Several first grade boys overheard some junior high boys talking about a penis.
The first graders asked each other, Whats a penis? None of them knew.

Finally one boy said, Ill ask my Dad, he knows everything.

That evening the boy asked his Dad, Whats a penis?

The father replied, Well, if youre old enough to ask I guess youre old enough
to know. Dad dropped his pants and said, Thats a penis! As a matter of fact,
thats a perfect penis!

The next day the boy told his friends, I found out what a penis is, come on,
Ill show you.

The others followed him to the bathroom and watched him drop his pants. The boy,
exposing himself to his friends, said, Thats a penis! As a matter of fact, if
it was two inches shorter, itd be a perfect penis!
