A man was seen fleeing down the hall of the hospital just before his operation. A security guard stopped him before he could leave the hospital and asked, "What's the matter?"

The man said, "I heard the nurse say, ‘It's a very simple operation, don't worry, I'm sure it will be all right.'"

"She was just trying to comfort you," said the security guard. "What's so frightening about that?"

"She wasn't talking to me," exclaimed the man. "She was talking to the doctor!"
