God creates Adam, and soon Adam is complaining that he’s all alone in the Garden of Eden.

So God says, “Ok, I’ll make you a companion, a beautiful creature who’ll cook and clean for you. It will be able to converse intelligently on any subject, and never ever complain or argue.”

Adam says, “That sounds great.”

God says, “The only thing is, it will cost you an arm and a leg.”

Adam says, “Damn, that’s expensive. What can I get for a rib?”

And as they say, the rest is history.
