An elderly man visits the doctor for a checkup. “Mr. Smith, you’re in great shape,” says the doctor afterward. “How do you do it?”
“Well,” says Mr. Smith, “I don’t drink, I don’t smoke, and the good Lord looks out for me. For weeks now, every time I go to the bathroom in the middle of the night, he turns the light on for me”
Concerned, the doctor finds Mrs. Smith in the waiting room and tells her what her husband said.
“I don’t think that’s anything to worry about,” she says. “And on the bright side, it does explain who’s been peeing in the fridge”
