Trying to sell American Pizzas in Italy is like trying to sell refrigerators to the Eskimos.
I remember a joke about Inuit buying a refrigerator:
Seller asks: "Why do you even need it?"
He answers: "There's -40 degrees outside, -30 in home, -20 in bed. In refrigerator, at least my wife will warm herself".
Refrigerators can actually work as electric heaters: they produce a lot of heat at the back side in order to extract a bit of heat from the inside. If you leave a refrigerator open, heat will just flow back in and the refrigerator will convert almost all its input power into heat.
Yeah i know, this is what makes this joke better since not many people would thought about that, even thought everyone do know how warm the fridges usually are on the outside.
