@Hyolobrika That's why I said truthful. I don't think you should be able to misdirect people, but if it was suspected that a statement like I'm a normal guy would misdirect the jury then I would expect the prosecution to object or the judge to step in. I don't see how that would be the case in at least this situation.

Avoiding a prejudicial jury is why we have jury selection isn't it? By the time you are on the jury and listening to the case it's your job to judge, so it's not really prejudice if an argument sways you in favor of the defendent.
