First Aired - 11/13/1994

Due to test scores hitting an all-time low, Principal Skinner instates academic alerts (little slips of paper warning a student that they're failing a subject or subjects) -- and Lisa discovers that she's on the academic alert list for failing gym class. After trying and failing at basketball and volleyball, Apu discovers that Lisa has a talent for dodging objects, and makes her goalie for the town's pee-wee hockey team...which puts her in direct sibling rivalry with Bart.
!!This episode contains examples of:
* AccidentalMisnaming: This episode started the RunningGag of Moe erroneously calling Marge "Midge", despite getting her name right in past episodes.
* AdultsAreUseless: Bart is pummelled by the bullies and ends up getting rescued by Lisa, while Skinner and Mrs. Hoover watch, with Skinner's only comment being that he hardly ever lets his own mother fight battles for himself anymore.
* DisproportionateRetribution: Nelson's reason for beating up Bart? "Wasting teacher's valuable time".
* DoubleStandard: Marge sees Lisa single academic alert and tells her she's concerned and discusses how to sort this out. Bart brings home a stack of alerts as fat as a phone book and Homer offers to get him a present after signing all of them. When Lisa calls him out on this he only replies: "Ah, the mysteries of life."
** It's because its so rare for Lisa not to excel in anything that her failing anything is worrying. While Bart does almost nothing but fail so him being good at something should be rewarded. In this case it was not a matter of gender. Homer also considered it an improvement that Bart didn't try to forge his signature.
* TheCameo: The Monsters on Monster Island (the peninsula) are Mothra, Gamera and Rodan.
* EmbarrassingRescue: Not only does Lisa one-up Bart at sports, but when she rescues him from the bullies everyone (including Skinner) laughs at him. "I hardly ever let mother fight for me anymore!"
* FalseReassurance: In Lisa's ImagineSpot. Monster Island is just a name. It's actually a peninsula.
* FelonyMisdemeanor: Lisa is scared that an F in gym will ruin her life, even costing her a potential presidency.
** Followed by a lifetime of horror on Monster Island.
* FootballHooligans: Hockey hooligans, but the result is the same. "We came for blood!"
* GretzkyHasTheBall: In real hockey, the clock does not run during penalty shots. The episode's writer (Mike Scully) points this out in the DVD commentary -- he's a hockey fan and knows this, but he decided to take some artistic license for the sake of the ending.
* IHaveNoSon: Homer's reaction to his children's good sportsmanship and calling the game a tie instead of fighting is to avoid looking at them and call them both losers.
* IgnoredEpiphany: Snake is moved to tears by Bart and Lisa's actions, and wonders how his life would have been if they had pee-wee hockey when he was a child. He then shrugs it off and proceeds to destroy the arena.
* InsaneTrollLogic: As Jimbo puts it, it's a lucky coincidence Bart happens to be "his sister's brother".
* InsultBackfire: Lisa tricks Bart into running into the front yard in his pajamas.
-->'''Jimbo:''' ''(mockingly)'' Nice [=PJs=] Simpson. Did [[YourMom your mommy]] buy them for ya?\\
'''Bart:''' Of course she did. Who else would have?\\
'''Jimbo:''' ''({{beat}})'' All right Simpson. You win this round.
* IResembleThatRemark: In the words of Ralph Wiggum, "Me fail English. That's unpossible." Lisa insists that her failing gym is the stupidest thing she's ever heard, then fails to throw the scrunched-up paper as far as the bin.
* LoanShark: Moe has fallen afoul of some, to the tune of being sixty-four thousand dollars in debt.
-->'''Moe''': They're gonna take ''my thumbs!''
* NationalAnthem: Krusty is brought out to sing The Star-Spangled Banner before the championship game. He sings half of the first line ("O say can you see") before realizing he can't remember the rest of the words. The crowd boos him, and he quickly regrets not using the cue cards he was offered, even though it's been stated in the early episodes that Krusty is functionally illiterate (though most later episodes imply that Krusty is semi-literate)
* NotSoAboveItAll: Before the game, Marge tries to tell Homer it's wrong to be rooting for either Bart or Lisa over the other, but when Bart gets tripped by Jimbo, Marge loses it, yelling "He tripped my boy! I demand vengeance! '''I WANT VENGEANCE!'''" Fortunately, Marge gets over it by the end of the game.
* ParentalFavoritism: Homer was showing clear favouritism throughout the entire episode to whichever child was better in sports. Bart and Lisa meanwhile utterly ignore him and try to curry favour with Marge.
* RealMenWearPink: Nelson is failing several subjects but doing quite well in Home Economics. "Keep it down, man."
* RunningGag: The first time Moe calls Marge "Midge", despite knowing her name in earlier episodes. And Marge doesn't even correct him.
* SeriousBusiness: All of Springfield takes Bart and Lisa's hockey match seriously. Moe in particular risks losing his thumbs depending on the outcome.
* SpikyHair: Lisa's hair punctures the volleyball team's only ball.
* StrollingThroughTheChaos: Bart and Lisa just skate peacefully while the crowd riots
* TakeThat: To the Apple Newton (Apple's forefather to the [=iPhone=] and [=iPad=]) and its terrible diction, as it reads "Beat up Martin" as "Eat up, Martha". The Newton was widely considered Apple's biggest blunder until Apple Maps in 2012.
** Apple workers themselves even admitted that this moment [[http://www.cnet.com/news/the-simpsons-eat-up-martha-was-the-first-autocorrect-fail/ haunted them for a while,]] with "Eat Up Martha" becoming a nickname for screwing up inputs within the company.
* VandalismBackfire: Bart darkly announces that as vengeance, he tore the head off a stuffed animal named Mr. Honey-Bunny. Lisa then reminds Bart that that was ''his'' beloved childhood toy.
-->'''Bart:''' ''Agh!'' Mr. Honey-Bunny! (''places the head back on and kisses it desperately'')
