|Little Johnny and Mary were playing in the backyard when Mary asked, "Johnny, what's a penis?"|
"I don't know," replied Little Johnny, "but I'll ask my dad. He knows everything."
Little Johnny found his father in the bathroom and asked his question.
"Well, son, it's hard to explain. Why don't I just show you?"
He pulled down his pants and displayed his member, "Johnny, that's a penis. In fact, that's a perfect penis."
Little Johnny thanked his dad and returned to the backyard.
"Well," asked Mary, "did your daddy know?"
"Yes," replied Little Johnny, "But it's hard to explain. Why don't I just show you?"
He led Mary into the garage, dropped his shorts and said, "Mary, this is a penis... and if it was three inches shorter, it would be a perfect penis!"
