"In the middle of the night, George was pacing back and forth in his room, unable to sleep. This woke his wife, who asked him why he couldn't sleep. He replied, "You know that thousand dollars I borrowed from Bob next door? Well it's due tomorrow, and I don't have it, and I'm anxious and can't sleep." His wife said, "Honey, I have the solution." She opened up the window and yelled to the house next door. "Bob, wake up." A light went on in the house next door and Bob stuck his head out of his window. She continued, "You know that thousand dollars my husband owes you? Well he doesn't have it!" Then she closed her window and turned to her husband. "There, now let him pace the floor and you go to sleep."
