The Simpsons/Sideshow Bob

Sideshow Bob Terwilliger (voiced by Kelsey Grammer) is /Krusty the Klown's silent (during the Krusty show) sidekick. Angered by being overshadowed by Krusty's "dilapidated vaudeville antics", he snapped and has tried to kill Krusty, /Bart (for exposing his plan and landing him in jail), and indeed everyone in Springfield several times, but has failed through a combination of luck and Bart and /Lisa's efforts. Was briefly married to /Selma (whom he also tried to kill). Grammer's Frasier? costar [David Hyde Pierce]? made an appearance in one episode as Sideshow Bob's brother Cecil.

Replaced as Krusty's sidekick by /Sideshow Mel.
