The Muppets' own Gonzo and Animal made a surpise appearance on ABC's Dancing with the Stars last night. Aaron Carter and Karina Smirnoff danced the quickstep to "The Muppet Show Theme". Animal provided an opening drum solo, while Gonzo closed the number with the blow of a trumpet. You can watch the entire appearance and Carter and Smirnoff's dance in the video below. Enjoy!
