Joseph "Joey" Mazzarino (b. 1968) has been a writer and performer on Sesame Street since 1990. 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 has become a prominent player in the current Sesame Street cast. His recurring characters include Murray Monster, Stinky the Stinkweed, Papa Bear, and the boisterous, tutu-wearing Elephant. In recent years he has also taken over one half 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.
