A couple drove their car to K-Mart. Their car broke down in the parking lot. The man told his wife to go on with the shopping while he fixed the car there in the lot. The wife returned later to see a small group of people near the car.
On closer inspection she saw a pair of male legs protruding from under the chassis. Although the man was in shorts, they had ridden up his legs, and his lack of underpants had turned his private parts into glaringly public ones.
Unable to stand the embarrassment she dutifully stepped forward, quickly put her hand up his shorts and tucked everything back into place. On regaining her feet she looked across the hood and found herself staring at her husband who was standing idly by. The poor mechanic under the car had to have three stitches in his head.
