I'll put 2 of my faves here, one for each side
In the beginning, Women had 3 breasts not 2, the middle one kept getting in the way and Eve wanted it removed, so God did surgery. After, Eve asked what God what he'd do with that useless boob and God created man :P - Gerrison Keillor
Adam was lonely in the garden of Eden, so he asked God for a mate... God said to him "I'll make you the perfect woman, she'll cook, she'll clean, she'll always be in the mood, she'll be drop-dead gorgeous and smart, and she'll never say a cross word... But she'll cost you an arm and a leg"...
Adam though about this for a while, then said "What can I get for a rib?".. the rest is history
