Sexual Maturity

Little Johnny was charged with the rape of a grown woman, and though the crime seemed highly improbable, the evidence was overwhelming.
As a last, desperate move, the defense counsel came over to the witness stand, pulled down Little Johnny's pants, and grabbed his tiny penis for all to see.
"Ladies and gentlemen," the lawyer cried, turning toward the jury box, "surely you cannot believe that such a small, still undeveloped organ is sexually mature?"
Growing more agitated he went on, "How could this miniature member be capable even of erection, let alone the rape of a fully grown woman."
"WATCH IT," yelped Little Johnny. "One more shake and you'll lose the case!"
