After God had created Adam he noticed that he looked very lonely. He
decided to help.
He said, "Adam, I've decided to make you a woman. She'll love you,
cook for you, be sweet to you, and understand you."
Adam said "Great! How much will she cost me?"
The answer came back, "An arm and a leg."
"Well," said Adam "what can I get for a rib?"
