Laura Bush went to the doctor

Laura Bush went to the doctor for a check up and got a clean bill of health.
When she got home George asked her, “So how did the appointment go?”
Laura bragged, “the Doctor said I have the heart and lungs of a
twenty-year-old.”
George smirked, “Oh yeah? And what did he have to say about
your fifty year old ass?”
Laura replied: “Your name didn’t come up.”
