hehe it's not only a British thing, i think in some other countries people also make fun of, or even dislike, French. Here in NL f.ex. people say "France is a beautiful country, it's a shame that the French live there"
Haha yeah I know most other countries of Central Europa don't like the French either, but with the Brits it's a special case because of the wars.
That's pretty similar to what I say: "The problem with Paris is that it's full of French" haha. Although Oscar Wilde did feel free to go to Paris and be as homosexual as he wanted, and died there. That's something I really respect.
