Ron Palillo, Welcome Back Kotter's Horshack, Dies at 63

Ron Palillo, who played Arnold Horshack on the 1970s sitcom Welcome Back, Kotter, passed away this morning from an apparent heart attack at his home in Palm Beach, Florida. He was 63 years old.

Palillo played goofball Horshack on the ABC series from 1975 to 1979 alongside Gabe Kaplan and a young John Travolta. Horshack's trademark was raising his hand excitedly in class and saying, "Ooh ooh ooooh!" when he thought he knew the answer to one of Mr. Kotter's questions.

After Kotter, Palillo did a lot of voice acting and played the multicolored talking puzzle box in the trippy animated series Rubik, the Amazing Cube. He also taught at the G-Star School of the Arts.
