Springfield Elementary signs a deal with a snack company to install vending machines in the schools—with Bart taking advantage of the situation to the point that he becomes obese and suffers a heart attack.

!!Tropes:

* BitingTheHandHumor: Towards the end:
-->'''Bart:''' I've learned that even made-up corporate mascots can lie to you.
-->'''Homer:''' (''holding up stuffed animal'') Did you hear that Foxie, the Fox Network fox?
* DrillSergeantNasty: Tab. One fat camp exercise is making the patients pull him on a chariot while he whips them.
-->'''Bart:''' This can't be legal!
-->'''Tab:''' It's legal enough! (''cracks whip'')
* GratuitousGerman: Homer sings "99 Lüftballons" (in the original German, not the English translation) by Music/{{Nena}}.
* LastSecondWordSwap: When the family stages an intervention for Bart, Bart says "What the f-amily!"
* MythologyGag: When Bart is having a heart attack, Homer tells him to "Do the Bartman".
* OpeningShoutOut: In one scene, a variation of the opening sequence is played, only it lasts much longer now that Bart had become slower because of his extra weight.
* PreMortemOneLiner: Parodied when [[TheAhnold Rainier Wolfcastle]] throws some ice cream away as an exercise at the fat camp.
-->'''Rainier:''' Here's the scoop: Your Haagen Dazs (hoggin' days) are over! (''throws scoop into trash'')
* RuleOfDrama: Lampshaded and PlayedForLaughs as Tab Spangler takes Bart home to show the sacrifices his family is making.
-->'''Tab:''' Young man, there's something I have to show you. In one hour. We have to drive there. No talking along the way, it'll hurt the drama.
-->(''later, while driving'')
-->'''Bart:''' Can I just...
-->'''Tab:''' Shh, ''drama''!
* ShoutOut:
** When Tab takes Bart home to show the youth hostel it became, Bart asks if the guests can see them and the coach says that they obviously can since he's not [[Literature/AChristmasCarol the Ghost of Christmas Past]].
** One excuse Bart gives about his obesity is being [[WesternAnimation/SouthPark "Big boned."]] Unsurprisingly, Tab refuses to accept that.
* StagingAnIntervention: The Simpsons do this to convince Bart to lose some weight. When he tries to make a break for it, he is taken by "professional child snatchers" to the fat camp.
* TemporaryBulkChange: Bart becomes obese after eating too many snacks.
