Adam was walking around the Garden of Eden feeling very lonely, so God asked Adam, "What is wrong with you?" Adam said he didn't have anyone to talk to. God said he was going to give him a companion and she would be called "woman."
God said, "This person will cook for you and wash your clothes, she will always agree with every decision you make. She will bear your children and never ask you to get up in the middle of the night to take care of them. She will not nag you, and will always be the first to admit she was wrong when you've had a disagreement. She will never have a headache, and will freely give love and compassion whenever needed."
Adam asked God, "What will this woman cost?"
God said, "An arm and a leg."
Adam said, "What can I get for just a rib?"
