An old man and his wife went to the doctor for a check-up. While the man is with the doctor, the doctor asks him, "So how has life been treating you?" The old man replies, "The Lord's been good to me. Every night when I go to the bathroom, he turns the light on and when I'm finished, he turns the light off." While the old woman is with the doctor, the doctor told her what her husband said. She replied, "Damn it! The old fart's been pissing in the ice box again!"
