If anyone here is knowledgeable in opera, I would love to know what is the passage of opera that is sung by the coloratura soprano (might even be a mezzo-soprano) in the new Van Huesan stain resistant shirts ad. My guess is that the particular passage has something which humorously relates to stain-resistance, but, of course taken from a famous opera. I wonder if it isn't a typical Wagnerian piece in which the opera is over because the "fat lady is singing." I know the humor in that would be a stretch. Also, I figure most TV viewers would never make a connection between the music and the ad which shows a dark liquid being poured over a series of dress shirts without staining them. I bet very few viewers can identify random passages of opera without any clues or even with clues.
