French Fries were actually invented in Belgium, so it's more accurate to say it's Belgian Fries... Story has it that Americans(during war) called it "French" thinking they were in France, when actually, they are in French speaking part of Belgium...
actually, it comes from frenched fries (When vegetables such as beans, peppers or potatoes are cut into long thin strips, the preparation process refers to the vegetables as being "drenched".)
I wanna clear up something. In our Belgian Constitution it states that everybody has the right to speak whatever language they want in Belgium. However, that does not apply when you go to government buildings, courthouses, police... ;) So feel free to speak whatever you want. Remember that alot of us Belgians speak English to, not always really well but enough to hold a conversation ;)
