Well, SOME are funny. This one for instance:
So, there were an Irishman, an Englishman and an American wrecked on an island. One day, they found a bottle, and when they opened it, a ghost came out and offered them each a wish. However, even though they wished for different stuff, nothing happened, as the three guys of varying nationalities were just having shared hallucinations from hunger.
But it really, really sounds like him.
