A Polish took a trip to Warsaw. While in a bar, an Indian on the next stool spoke to the Norwegian in a friendly manner.
"Look," he said, "let's have 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. OK?"
"Ja, dat sounds purty good," said the Polish.
The Indian said, "My father and mother had one child. It wasn't my brother. It wasn't my sister. Who was it?"
The Polish scratched his head and finally said, "I give up. Who vas it?"
"It was ME," chortled the Indian.
So the Polish paid for the drinks.
Back in Poznan the Polish went into the bar and spotted one of his cronies.
"Sven," he said, "I got a game. If you can answer a question, I'll buy you a drink. If you can't, you have to buy me vun. Fair enough?"
"Fair enough," said Sven.
"Ok," the Polish said, "my father 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?"
The Polish burst out, "It vas some Indian up in Warsaw!"
