A traveling salesman's car breaks down on a country road one evening. He is miles from town. He walks to a nearby farm house, and the farmer doesn't have a phone, but says he'll take the salesman into town in the moring.
Since the salesman isn't going anywhere, the farmer offers to put him up for the night. The condition is that he'll have to sleep with his daughter because there aren't any other beds. He is warned to behave himself.
