Biography Edit

Early life Edit

When he was young, Cecil was ignored repeatedly by his parents, and instead compared to Bob, similar to the rest of his life.[1]

Cecil's dream since childhood was to become Krusty the Clown's sidekick on The Krusty the Clown Show.[2] Cecil spent, according to Bob, "four years at clown college", to which Cecil replies, "I'd thank you not to refer to Princeton that way". Krusty and the producers of his show rejected Cecil during his audition. Cecil offered to perform his prepared "pie-in-the-face take" before he was ushered off-stage, but this did not change the producers' minds as Cecil lacked the dignity necessary to pull the bit off. It was then that Krusty spotted Robert, standing to the side in a fine suit and looking like he genuinely didn't want to be there. Krusty ordered a pie-in-the-face for him, the resulting impact knocking off Robert's top hat and causing his hair to spring up from under it, Krusty hired Robert as his sidekick on the spot. Cecil resented and was jealous of his brother, His birthday is also on May 18, 1973.

Springfield Dam Plot Edit

When Sideshow Bob was released from prison, Cecil hired him to work for his company building a new hydroelectric dam along the river, proudly telling him that he was Springfield's "Chief Hydrological and Hydrodynamical Engineer". Cecil's true intentions, however, were to skim money from the dam project's contract, build a poor quality dam, and frame his brother for the resulting destruction (mainly due to his still being sore about Sideshow Bob getting the part of sideshow on Krusty's show). Cecil's plot was discovered by Bart and Lisa Simpson, although they initially thought it was Sideshow Bob who was guilty until Cecil revealed his true colors. Ultimately, he lost the laundered money in a struggle against Bart. However, he does try to succeed in doing "the one thing Bob failed to do," which is of course killing Bart Simpson, albeit in an ironically crude fashion as him throwing Bart off of a cliff, although he hints that he'll lie if anyone asks how he did it. This attempt was foiled, ironically by Sideshow Bob. Cecil wasn't done yet, however, so he decided to both blow up the dam as well as directly kill both Bart and Sideshow Bob by shooting the dynamite stick (Bob had to use the Dynamite as a rope to catch Bart), although Bob and Bart foiled this effort by cutting the detonation charge, nearly killing themselves in the process. Despite Bob's innocence, both brothers were sent to prison, since Chief Wiggum did not believe that Sideshow Bob was innocent, despite testimonies from Bart, Lisa, himself, and Lou.[2]

Prison and Release Edit

Unpopular compared to his brother, and being compared to by a new prisoner as like Tito Jackson, Cecil was also forgotten by the police force for a parole hearing as he was apparently never checked into prison as Bob was also arrested at the same time, so Cecil was released, and he rented a hideout. Meanwhile Lisa Simpson was also being overshadowed by her brother. Wanting to surpass Bob's popularity, Cecil initially decided to kill Bart for thwarting his plot in destroying the dam, but he found killing Bart to cliched, after all those many times Bob tried it out, so he decided to kill Lisa instead, sending her a death threat. Marge, thinking that the threat was from Sideshow Bob, called the jail, only to find out that he was still there, his parole hearing having failed.

Meanwhile, Cecil managed to get a seat on the school board and, as part of a money saving plan, got Lisa's favorite lesson, music, canceled and her saxophone marked as a "dangerous instrument". He also joined the Friends of the Library Committee and got the library's books replaced with graphic novels. He also threatened Krusty with pictures from his Bangkok vacation, so he would stop showing Itchy and Scratchy, which was replaced with Jeeves and Wooster and gets her school permanently closed. Comparing the death threats, Lisa notices the different, yet similar handwriting, just as a wrecking ball smashed through the wall. Gary, Doug and Benjamin trace the IP for Lisa and Bart, which leads them to the Warehouse District. However, Cecil was already there and caught them, as the nerds were working with Cecil. However, the wrecking ball was from the Construction Workers Union, as Homer ate their lunch. Cecil planned to freeze Bart and Lisa in liquid nitrogen, like he had some door-to-door salesman. At that moment however, the police arrived and arrested Cecil, who became distraught at his failure. When they both realized that they were sharing the same problem of being seconded by their older siblings, Lisa and Cecil shared a gentle hug before the police, shocked by the surprising outcome, took the latter away.

Bob's Funeral Edit


Cecil at Bob's "funeral"

He was seen again when Sideshow Bob was put on trial for trying to kill The Simpsons family and there his father says Sideshow Bob has a rare heart condition which was caused by his many failed attempts to kill Bart.[3] It was then revealed he had to take medication to keep himself healthy but Bart throws it out the window thinking it's a bomb and Sideshow Bob drops dead. But, Cecil then invites Bart to Bob's cremation and Bart decides to go to change the way he acted during Bob's funeral, however it is just a trap and Sideshow Bob is not dead but is alive and came out of his coffin to kill Bart by putting him in it and getting burned. But Bob's family's plan is yet foiled again and Bob, Cecil, Robert Sr., Francesca, Gino and Dame Judith are all sent to jail, while Bob is stuck in a straitjacket, and most of his family is playing poker. In "The Bob Next Door", it is unknown why he and the rest of Bob's family were not seen in Bob's cell.

Bart's Dream Edit

Cecil made a brief appearance in one of Bart's dreams, in which he and Bob are flying kites together.[4]

Behind the Laughter Edit

Cecil, voiced by David Hyde Pierce, and Robert, voiced by Kelsey Grammer, have a relationship similar to that of Niles Crane and Frasier Crane, whom the actors played on the sitcom Frasier. His mannerisms are similar to that of his Frasier counterpart. Cecil was designed to look similar to David, yet still look like Sideshow Bob. Also, at the dam, when Bart is hanging on to Cecil's back and covering his eyes, Bart says "Guess who?" Cecil answers "Maris?" Maris Crane is Niles' erstwhile wife on Frasier.
