->''So maybe everything didn't work out perfectly for Harry. Still, most of his friends survived, he'd gotten married, and was about to become a father. If only he'd have stayed away from the Veil, he wouldn't have had to go back and do everything '''again'''.''

''[[http://www.fanfiction.net/s/4536005/1/Oh_God_Not_Again Oh God, Not Again!]]'' is a ''Literature/HarryPotter'' fanfiction by [[http://www.fanfiction.net/u/674180/Sarah1281 Sarah1281]]. An adult Harry [[PeggySue gets sent back in time]] and makes it his goal in life to [[SetRightWhatOnceWasWrong save as many lives from Voldemort as he can]]. Okay, [[BlatantLies that's a lie, actually]]. Not to say he doesn't do that, but he spends most of his time [[ItAmusedMe enjoying himself]] and [[CrazyAwesome wreaking as much havoc as possible]]. Also an AffectionateParody, so people and events are looked at and discussed from a different perspective when deemed appropriate. Or [[RuleOfFunny funny]].

Well written and hilarious, this story is completed and comes [[FanficRecs/HarryPotterPeggySue highly recommended]].

[[Funny/OhGodNotAgain Has a Funny page.]] This is going to be huge.

Has a darker counterpart in ''FanFic/{{Sisyphus}}''. This fic has also been described as the anti-Sisyphus, and nine out of ten tropers recommend reading this to cope with that fic.

Not to be confused with the trope OhNoNotAgain
!!This fanfic provides examples of:
* AdultsAreUseless: The adults are more useless than usual, but mainly because they don't have knowledge from the future. Harry does sometimes get them involved on purpose when they can help, such as going straight to Dumbledore when Hagrid gets Norbert.
* AllTherapistsAreMuggles: Harry remembers that this was a problem for Cho Chang in recovering from Cedric's death. She needed therapy, but had to edit her story because there weren't any wizarding therapists.
* ArtifactOfAttraction: [[spoiler:Sirius starts to put on the [[ArtifactOfDoom Slytherin Horcrux ring]] despite Harry warning him that it would kill him. He manages to stop himself when Harry says, “Sirius, if you put that on then Snape will have to save your life. SNAPE.”]]
* BadassTeacher: [[spoiler: Sirius takes over as the History of Magic teacher. The badass part comes with the package]].
* BadLiar: When Ron wonders where Ginny got the extra money she was spending on school supplies (which she got from her cut of a [[BlatantLies less-than-accurate book by Lockhart]]), she freaks out and [[SuspiciouslySpecificDenial demands to know if he's implying she stole it]]. Harry thinks to himself that the Weasleys were raised to be honest.
* BigNo: Fred and George when they see the Quidditch field is now [[TheMaze a hedge]] and Harry at one of the times Hermione wins fifty points after he dedicated himself to losing the House Cup.
* BitchInSheepsClothing: Harry is much more of a CloudCuckoolander this time round, causing the general population to view him as somewhere between [[ObfuscatingInsanity batshit insane]] and just full of it, but he's -- usually -- a nice guy, employing Dumbledore's tactics of destroying his foes through politeness and snark. Sometimes, though, he strays right into MagnificentBitch territory:
-->'''Pansy:''' ''[After Rita Skeeter's Pentawizard Playoffs article]'' Stunningly pretty? GRANGER? What was she judged against -- a chipmunk?\\
'''Harry:''' I wouldn't talk if I were you, Pansy. Seeing as I heard you came in third.
* BlatantLies: Used by Harry when a SarcasticConfession just won't cut it.
** Subverted in one instance:
--->'''Molly:''' ''This is much better gossip than last year's 'Albus Dumbledore was madly in love with Gellert Grindelwald.' Honestly, you'd think Rita Skeeter would learn to stop making up such sensational stories. Obviously Dumbledore was struck speechless by the [[BlatantLies blatant lies]] and thus couldn't be bothered to deny it.''
** "How do you know that?" "My psychic scar told me."
** Also, this exchange:
--->'''Snape''': Is there a reason you felt the need to go running off on a suicidal rescue mission without informing a responsible adult, first?\\
'''Harry''': I did get a responsible adult. Professor Lockhart is a Hogwarts Professor and surely Professor Dumbledore wouldn't have hired him if he didn't have complete faith in him.
* BrokenPedestal: Although Harry still obviously respects Dumbledore and tries to maintain something of their old relationship, it's also clear that he's aware of just how fallible Dumbledore is and how many mistakes the old man has made.
* CannonFodder: How the Sorting Hat describes the Gryffindors.
* CasualDangerDialog: Harry uses this (along with a great deal of [[SarcasmMode sarcasm]]) every time he and Voldemort have a showdown.
-->'''Voldemort:''' You have been taught how to duel, Harry Potter?\\
'''Harry:''' I've been taught to drop my wand and summon snakes. Our dueling club was kind of substandard.
* {{Chickification}}: Inverted, but not to the extent of {{Xenafication}}. Fleur does considerably better in the Triwizard Tournament. WordOfGod (God for this universe, not Rowling) says that this is because the reasons for her lowered points in canon (attacked by Grindylows, the dragon breathing fire on her) were chance events not likely to be repeated.
* ComplainingAboutRescuesTheyDontLike: Ginny was quite put out by the lack of heroics involved in Harry's defeat of the basilisk.
* ConsultingMisterPuppet: How people react to Harry talking about his scar. Made more explicit when a frustrated Hermione asks if she should say "sorry" for doubting Harry's scar's "predictions", and Harry inclines his head as though pretending to consult with the scar before answering that the scar says an apology would be nice.
* ConvenientlyTimedAttackFromBehind: [[spoiler: In the final battle, Sirius hits Voldemort from behind]].
* CrazyPrepared: [[spoiler: When Pettigrew is caught, Luna pulls out an animagus-proof jar that her father had her carry around in case she ever ran across an illegal animagus she wanted to capture]].
* TheCuckoolanderWasRight:
** Luna is the only person to figure out [[spoiler:Harry and Sirius had traveled back in time]]. It seemed obvious to her.
** Harry comes off like this to others, as most things he says are bat-shit insane, but slowly people realize that the more over-the-top Harry's predictions are, the more accurate he gets.
* CuteClumsyGirl: Harry gets Tonks an anti-clumsiness ring to help with her Auror training, but figures she'll only wear it for work, suspecting that she likes to be klutzy.
* CutHisHeartOutWithASpoon: When Harry and Lockhart reach an agreement of sorts, Harry adds that if Lockhart tries to steal one of his accomplishments, Harry will beat him to death with a paper napkin.
-->'''Lockhart:''' CAN you beat someone to death with a paper napkin?\\
'''Harry:''' ''[shrugs]'' I'll have fun trying.
* DeathbringerTheAdorable: Averted, much to Harry's dislike. In the original timeline, he and Ginny got a rabbit, and she refused to accept his name suggestion of "Mega Ultra Flame Deathsman", instead going with a more standard "Flopsy".
* DeathByAdaptation: [[spoiler: Mrs. Norris ends up killed by the Basilisk during second year]].
* DeconstructionFic: An affectionate, DeconstructiveParody using the PeggySue framework. Lampshades hung, inconsistencies trounced flat, and characters attacked at angles that reveal new aspects. And it has a ball doing it.
* ADogAteMyHomework: One of the papers Lupin tries to grade was chewed up by the textbook Hagrid assigned.
* DoNotCallMePaul: Only three people are allowed to call Tonks by her birth name [[EmbarrassingFirstName Nymphadora]]. Two of them are Charlie and Cedric because she lost a bet to each of them (and doesn't make such bets anymore). [[LoveInterest Remus]] can call her that as well, [[ObliviousToLove though the significance of it escapes him at first]].
* DoubleStandard: Neville points out to Hermione that attributing their obsession with Quidditch to their gender could be considered sexist.
* DraggedIntoDrag: ''Sort'' of. Draco gets a photo of Harry in a dress ([[ItMakesSenseInContext technically a Boggart Neville made less frightening]]) and sells them to students as collectibles. Harry negotiates for a cut of the profits and is okay with signing them.
* DramaticReading: [[https://www.youtube.com/watch?v=HgskwzTIGsw&index=1&list=PLYNcOqVhTmvb5cDPfr123rqj6HS5hK-6b The Youtube user Lord Starfish has read this fanfic on his show]].
* EverybodyKnewAlready: About dragons being the first task in the Pentawizard Playoffs. Bagman is not pleased that "the champions (and [[spoiler: George]]) all spectacularly failed to react":
-->'''Bagman''' [''Annoyed'']: Oh come on,you could at least pretend to be surprised!\\
'''Harry''' [''Obliging'']: Gosh, this has got to be the most unexpected event I've ever encountered! Dragons? I don't think I've even '''seen''' a dragon!\\
'''Cedric''': That's a little over-the-top, don't you think?\\
'''Harry''': I'm reacting for six people here; take it or leave it.
* EveryoneCanSeeIt: Ron acts shocked at the idea of [[spoiler:asking Hermione to the dance]]. Harry and Neville point out how obvious [[spoiler:his crush on her]] is.
* ExactWords:
-->'''Harry:''' Wait... Didn't Draco order you not to try to save my life or to try and drive me from the castle?\\
'''Dobby:''' Dobby wasn't trying to save the Great Harry Potter's life nor was he trying to send him away from Hogwarts. Dobby was trying to break Harry Potter's arm.
* FamilyUnfriendlyAesop: In-universe. Sirius tells his History of Magic class the story of Voldemort's parents and asks them what the moral is; Lavender suggests, "Don't assume the guy you're feeding love potions is in love with you and stop."
* FantasticRacism:
** Parodied. Luna asks Snape if he is a Living-ist, or someone who judges based on whether or not a person is dead or alive.
** At one point, it's shown that even the Weasleys aren't completely immune to the Pureblood mentality when Ron mentions they never talk about their second cousin who's a Squib (and an accountant). Harry notes that it's to Ron's credit that he doesn't grasp ''why'' the cousin is an outcast and that he's invoking this trope unintentionally.
* FunWithAcronyms: Hermione's [[ZombieAdvocate house-elf rights organization]] becomes SHOE: '''S'''top '''H'''urting '''O'''ur '''E'''lves.
* GeniusDitz: Lockhart is still incompetent as a teacher, but Harry admits he's a genius when it comes to anything dealing with the media.
* GoodThingYouCanHeal: Or at least, Good Thing You Can Get Healed.
-->'''Sphinx:''' Right. Do not worry, though, as I am not permitted to kill you. That said, healers can work all sorts of miracles these days.
* GrammarNazi: Harry trademarked SPEW for his Grammar Nazi organization 'Stop People Abusing Words.' He chose to spell 'Abusing' with an E to be [[{{Irony}} ironic]] (and make it [[FunWithAcronyms fit the acronym]]).
* {{Handwave}}: How Harry goes back in time is barely explained and goes against canon, but the setup barely matters.
* HardWorkHardlyWorks: Draco points out that Hufflepuff never comes out ahead ''because'' working hard is such an ingrained, defining trait of theirs. “What are they going to do? Do exactly what they're supposed to do MORE?"
* HarmfulToMinors: Neville [[spoiler:kills Quirrel in the Chamber of Secrets]] and is understandably shaken by it. Harry and Dumbledore try their best to comfort him.
* HarsherInHindsight[=/=]HilariousInHindsight: An in-universe example. Mentally being an adult lends Harry a different perspective on many incidents, such as now being horrified at Neville's HilariouslyAbusiveChildhood or finally getting that Lockhart was joking when he implied he was more famous than Harry. [[invoked]]
* {{Hypocrite}}: Harry (affectionately) thinks this when [[spoiler: Sirius]] insists Snape should really let go of his resentment. Because [[spoiler: Sirius himself]] [[SarcasmMode is quite mature in those regards]].
* IfYouDieICallYourStuff: Ginny to Harry upon facing the third year Gryffindor vs. Slytherin Quidditch match:
--> "...[I]f you die, can I have your broom?"
* IfYouEverHurtHer: Averted.
-->'''Remus''' [''Dazed'']: Aren't...you going to warn me about breaking [Tonks'] heart?...\\
[[spoiler: '''Sirius''']]: Why, are you planning on breaking her heart?\\
'''Remus''': Well, no, but--\\
[[spoiler: '''Sirius''']]: Then she can handle herself. She is well on her way to becoming an Auror, after all; and I'm sure she could [[GroinAttack castrate you]] far better than I ever could.
* InsaneTrollLogic: Harry does this a few times in order to explain how he knows certain facts that he shouldn't know yet.
* IRejectYourReality:
** In a lighthearted version of this, [[spoiler: Sirius chooses to pretend he was in Majorca instead of Azkaban for over a decade]]. Everyone pretty much goes with it.
** And then there's Luna:
---> "It's not our fault we're not insane," Hermione said, crosssing her arms. "No offense, Luna."\\
"Why would I be offended?" Luna asked. "I've seen your version of sanity. It bores me."
* ItAmusedMe: Much of what Harry does is to avoid the crap that's going to happen, but most of it he does for the hell of it. The main reason he doesn't tell everybody his actual age is that then everyone will then expect him to act like it.
* KarmaHoudini: [[spoiler:Lucius gets away with everything he does. Again]].
* KillItWithFire: Most of the Horcruxes are destroyed using Fiendfyre.
* LampshadeHanging: The story is practically made of them.
* LeaningOnTheFourthWall: When presented with a headline reading "Harry Potter and the Pentawizard Playoffs", Harry muses that it sounds like [[CharacterNameAndTheNounPhrase the title of a book]]...
* LoopholeAbuse:
** In Harry's fourth year, he was supposed to work with antidotes and "turned in a bezoar again".
--->'''Harry:''' It's kind of expensive, but the look on his face and the fact that he can't technically fail me because the assignment was to find a way to save someone from the various poisons makes it all worth it.
** Fred Weasley gets entered into the Pentawizard Playoffs and George wants to enter as well. [[spoiler: Solution: Have him change his name to George "Fred" Weasley and both can participate!]]
* LovePotion: Discussed. When [[spoiler: Sirius]] explains Voldemort's backstory and asks his class what the moral is, Lavender says, “Don't assume the guy your ''[sic]'' feeding love potions is in love with you and stop?", [[{{Squick}} squicking]] Seamus out.
* TheMasquerade: At the Yule Ball, Luna namechecks the wizarding world's policy of hiding from the Muggles.
* MauveShirt: Some readers thought Cedric Diggory was being set up for this, again. "When I was rereading [[Literature/HarryPotterAndTheGobletOfFire GoF]] I noticed how ridiculously likeable [Cedric] was. Seriously, it's like JKR did that just so everyone would be sad when he died…"[[https://www.fanfiction.net/s/4536005/45/Oh_God_Not_Again]] [[spoiler: He's promoted to a supporting character. And doesn't die.]]
* MentalTimeTravel: The way Harry [[spoiler:and Sirius]] end up going back.
* {{Mentors}}: Lockhart mentors Harry in dealing with being a celebrity. They later give advice to Krum.
* MugglesDoItBetter:
** An example appears to explain why Theodore, a Slytherin, is in Muggle Studies. When asked why he was there, Theodore noted that his father learned the hard-way that Muggles weren't as harmless as he thought after being shot on a trip to Las Vegas, and wanted his son to learn as much about Muggles as possible.
** There is also why some students begin to use pens and notebook paper instead of quills and parchment.
* NeverLiveItDown: In-universe. After Harry becomes a participant in the Triwizard Tournament, he complains that the adults are more worried about how he was entered in the tournament and not why:
--> [[spoiler: '''Sirius''']]: If it were any other student potentially in danger, they would probably be highly concerned, but you go after trolls because you're bored.\\
'''Harry''': That was only the one time!
* NoodleIncident:
-->"Well, there ''might'' have been an incident seventh year during a Hogsmeade weekend when [Narcissa Black] was out with her boyfriend involving a frog, a bottle of pink hair dye, and a trampoline," [[spoiler:Sirius]] admitted.
* NoPeriodsPeriod: Averted. Twice. Moaning Myrtle was killed during her "time of the month", which she offers as an explanation of why she's emotionally volatile all the time, while Lavender receives bad news from home that [[spoiler:her pet rabbit has died]] on the date seemingly foretold by Professor Trelawney, and that, worse, her period has also just begun (a revelation which causes the male Gryffindors to make hasty excuses to leave).
* OnlyInItForTheMoney: Well, Harry's ''not'' only interested in money, but he does deliberately project this persona, to the point where he manages to convince everyone that he's not the Heir of Slytherin ... because if he ''were'', he would be profiting off it!
* ParanoiaGambit:
-->'''[[spoiler: Sirius]]:''' It's going to take every ounce of my considerable self-control, but I want to wait until [Snape's] so paranoid he can't sleep before I start in on him.
* PeggySue: Harry [[spoiler:and Sirius]] travel back in time and fix things. When they don't goof around.
* ThePowerOfLove: The story has this to say on the subject.
--> "...What was that last part?" [[spoiler:Sirius]] asked.\\
[[spoiler:"Remus and Tonks got married?"]] Harry repeated innocently.\\
"No, the other last part. The one about [[spoiler:Voldemort killing you," Sirius]] clarified.\\
"Oh, well [[spoiler:he killed me and I had a nice chat with Dumbledore's soul who informed me that just because I was imagining things it didn't make it not real and then]] I got better."\\
[[spoiler:Sirius]] just stared at him.\\
"It gets better," Harry grinned. "Apparently I only [[spoiler: survived]] because of {{the power of love}}."\\
[[spoiler:Sirius]] groaned. "For the record, when you're telling this to other people, try to come up with an explanation that sounds more {{badass}}."
* PowerTrio: DoubleSubverted. While Harry, Ron, and Hermione become friends like before, Neville is added to the ranks right from the get-go, making them a Power Quartet. However, Ron, Hermione, and Neville end up more of a unit without Harry, making them a PowerTrio and him more of the Draco to their Crabbe and Goyle.
* PsychicPowers: Harry's main excuse for knowing what he does is that his scar is psychic. Note that ''he'' is not psychic -- just his scar. Professor Trelawney calls him a Seer by proxy.
* ReplacementGoldfish: [[spoiler: After Mrs. Norris is killed by the basilisk (the only casualty in that incident), Harry and Mrs. Figg send Filch a kitten to Sirius's horror. She's seen working alongside him like Norris had and he seems to like her]].
* TheRival: Draco, but in a way that is far more friendly than in canon. Neither likes the other's friends and they sometimes don't speak to each other, but generally they are on rather good terms. It may be best described as a cross between this and VitriolicBestBuds.
* RuleSixtyThree: Played with: Changing your gender might be one of the consequences of falling asleep during [[spoiler:Sirius']] classes.
* RunningGag:
** Two words: Tax Deductible.
** [[AWizardDidIt Wrackspurts!]]
** Harry's psychic scar.
** Harry's "Oh, that reminds me, Cedric? Graveyards." and Cedric reflexively responding "Run Like Hell."
* SarcasticConfession: Harry constantly tells the truth about how he knows certain things, stating specifically that no one would believe the truth. Now and then, he just uses BlatantLies.
* ScaledUp: [[spoiler:Harry's animagus form is a snake. He uses it to capture Pettigrew]].
* ScrewTheRulesIHaveMoney: Harry is constantly able to bribe [[CorruptBureaucrat government officials]] for whatever he wants, including [[spoiler: a Time Turner for Hermione and a pardon for Sirius]].
* SetRightWhatOnceWasWrong: Harry spends time defeating Voldemort earlier with a far lower body count, but admits that the future he came from was pretty good anyway.
* SheIsNotMyGirlfriend:
-->'''Remus:''' Nymphadora is not my girlfriend!\\
'''Harry:''' She lets you call her [[EmbarrassingFirstName Nymphadora]].
* ShoutOut:
** Luna has seen ''Film/ThePrincessBride'' and read ''Literature/ThePictureOfDorianGray''.
** Moody mentions The Dark Side, unintentionally referencing ''StarWars'' to Harry's amusement.
** Harry tries to convince Cedric that [[{{Peanuts}} the Great Pumpkin is real]].
** Harry [[spoiler: and Sirius]] quote lines from ''WesternAnimation/PinkyAndTheBrain''.
** At one point, Draco smiles, and Harry narrates:
---> '''Harry:''' Draco grinned. Harry was sure that as a result, [[WebVideo/YuGiOhTheAbridgedSeries somewhere a puppy just died]].
** At one point, Snape lampshades this trope.
--->'''Snape:''' POTTER! Enough about your mythological creatures and your obscure Muggle literature!
* SparedByTheAdaptation: [[spoiler: Everyone, [[MyFriendsAndZoidberg except Mrs. Norris]].]]
* TheStationsOfTheCanon: Harry occasionally uses these to earn money by betting on highly improbable events. The most obvious of these is during third year Quidditch match between Gryffindor and Hufflepuff, when Dementors show up out of nowhere to crash the match, despite not being stationed at the school. Cedric catches the Snitch, at which point Harry gets a large payout from students that he'd bet (through a proxy, of course) about the outcome of the match with.
* StunnedSilence: The Death Eaters' reaction when Harry throws off Voldemort's Imperius Curse and proceeds to mouth off at him.
* StupidestThingIveEverHeard:
** At the beginning of Harry's second year:
--->'''Harry:''' [Dobby's] apparently gotten it into his head that Hogwarts is a walking death trap and therefore I'm better off with my Muggle relatives and in particular my Muggle uncle who could snap at any time and try and strangle me. Therefore, he sealed the portal to the platform and Ron and I got bored so we decided not to wait for everyone to fix the mess and just fly here.\\
'''Draco:''' That has got to be the stupidest thing I've ever heard.
** And later...
--->'''George:''' Besides, the Slytherin team apparently couldn't find anybody to spy as they showed up in person. And full Quidditch gear.\\
'''Harry:''' Why in the world are they wearing their Quidditch robes to practice in? That has got to be the stupidest thing I've seen all day.\\
'''Fred:''' All day isn't very long, Harry. It can't be more than ten.
* SureLetsGoWithThat: Played for laughs in Chapter 35.
-->'''[[spoiler: Sirius:]]''' Top box. It was part of my reparation. Of course, the rest of it went to buying Harry a Firebolt but...\\
'''Harry:''' You don't mind because [[spoiler: I'm your godson]] and you love me?\\
'''[[spoiler: Sirius:]]''' ...Let's go with that, sure.
* SurroundedByIdiots: Harry simply considers most of the human population to be mindless sheep.
-->"Harry, you've got 'I will be besieged by the stupidity of the general population' four times this month," Ron pointed out.\\
"Really?" Harry said mildly. "Only four times? This must be a good month, then."
* TalkingIsAFreeAction: After being transported to the graveyard, Cedric, Fred, & Harry discuss what to do (in place of 'run like hell') before Harry stands up to face Voldemort's minion.
* TricksterArchetype: The first thing Harry does when meeting the Weasley twins (again) is trick them into starting a rumor, stunning them and Ron. He later encourages others to try to lose the House Cup, calling it a "Suck-up" Cup. Then there's, well, everything else he does...
* {{Troperiffic}}: Tropes are invoked, discussed and parodied all the time. Several tropes are even mentioned by name -- BlatantLies, CannonFodder, ThePowerOfLove, UnexplainedRecovery (by [[Administrivia/RenamedTropes its old name]], "I Got Better"), {{UST}} and UnresolvedSexualTension (spelled both ways, in fact)...
* UnclePennyBags: Harry both makes and spends money far more extravagantly this time around.
* UnresolvedSexualTension: Harry points out that Ron and Draco's rivalry looks suspiciously like "UST" (Hermione finds it hilarious, while the acronym goes right over Ron's head). He later thinks Ron and Hermione's relationship clearly falls under this as well.
* VitriolicBestBuds: Harry and Draco. See TheRival above.
* AWizardDidIt: A couple times, when someone asks how Harry knows something, he says it's “Magic” and refuses to elaborate.
* WorldOfSnark: Unsurprisingly, given the source material. Harry, of course, gets to do it the most, but most of the characters, even background ones, get a few snarky lines. A special mention should probably go to Neville, given how a few changes in his first scenes make a huge difference between his canon self and what he is like in the fanfic.
* WorstWhateverEver: [[spoiler:Sirius]] calls himself the worst guardian ever after [[spoiler:Harry dies again]]. Harry assures him he couldn't possibly be worse than the Dursleys were. [[DamnedByFaintPraise For some reason]], [[spoiler:Sirius]] doesn't find this comforting.
* WorthIt: In a rare serious example, [[spoiler:Harry has to tell himself that it's worth it to be obnoxious to Voldemort even when he's being hit by yet another Cruciatus curse]].
