God said, "I can make a woman for you."
Adam replied, "What is a woman?"
God said "She will be beautiful, never spend your money without asking, bear your children and never ask you to get up with them. She will never have a headache when you feel amorous."
Adam asked, "What what will it cost me?"
God replied, "An arm and a leg."
Adam thought for a moment, then asked, "What can I get for a rib?"
