Sideshow Bob is released from prison again for good behavior and put into the custody of his brother, Cecil, but Bart and Lisa still think Bob is out to kill them -- until they learn that Cecil is just as evil as Bob.
!!This episode contains examples of:
* AllGirlsWantBadBoys: Krabappel has dinner with Bob for the excitement of dating a killer, and is visibly disappointed when he admits he's never successfully killed anyone.
--> "I did once try to kill the world's greatest lover - but then I realized there are laws against suicide."
* BittersweetEnding: Cecil's plot is exposed and he's carted off to prison for it. But Bob's HeelFaceTurn is rejected and he's sent back as well, despite being innocent and saving Lisa and Bart, and is doomed to revert to his evil ways. Oh, and the dam breaks, flooding Springfield.
* BriefcaseFullOfMoney: Cecil has one. Or had one.
-->'''Cecil:''' ''"Ahhh...shhh[[LastSecondWordSwap oot!]]
* ConstructionCatCalls: Discussed when Bob asks if his job will be leading the hooting. "Oh yeah, shake it, madam! Capital knockers."
* DescriptionCut: "Sideshow Bob is an unstoppable killing machine!" Cut to Bob singing Amazing Grace at the prison chapel.
* EnemyMine: The first time Sideshow Bob had to team up with the Simpsons to foil a common enemy.
* [[EspeciallyZoidberg Especially Lisa]]: "But especially Bart."
* {{Foreshadowing}}: Some people may find it odd how Cecil later teams up with Bob to kill Bart in Funeral for a Fiend, but the finishing line here is Cecil calmly asking when they will bring the menus after the WimpFight they just had. Given that that episode came out ''eleven years'' later, it's quite likely that all that time in jail has given them time to sort out their differences. After all, since they're essentially an evil [[Series/{{Frasier}} Frasier and Niles Crane]], it's a pretty safe bet that they will have much to talk about together.
* HeroicBSOD: Lisa is left defeated the moment Cecil turns on them. Bob, who she has defiantly outsmarted each and every time, goes into an offended rant over this.
* {{Irony}}: Cecil needed a ride to Krustylu Studios for the Sideshow auditions and that was Bob's only motive to be there. Bob got the job coveted by Cecil because Krusty decided to use him to show that the PieInTheFace gag is "only funny when the saps got dignity."
* LongLostUncleAesop: Sideshow Bob and Cecil never spoke to each other for ten years.
* GroinAttack: A fall from the top of a dam long enough to require you to take another breath to continue screaming, and landing crotch first onto a water outlet pipe. Bob doesn't say anything, but he's shocked so rigid that his legs don't let go of the pipe when he slips below it.
* MilitaryMoonshiner: After prison, Bob will be happy with any wine that ''doesn't'' taste like orange drink fermented under a radiator. "[[TakeThat That would be the Latour, then...]]"
* NoLongerWithUs: "Madam, your children are no more - than a pair of ill-bred troublemakers."
-->'''Homer:''' Lisa too?
-->'''Bob:''' Especially Lisa! But especially Bart.
* NonIronicClown: "Sideshow Cecil", who bombs his audition.
* NoNonsenseNemesis: Throwing someone off a dam ''is'' a little crude for a genius like Cecil...Eh. If anyone asks, he'll lie.
* NotMeThisTime: Sideshow Bob isn't the villain this time, Cecil is and he's trying to frame Bob.
* OffOnATechnicality: The reason Krusty is only ''playing'' at Springfield Prison.
* PieInTheFace: According to Krusty, it's "only funny when the sap's got dignity."
* PrayerOfMalice: Bart asks God to kill Sideshow Bob. "It's him or me, O Lord!"
-->'''Marge:''' You can't ask God to kill someone!
-->'''Homer:''' Yeah, you do your own dirty work!
* RedHerring: After getting annoyed at the stupidity of the dam's construction workers, Sideshow Bob mutters angrily, "Sometimes I wish this dam would burst, and bury this cursed town." Of course, as we later discover, this is [[IneffectualDeathThreat just Bob blowing off some steam]]; unlike in previous episodes, he doesn't actually have an evil plan in mind.
* ReformedButRejected: Big time. Bob has truly reformed and the Simpsons kids totally believe him after all they've been through...but he's still taken to jail. Ouchies!
* SarcasmMode: "Goodness, I had no idea. For, you see, I have been on Mars for the last decade, in a cave, with my eyes shut and my fingers in my ears."
* SiblingRivalry: An even more intense one between Bob and Cecil than between Bart and Lisa, if that's possible.
* StatusQuoIsGod: Wiggum seems driven to send Bob back to jail just to enforce this.
* TakeThat: To Bordeaux and Château Rauzan-Ségla wines:
--> '''Cecil''': Perhaps a glass of Bordeaux? I have the '82 Chateau Latour and a rather indifferent Rauzan-Ségla.\\
'''Bob''': I've been in prison, Cecil. I'll be happy just as long as it doesn't taste like orange drink fermented under a radiator.\\
'''Cecil''': That would be the Latour then.
* VillainByProxyFallacy: Wiggum throws Bob in prison on general principle (despite two kids he's repeatedly tried to kill vouching for his innocence).
* VillainsOutShopping: Bob's first thought on being released: "I hope they still make that shampoo I like."
* WickedCultured: Bob and Cecil both qualify.
* WimpFight: Over who gets the top bunk in prison.
* WireDilemma: Bob cuts the wires on a bundle of dynamite. Lisa questions if he knows what he's doing, leading to Creator/KelseyGrammer's favourite line.
--> ''Well, Lisa, you don't spend ten years as a homicidal maniac without learning a thing or two about dynamite.
