A Swedish, a Danish and a Norwegian windowwasher was eating their lunch on the outside of the 17th floor of a skyscraper. Before they had opened their lunch packets, the Dane said, "if it is ham on my lunch, I will jump off." He opened his lunch, and discovered that it was ham on it, and he jumped off. The Swede said, "if it is cheese on my lunch, I will jump off." He opened his lunch, and discovered that it was cheese on it, and he jumped off. Then the Norwegian said, if it is fish on my lunch, I will jump off too." He opened his lunch, and discovered that it was fish on it, and so he jumped off too. After the burial, the widows of the Swedish, the Danish and the Norwegian windowwashers met, and talked together. The Danish widow said, "I don't understand anything, I thought he loved ham on his lunch." The Norwegian widow also said, "I don't understand anything, I thought he loved fish on his lunch." And the Swedish widow said: "I don't understand anything either, he made his lunch himself.."
