Episode - 9F15\\
First Aired - 3/11/1993

Lisa's visit to Painless Dentistry (formerly Painful Dentistry) results in her and Marge learning that she needs braces, lest she end up disfigured by her unchecked teeth -- though Bart is intrigued by the prospect of her becoming "a freak!" Meanwhile, Mr. Burns is trying to get the power plant's union off his back by giving them free beer in exchange for the plant employees' dental plan. Homer is about to go along with it, but then remembers Lisa is about to get braces. This causes him to make a {{Rousing Speech}} about the importance of the dental plan that gets him elected as the union president. While Lisa is forced to settle for BracesOfOrthodonticOverkill, Homer starts going toe to toe with Burns and ultimately leads the workers in a strike. When even an intentionally-caused blackout can't keep the workers down, Burns is forced to concede and Lisa gets proper, "invisible" braces.

Chosen by ''TV Guide'' as the show's best episode, it remains a favorite with fans due to its complex plot and multitudes of clever {{Shout Out}}s.
--------------------------
!!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!"
* 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, 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.
* 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.
* 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.
* {{Homage}}: Plenty, including:
** Hubert Selby Jr.'s novel ''Last Exit to Brooklyn''
** Jimmy Hoffa being buried at Giants Stadium
* 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.)''
* ImagineSpot: "[[MadLibsCatchPhrase Mmm... organized crime...]]"
* KillerRobot [=/=] SuperPoweredRobotMeterMaids: See AIIsACrapShoot, above.
* 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.
* 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 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 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 ''{{Citizen Kane}}''.
* 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.
* 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.
* TakeThat: One of the pictures in the "Big Book of British Smiles" shows [[BritishRoyalFamily Prince Charles]].
* TurnedAgainstTheirMasters: Burns's fantasy sequence.
* WhatCouldHaveBeen: The dentist was going to be voiced by Anthony Perkins (Norman Bates from ''Psycho''), who died before he could record his lines. AnthonyHopkins and Creator/ClintEastwood also turned down the role. And O. J. Simpson was originally going to be cast as a news panelist, but he turned it down and was replaced by Dr. Joyce Brothers. Given O.J.'s later murder trial, the writers were glad that he wasn't picked.
* 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.
