--In France they use all different kinds of salad dressings, and the dressing we see at the local Safeway as "French Dressing" is merely some nasty american concoction, which as far as I know, no one has ever actually eaten.
--The Simpsons episode where Bart becomes a foreign exchange student in France does not, in fact, accurately represent living conditions in modern France. I am beginning to think that I might have to base my ethnocentric world-views on some other program!
--French Fries are not actually French in origin. In France they just called the "fried potatoes", in fact french fries were mistakely named that because they were invented in Paris, Texas, and a newspaper reporter mistook a reference to Paris, as one to the French city of the same name.
