Special to Newsday Updated June 9, 2015 8:06 AM Print Share Share Tweet Share Email "Simpsons" psycho Sideshow Bob will evidently achieve his longtime wish to kill young Bart Simpson, says executive producer Al Jean. The dastardly act will take place this fall during the show's annual "Treehouse of Horror" Halloween special. "It's a segment where if you tune in . . . you're going to see Sideshow Bob do something he's wanted to do for a long time," Jean said with a laugh during an ATX Festival panel in Austin, Texas, over the weekend. He explained, "I'm one of the people that always wanted the Coyote to eat the Road Runner," referring to the Warner Bros. cartoon characters, adding, "When I was a kid, I wanted the rabbit to get the Trix" in the TV commercials for that cereal. "I hated frustration comedy, so we'll scratch that itch on the Halloween show, which is very funny." But since the "Treehouse of Horror" specials have always taken place in their own highly imaginative universe, independent of the series' continuing story lines, Bart will be alive and well when "The Simpsons" resumes its regular episodes the following Sunday. On "The Simpsons," Sideshow Bob -- real name Robert Underdunk Terwilliger, PhD, voiced by Kelsey Grammer -- debuted in a nonspeaking role in the eighth episode, "The Telltale Head," in February 1990. A stooge on Krusty the Clown's children's show, the disgruntled Bob attempts to frame Krusty for a robbery four episodes later, in "Krusty Gets Busted," but is exposed by Bart (voice of Nancy Cartwright) and jailed -- vowing vengeance on the eldest Simpsons child. After being released from prison, he marries Bart's Aunt Selma as part of a plan to kill her in "Black Widower" (April 1992), but is again foiled by Bart. Following his parole in Season 5's "Cape Feare," Bob begins his formal campaign to kill his nemesis. He has gone on to appear in at least a dozen more episodes, sometimes in only a cameo. Twenty-six "Treehouse of Horror" episodes have run from 1990 to 2014. By FRANK LOVECE. Special to Newsday Share on Facebook Share on Twitter Comments Comments section is temporarily on hold.
