He was 86. Callas was famous for his rubbery face and the hysterical sounds he made to accompany his jokes, and he went on to voice the animated dragon in the 1977 Disney film, Pete’s Dragon. During his long career, he opened for Frank Sinatra, roasted Don Rickles, and became possibly the only person to ever upset the unflappable Johnny Carson on The Tonight Show.
