Six days after the Creation, Adam was still alone in the Garden of
Eden, and getting pretty desperate. "God!" he cried, "rescue me from
loneliness and despair! Send some company for Your sake!"
God replied "OK, I have just the thing. Keep you warm and relaxed all
the days of your life. Never complains. Looks up to you in every way.
It'll cost you though".
"Sounds ideal" said Adam. "The society of the beasts of the field and
the birds of the air palls after a while. What's the price?"
"An arm and a leg", said God.
Adam thought about it for a bit and finally sighed. "So, what can I get
for a rib?"
