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, "Whats the matter?"

He said, "I heard the nurse say, Its a very simple operation, dont worry, Im sure it will be all right."

"She was just trying to comfort you, whats so frightening about that?"

"She wasnt talking to me. She was talking to the doctor!"
