Arnold Stang, a character actor whose bespectacled, owlish face and nasal urban twang gave him a singular and recognizable persona, whether on radio or television, in the movies or in advertisements, or even in cartoons, died of pneumonia on Sunday in Newton, Mass. He was 91 and lived in Needham, Mass.
His memorable moments as an actor were oddly varied signposts of popular culture. He was the spokesman for Chunky, the candy bar, in the 1950s, delivering the slogan: “Chunky! What a chunk o’ chocolate!” He also played Frank Sinatra’s pal Sparrow in "The Man With the Golden Arm" and voiced the title character in 1960s animated series "Top Cat."
