A Norwegian took a trip to Fargo, North Dakota. While in a bar,
an Indian on the next stool spoke to the Norwegian in a friendly
manner. "Look," he said, "let's play a little game. I'll ask you
a riddle. If you can answer it, I'll buy YOU a drink. If you
can't, then you buy ME one. Okay?"

"Ja, dat sounds purty good," said the Norwegian.

The Indian said, "My father and mother had one child. It wasn't
my brother. It wasn't my sister. Who was it?"

The Norwegian scratched his head and finally said, "I give up.
Who vas it?"

"It was ME," chortled the Indian. So the Norwegian paid for the
drinks. 

Back in Sioux Falls the Norwegian went into a bar and spotted
one of his cronies, "Sven," he said, "I got a game. If you can
answer a qvestion, I buy you a drink. If you can't, YOU have to
buy ME vun. Fair enough?"

"Fair enough," said Sven. Okay, my fadder and mudder had vun
child. It vasn't my brudder. It vasn't my sister. Who vas it?"

"Search me," said Sven. "I give up. Who vas it?"

"It vas some Indian up in Fargo, ND."
