In this episode written by Tim Long, Lisa becomes a crossword puzzle master and Homer bets money on her competitions to make up for revenue lost from his couples' break-up company.
- Armor-Piercing Question: When Marge voices disapproval of Homer's break-up service, she asks him, "What would happen if there was someone who can break us up every time I had my doubts about you?" It's after this that Homer ends his business.
- Big "NO!": Homer's response to Lisa changing her last name to "Bouvier."
- Big "YES!": Homer's response to buying band candy.
- Comically Small Bribe: 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.
- Contrived Coincidence: 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.
- Creepy Child: "No...I'm not mad."
- Everyone Has Standards: Homer finds the bartender quite judgmental for taking semi illegal bets when he shames him for taking a bet against his daughter.
- Hidden Depths: Gil of all people turns out to be very good at crosswords.
- Nom de Mom: When Homer bets against Lisa, it hurts her feelings to the point she decides to use her mother's maiden name out of hatred to him.
- Obfuscating Stupidity: 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.
- Throw the Dog a Bone: A very rare instance with Gil actually succeeding at something, at the cost of him looking like a Jerkass to a child like Lisa.
- You're Not My Father: When Lisa found out that Homer betted against her, she disowns him. Unlike in "Lisa's Pony" and "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.
