A couple lived on a remote farm. One winter's night there was a particularly heavy snowfall, so much so that the woman was unable to make it home. When she arrived the next morning, she told her husband that she had stayed at friend's house. Suspicious, he phoned round her ten best friends and one of them did, in fact, confitm that she had stayed over.

The next winter. It was the husband's turn to get stranded and claimed to have stayed over with one of his drinking buddies. When his wife phoned round his ten best friends, six of them confirmed that he stayed with them and two reckoned that he was still there.
