"Bonjour, you cheese-eatin' surrender-monkeys."
HOMER: You said the Lord told you to lead the French army to WHAT???
LISA: Victory
HOMER: We're french! we don't even have a word for that!
then there's the episode where Homer goes to work for a James Bond-style villian as he's preparing his superweapon of destruction.
HANK SCORPIO: By the way, Homer, which is your least favorite country? Italy, or France?
HOMER: Umm... France.
SCORPIO: Heh heh heh. No one ever says Italy.
