A guy is reading his paper when his wife walks up behind him and smacks him on the back of the head with a frying pan.
He asks, "What was that for?" She says, "I found a piece of paper in your pocket with Betty Sue written on it." He says, "Jeez, honey, remember last week when I went to the track? Betty Sue was the name of the horse I went there to bet on." She shrugs and walks away. Three days later he is reading his paper when she walks up behind him and smacks him on the back of the head again with the frying pan. He asks, "What was that for?" She answers, "Your horse called."
