...about the doctor, engineer, and programmer who were debating what the world's oldest profession was (other than the obvious one)? The doctor said that medicine was the oldest because the Lord performed surgery in the removal of Adam's rib. The engineer countered that before that act, the Lord had performed feats of engineering by creating the earth and heavens from nothing.
The doctor conceded that the engineer was right and that engineering was indeed the oldest profession. But then the programmer interjected that programming was even older. He was chided by both the doctor and the engineer saying that engineering had to be the oldest, because before the Lord engineered the earth and heavens, there was nothing, only the Great Void, only Chaos!
The programmer simply smiled and said:
"Where do you think the Chaos came from?"
