Voice of Yakko Warner performs "Yakko's World"

Here's a 2005 video of Rob Paulsen, who was the voice of Yakko Warner on the amazing Animaniacs cartoon, performing "Yakko's World," a fiendishly difficult and delightful Gilbert & Sullivanesque recital of the nations of the world set to the tune of the "Mexican Hat Dance." The song is from a 1993 episode of the show, and Paulsen's got near-perfect recall of it 12 years later.
