How do I change a lightbulb?

There is no uniformity as to the target of derision: in America it has been the Polish people, while Poles poke fun at Russians and Americans. In Great Britain it is the Irish who are lampooned (in Wales it is the "Cardis"). The Australians and New Zealanders make fun of each other. The Canadians target their own Newfoundlanders, or "newfies". The jokes are by no means limited to English-speaking countries. For example, the Russians tell the same joke about the Moldovans, Chukchi and Ukrainians. The Ukrainians, in turn, tell it about Russians; the Spanish make fun of the inhabitants of Lepe, while the Colombians make fun of the inhabitants of Nariño, and the rest of the Spanish-speaking population laugh at the Galicians; the Brazilians mock the Portuguese; the Portuguese mock the Brazilians; the Norwegians laugh at their Swedish neighbours, and conversely, the Swedes tell the same joke about Norwegians; the Germans target the East Frisians or the Austrians; The Dutch and French target their Belgian neighbours, the Costa Ricans joke about foreigners from Nicaragua, and the Indians target the Pakistanis. The Finns target everyone, including themselves.
