Lisa becomes a CrosswordPuzzle master and Homer bets money on her competitions to make up for revenue lost from his couples' break-up company.
----
!! Tropes:

* ArmorPiercingQuestion: When Marge voices disapproval of Homer's break-up service, she asks him, "What would happen if there was someone who could break us up every time I had my doubts about you?" It's after this that Homer ends his business.
* BigNo: Homer's response to Lisa changing her last name to "Bouvier."
* BigYes: Homer's response to buying band candy.
* ComicallySmallBribe: When Bart and Lisa's lemonade stand is about to be shut down for not having a proper license, Bart drops some cents to bribe the inspector. It obviously fails.
* ContrivedCoincidence: Homer, Marge, Bart, and Maggie have shirts with the letters to spell Lisa's name and accidentally spell "Ilsa" when Lisa is playing against a rival who goes by that name.
* CreepyChild: When Lisa finds out that Homer bet against her, he asks if she's mad. Lisa responds in an eerily cold tone "No...I'm not mad."
* DisownedParent: Lisa disowns Homer after finding out he had bet against her in a crossword tournament. She goes as far as to change her last name from Simpson to Bouvier.
* EveryoneHasStandards: Homer finds the bartender quite judgmental for taking semi-illegal bets when he shames him for taking a bet against his daughter.
* HiddenDepths: ''[[StrawLoser Gil]]'' of all people turns out to be very good at crosswords.
* LemonadeStandPlot: In this episode, Bart and Lisa start their own lemonade stand before the [[AmoralAttorney blue-haired Lawyer]] shows up and forces them to apply for a vendor's license, where Lisa solves a crossword puzzle for the manager, [[HalfwayPlotSwitch resulting in her becoming obsessed with crossword puzzles and the lemonade stand plot being completely discarded]].
* NomDeMom: When Homer bets against Lisa, it hurts her feelings to the point she decides to use her mother's maiden name out of hatred for him.
* ObfuscatingStupidity: At first, Gil appears hopeless at solving his crossword, spreading Qs in arbitrary squares, and fumbling his glasses. However, the fact that he is in the finals against Lisa should be a strong hint that it is simply a ruse to distract Lisa from winning.
* ObituaryMontage: One of the three musical montagues is about honoring the words that were taken out of the dictionary, with "Fanfare for the Common Man" playing in the background.
* ProxyBreakup: Homer does this for a number of people in Springfield.
* RelationshipRevolvingDoor: [[NoodleIncident At some point]] Edna and Seymour apparently got back together, which we only find out about when Edna is in the process of dumping him again, a task she finally leaves to Homer. This time ''Seymour's'' the one who wants to get married.
* ThrowTheDogABone: A very rare instance with Gil actually succeeding at something, at the cost of him looking like a {{Jerkass}} to a child-like Lisa.
* TranquilFury: When Homer tells Lisa that he has been betting against her, her initial response is a calm, almost stoic expression that goes on for several scenes. Even though she states she's not angry every time Homer asks her.
* TruthInTelevision: A child's lemonade stand getting shut down for not having a vendor's licence (despite the child not being legally old enough to obtain one) might sound like an overreaction and/or the Blue Haired Lawyer being [[AmoralAttorney his usual self]]. It has, in fact, [[https://www.snopes.com/fact-check/have-children-fined-lemonade-stands/#:~:text=%20Children%20have%20been%20fined%20for%20operating%20lemonade,children%20caught%20operating%20lemonade%20stands%20without%20planning%20permission%3A happened in real life]].
* YoureNotMyFather: When Lisa finds out that Homer betted against her, she disowns him. Unlike in "[[Recap/TheSimpsonsS3E8LisasPony Lisa's Pony]]" and "[[Recap/TheSimpsonsS14E8TheDadWhoKnewTooLittle The Dad Who Knew Too Little]]", where she was just angry but eventually forgives Homer, she takes her mother's surname to show that she officially hates him on par with her aunts.
