->'''Dipper:''' Here it is Mabel. Our ticket to any moment in history.\\
'''Mabel:''' Let's get two dodos and force them to make out!

The ninth episode of ''WesternAnimation/GravityFalls''.

At a fair hosted by Stan, Dipper ruins a chance to impress Wendy -- in fact, driving her into Robbie's arms -- while Mabel wins a pig she names Waddles. Then Dipper gets his hands on a device lost by a time traveler from the future, and decides to use it to go back in time and fix his mistake -- but it turns out that doing so will cost Mabel her new pet.
!!Tropes in this episode:
* ActuallyPrettyFunny: Everyone laughs at Robbie's humiliation when hot water makes his pants shrink, even Wendy, his new girlfriend.
* AllGirlsWantBadBoys: Discussed by Mabel and Dipper, regarding Robbie.
-->'''Mabel:''' He is ''such'' a jerk.\\
'''Dipper:''' Yeah, but he's a jerk with tight pants and a guitar.
* AttentionDeficitOohShiny: Mabel, when assuring Dipper she'll help him win Wendy.
-->'''Mabel''': Don't worry, brother. Whatever happens I'll be right here, supporting you every step of the-- OHMYGOSHAPIG!! (runs off in excitement)
* BadFuture:
** So apparently, in the future, a time baby will destroy everything and take over humanity. On the plus side, humanity gets time travel.
** On a smaller scale, Dipper refusing to help save Waddles because it would blow his shot at Wendy causes a despondent Mabel to lean against the Shack's totem pole and refuse to leave. Dipper waits more than a month -- until Mabel is covered with vines and has been incorporated into the tour -- to go back in time to help her.
* BigNo: Mabel's reaction when she loses Waddles to Pacifica in one of the alternate timelines.
* BittersweetEnding: Dipper DidNotGetTheGirl, but he's learned not to sacrifice his sister's happiness for his own.
* BrokenAesop: The episode teaches Dipper that it is more important to sacrifice your needs for your sibling. Except that Mabel does not do the same for him. Mind you, it involves manipulating your would-be ex-girlfriend via time travel to do the alternate so maybe it's, "don't betray family for pipe dreams."
* BurnTheWitch: People with TorchesAndPitchforks try to find Mabel after she pretends to be one.
* ByTheLightsOfTheirEyes: Occurs when Dipper and Mabel time-travel into the port-a-john.
* CallBack:
** The Time Baby was mentioned in the FreezeFrameBonus document in the last episode.
** In "The Inconveniencing", Mabel exclaims "the future is in the past" thanks to Smile Dip. And of course the future was indeed in the past thanks to time travel.
** In the end credits, we're reshown the three scenes from past episodes where Blendin made background appearances.
* ChekhovsGun: Soos speculating on what it would take to trigger the rigged dunk tank target early in the episode.
* ConspicuousCG: The shots of the ferris wheel.
* ContinuityCavalcade: Dipper and Mabel's fight over the time machine ends up sending them tumbling around the background of the show's first three episodes.
* ContinuityNod:
** To [[Recap/GravityFallsS1E8IrrationalTreasure "Irrational Treasure"]]: Stan's mention of there being no police around, and a pioneer's swear of "By Trembley!"
** Dipper brings up the lesson he learned from "Double Dipper".

-->'''Stan:''' There it is, Mabel, the cheapest fair money can rent. I spared every expense.
* CutenessProximity: The pig has this effect on Mabel.
* DoubleMeaning: When Dipper is about to willingly lose Wendy to Robbie so Mabel can win Waddles again, he tries to make her understand that [[ItMakesSenseInContext people make mistakes and tight jeans are overrated]].
-->'''Wendy:''' Dude, you lost me.\\
'''Dipper:''' I know.
* EEqualsMCHammer: How Dipper tries to figure out how to avoid hitting Wendy with the baseball.

* FriendOrIdolDecision: Dipper does find a way to win the stuffed animal for Wendy and prevent Robbie from asking her out, but it requires Mabel to lose the chance to win Waddles, making her miserable. Dipper decides that Mabel being happy is more important.
* FunnyBackgroundEvent: Two of them; First, Dipper sees Wendy agree to date Robbie for the first time and a heart-shaped balloon pops behind him. Later, when Dipper finally succeeds in winning Wendy a prize, a guy behind him wins the strongman game and someone shouts "We have a winner!"
* GirlsLoveStuffedAnimals: Wendy and the Duck[=/=]Panda. She declares she wants one upon seeing them as prizes, and when Dipper finally wins one for her, she has an enormous grin on her face.
-->'''Wendy''': This is the best present ever.
* HeroicBSOD: After losing Waddles, Mabel goes through one that lasts ''at least'' a day, a week, and a month.
* InTheHood: After Dipper shows him up, Robbie hides his face in his hood, his nose still sticking out.
* IronicEcho: "Everything's different now." The first time it was said cheerfully by Mabel after she won the pig. The second time it was said by Dipper, with pure despair in his voice, after losing Wendy to Robbie.
* LosingAShoeInTheStruggle: Dipper loses one of his shoes when he chases Mabel through the events of past episodes, and leaves it behind in a past timeline. When Lolph and Dundgren make Blendin Blandin go back and correct all the time paradoxes, he's seen collecting Dipper's shoe as evidence.

* ProtagonistCenteredMorality: Dipper and Mabel steal Blendin's time machine and end up ruining his life and causing all sorts of {{Time Paradox}}es. [[ComedicSociopathy They don't express any regret or guilt for it, and Blendin's arrest and trial are both played for laughs.]]
* RhetoricalQuestionBlunder: Blendin admonishes the twins for stealing his time machine, telling them "Do you have any idea how many rules you just broke?" Then he adds that he's actually asking that, because he wasn't there to document their rule-breaking.
* SelfFulfillingProphecy: Blendin is sent back to prevent a series of time anomalies that occurred only because Dipper and Mabel got their hands on his time machine.
* SetRightWhatOnceWentWrong: The premise of the episode in the view point of Dipper. He can't fix it because hitting Wendy in the eye was meant to happen.
* ShaggyDogStory: At the end, Dipper undoes the effect of the time travel: Wendy and Robbie start dating and Mabel wins Waddles.
