I suppose you'd come back from Paris and tell your friends you'd seen the "Arch of Triumph"? (Ok, speaking of which, why do English speakers refer to "Arc de Triomphe" but not to "la Tour Eiffel"? "The Louvre Museum" but the "Musée d'Orsay"? Is post-Impressionism just that much more pretentious than art from before 1850? Ok, the answer to that one is a definite oui.)

Anyway, it's fun to break up boring old English with some randomly chosen foreign phrases. Capisce?
