While Lisa implements a recycling program, Mr. Burns discovers that he's lost his fortune (and was never told this beforehand because his accountants are sycophants/afraid of Mr. Burns' wrath) and now must live like a common man. With Lisa's help, Mr. Burns devises a [[ThePlan plan]] to regain his fortune.
!!This episode contains examples of:
* AsHimself: Wrestling/BretHart.
* BaitAndSwitch: This line, from Skinner:
--> '''Skinner''': What a load of garbage... I'm ecstatic!
* BeyondTheImpossible: After Lisa turned down Burns' offer, Homer experienced ''four'' simultaneous heart attacks (and a fifth one after Lisa tells Homer that 10% of $120,000,000 isn't $12,000[[note]]it's $12 million for those of you playing at home.[[/note]])
* CallBack: When Lisa and Mr. Burns were arguing about recycling and it went to how wealthy Burns was, Lisa produced a copy of the biography Burns wrote ("Will There Ever Be a Rainbow?") from the season two episode [[Recap/TheSimpsonsS2E22BloodFeud "Blood Feud"]], where Homer forces Bart to donate blood to save Mr. Burns' life under the impression that they will be given money.
** Also Burns knows it was [[Recap/TheSimpsonsWhoShotMrBurns Maggie who shot him]] but still doesn't know [[RunningGag Homer's name]]
-->'''Kent Brockman:''' Remember millionaire C. Montgomery Burns? The man who [[Recap/TheSimpsonsWhoShotMrBurns blocked out our sun]], [[Recap/TheSimpsonsS2E10BartGetsHitByACar ran over a local boy]], and [[NoodleIncident stole Christmas from 1981 to 1985]]? Well, guess who's flat broke, and picking up trash for a living?
-->'''Homer:''' Please be Flanders, please be Flanders...
** Also, when Lisa showed herself disgusted at knowing what the slurry named after her was made of, Mr. Burns thought a spoonful of it would have made her better. Sure, he didn't understand why Lisa didn't like the idea but he should have noticed she didn't.
* DistantReactionShot: When Homer ends up in the hospital after Lisa turned down Burns' offer, he bemoans the loss of what he ''thinks'' is $12,000. Lisa then began to reluctantly clarify to him how much she actually gave up[[note]]$12,000,000[[/note]]; cut to the hallway with an alarm going off about a 'Code Blue'[[note]]a heart attack[[/note]].
* EvilCannotComprehendGood / HeroWithAnFInGood: Mr. Burns has genuinely found a desire to do good, but he doesn't realize how wrong it is that Lil' Lisa's slurry is made from live sea creatures.
-->'''Lisa:''' You're ''still'' evil, and when you try to be good, you're ''even more'' evil!
* GoneHorriblyRight: Lisa teaches Burns to recycle. And boy, does he...
* GrandFinale: In the DVD commentary, the writers and producers joke that they could have ended the series with this episode, since the ending implied that Homer died of a massive heart attack.
* HonestAdvisor: Burns recruits Lisa since an honest voice can help him more than the yes men who bankrupted him.
* InvisibleSubtleDifference: When Marge tries to recycle, she gets it wrong:
--> '''Lisa''': Mom, Mom! You're mixing polyethylene with polyurethane.\\
'''Homer''': ''(aghast)'' Marge!
* MusicalGag: The ''Series/ThatGirl'' sequence ends with the Simpson doorbell ringing the last two notes of the melody.
* MyGodWhatHaveIDone: Lisa upon realizing what Lil's Lisa's slurry is made of.
* NoodleIncident: It's implied that Lenny, who was Mr. Burns' replacement at the plant, [[MeetTheNewBoss was every bit as ruthless as his predecessor, if not more so]]. When Smithers visits the Simpson house with Burns, he is surprised to see Homer at home:
-->'''Smithers:''' Simpson! What are you doing here? Shouldn't you be at work?
-->'''Homer:''' I made a mistake and Lenny sent me home to think about what I'd done, but I can't remember what I did, so I'm watching TV.
-->'''Smithers:''' Well, Lenny's reign of terror is over. [[FalseReassurance Mr. Burns bought back the plant this morning]].
* RichesToRags: Mr. Burns thanks to listening to spineless Yes-men. [[RagsToRiches Lisa helped him to become wealthy again]].
* ScrewTheMoneyIHaveRules: Lisa refuses to accept her share of the profits from Mr. Burns' sale of the Lil' Lisa's slurry factory. [[FlameBait Many fans have argued whether this was wise of her or not]].
* ShoutOut: The sequence when Mr. Burns tries to ask Lisa to help him spoofs the TitleSequence of ''Series/ThatGirl''.
** The scene where a confused Mr. Burns goes to a grocery store is inspired by an apocryphal account of UsefulNotes/GeorgeHWBush being amazed at a grocery scanner.
** The recycling center is called "Uriah's Heap", named after the character Uriah Heep from ''Literature/DavidCopperfield''. The hippie who owns the center is modeled after Dennis Hopper's photographer character from ''Film/ApocalypseNow''.
** The scene where Lisa runs down the streets of Springfield, trying to stop everyone from using Lil' Lisa's slurry spoofs ''Film/InvasionOfTheBodySnatchers'' and ''Film/SoylentGreen''.
-->'''Homer''': Well Lisa, I hope you learned your lesson. "Never help anyone".
* StrawNihilist: Bart, on recycling:
--> '''Bart''': ''(to Lisa)'' Ah, recycling is useless, Lise. Once the sun burns out, this planet is doomed. You're just making sure we spend our last days using [[TakeThat inferior products.]]
* UndyingLoyalty: Smithers continues caring for Burns even upon his bankruptcy. He even lets him live in his house.
* YourAnswerToEverything: Smithers says he didn't warn Mr. Burns about the Great Depression because he still wasn't born back then. Mr. Burns says it's Smithers' excuse for everything.
