A Nurse Dies and Goes to Heaven....

A nurse dies and goes to heaven. She is met at the Pearly Gates by St. Peter who asks her questions about her life. Over St. Peter's shoulder the nurse spots a man in a white coat sitting on a cloud with a stethoscope around his neck. "Oh brother!" she cries. "Is that a doctor?" St Peter glances over his shoulder and says, "No, that's God. He just thinks he's a doctor."
