There was a guy looking for the perfect girl to marry.
He took one out and they got to the moment of carnal knowledge and he asked her is she knew what this is(pointing to dick).
She said sure, it's a penis.
Guy thought that's nice, but a little to naive.
Next girl, same situation and question.
She said that's a peepee.
He said no, that's a dick, thinking she might be a little naive and young also.
She said no, a dick is about a foot long and black!
Moral of story; if you ain't big enough to be recognized, you're a peepee.
