Adam was in the Garden of Eden feeling lonely when he decided to ask God a favor.
Adam said, "I am lonely. Could you make me a companion to share my life with?"

God replied, "What do you have in mind?"

Adam said, "I would like a female with beautiful eyes, shiny hair, and soft skin. Someone who will never get tired of me and never argue with me. Someone who I can talk to endlessly about football. You know, someone I will want to be with forever.

God said, "Sure, I can do that for you, however it will cost you an arm and a leg."

Adam said, "Well, what can I get for a rib?"
