On "Welcome Back, Kotter," Palillo played Horshack, the class clown, who was part of an incorrigible group of students known as the Sweathogs. Some of Horshack's best-known catch phrases included, "That was very impressive, Mr. Kotter!", "Ooh-ooh-ooh!", and "Up your nose with a rubber hose." In an interview with the Associated Press, Palillo said, ""While I loved him [Horshack], I really loved him, I didn't want to do him forever.”
"Welcome Back, Kotter" ran for four seasons on ABC, from 1975 to 1979, and also starred Gabe Kaplan (as Mr. Kotter), John Travolta, and Robert Hegyes.
The young Travolta, who played "sweathog" Vinnie Barbarino, gained acclaim during the show's run, and went on to star in "Saturday Night Fever," in 1977. Robert Hegyes (pronounced Hedges) played Juan Epstein, a Puerto Rican-Jewish character who would always try to skip class with a note signed "Epstein's Mother." Hegyes died in January of this year.
Palillo also made guest appearances on such TV shows as "The Love Boat," "The A-Team," "CHIPs," and "Murder She Wrote."
Palillo was born on April 2, 1949, in Cheshire, Conn. He attended the University of Connecticut, after which he lived in New York City for about four decades, until his recent move to Palm Beach County, in 2009, according to The Palm Beach Post.
In 2009 he hold The Post that he loved Palm Beach County, where he served as artistic director for the Cuillo Centre for the Arts, for which he directed and acted in "A Closer Walk with Patsy Cline" and "The Phantom of the Opera."
Palillo had been teaching acting classes at G-Star School of the Arts, a charter school in Palm Springs, Fla., for about three years, according to The Palm Beach Post.
Palillo is survived by his partner of 41 years, Joseph Gramm, a retired actor.
