God says to Adam, "What would you like in a wife?"
"Hmmm," says Adam, "I'd like her to be the most beautiful creature in the world. I'd like her to do whatever I tell her to. I'd like he to work hard, be smart, enjoy being with me."
"Hmmmm", God says, "I can do it, but it'll cost you an arm and a leg."
"Oh," says Adam, "Well what can I get for a rib?"
