Dr. Octagon classical sample question

[ironwizard]

I wasn´t sure whether to put this in hiphop or sound shack, but since the piece of music I´m looking for is classical, I´ll post it here.

Anyway, my question is this: Does anyone know which piece of classical music
Dan the Automator sampled the skit "I got to tell you" on "Dr. Octagonacologist? This is the skit: http://www.youtube.com/watch?v=eYvh3zfJOlk

Hope anyone can help me with this.
Thanks in advance

starts around 2:02, beautiful song

[Come Honor Face]

Shit is mesmerizing. One of my favorite classical songs.
