An old couple go to the doctor for their yearly physicals. One-at-a time the doctor brings them into the examination room, starting with the husband.

"Well, Mr. Smith, you're in great shape for a man your age," says the doctor. The man replies, "Well doc, I don't drink, I don't smoke, and the good Lord looks out for me." "What do you mean?" asks the doctor. The old man says, "For instance, last night in the middle of the night, I had to get up to go to the bathroom--and the good Lord turned on the light for me so I wouldn't fall down." "That's nice," said the doctor. "Send your wife in now, please."

The wife comes in and the doc says, "Mrs. Smith, you're in great shape for a woman your age." She then says, "Well, doc, I don't drink, I don't smoke..." The doctor interrupts, "and the good Lord looks after you, right?" The woman is confused and says, "What are you talking about?" The doctor explains, "Your husband was just telling me the same thing--he said that the good Lord looks after him--like the other night when he had to go to the bathroom, the good Lord turned the light on for him..." "Bloody hell!" she said, "he peed in the refrigerator again!"
