From the National Journal article Rich mentioned the other day:
U.S. media presentations of the French arguments have been on a similar plane. The “cheese-eatin’” tag (would that be Brie or Roquefort?) derives from an eight-year-old episode of the animated television show The Simpsons, in which a reluctant teacher of French greets his elementary-school charges with the rousing salutation “Bonjour, ye cheese-eatin’ surrender monkeys!” It fell to a pop-culturally informed conservative polemicist, National Review scribe Jonah Goldberg, to revive and popularize the insult in the prewar name-calling. The New York Post is still calling the French “weasels.”
