What is the oldest profession?

Representatives of different professions in a Christian country were debating which profession is the oldest. The medical doctor said "What was the first thing that God did with humans? He performed an operation- he made Eve with Adam's rib. The medical profession is the oldest".

The politician, who was patiently listening, grinned and asked: "Who created that chaos?"
