So this guy went home to ask his dad, "Dad, what's a penis?" The dad said, "well, if you old enough to know, then you should know. Come." Then the Dad took off his pants and showed the penis to his first grade son. "There, this is penis. And a perfect one at it."
So the next day, the first grade shared the info with his friends. He said, "come on, let me show you what a penis is." Then they went to the toilet and the first grade took off his pants. The first graders were awed by the info and they said "wow, so that's a penis".
Then the boy added, "and it will be a perfect penis if it is two inches shorter."
