tout his knowledge of the Bible. This testimony revolved around several questions regarding Biblical stories and Bryan's beliefs (as shown below); this testimony culminated in Bryan declaring that Darrow was using the court to "slur the Bible" while Darrow replied that Bryan's statements on the Bible were "foolish". On the seventh day of the trial, Clarence Darrow took the unorthodox step of calling William Jennings Bryan, counsel for the prosecution, to the stand as a witness in an effort to demonstrate that belief in the historicity of the Bible and its many accounts of miracles was unreasonable. Bryan accepted, on the understanding that Darrow would in turn submit to questioning by Bryan. Although Hays would claim in his autobiography that the examination of Bryan was unplanned, Darrow spent the night before in preparation. The scientists the defense had brought to Dayton—and Charles Francis Potter, a modernist minister who had engaged in a series of public debates on evolution with the fundamentalist preacher John Roach Straton—prepared topics and questions for Darrow to address to Bryan on the witness stand. Kirtley Mather, chairman of the geology department at Harvard and also a devout Baptist, played Bryan and answered questions as he believed Bryan would. Raulston had adjourned court to the stand on the courthouse lawn, ostensibly because he was "afraid of the building" with so many spectators crammed into the courtroom, but probably because of the stifling heat. An area of questioning involved the book of Genesis, including questions about whether Eve was actually created from Adam's rib, where Cain got his wife, and how many people lived in Ancient Egypt.
