What is the opera piece that is playing in the Kohler commercial?microsoft money

I've looked for it several times and cannot find it. The one that shows up has the guy trying to clog the toilet so that he can call the pretty plumber.

I know the commercial you're asking about, but I don't recall which opera.

Is there a list for the commercials? I looked around with no luck.
