A Rib
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, " I was going to give you a companion and it would be a woman."
God continues:
"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 you love and compassion whenever needed.
Adam asked God, " What would a woman like this cost me??"
God said, "An arm and a leg."
Adam asked, "What can I get for just a rib???"
And now you know...the rest of the story. :)
