Don't forget the Largo al Factotum from the Barber of Seville, probably the most famous aria in all opera. If you wanted anything done in Seville, Figaro was your man.
Is that the "Figaro, Figaro, Figaro, Figaro, Figaro, Figaro" one?
Believe it or not Wikipedia has a nice little entry on the subject, including text and translation.
(In other words, Yes.)
If it's the most famous aria in opera how much of that fame is due to Bugs Bunny?
Most of my appreciation of opera and classical music came from watching Looney Tune Cartoons.
