Was "God" in heaven, busy creating things for the Earth and he just finished creating the first fish. So he released it on a river. The fish swam downstream and met Eve, who was taking a little bath. The fish approached Eve and she started to play with it, all joyfull... then the fish started to swim arround and between Eve's legs and she discovered it was even more "fun" than before... They kept playing their new-found game for a while and then the fish swam away and continued it's way downstream.
"God" that was looking all of this, brought his hand to his forehead and sighed deeply:
-Oh, good Heavens!! Now I'll never be able to remove THAT SMELL from it!!
