On last night's Colbert Report, Stephen's three-part Raging Art-On series concluded with the auction of his arted-up portrait. But before the auction began, he got psyched up by dancing to some Snoop Dogg with Simon de Pury. Given the impressive sale price of the portrait, don't be surprised if you see Cindy Sherman getting down to some West Coast hip-hop before her next piece goes up for auction.

If you missed the first two Raging Art-On segments, you can find them after the jump.

Of course, the best part about all of this is it helps support an excellent cause. To make your own contribution, visit DonorsChoose.org today.
