After Mr. Burns gets busted by the Environmental Protection Agency and ordered by the court to pay $3,000,000 in fines, the city holds a meeting to discuss what can be done with the money[[note]]Lisa wants the school to have it so they can get better equipment and supplies for learning, Bart wants it so he can build mechanical ants that bisect Principal Skinner and destroy the school, Marge wants the money to go to fixing Main Street's potholes and cracked roads caused by Homer and other drivers, Homer wants a giant billboard that says, "No Fat Chicks," Maude wants more firefighters so that blaze on the east side of town can be extinguished, Apu wants more police officers so he won't get shot and miss work, and Mr. Burns -- under the unconvincing name of Mr. Snrub -- wants the money to go back to the nuclear plant[[/note]] -- and a smooth-talking salesman named Lyle Lanley convinces the town (through song and dance) to build a monorail. But while everyone is won over, Marge suspects that Mr. Lanley's project may cause problems...especially when he hires Homer as the monorail conductor.
!!This episode contains examples of (YMMV tropes can be found [[YMMV/TheSimpsonsS4E12MargeVsTheMonorail here]]):
* AsHimself: Creator/LeonardNimoy
* AdamWesting: Leonard Nimoy as a weird, has-been celebrity who bores people with his stories about being on the original 1960s ''StarTrek'' and has teleportation powers.
* AlliterativeName: Lyle Lanley.
* ArsonMurderAndJaywalking: Lanley's cost cutting measures on the North Haverbrook monorail:
-->'''Cobb''': He cut corners everywhere: bad wiring, faulty brakes, and the celebrity on the maiden voyage was ''Gallagher''.
* BigNo / LittleNo: A rare example of these tropes being used in unison, when Lyle Lanley learns his non-stop flight to Tahiti is about to make an unscheduled stop over in North Haverbrook:
-->'''Lyle Lanley:''' "North Haverbrook"? Now where have I heard that name before? ''[Realizes]'' [[LittleNo Oh no.]] [[BigNo OH NO!]]
* ButNowIMustGo: Parodied, after the monorail crisis is resolved:
-->'''Leonard Nimoy:''' Well, my work here is done.
-->'''Barney:''' Whaddaya mean? ''You'' didn't do nothing.
-->'''Leonard Nimoy:''' [''Chuckles knowingly.''] Didn't I? [''[[Series/StarTrekTheOriginalSeries beams away]].'']
* CaptainErsatz: Lyle Lanley is one of Harold Hill, the protagonist of ''TheMusicMan''.
* ConvenientEclipse: "The cosmic ballet...goes on." Too bad it only lasts a couple of minutes.
* CrowdSong: "The Monorail Song".
* CrouchingMoronHiddenBadass: Homer saving the monorail passengers by creating an anchor with a giant advertisement donut ("is there anything they can't do"), making him the best mono-thingy guy there ever was.
* CutTheJuice: Two guys discuss the out-of-control monorail:
-->'''Guy 1:''' I got it! We can just shut off the power!\\
'''Guy 2:''' No such luck. It's solar-powered.\\
'''Guy 1:''' Solar power. When will people learn!?
* DawsonCasting: [Invoked] Spoofed with the star of ''Springfield Heights 90210'', Kyle Darren, who Kent Brockman mentions is actually 35 years old. He then displays his extremely wrinkly smile.
* DescriptionCut: When Cobb says that he hopes the monorail has a good conductor, it cuts to Homer trying to open the monorail door with a wire hanger.
* EyeBeams: A squirrel mutated by the toxic waste stored in its tree has these.
* AFateWorseThanDeath: What's implied to happen to Lanley when his plane lands in North Haverbrook. Many of the survivors of the town rush the airplane and immediately confront Lanley; the plane rocking and shaking violently, and his squealing in pain, suggests that he is being severely beaten.
* FauxAffablyEvil: Lyle Lanley, being a conman and all.
* GhostTown: After she becomes suspicious of Lyle Lanley, Marge goes to North Haverbrook, the town he sold a monorail to before Springfield. She finds the town nearly deserted after their monorail crashed on its maiden voyage.
* {{Homage}}: The opening scenes have Homer, who's just getting off of work, doing his own version of the opening credits and theme song from ''TheFlintstones''.
--> ''Simpson, Homer Simpson!\\
He's the greatest guy in history!\\
From the town of Springfield\\
[[WatchOutForThatTree He's about to hit a chestnut tree!]]'' Aaaah! (crash)
* ILoveNuclearPower: Mr. Burns stores nine drums of nuclear waste in a single tree, causing some of the tree's branches to turn into purple tentacles and a squirrel inhabiting it to gain EyeBeams and a long prehensile tongue, both of which it uses to its ecological advantage.
* IdiotBall: Virtually the entire town, as typical for Springfield, who fall hook, line and sinker for Lanley's pitch for a monorail – which is why he is easily able to get away with his scheme to sell what turns out to be shoddy and ultimately worthless; note they make an agreement with virtually no specifics given about the monorail or its benefits. Also helping Lanley's case: He implies that arch-rival town Shelbyville is strongly considering buying one of his monorails -- perhaps not mentioning (indeed, it never comes up) that he was likely kicked out of a Shelbyville meeting when he had gone there previously to make his sales pitch and warned never to return.
** Also, Lanley himself when he finds Marge in his office snooping around his paperwork … instead of detaining her (because he would now realize she knows he's a shyster and a fraud, and keeping her silent would have allowed him to continue with his fraud), he lets her leave, though she doesn't actually find out what he's planning until she decides to investigate one of the cities he claimed to sell a monorail too.
** Add to that, the discriminating evidence Marge found was sadistic doodles of him laughing at the "suckers" he conned meeting their deaths in his shoddy monorail. He left this rather clear and evident VillainBall just lying around in his office.
* IgnoredEpiphany: After the near miss with the monorail, the town makes it the last folly they made...except for the popsicle-stick skyscraper ... and the giant magnifying glass ... and the escalator to nowhere.
* KarmaHoudini: Burns got away with poisoning children and damaging Springfield's environment by storing nuclear waste in parks and playgrounds. Yeah, he paid a 3 million dollar fine, but that's chicken feed for the billionaire.
** Subverted with Lyle Lanley. He ''almost'' gets away with defrauding Springfield, but ends up getting beaten up by the people of North Haverbrook.
* LaserGuidedKarma: Lanley got one when the plane he was in landed in North Haverbrook. A TorchesAndPitchforks crowd storms the plane and it's implied that they lynch him.
* MeatOVision: Homer is trapped on the out-of-control monorail train and needs to find an anchor. He looks to Bart, and visualizes him as a large ship's anchor. Bart, for understandable reasons, urges him to ''think harder''.
* NoHoldsBarredBeatdown: [[GoryDiscretionShot Heavily implied]] with Lanley after his plane lands in a town he previously conned.
* NoodleIncident: Chief Wiggum has pictures of Mayor Quimby in a compromising position that involves his ass.
** When did the town build the Popsicle stick skyscraper, the 50 ft. magnifying glass, and the escalator to nowhere?
* OhCrap: Lyle Lanley when it was announced he'd have to land in North Haverbrook.
* [[OnlySaneMan Only Sane Woman]]: Marge is the only person in town not drawn in by monorail fever. As such, she is able to uncover the true danger of the monorail.
* SdrawkcabAlias: Mr. Burns attempts to get his money back by disguising himself with a [[PaperThinDisguise fake mustache]] at the town meeting and calling himself "Mr. Snrub". Not surprisingly, it fails instantly.
* SelfDeprecation: Leonard Nimoy, voicing himself, is portrayed as self-important, annoying, and still clinging to his memories of being Mr. Spock on the original ''Star Trek''.
-->'''Leonard Nimoy:''' (After Mayor Quimby uses a ''StarWars'' reference to introduce him) Do you even know who I am?!?
-->'''Mayor Quimby:''' Er,ah I think so....weren't you one of ''TheLittleRascals''?
* ShippedInShackles: C. Montgomery Burns is given the Hannibal Lecter mask treatment when he is dragged into court.
* ShoutOut:
** Al Jean amusingly notes in the commentary that the engineer was modeled after Creator/MaxVonSydow, as he once played a man trying in vain to warn a town of an impending disaster...except Jean now can't recall what the movie was called, or even what the disaster was.
** "The Music Man" – Parts of the episode are a tribute to the classic musical, with Lanley patterned after the play's Professor Harold Hill and "The Monorail Song" a spoof of "Trouble."
** ''Film/TheToweringInferno'': Not usually thought of, but the connection is there – a shoddily built skyscraper with the developer making extreme cuts to save money vs. Lanley's discount-model monorail, which is also poorly built thanks to his deep cost-cutting measures. In both cases, thousands of lives are put at risk as disaster strikes (a massive fire that is growing vs. an out-of-control monorail that, if it were to have crashed, would have surely killed many people and caused catastrophic damage).
** The "escalator to nowhere" is a parody of numerous "bridges to nowhere", where government money is spent on constructing unnecessary bridges, usually with accusations that the company building the bridge is in cahoots or most of the money is being funneled to elsewhere. The escalator tops these by literally ending in the sky.
* TheSociopath: Lanley crosses the line from just apathetically conning people with a dangerous monorail to cruelly gloating about their demise, expressing so through childlike doodles.
* SolarPoweredMagnifyingGlass: Marge's closing narration: "And that was the only folly the people of Springfield ever embarked upon... Except for the Popsicle stick skyscraper. And the 50-foot magnifying glass [''the sun focused through the magnifying glass sets the Popsicle stick skyscraper on fire'']. And that escalator to nowhere."
* SomebodyElsesProblem: At the beginning of the episode, Lenny and Carl wonder where the barrels of toxic waste are going, before deciding they don't care.
* SpecialGuest: Creator/PhilHartman as Lyle Lanley
* SustainedMisunderstanding:
-->'''Marge:''' Homer, there's a man here who thinks he can help you!
-->'''Homer:''' Batman?!
-->'''Marge:''' No, he's a scientist.
-->'''Homer:''' Batman's a scientist!?
-->'''Marge:''' It's not Batman!
* TorchesAndPitchforks: North Haverbrook has an angry mob ready and eager to take down Lyle at the end.
* TooDumbToLive: Even though the escalator to nowhere ends in a long fall, citizens of Springfield still take it, presumably falling to their deaths.
* TotalEclipseOfThePlot: The runaway monorail, which is solar-powered, halts briefly due to a total solar eclipse which nobody realized/remembered was due in Springfield that day — only to start up again as the eclipse passes totality. [[TruthInTelevision This is realistically portrayed as taking under a minute]] (real-life solar eclipses can last any time from an eyeblink to, under the most favorable circumstances, about 7-8 minutes).
* VersusTitle: One of many for ''TheSimpsons''. Others include "The City of New York vs. Homer Simpson," "Bart vs. Thanksgiving," "Homer vs. Patty and Selma," "Lisa vs. Malibu Stacy," etc.
* WouldHurtAChild: Mr. Burns had been storing his barrels of toxic waste in a playground. He only changes the location when he decides all the bald children might make someone suspicious.
* YouAreTooLate: Marge and Mr. Cobb arrive as soon as the monorail starts:
-->'''Marge:''' We're too late!
-->'''Cobb:''' I should not have stopped to get that haircut. Sorry.
