PERFORMER Richard Hunt
DEBUT 1974

Sully and Biff

Sully is a construction worker, and a friend and colleague to Biff, who first appeared in Season 5.[1]

Sully is never heard speaking on the show, typically because the talkative Biff never lets him get a word in edgewise. Despite this, it is suggested that he is indeed capable of speech. In the song "Think of Your Fingers," Biff recalls Sully giving him advice on how to remember the number 5. Also, in Big Bird Gets Lost, while drilling loudly, Biff tells Big Bird what Sully says. Most notably, though, there was one time when Biff actually listened to what Sully had to say. This was during the introduction to "This Song is For the Birds". The only thing was, Sully whispered in Biff's ear, so we couldn't hear him. Also, in A Muppet Family Christmas, Sully can clearly be seen singing along in the big chorus numbers.

In addition to working in construction, Sully is good at playing the piano. However, Biff is sometimes oblivious to this.

In the 1990s, after Richard Hunt's death, Sully was performed by David Rudman.[2]

Although the two stopped making new appearances following 1999, the duo made background cameos in episodes 4204 and 4712. He and Biff appeared much more prominently in Episode 5017 and 5033.


  • In Episode 0606, Biff mentions that Sully is married and recently had a baby girl named Junior.
