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.

* 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's trying to make her know [[ItMakesSenseInContext people makes mistakes and tight jeans are overrated]].

'''Dipper:''' I know.

Blendin's there, [[http://25.media.tumblr.com/tumblr_m90g2vnisn1rr79d5o1_500.jpg fixing]] [[http://25.media.tumblr.com/tumblr_m90g2vnisn1rr79d5o2_250.jpg the]] [[http://25.media.tumblr.com/tumblr_m90g2vnisn1rr79d5o3_250.jpg paradoxes!]]
* 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!"
* 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.
* MeaningfulEcho: The man working the baseball-throwing game tells Dipper "You only get one chance, kid." . [[YouCantFightFate He's right.]]
* NecessaryFail: Turns out in order for Dipper to not hit Wendy with the baseball, Mabel has to lose Waddles.

* 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.]]
* 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.
* ShapedLikeItself: Mabel names her pig Waddles, because it waddles.
** And its previous name was Fifteen Poundy.

** When Dipper and Mabel end up in pioneer times, this exchange occurs.
-->'''Pioneer 1:''' Be on the lookout for mountain lions, travelers.\\
'''Pioneer 2:''' ''(waving a canteen around)'' Dysentery, who wants dysentery?\\
'''Pioneer 3:''' Forge ahead mighty oxen for a new life awaits us on this ''(with emphasis)'' [[VideoGame/TheOregonTrail Oregon Trail]].
** The two TimePolice who show up at the end are named [[Creator/DolphLundgren Lolph and Dundgren]]
*** Which is a little weird because it seems like they intended a reference to ''Film/{{TimeCop}}'', but that starred Creator/JeanClaudeVanDamme.
** "[[Film/{{Babe}} That'll do, pig. That'll do.]]"
* SlapstickKnowsNoGender: Wendy gets hit by a '''lot''' of baseballs in this episode.
* {{Squee}}: Mabel does this when she thinks the pig said her name.
* TalkingAnimal: Mabel thinks Waddles is one of these.
* TemptingFate: Soos comments that the only thing that could possibly cause the rigged dunk tank to dunk Stan is a "futuristic laser arm-cannon." Guess what happens at the end of the episode.

* TyrannosaurusRex: The twins almost get eaten by one when they briefly ended up in the Cretaceous period.
