[[caption-width-right:350:[[MemeticMutation Dental Plan! Lisa Needs Braces!]]]]
Episode - 9F15\\
First Aired - 3/11/1993

In this episode, cited by ''Entertainment Weekly'' and several other critics as the series' magnum opus, Homer is unwittingly made the leader of the nuclear plant's labor union so he can fight back against Mr. Burns revoking the workers' dental plan, which Lisa needs for invisible braces.
!!This episode contains examples of (YMMV tropes can be found [[YMMV/TheSimpsonsS4E17LastExitToSpringfield here]]):
* AIIsACrapshoot: Burns's fantasy sequence of him and Smithers running the plant includes them opening crates marked "Robot Workers - [[BlatantLies 100% Loyal.]]" The scene switches to [[TurnedAgainstTheirMasters the robots chasing Burns and Smithers]], chanting "CrushKillDestroy!"
* AnachronismStew: When Mr. Burns shuts off all the power to the city, one shot of a street shows several people dressed like they're from the 1930s.
* ArsonMurderAndJaywalking:
-->'''Mr. Burns:''' ''(reading the union contract)'' Benefits? Perks? A green cookie on St. Patrick's Day?
** After giving Homer a tour of his estate, which includes the world's biggest TV, an aviary filled with vultures that look like him (at least one does), and [[MonkeysOnATypewriter 1000 monkeys on typewriters]], Mr. Burns finishes up inside his otherwise ordinary basement.
--->'''Mr. Burns:''' Yes, I should stop ending the tour with it.
* BigEntrance: In the [=McBain=] scene that opens the episode, [=McBain=] bursts out of an ice sculpture.
-->'''[=McBain=]:''' [[HilariousInHindsight Ice to]] [[Film/{{BatmanAndRobin}} see you]]!
* BritishTeeth: The dentist scares Ralph Wiggum into healthy dental habits by showing him a book called "The Big Book of British Smiles".
* TheCameo: Dr. Joyce Brothers appears in a single scene as the third member of Kent Brockman's discussion panel. Her only line of dialogue is, "I brought my own mic!" See WhatCouldHaveBeen below.
* CardCarryingVillain: The bad guy in the [=McBain=] movie ("To human misery!"). Homer reassures Bart there's [[TemptingFate no-one that evil in real life]].
* ComicallyCrossEyed: Principal Skinner tells a pupil to "put his eyes straight". When he answers: "But I can't", he realizes his mistake and says: "Oops, sorry Quigley!"
* ComicallyMissingThePoint: Homer, for several seconds, is unable to make a link between the proposed disappearance of the dental plan and Lisa's need for braces.
** Homer again during the scene mentioned in the InnocentInnuendo entry.
* ContinuityNod:
-->'''Mr. Burns:''' ''(watching Homer tear up the contract on a hidden camera)'' Who is that firebrand, Smithers?\\
'''Mr. Smithers:''' That's Homer Simpson.\\
'''Mr. Burns:''' Simpson, eh? New man?\\
'''Mr. Smithers:''' Actually, sir, [[Recap/TheSimpsonsS2E4TwoCarsInEveryGarageAndThreeEyesOnEveryFish he thwarted your campaign for governor]], [[Recap/TheSimpsonsS2E10BartGetsHitByACar you ran over his son]], [[Recap/TheSimpsonsS3E5HomerDefined he saved the plant from meltdown]], [[Recap/TheSimpsonsS2E18BrushWithGreatness his wife painted you in the nude]]...\\
'''Mr. Burns:''' Doesn't ring a bell.
** There is a slight ContinuitySnarl: Marge ruined Burns' run for governor, not Homer. Though Burns blames it all on Homer, and threaten to make his life dreams go unfulfilled until he forgets.
* CrapsackWorld: Springfield, exemplified when the power comes back on. Among the things we see lighting up again are the adult movie theatres, and the fake vomit factory.
* DepravedDentist: Doctor Wolfe isn't depraved, but he is unflinchingly strict, and torments Ralph with "The Big Book of British Smiles", which reduces poor Ralph to tears. He also knows when someone's lying.
* DescriptionCut:
** While watching the film at the beginning, Homer tells Bart no-one could be as evil as the villain from it. Cut to Mister Burns watching a window washer dangling from a wire and laughing.
** And this:
-->'''Homer:''' Guys are always patting my bald head for luck, pinching my belly to hear my girlish laugh.\\
'''Marge:''' Hmm, that doesn't sound like they like you at all.\\
'''Homer:''' You know, I think you're right. First thing tomorrow morning, I'm gonna punch Lenny in the back of the head!\\
''(The next morning, Homer punches Lenny in the back of the head.)''
* DoubleEntendre: See InnocentInnuendo. Homer announces that he's not interested in "backdoor shenanigans" as he's convinced that Burns [[MistakenForGay is coming on to him]]. Burns instead takes it as a sign that Homer is a tough negotiator.
-->'''Homer:''' Sorry, Mr. Burns, but I don't go in for these backdoor shenanigans. Sure, I'm flattered, maybe even a little curious, but the answer is no!
* EpicFail: After going through all those security doors, the underground control room has a door that leads outside, which was left open and a stray dog came in.
* EverybodyLaughsEnding: The family laughs in the dentist office in response to Lisa's lame pun (see below). Then it turns out they are laughing because the dentist left the laughing gas on.
* FailedASpotCheck: How did no-one notice the human-shaped lump on the football pitch?
* {{Homage}}: Plenty, including:
** Hubert Selby Jr.'s novel ''Last Exit to Brooklyn''
** Jimmy Hoffa being buried at Giants Stadium
* IdenticalGrandson: During the flashback to Mr. Burn's youth, one of the thugs who drags away the young thief is identical to one of the hired goons from later on.
* IncrediblyLamePun: "And that's the tooth!"
* InnocentInnuendo: Homer thought Mr. Burns was "coming on to him".
-->'''Mr. Burns:''' After all, negotiations make strange bedfellows. ''(winks with a chuckle)''\\
''(Homer screams in his mind.)''
** Later on, Mr. Burns watches Homer apparently exercising (he's not, he's trying to get a SugarDaddy off his back).
-->'''Mr. Burns:''' Look at him, strutting about like he's cock of the walk. Well, let me tell you, Homer Simpson is cock of ''nothing''!
-->'''Mr. Smithers:''' ''(who's caught the innuendo)'' Hrrm.
* ImagineSpot: "[[MadLibsCatchPhrase Mmm... organized crime...]]"
* KarmaHoudini: The small guy who never plays along with his coworkers and blames the muscular guy sitting next to him, who gets beat up by just about everyone else in the room, while the other one chuckles to himself.
* KickTheDog: A literal version when Burns and Smithers head towards the underground control room which gives Springfield its electricity, and find a stray puppy had wandered into the room. Burns sighs "Oh, for Heaven's sake!" kicks it out of the shack, and slams the door shut.
* KillerRobot [=/=] SuperPoweredRobotMeterMaids: See AIIsACrapShoot, above.
* TheLastTitle: The name of the episode.
* MushroomSamba: That's some heavy gas the dentist gives Lisa.
* NationalStereotypes: "The Big Book of British Smiles" pokes fun at the idea that British people have bad teeth.
* NoodleIncident:
** What exactly happened to the last union representative that wound up with him buried in a football field. It's implied later on that the workers know ''exactly'' what happened to him.
** Homer keeps asking Lenny to get his SugarDaddy off his back.
* OverlyLongGag: "Dental plan!" "Lisa needs braces!"
* TheParody
** Don Fanucci's first appearance in ''Film/TheGodfather Part II'' (Homer as a mob boss, taking bribes in the form of donuts);
** Lisa's surreal dream under narcosis is a parody of ''WesternAnimation/YellowSubmarine'', complete with an appearance by Music/TheBeatles.
** The scene where she checks her reflection in the mirror and laughs demonically is a parody of the Joker looking into a mirror after his facelift in Creator/TimBurton's ''Film/{{Batman}}''.
** The montage Burns and Smithers heading towards the power grid is a parody of ''Series/GetSmart''.
** Mr. Burns quotes Captain Ahab in ''Literature/MobyDick'' [[note]]or [[Film/StarTrekIITheWrathOfKhan Khan Noonien Singh]][[/note]] when he shuts down the power in Springfield.
** The scene where the power plant workers sing in a big circle, overheard by Mr. Burns, is a parody of ''WesternAnimation/HowTheGrinchStoleChristmas''.
** The closeup of a bird giving a Burns-like shudder references the infamous loudly-squawking parrot with a transparent eye from ''Film/CitizenKane''.
* OnOneCondition: Mr. Burns decides to give in to the union's demands and reinstates their dental plan privileges, but on the condition that Homer resigns as union president. Homer is ecstatic.
* ProsceniumReveal: The episode opens with a villain revealing a new drug and making a toast "to human misery!" Suddenly, [=McBain=] appears and kills the villain's accomplices, only to be gassed by salmon puff. During the EvilLaugh, it is revealed that Bart and Homer are watching a [=McBain=] movie.
-->'''Bart:''' That is one evil dude.\\
'''Homer:''' It's just a movie, son. There's nobody that evil in real life.
* ProtestSong: A parody of a 30s style union folk song, though the main refrain is good enough to pass for the real thing:
--> "So we'll march day and night\\
By the big cooling tower\\
They have the plant\\
But we have the power"
* RamblingOldManMonologue: Grandpa's favorite tactic in how to break up strikes is to tell stories that don't go anywhere. He then launches straight into the page quote.
* ReluctantRuler: Homer as president of the Springfield Power Plant Union. When Burns "pressures" him to resign to have the dental plan reinstated, he is overjoyed.
* SureLetsGoWithThat:
-->''[Homer runs into a long corridor and begins checking every room.]''\\
'''Homer:''' Nope... nope... nope...\\
''[Homer returns.]''\\
'''Mr. Burns:''' Find the bathroom alright?\\
'''Homer:''' Uh...yeah.
* TakeThat: One of the pictures in the "Big Book of British Smiles" shows [[UsefulNotes/TheBritishRoyalFamily Prince Charles]].
* ThereIsNoGod: The school photographer exclaims this when Lisa smiles for the camera as shown in the caption. For extra esteem-shattering points, he encouraged her not to be shy to smile because he assumed it'd be a beautiful one.
* TurnedAgainstTheirMasters: Burns's fantasy sequence.
* UncattyResemblance: One of the vultures in Burns's aviary looks like him. Even sounds like him.
* WorthyOpponent: Mr. Burns comes to regard Homer as this, as all of his attempts to buy or thwart Homer fail spectacularly. Of course, it's really all because Homer is TooDumbToFool.
-->'''Mr. Burns:''' Smithers, I'm beginning to think that Homer Simpson is not the brilliant tactician I thought he was.
