Lisa's A+++ grade she got on a test for the book, ''The Wind and the Willows'', gives Springfield Elementary the grant money it sorely needs to update the school. The problem: Lisa cheated on the exam after spending her sick days from school playing video games instead of studying. Meanwhile, Homer raises a lobster to eat, but makes it his pet.

!!Tropes:
* TheAllegedComputer: The Coleco computer that Gil is selling not only looks ''and'' acts like a computer that is incredibly old even by the time the episode first aired, but Gil unwillingly ends up mentioning that the computers of this brand rust up ''incredibly'' fast.
* AllAnimalsAreDogs: Pinchy the lobster.
* BaitAndSwitchComment: Superintendent Chalmers after Lisa threatens to report Principal Skinner to him for covering up the fact that she cheated.
-->'''Chalmers:''' Skinner!!! I am outraged that you kept this from me! You were supposed to call as soon as the new scoreboard was in. Tell me, does it play that song "charge"?
* BlackComedy: Homer weeping over the death of his beloved pet lobster... while eating him.
--> '''Homer''' (in between sobs): "It's so good! I wish Pinchy were here to enjoy it!"
* BrokenRecord: In Lisa's ImagineSpot, when she's told the only school which would accept her would be Brown University, Lisa says "No, not Brown, Brown, Brown...", repeating Brown, which leads Miss Hoover to ask "Lisa, you're saying 'Brown' an awful lot, are you okay?"
* CaptainErsatz: Dash Dingo is an obvious parody of Franchise/CrashBandicoot.
* CastAsAMask: An interesting aversion: during the fake ceremomy where Lisa confesses, the "Comptroller Atkins" on stage turns out to be Otto [[LatexPerfection in a latex mask]], and his fake comptroller voice, while sounding radically different from Otto's normal voice, was still done by Creator/HarryShearer (Otto's regular voice actor.) And then the ''real'' Comptroller Atkins that shows up for the real ceremony is voiced by Creator/HankAzaria.
* DeathByIrony: Homer stopped Marge from boiling Pinchy. In the end, it's Homer who ended up boiling the lobster by trying to give it a bath.
* DidIJustSayThatOutLoud: While trying to convince Principal Skinner to spend part of the extra funding money on Coleco-brand computers, Gil accidentally mentions something bad about them.
* FelonyMisdemeanor: Lisa worries that an F on her exam will cost her admission to Harvard University, and the only school that would accept her would be [[TakeThat Brown University]].
* FMinusMinus: Inverted Trope. Lisa's test gets an "A-Triple-Plus" (it would have been quadruple, but one of the "plusses" was a stain of Drambuie that Miss Hoover had while grading papers), and with it comes a lot of attention that she ''absolutely detests''.
* HonorBeforeReason: Despite the fact that it would benefit everyone in school, Lisa intends to try and stop it from happening just because she feels bad about cheating when it was her own fault to begin with.
* LatexPerfection: The mask that Otto wears when posing as the comptroller.
* MedalOfDishonor: The "accidental" kind. As mentioned on HonorBeforeReason, Lisa would prefer to throw the school's welfare to the wolves before accepting the reward (and the extra funding money that comes with it, which the school direly needs ''and they have already used some of to buy stuff'').
* NotHelpingYourCase: Willie recommends Lisa not cheat on the test, and just take the F. After all, he got an F once, and his life "turned out just fine." Cue Willie unclogging a school toilet with his bare hands.
--> '''Willie''': Oh, you've got yourself a partner, do ye?
* OutOfCharacterMoment: While it makes sense that Lisa would feel desperate enough to cheat if she didn't know the answers on a test, it does seem unlikely that Lisa wouldn't have already read ''The Wind in the Willows'' since she's the kind of person who would read books like that for fun.
** She also complained against Homer sparing Pinchy the lobster, despite being a vegetarian and a fierce animal lover. Homer even calls her out on it.
* PirateNinjaZombieRobot: Lisa's first time playing the video game has her quitting because ''Ninja Koalas'' kill her character.
* ScrewTheMoneyIHaveRules: Lisa.
* ScrewTheRulesIHaveMoney: Every Springfielder but Lisa.
* ShoutOut:
** Ralph calls Superintendent Chalmers "UsefulNotes/SuperNintendo Chalmers".
** The video game Lisa plays while sick is obviously spoofing ''Franchise/CrashBandicoot''.
* TakeThat: Marge telling Bart that they're not converting to Catholicism because "...three kids is enough, thank you." The Catholic League at the time spoke out against that line.
** The ImagineSpot of Lisa being forced to go to Brown University due to her one "F."
-->'''Skinner''': Mmmm, Brown. Heckuva school. Weren't you at Brown, Otto?
-->'''Otto''': Yup. Almost got tenure, too.
* WhereTheHellIsSpringfield: Superintendent Chalmers claims that Springfield Elementary School used to be considered the most dilapidated in Missouri until they brought it to Springfield. Lisa's and Skinner's looks of surprise when Chalmers mentions "Missouri" suggests that Springfield isn't there.
