Once upon a time there was a young boy and his dad. They were fishing. The boy had to go to the bathroom, so the dad took him behind a bush. The boy watched the dad go, and said, "what's that?" The dad said, "this is a penis. In fact, this is a GREAT penis." The boy went home. He went to school. He took several of his friends behind the locker room. Pulling down his pants he told his friends, "this is a penis. In fact, if it were three inches shorter, it would be a GREAT penis."
And there ya go.
