Adam was walking around the Garden of Eden feeling very lonely, so God asked him what was wrong with him.
Adam replied that he didn't have anyone to talk to.
God took pity on him and said he would give him a companion and she would be called woman.
He told Adam that this person would cook and wash for him and would always agree with every decision he made.
She would bear his children and never ask Adam to get up in the middle of the night to take care of them.
She would always be the first to admit she was wrong when they'd had a disagreement.
She would never have a headache, and would freely give him love and compassion whenever needed.
Adam, a bit suspiciousl of this offer, asked:
"What would a woman like this cost me?"
"An arm and a leg!".
Adam thought about this for a while and said :
"What can I get for just a rib?"
The rest is history.
