The joke about health:
He 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, what's so frightening about that?"
"She wasn't talking to me. She was talking to the doctor!"
The pun:
Never lie to an x-ray technician. They can see right through you.
