God is walking through the Garden of Eden one morning, when he sees Adam sitting by himself, grinning from ear to ear.

God says to Adam, "you're looking very happy this morning! Has something good happened?"

"Oh yes" Adam replies. "This morning we found out why I have a penis and Eve has a vagina! It was awesome. We're going to call it 'sex'!"

God is shocked. "Adam, what you have done is a sin! You and Eve must both be punished." He looks around. "Where is Eve anyway?"

Adam replies "well, she enjoyed it so much she wants to do it again. She's down by the river washing her vagina."

"Oh, great" God replies. "Now, on top of everything else, all the fish will smell funny too!"
