One day Adam was sitting in the Garden of Eden looking sad.
God asked of him, "What is wrong Adam?".
Adam replied, "I'm lonely".
"I'm sorry to hear that! Would you like to have a companion that caters to your every need, never complains, never gets jealous, gives you space to think, and tells you calmly what is on her mind without expecting you to mind-read?"
"Yes, please Lord but how much will it cost me?", asked Adam.
"An arm and a leg", God replied.
"Oh my, that is so much; what can I get for a rib?".
The rest, as they say, is history.
