There was a traveling salesman whose car became stuck in a snow bank during a recent blizzard in North Dakota. It took him several hours to make it to the nearest farmhouse. Frozen half to death, he finally reached the front door and knocked.

A grizzled old farmer answered, and the salesman pleaded to spend the night.

"Why, sure, young fella, I can give ya a place to bunk," said the hospitable old man. "But I ain't got no daughter for ya to sleep with like ya always hear about in them thar jokes."

"Oh," said the salesman. Then thinking a moment or two, he said, "Just how far is it to the next house?"
