The Comic Book Guy is forced to take a sabbatical from working at the Android Dungeon after suffering a heart attack during a Creator/TomSavini Q&A session, and reluctantly lets Bart and Milhouse (whom he banned earlier in the episode) run the store.

!! Tropes:
* {{Bowdlerization}}: Ralph's line when he originally walked into the "Adult" section of the comic book store was "She's hungry!", but the censors rejected it and it was replaced with "Everybody's hugging!"
* BlindWithoutEm: Milhouse takes off his glasses to fight, and immediately puts them back on.
* FreezeFrameBonus: The pictures on the "Banned for Life" wall are of Nelson, Sideshow Bob, and Matt Groening (though some viewers mistook the Groening caricature for George Lucas).
* GrailInTheGarbage: What makes the Guy ban Bart and Milhouse is the fact that Martin's mom arrives with some memorabilia that Martin collected to sell... which includes such things as a handwritten alternate script of ''TheEmpireStrikesBack'' where ''Chewbacca'' is [[LukeIAmYourFather Luke's father]], anti-jiggle breast tape Carrie Fisher had to wear when playing Princess Leia, and the like, the Guy then tries to swindle Martin's mom to sell all of it for five dollars (after having a fangasm) and Bart and Milhouse tell Martin's mom that it's priceless stuff (and she says "back to the leaky basement they go!" in response).
* GrievousBottleyHarm: Lenny attempts this on Comic Book Guy when the latter calls beer the nectar of the nitwit. [[EpicFail The entire bottle shatters in his hands]].
* HollywoodHeartAttack: What happens when Comic Book Guy's RageBreakingPoint is reached re: Bart and Milhouse's attempts to enter the store. As befits his character, [[LargeHam he describes the symptoms of his attack in a fashion resembling old-school comic book narration]].
* HypocriticalHumor: This exchange occurs when Comic Book Guy turns down beer:
-->'''Comic Book Guy:''' I'll pass! Beer is the nectar of the nitwit.
-->'''Carl:''' Hey, are you [[BerserkButton knocking beer]]?
-->'''Lenny:''' Nobody badmouths Duff!
-->(''Lenny smashes a bottle, attempting to [[GrievousBottleyHarm stab Comic Book Guy with it]], but the entire bottle shatters in his hands.'')
-->'''Lenny:''' Aw, piece of crap!
* MayDecemberRomance: Comic Book Guy with Agnes Skinner.
* NerdsSpeakKlingon: After he gets thrown out of Moes, Comic Book Guy ask himself "Is there a word in Klingon for loneliness?", looks in his pocket dictionary. "oh, yes. [[SkywardScream Garr'dock!]]".[[note]]Not actually an official Okrandian Klingon word.[[/note]]
* SinisterSurveillance: The Comic Book Guy's video vault contains a number of secret videos, including surveillance footage from all over town and such things as ''real'' alien autopsies.
* ShoutOut: Biclops is a nerdy version of Franchise/XMen character Cyclops. A potential customer (Kearney the bully) asks if Biclops has a girlfriend named [[ComicBook/LoisLane Lois Lame]].
* TakeThat: In the original script and closed captioning, Bart orders Milhouse to mark down the ''SouthPark'' merchandise until someone actually buys it (in the actual episode, Bart tells Milhouse to put the Poochie merchandise on clearance and throw in some ''Super Girl'' comics).
** Biclops is also a take on the absurdly lame characters [[MerchandiseDriven created to try to provide advertisement on stuff like toothpaste and fast food]].
** When Bart and Milhouse find The Comic Book Guy's illegal video vault, one of the videos in the collection is "''Godfather III'': The Good Version."
* UngratefulBastard: Comic Book Guy to Bart and Milhouse for saving his life. Though he does cave in and allow them to run the store.
