From Muppet Wiki

Dancing with the Stars is a television series that airs on ABC, hosted by Tom Bergeron and Samantha Harris.

Sesame Street spoofed the format as "Dancing with Triangles" in a 2007 episode, with Chris, Gordon, Maria, the Elephant, and Telly Monster as contestants, and Parody versions of judges Bruno Tonioli, Len Goodman and Carrie Ann Inaba.

Muppet Guest Spots

• October 2, 2007 - Count von Count appeared briefly in "The Counting Room" on Jimmy Kimmel's insert (voiced by Jerry Nelson), which was supposed to give viewers some insight on how the audience's votes were counted. He's forced to reset the counting, when Kimmel tells him that Mel B. and Scary Spice are the same person.

• September 28, 2009 - Gonzo and Animal. Animal appeared before Aaron Carter's and Karina Smirnoff's dance playing the drum intro before they danced to The Muppet Show Theme. Gonzo blew the trumpet at the judges' table at the end of the number, into judge Bruno Tonioli's ear. In the interview before the scores, Samantha Harris and Karina make passing reference to Kermit the Frog and Miss Piggy. (This exact same routine was performed on Ellen.)

• November 24, 2009 - Several Muppets appear on the Season 9 finale. Aaron Carter and Karina Smirnoff reprised their dance to the "Muppet Show Theme" from earlier in the season. Animal once again appeared before the start of the dance, but this time attired in a tux in honor of the occasion. Statler and Waldorf appeared in the audience to heckle Len Goodman, (Statler: I like this show. Waldorf: Why? Statler: Because of that judge in the middle! He's older than me!) And Miss Piggy interviewed past contestants Cloris Leachman, Jerry Springer, Steve Wozniak and Joanna Krupa backstage, and appeared with Maksim Chmerkovskiy backstage.
