Three people, a doctor, an engineer and a politician were arguing over whose contribution to humankind was greatest.

The doctor said, "the Lord created Eve from Adam; it was a surgical procedure, therefore we doctors were there from the creation!"

"No way," the engineer interrupted. "Go back a step: the Lord created the universe from chaos. That was the greatest engineering feat in history! MY profession was the one that was there at the beginning!"

"Fair enough," the politician piped in. "But who do you think created all that chaos in the first place?"
