Joe Besser
When Shemp Howard died in 1955, Besser was tapped as his replacement in the Three Stooges, but his nervous-nellie shtick didn't really mesh with the more knockabout slapstick of Moe Howard and Larry Fine. When the Stooges ended their affiliation with Columbia Pictures (with whom Besser had been under contract in the 30s and 40s) in 1958, he was dropped in favor of 'Curly' Joe DeRita. For Besser, that turn of events proved favorable as he went on to a career as a character player in films and TV. He co-starred as the building superintendent Mr. Jillson on the ABC sitcom "The Joey Bishop Show" from 1962 to 1965 and made memorable guest appearances on shows like "Batman" and "Love American Style." For much of the 70s, he provided character voices for animated series, many produced by Hanna-Barbera.
