A five-year old boy asked his friend what a penis was. His friend's response was that he did not know and he would ask his dad. That evening the second boy asked his dad. His dad gladly exposed himself to his son and, holding his penis in one hand said, "Son, this is a penis. In fact. if you take a closer look you will notice that this is a perfect penis." The next day the boy saw his friend at recess and called him behind a hedge. The boy exposed himself and whispered. "This is a penis. In fact. if it were three inches shorter it would be a perfect penis."
