In his first appearance (Episode 0487), Biff sports a wool cap rather than his usual hardhat.


Biff and his niece, Roxie Marie.

Biff is a construction worker on Sesame Street who speaks with a gruff New York accent. His partner is Sully. Biff first appeared in Season 4.

Biff often asks for Sully's opinion, but interrupts him before Sully gets a chance to even make a sound. He also tends to ask him questions and then eggs Sully on by repeating, "Huh? Huh? Huh?", a reference to a routine by comedy duo Burns and Schreiber. As performer Jerry Nelson said in an interview, "Sully wasn't so much Schreiber, but Biff was the Jack Burns character."[1] Biff often has trouble figuring out how to perform various tasks, and by the time he's figured it out, Sully has already finished it. Biff would then take the credit. While Biff normally interrupts Sully, on occasion (such as episodes 3333 and 3387) he also interrupts his niece, Roxy Marie, though she's at least able to get out some words when he does.

Besides his niece Roxy Marie, Biff's family includes his wife, Celeste, though in Episode 0558 he said he had a wife named Ethyl. According to Episode 2608, he also has four kids - Timmy, Tommy, Tammy and infant Mary-Biff. In Episode 1737, he mentions having a dog named Tuffy.

According to Episode 2294, Biff says he grew up in Canarsie (a neighborhood in Brooklyn). Biff mentions in Episode 3087 that he attended P.S. 186, where he was the self-proclaimed counting ace.

He has sung songs such as "We Coulda," "Think of Your Fingers," "This Song is For the Birds," and appeared in "Do De Rubber Duck." He also appeared with Judy Collins in the song "One Thing Leads to Another," and with Johnny Cash in "Five Feet High and Rising."

In Elmopalooza, Biff uses a jackhammer to get Jon Stewart and Prairie Dawn out of the dressing room, but when he puts it on full throttle, it shakes him all the way to the stage. Later during "One Small Voice," he and Sully appear in the audience at the talent show.

The duo made background cameos in episodes Episode 4204 (performed by John Kennedy) and 4712. In season 50, he made his first new speaking appearances in Episode 5017 and 5033, now performed by Matt Vogel.

A similarly named construction foreman, Bif, exists off-screen. Two construction worker Anything Muppets who looked similar to Biff and Sully made background appearances in the "Outrageous Makeover: Home Addition" sketch. (First: Episode 4132)
