!!Tropes featured:
* ActOfTrueLove: Sibling version but Bart gives up his relationship and sex with Jenda to save Lisa from ruining her life by dating Milhouse and not going to Yale.
* BadNewsInAGoodWay: After Burns gives Bart Lisa's scholarship
--> '''Bart:''' Listen Lis, I gotta tell ya something. I'm going to Yale.\\
'''Lisa:''' What? I don't want to go the same college as you!\\
'''Bart:''' Then I got some great news, you're ''not'' going to Yale.
* BittersweetEnding: Bart gives up his chance with Jenda so that Lisa will be able to go to Yale, saying he'll find a girl who loves him for who he is, prompting Frink to comment that he will—at the age of 83, only to die one minute later.
-->'''Bart:''' [[BrainTransplant And my brain is put in a...?]]
-->'''Frink:''' [[FutureLoser Pauper's grave]].
* {{Bowdlerisation}}: Channel 4 in the UK cuts out the whole "gay for Moleman" back-and-forth between Bart and Lisa, probably due to the implication of the word "gay" being used as an insult.
* CallBack: Surprisingly, to "[[Recap/TheSimpsonsS6E9HomerBadman Homer Badman]]". Homer succeeded in fulfilling his goal of [[ImagineSpot living under the sea]].
* ConvenientlyTimedDistraction: Bart is working for the Kwik-E-Mart and he makes a delivery to Mr. Burns at his mansion. He is held at gunpoint by Snake's combination phaser/cellphone, but Bart saves Mr. Burns when Snake is distracted by a phone call on his phaser and Bart knocks him out with a large diamond.

* EntitledToHaveYou:
** Jenda is passive aggressive about Bart delaying sleeping with her, then ends up threatening Bart to break up for not having sex with her right that second to save Lisa from ruining her life.
** Milhouse tries to manipulate Lisa into being with him despite her breaking up with him because he's not right for her.
* FlawedPrototype: Homer Simpson owns the first hover car ever made. It scratches the streets it's driven through.
* TheFutureIsShocking: Apparently the future will be full of [[HollywoodCyborg cyborgs]] and human clones.
* FutureLoser:
** Bart as per usual (a lazy slob, though upbeat). Though this time he has a cool girlfriend and there is a possibility for a brighter future in that he might go to college and marry Jenda.
** Lisa further ahead in the future if Bart doesn't let her go to college. She might settle for Milhouse and be miserable with him, with little success at work.
* GuestStar: Creator/AmyPoehler as Jenda and Creator/JohnDiMaggio as Bender.
* HasAType: Marge dumps Homer and ends up dating his lookalike Krusty the Clown.

-->'''Milhouse:''' What's Lisa problem?! Milhouse mother say Milhouse is HANDSOME!!

* MushroomSamba: Ralph has one after Nelson spikes the punch.
* NotDistractedByTheSexy: Jenda is frustrated by Bart constantly being distracted while she's trying to initiate their "first time," ultimately breaking up with him after he runs off to keep Lisa from ruining her life.
* ParentalAbandonment: Nelson does this to Sherri and Terri after they both give birth to twins who're his sons. Ironically doing the same thing his dad did to him.
* PlatonicKissing: Lisa kisses Bart on the cheek after seeing what he does for her in the future.
* {{Pun}}: Homer sees some fish taking away his lawn chair. He grumbles to himself, "Stupid flounders", as a parody of his "Stupid Flanders" CatchPhrase.
* PunBasedTitle: A pun on ''WesternAnimation/{{Futurama}}''.
* ReplacementGoldfish: After they separate, Marge dates Krusty the Clown, who resembles Homer.
* SeriesContinuityError: During Bart and Lisa's argument about which of them is "gay for Moleman", Moleman sadly comments that nobody's gay for him. However, [[Recap/TheSimpsonsS14E17ThreeGaysOfTheCondo a previous episode]] had Moleman taken home by a gay solider in uniform.
* ShoutOut:
** To ''Franchise/PlanetOfTheApes''; Homer and Bart pass a billboard urging people to give apes the vote, saying "[[TemptingFate You won't regret it]]!"

* TakeThat: To ''WesternAnimation/{{Futurama}}'' (which, at the time, was canceled and rerunning on Creator/CartoonNetwork's Creator/AdultSwim line-up)

'''Homer:''' You wish, loser! ''(Homer tosses him out of the car and laughs as he breaks upon hitting the ground.)''
* TeacherStudentRomance: Parodied and subverted at Moe's where Edna tries to seduce 18-year-old Bart. They both agree they can do much better than each other.
* TookALevelInBadass: Milhouse got himself some muscles, but subverted as he still pines after Lisa. He loses them in an even more distant future where he sold all his bone marrow.
* TookALevelInJerkass: Milhouse took one as a teenager, he's willing to let Lisa ruin her life just so he can be with her.
