A guy was sitting quietly reading his paper when his wife walked up
 behind him and whacked him on the head with a newspaper.
 "What was that for?" he asked.
 
 "That was for the piece of paper in your pants pocket with the name
 Mary Lou written on it," she replied.
 
 "Two weeks ago when I went to the races, Mary Lou was the name of one
 of the horses I bet on," he explained.
 
 "Oh honey, I'm sorry," she said. "I should have know there was a good
 explanation."
 
 Three days later he was watching a ballgame on TV when she walked up
 and hit him in the head again, this time with the iron skillet, which
 knocked him out cold.
 
 When he came to, he asked, "What the hell was that for?"
 
 She replied "Your dam horse called."
