Palm Springs, Florida (CBS12) -- Actor Ron Palillo, who's best remembered as "Arnold Horshack" on the 1970's TV series Welcome Back, Kotter, has died.
According to G-Star School of the Arts CEO and founder Greg Haupner, Palillo taught classes at the school back in 2009. No word yet on what caused the death of the 63-year-old actor.
Family friend Stacy Sacco tells the Palm Beach Post that Palillo passed away suddenly at 4:30 a.m. Tuesday.
Palillo was forever remembered for the character he played from 1975 to 1979 on the ABC sitcom: a nasally Brooklyn teen whose hand shot skyward and who barked out a string of "Ooohs" when a teacher posed a question.
Though his co-star on the show, John Travolta, went on to fame, Palillo struggled to expand beyond his role as Horshack.
Of Horshack, Palillo once told an interviewer from the Birmingham News: "While I loved him, I really loved him, I didn't want to do him forever."
