A man dies and goes to Heaven. When he arrives he sees that there is a long line to the Pearly Gates. After some time he hears a commotion behind him and turns to see a man in a long white coat with a stethoscope in the pocket cutting past everone. He strides right through the gates without a pause and past everyone who had been waiting forever.

When the man gets to St. Peter he says, "Say, who was that guy who cut past everybody and walked right through?"

St. Peter replied, "Oh. That's God. Sometimes he likes to think he's a doctor."
