"Felix died just a few hours ago and the only good I can draw from his passing is that he didn't suffer any longer."

He added, "I will miss him terribly especially the time we had at our panels. Just telling me to 'go 'f' myself.'"

The actor's death comes after his battle with pancreatic cancer.

He is survived by his wife, Sue, whom he wedded in 1965, and their kids, Bonnie and Michael.

Playing the role for the series was hit most notable yet.

The Italian-American made its debut in an episode where a zookeeper wanted to lock him up in a cage and later appear on the show 16 more times.

In an interview in 2014 about his role in the show, he revealed that his costume was initially made out of natural human hair, making it heavy and almost explosive.

He revealed, "All the guys on the set smoked."

"They just dropped their butts and stepped on them. The producers are worried that it might step on a smoldering cigarette and go up in flames."

In the end, they gave him some synthetic hair.
