Joseph "Joey" Mazzarino (b. June 4, 1968) is a puppeteer and writer who started working with the Muppets in 1989. He joined the Sesame Street team in 1990, initially as a performer, but shortly after became a writer beginning with Season 23 (1991). He wrote his first sketch for the show, the Columbo parody "Colambo," as an audition piece, and soon found himself cast in the title role. He was promoted to head writer in Season 40.
With an inclination toward ad-libbing and a reputation as a cut-up on set, Mazzarino became a prominent player in the current Sesame Street cast. His recurring characters have included Murray Monster, Stinky the Stinkweed, Papa Bear, and the boisterous, tutu-wearing Elephant. In 2001, he took over the left head of the Two-Headed Monster. Mazzarino received his first Daytime Emmy nomination for the Outstanding Performer in a Children's Series in 2010.
Mazzarino's writing credits include Bear in the Big Blue House and the non-Muppet series The Upside Down Show and Sheep in the Big City (which was created by former Sesame Street writer Mo Willems, and for which he also did voice-overs). He also co-wrote the screenplays for The Adventures of Elmo in Grouchland, Muppets from Space and Kermit's Swamp Years.
In September 2015, Mazzarino announced on his Facebook page that he had left his position on Sesame Street; Season 46 had been recorded prior to his departure. He since worked on the Jim Henson Company production, Julie's Greenroom, as a writer and director. Mazzarino also participated in the 2018 Puppets for Puppetry event honoring Caroll Spinney, performing a Muppet version of Bozo the Clown.
