Ron Palillo, best known as mouthy classroom goofball Arnold Horshack on the 1970s TV series Welcome Back, Kotter, died at his Palm Beach Gardens home early this morning, according to Stacy Sacco, Palillo’s friend.

Sacco said Palillo passed away suddenly at 4:30 a.m. He was 62.

This comes nearly eight months after fellow actor Robert Hegyes — who portrayed Juan Epstein — passed.
