------------------------------------------
!!This episode contains examples of: ([[YMMV/TheSimpsonsS13E8SweetsAndSourMarge YMMV Examples here]])
* BitingTheHandHumor: While burning most of the sugary sweets and food products in town, the police throw a pile of Butterfingers into the flames. The fire rejects the Butterfingers, causing Chief Wiggum to comment that the fire "doesn't even want them". This gag cost the Simpsons their contract with Butterfingers and has been cut from all American reruns (including syndication)[[note]]most international versions, such as the Brazilian dub, have the scene uncut[[/note]], though the season 13 DVD box set version has the scene intact and Butterfingers' contract with the Simpsons franchise has been renewed in 2013.
* CaptainErsatz: Count Fudgula, an obvious parody of Count Chocula
* CorruptCorporateExecutive: The very concept of corporate ethics is completely alien to Garth Motherloving.
* DoesThisRemindYouOfAnything: The entire episode plays with the idea of sugar being equatable to a drug, especially during the scene where Homer, Mr. Burns, Apu, and Count Fudgula smuggle sugar into Springfield. The scene that best hammers this in is when Disco Stu sucks up lines of sugar through a straw in a manner akin to snorting cocaine (which is funny, considering a recent report that states that sugar addiction is similar to cocaine addiction).
* DrivenToSuicide: An anonymous Springfield resident leaps off a building to commit suicide, [[SubvertedTrope only to land in the people ball that forms from Homer's people pyramid]].
--> '''Guy''': GoodbyeCruelWorld. [He lands in the pile.] [[LampshadeHanging Hello ironic twist!]]
* FatAndProud: Most of Springfield is overjoyed when they're announced the world's fattest town. Only Marge is concerned that they're celebrating obesity.
* FateWorseThanDeath: Lisa doesn't initially believe that getting sugar back is worth Homer and Bart risking their lives. Until Marge announces she steamed limes for dessert, and Lisa shoves them out the door.
* JerkAss: [[IronicName Garth Motherloving is a total jerk]]
** FridgeBrilliance: "Motherloving" sounds like a {{bowdlerized}} take on "motherfucking," making him as bad as his name implies.
* InMemoriam: This episode was dedicated to Ron Taylor, the voice of Lisa's saxophone mentor and friend, Bleeding Gums Murphy (whose character died before his actual voice actor did).
* NotInMyContract: Homer said that and fled when the sugar-smugglers tried to collect payment. Their leader then read the contract and realized Homer was right.
* ReversePsychology: Homer tries this on a seagull that steals his map to the sugar rendezvous point. It fails.
* RuleOfThree: Readied in his diving gear, Homer falls backwards off the top of Burns' yacht, landing on the lower deck. He tries again, landing on the flat surface of a nearby whale. He quips [[LampshadeHanging "I'm only gonna do this one more time"]] before managing to land in the water.
* SarcasmMode: Garth Motherloving "agreeing" to Marge's suggestions.
* ShoutOut: Homer refers to Marge throughout the second half of the episode as variations of ErinBrockovich (such as "Erin Chocosnitch").
** One of the sweets burned in the fire is a promotional chocolate statuette of JohnnyDepp from ''Film/{{Chocolat}}''.
** Garth Motherloving bribes Homer into helping his plot by showing him a smoking [[Literature/CharlieAndTheChocolateFactory Oompa-Loompa]].
* SuicideAsComedy: See DrivenToSuicide.
* UnfortunateNames: Garth Motherloving previously went by the surname [[AdolfHitler Hitler]].
