section::::regular sketches.:will it float?









































an item is dropped into a tank of water by two models, often referred to by letterman as "the hi-ho girls." the segment starts out with kalter identifying a household item that will be tested, and a faux prize that is supposedly at stake. a picture of that prize is flashed on screen for a split second. letterman and shaffer debate the buoyant properties of the item before they each decide on whether it will sink or float (a frequent deciding factor is the nature of the item's container).
