role, but the character was amazing enough to have him brought back. Sideshow Bob eventually became one of the most popular roles Grammer ever played, and Bob became a recurring character on the show. Grammer bases his Bob voice on theatre actor and director Ellis Rabb. He had once worked for Rabb, whose "lamenting tones became [the] foundation for Sideshow Bob". Cultural references The episode begins with the family, except for Marge, watching a parody of the show Dinosaurs on television. The staff thought Dinosaurs was a knock-off of The Simpsons, so at one point Bart exclaims "It's like they saw our lives and put it right on screen," and points at the television screen. Before she reveals to the Simpson family that Selma's new boyfriend is Bob, Patty says there is something "disturbing" about him, which results in Lisa's imagining him as The Elephant Man.

These shots, from Bob turning the chair to Selma in the doorway, are a reference to the ending of the film Psycho. The music in the scene, written by composer Alf Clausen, is also a reference to Psycho. In Bart's retelling of the story at the end of the
