A man was seen fleeing down the hall of a hospital just before his operation.
"What's the matter?" his wife asked.
"I heard the nurse say, 'It's a very simple operation. Don't worry. I'm sure it will be all right," he said.
"She was just trying to comfort you," his wife said "What's so frightening about that?"
"She wasn't talking to me," he answered. "She was talking to the doctor."
