A man was wheeling himself frantically down the hall of the hospital in his wheelchair, just before his operation. A nurse stopped him and asked, "What's the matter?"
He said, "I heard the nurse say, 'It's a very simple operation, don't worry. I'm sure it will be all right."
The first nurse said, "She was just trying to comfort you. what's so frigtening about that?"
Patient: "She wasn't talking to me. She was talking to the doctor!"
