A doctor, an architect, and a computer scientist were arguing
about whose profession was the oldest.  In the course of their
arguments, they got all the way back to the Garden of Eden, whereupon
the doctor said, "The medical profession is clearly the oldest, because
Eve was made from Adam's rib, as the story goes, and that was a simply
incredible surgical feat."
	The architect did not agree.  He said, "But if you look at the
Garden itself, in the beginning there was chaos and void, and out of
that, the Garden and the world were created.  So God must have been an
architect."
	The computer scientist, who had listened to all of this said,
"Yes, but where do you think the chaos came from?"
