Tu-thumbs buys a used paint sprayer from the local paint store. The sprayer had a large sign on it that said “ASĀ IS.” The dealer made no promises or statements concerning the performance of the paint sprayer. When Tu-thumbs attempts to spray paint his house, the trigger on the sprayer sticks in the “on” position and before Tu-thumbs can pull the electrical cord to cut the power, paint is sprayed all over his prize Borzoi dog that is scheduled to be shown in a dog show the next day. Tu-thumbs sues the dealership. Who wins?
