Episode - 4F13\\
First Aired - 3/2/1997

Inspired by reading a series of books about ''[[Literature/TheBabySittersClub The Babysitter Twins]]'', Lisa decides to become a babysitter -- and finds that her biggest challenge is her own brother. Meanwhile, Homer and Marge check out the new outdoor mall.

!!This episode contains examples of:
* ArtisticLicenseLaw: It's actually illegal to leave children younger than 12 home alone. [[AnthropicPrinciple Then again...]]
* BadlyBatteredBabysitter: Lisa, and as is typical of the Trope, the rest of the town automatically assumes the absolute worst of her attempts to make things right.
* BigEater: Comic Book Guy
-->'''CBG''': Oh loneliness and cheesburgers are a dangerous mix!
* BittersweetEnding: Lisa's reputation as a perfectly reliable babysitter is completely nuked flat overnight by Bart's mischief, but Bart apologizes for doing so and there is a chance she will be able to rebuild it... or maybe Springfield (as is typical of it) forgot their condemnation of her as fast as they placed it on her.
* BlatantLies: At Doctor Nick's clinic, Snake is clutching an obvious gunshot wound to the stomach, but claims he tripped and fell onto a bullet. The receptionist ticks off "Liquor Store Robbery" off a checklist of injury causes.
-->'''Dr. Nick Riviera''': Don't worry. You don't have to make up stories here. Save that for court!
* ComicallyMissingThePoint: Bart mistakes Lisa's demand to go to bed for "going to bread".
* DisproportionateRetribution: While Bart's earlier pranks may have been justified due to his anger over Lisa babysitting him, he goes overboard after getting injured via refusing to get medical attention and trying to make his injuries worse so Lisa will never babysit again.
* DudeWheresMyReward: An in-universe example. In the ''Babysitter Twins'' books that Lisa and Janey were reading, the Babysitters were only rewarded with ''four dollars'' for saving the President's daughter.
* EasilyCondemned: Lisa's public humiliation at the climax happens because everybody in Springfield, who Lisa had babysat for repeatedly throughout the episode and had nothing more to give than praises, immediately assumes the absolute worst (up to and including her being on drugs) and believes her to be a "bad babysitter"...
* EasilyForgiven: ...and yet, the very next day, Flanders calls Lisa and asks her to babysit his children (even after Lisa insists on asking about whether or not he believes she won't get coked up and do horrible things to them, Flanders just stays silent for a beat and then asks when she can get to his home).
* GovernmentConspiracy: One of the prank calls Bart makes is about a UFO.
-->'''Pilot:''' We got a report that a Lisa Simpson spotted a UFO.\\
'''Lisa:''' I didn't see any UFO!\\
'''Pilot:''' That's right, Miss. You didn't. ''[waves off a scientist with a needle]''
* HonorBeforeReason: Bart's excuse for being an utter jerk to his younger babysitter.
* HopeSpot: Lisa comes this close to keeping anyone from finding out about this mess, even after arriving at the boardwalk. Then a startled Quimby calls attention to the three of them.
* Hypocrite: Dr. Hibbert call Lisa to babysit his children, just hours after calling her a bad babysitter in front of the entire town.
* IdiotBall: Held by Homer and Marge when they think Bart will be okay with having his younger sister babysit him.
* ImagineSpot: Lisa tries to call Dr. Hibbert about Bart's condition, but then proceeds to have a spot where she would be blamed for it, therefore ruining her reputation. To her dismay, this ends up happening, albeit toned down with her parents' comments.
* KarmaHoudini: Homer and Marge come across as UnwittingInstigatorOfDoom in this episode as hiring Lisa to babysit Bart couldn’t have possibly ended well do to how utterly humiliating it has to be for Bart. Yet they never receive any consequences for their idiotic decision which nearly got their son killed.
* MathematiciansAnswer: When Flanders calls Lisa to ask her to look after his kids (the day after he became one of the biggest criers of her being a bad babysitter), Lisa insists on asking him if he's not afraid she will not perform something as horrible to them that what they assume she did to Bart. After a Beat, Flanders pretty much dodges the question and just asks when can she get to his home.
* MistakenForJunkie: When a flashlight is shone in Lisa, causing her to recoil from the light, Helen Lovejoy accuses her of being on drugs.
-->'''Homer:''' Gimme the drugs, Lisa.
* MistakenForPrankCall: When Bart is unconscious, Lisa tries calling 9-1-1, but they refuse to take it [[CryingWolf because Bart called earlier about "a sisterectomy, a case of severe butt rot, and a leprechaun fight"]].
* {{Mondegreen}} / IncrediblyLamePun: Bart is seen eating bread after Lisa told him to go to bed, but he, [[{{Jerkass}} being Bart]], tells Lisa that she actually said "go to bread".
* NotWhatItLooksLike: A combination of these (mostly the result of Bart being a jerk) ends up resulting in the public humiliation of Lisa and people thinking she's some kind of psychotic drug junkie and overall ''bad'' babysitter.
* ShoutOut: When asking Homer for help, Ned says he's got "a [[Franchise/TheMuppets Fozzie of a Bear]] of a problem."
* ThisIsGonnaSuck: After Homer and Marge leave, Bart stares angrily at Lisa. She smiles nervously.
* ThrowTheDogABone: Despite all of her trouble, Lisa still gets calls at the end.
* TooDumbToLive: Bart's decision to continue screwing with Lisa after getting a huge bump on his head and ''dislocating his arm'' is to lock himself in his room and repeatedly bash his head against the door to make the bump bigger. He knocks himself out.
* TookALevelInJerkass: Bart, though this is justified, as he is offended over the fact that his little sister is called to boss him around. Plus, he apologizes in the end, so it ends happily. Still, the fact that Bart acted like a jerk was the reason why this episode was panned when it premiered.
