After Adam was created, there he was, all alone, in the Garden of Eden.
Of course it wasn't good for him to be all by himself, so the Lord came down to visit.
"Adam," He said, "I have a plan to make you much, much happier. I'm going to give you a companion,
a help mate for you - someone who will fulfil your every need and desire.
Someone who will be faithful, loving and obedient. Someone who will make you feel wonderful every day of your life."
Adam was stunned. "That sounds incredible!"
"Well, it is," replied the Lord. "But it doesn't come for free. This is someone so special that it's going to cost you an arm and a leg."
"That's a pretty high price to pay," said Adam. "What can I get for a rib?"
