A doctor dies and goes to heaven. St. Peter meets him at the Pearly Gates and checks him in. After he's registered, St. Peter says to him, "Look at the time: you must be hungry! Heaven Cafeteria is serving lunch, why don't you get yourself something to eat?"

The doctor goes to the cafeteria and notices the long line. He immediately cuts in at the front, only to hear loud protests. "I'm a doctor" he says, "I'm a busy man, I don't have time to wait in line."

The others say, "You're in heaven now, we're all the same here, get to the back of the line and wait your turn!"

A few weeks later, waiting patiently on line for lunch, the doctor notices a man come dashing in wearing scrubs and a lab coat, stethoscope around his neck. He butts in at the head of the line and no one utters a peep. "Hey," he says to the guy in front of him, "Who does that guy think he is?"

"Oh, that's God," says the guy, "He likes to play doctor."
