Why do we say something is out of whack? What's a whack? One day my housework-challenged husband decided to wash his sweatshirt. Seconds after he stepped into the laundry room, he shouted to me, "What setting do I use on the washing machine?" "It depends," I replied. "What does it say on your shirt?" He yelled back, "University of Oklahoma." And they say blondes are dumb.
