'''Sadlygrove:''' I wouldn't want to play the "I warned you" card... (''deep breath'') '''BUT I WARNED YOU!'''
-->-- ''WesternAnimation/{{Wakfu}}'', "The Dragon-Pig"

A character is (sometimes, quite specifically) warned of the horrible things that can happen if they do '''Action A'''. [[CassandraTruth They blow off the warnings]]. After the terrible things happen, TheCassandra then informs them they have no-one to blame but themselves.

->'''Alice:''' Do not take the ShmuckBait, [[DontTouchItYouIdiot you idiot]]. If you do, terrible things will happen. Do not [[TemptingFate tempt fate]].\\
'''Bob:''' [[WhatCouldPossiblyGoWrong What's the worst that can happen]]?\\
''([[FromBadToWorse terrible things happen]])''\\
'''Alice:''' I Warned You.

That statement, whether or not it uses the StockPhrase "I Warned You" or "I Told You So" is this trope, ''provided '''the warning took place'''''. If it did not, due to PoorCommunicationKills, NotNowKiddo, or the warning not reaching its intended recipient, but the StockPhrase is dropped anyway, the trope has been inverted, not played straight.

Generally -- though not always -- PlayedForDrama if played straight. If PlayedForLaughs, expect TheCassandra to be an [[InsufferableGenius exaggeratively smug]] or [[GoodIsNotNice jerkish]] in using this trope (a likely consistent trait that lent to no-one listening to them in the first place) and at least one indignant victim to try and silence them (usually by yelling a bitter "[[BigShutUp Oh Shut Up!]]").

{{Subverted|Trope}}, TheCassandra has every opportunity to say "I warned you!", but ''doesn't even bat an eye''.

Contrast PoorCommunicationKills, NotNowKiddo, where the information doesn't reach its intended destination. Compare CassandraTruth and IgnoredExpert.

* Gohan says this to Cell in ''Anime/DragonBallZ'', after the Cell Juniors torturing the other heroes and Cell murdering Android 16 causes Gohan to [[SuperpoweredEvilSide go Super Saiyan 2]]. Gohan ''did'' warn Cell about his hidden power, and that Cell shouldn't try to awaken it, but those pesky BloodKnight tendencies Cell inherited from the Saiyans just would't let him turn down the challenge.
* [[spoiler:Kaworu]] kept advising Shinji in ''[[Anime/RebuildOfEvangelion Evangelion 3.0: You Can (Not) Redo]]'' not to go through with [[spoiler:pulling the two lances out of "Lilith"'s body as Kaworu suspected a foul play by Gendo]], but Shinji ignored him and [[spoiler:once again caused an Impact for the second time in his life]].
* In ''Anime/HeartcatchPrettyCure'', Erika attempts to warn Tsubomi that Itsuki [[{{Bifauxnen}} isn't whom she thinks Itsuki is]]. When Tsubomi [[UnsettlingGenderReveal learns the truth]], Erika tells her that she warned her. Many times. Including the fact that she was asleep in class when Itsuki was first around her.
* Just before an iconic scene in ''Manga/OnePiece'', a drunk taking a leak outside [[WretchedHive MockTown]] finds the latest wanted posters. He finds Luffy and Zoro's, and the amount they're worth sobers him up fast -- these were the same pair the bar's patrons, egged on by the Bellamy Pirates, mocked and abused earlier! The drunk goes to warn Bellamy, but the pirate merely dismisses the issue. Those two from before didn't fight back, and anyway, some pirates print up fake wanted posters to bluff others. However, Luffy shows up for completely unrelated reasons and puts a knuckle-shaped dent in Bellamy's cheekbone. As the sheer weight of what happened sinks into the onlookers, all the drunk can say is, "I told you so."
* ''Anime/VariableGeo'': In her first match, [[{{Meganekko}} Kaori]] tries to warn her unnamed opponent that she had no chance of winning, according to their statistical fight data which showed Kaori had her thoroughly outclassed in every area. She even offers her the chance to withdraw without having to [[ADateWithRosiePalms suffer the penalty]], since the match was set at level-1. Her opponent didn't listen.

* In ''ComicBook/{{Bone}}'', Lucius warns the regulars at his tavern not to be taken in by Phoney Bone's Mystery Cow scam. They don't listen to him (or rather, they do, but Phoney tricks them all over again), so after the race ends and the con is exposed, the townsfolk want to lynch Phoney, but are held off by Lucius, who later points out that they have no-one else to blame but themselves for being swindled;
-->'''Lucius:''' But I ''warned'' ya! I told ya you were bein' played for a buncha ''saps'', but ya didn't listen to ''me'', did ja? Huh? Did ja? that's ''right!''

* In their college years, [[ComicBook/FantasticFour Reed Richards]] warned [[SelfDemonstrating/DoctorDoom Victor von Doom]] that he made a few miscalculations that would cause his new invention to malfunction. Victor didn't listen and the machine blew up in his face. Literally. Victor's oh-so-reasonable response was to drop out of college, build a suit of PoweredArmor, take over a country, and spend the rest of his life trying to ruin the lives of Reed Richards and his loved ones in revenge for [[NeverMyFault causing the failure]].
* One rather long series of ''{{Peanuts}}'' comic strips starts with Charlie Brown volunteering for the school spelling bee. Violet (who's sitting behind him) whispers, "Don't do it, you'll just make a fool of yourself!" Charlie Brown doesn't listen, and sadly, [[EpicFail he messes up royally in the first round,]] (his love of baseball causes him to accidentally spell his word, "maze", M-A-Y-S). Violet tells him, "I told you you'd make a fool of yourself. [[FromBadToWorse (And the day only gets worse for poor Charlie Brown from there...)]]
* An early ''ComicStrip/FoxTrot'' storyline had Paige being asked out by a senior student who is known to be a sleazebag, which she accepted even though Peter repeatedly warned her, which Paige dismissed. Of course, he tried to make moves on her, despite saying no, and he only relented after she threatened to mace him (which Paige only brought because Peter made her). After telling Peter what happened, his only response is that he's going to spend weeks taunting her and saying "I told you so," which only made Paige's night worse.

Then Ichigo (having a ''massive'' amount of reiatsu and no control over it, [[UnskilledButStrong hence "clumsy"]]) makes the crystal explode.
-->'''Mayuri:''' DO YOU KNOW HOW MUCH THAT ''COST?''\\
'''Ishida:''' I told you so.

* During Stan and Raven's rematch in Fanfic/YuGiOhTheThousandYearDoor, Raven's newest card The Thief in the Shadows uses his effect to steal the top card of Stan's deck and add it to Raven's hand every time it deals damage. Raven takes Vivian's card this way, and dispite Stan's warning to not summon Vivian, Raven summons Vivian. During her next turn, Vivian refuses to attack Stan, and instead attacks Raven directly.
* ''Escape from the Hokage's Hat'' has Shizune tell Tsunade, while they're travelling with Naruto and Hinata, that they need a proper base of operations so as to properly teach/train Hinata and rehabilitate Naruto (LongStory short, some idiots in Konoha placed multiple PowerLimiter seals on Naruto to limit his growth and brainpower. The rehabilitation is taking place while they travel so no one in Konoha can sabotage Naruto's recovery, [[MamaBear she won't be tempted to kill the villagers]] and prevent Naruto from being exiled from the village.) Tsunade brushes it off saying a base would make for an easy target for the enemy. Fast forward 20 chapters later and the group has been tracked by 3 squads of Kiri hinter-nin (where Naruto and Hinata almost got caught), multiple bounty hunters, a Iwa death squad and other ninja villages want to capture them. Much to Tsunade's dismay and embarrassment, Shizune says "I told you so." whenever she gets the chance.
* In ''Fanfic/BleachFanWorks'', Jolene Meyers, after receiving a negative review from Oshikko, responds as follows.
-->'''Jolene''': [[TemptingFate If my fanfic is so bad, why don't you write your own version, huh]]?
-->'''Oshikko''': Sure I will. Keep in mind, you suggested I do so.
* In ''Fanfic/OriginStory'', Tony Stark says this almost word-for-word to Henry Peter Gyrich after Alex Harris utterly annihilates the ComicBook/{{Thunderbolts}} when the attack Gyrich orders on Harris and her girlfriend Louise results in Louise's hospitalization.
** Likewise, when the Thing is cornered by SHIELD agents, he nonchalantly hands over a folder proving he's got diplomatic immunity as a French ambassador. While one of the agents freaks out, his superior orders him to proceed with the arrest. A few paragraphs later, Tony receives a phone call from an infuriate French official, and the US is slapped with major economic repercussions, with Stark Industries being the first targeted.

* ''{{Film/Gremlins}}''
-->'''Grandfather:''' With Mogwai, comes much responsibility. I cannot sell him at any price.
** Randall Peltzer acquires a mogwai anyway. Warnings about them are ignored and the gremlins run wild.
-->'''Grandfather:''' I warned you. With mogwai comes much responsibility. But you didn't listen.
** Ironically, the warnings ''were'' heeded. The mistake came from ''trusting an analog clock that turned out to be stopped'' because the evil Mogwai (later Gremlin) Spike had sabotaged it. The "do not get them wet" rule being broken was an accident.

* ''Film/IRobot'' has "Somehow, 'I told you so' doesn't quite say it." when the robots start rebelling. Or words to that effect.
* In ''Film/TheMummy1999'' remake, when the Americans find Imhotep's tomb and one of them reads the warning etched on it. Their guide (and DirtyCoward) Beni runs off yelling to beware the curse. They don't believe him thinking he's being superstitious. Of course Imhotep gets loose and starts draining the life of those that opened the casket. One of the Americans manages to escape but with his eyes and tongue taken. As the surviving American rests at a hotel, Beni (now working for Imhotep) tricks said American into meeting with a healer who is really Imhotep in disguise. Before the American is drained, Beni tells him that he did warn them not to open the tomb.
* ''Film/SherlockHolmesAGameOfShadows'' has Moran say this after he shoots a soldier who is blocking his line of fire as he is trying to shoot Watson. Inverted in that there was no way for the soldier to hear the warning. Moran was simply commenting.

* Played for laughs in ''Film/HotShotsPartDeux'' during the flashback. A station hand cries out "Board! Board!", a man reading a newspaper ignores him... until a construction worker walks by with a 24, smacking the man and knocking him out. The other person's reaction? "Warned you. Warned you twice."
* In ''Film/KickAss2'', when The Motherfucker tries to rob a store while holding his guns GangstaStyle, an old man tells him if he doesn't hold his guns properly, the recoil will make the guns fly back into his face. Motherfucker fires, and exactly this happens. The old man tells him off for not listening to him.
* ''{{Film/Death Wish}}'' ''4: The Crackdown:'' at the end of the movie, the fake [[BigBad Nathan White]] kills Paul Kersey's girlfriend, and all he can say is that he [[TooDumbToLive warned him that he would kill her]]. This proves to be the [[FamousLastWords last thing]] [[WhatAnIdiot that he ever says]].
-->'''White''': "I told you...I warned you I'd kill her! I warned you! I'd kill he-" [Kersey fires a grenade, [[LudicrousGibs obliterating White]]].
* ''Film/TheCatInTheHat'' Movie narrowly averts but still plays with this trope when the Fish appears just as the Cat himself has finally been sent away by the understandably angry Sally and Conrad for completely destroying their home. However just before he can go through with saying anything snide, he quickly backs off and leaves the kids alone.
-->'''Fish''': Good Riddance! Now this may not be the time for "''I told you so''" but...
-->''(Pieces of debris from bits of the destroyed house falls down and makes a loud crashing sound as Sally and Conrad [[DeathGlare stare down at the fish, without any hint of amusement in their expressions]])''

* ''WesternAnimation/{{Sealab 2021}}''
** A RunningGag in the episode "In the Closet", in which [[AxCrazy Murphy]] sucker-punches everyone who enters the utility closet they're locked in, declaring "I warned him," when the closest he comes to a warning is "stop it," and then only [[InvertedTrope half the time]].
** In the same episode, however, the trope is played straight when Marco warns Sparks that the door is broken.
--->'''Sparks:''' (''closing door'') It's not broken, you just...\\
(''the door fails to open'')\\
'''Sparks:''' You just press the... you ju... [[CaptainObvious The door's broken]]. Wha-wha-wha-what the hell?\\
'''Marco:''' ''Idiota! Cabeza de piedras!''
* ''WesternAnimation/TheSimpsons''
** "Lisa the Vegetarian", after Lisa has twice questioned the use of meat and her teacher/Lunchlady pressed the "Independent thought alarm."
--->'''Skinner:''' Oh oh. Two independent thought alarms in one day. The students are overstimulated. Willie! Remove all the colored chalk from the classrooms.\\
'''Willie:''' I warned ye! Didn't I warn ye?! That colored chalk was forged by Lucifer himself!
** From, "Kiss Kiss, Bang Bangalore":
--->'''Bart:''' So, Mr. Burns, you're saying my dad has gone insane, and thinks he's a god, and broken off all contact with the outside world?\\
'''Smithers:''' I told you Simpson was a poor choice, sir.\\
'''Mr. Burns:''' You know, Smithers, "I told you so" has a brother. His name is, "Shut the hell up"!
* In ''WesternAnimation/AmericanDad'', [[spoiler:Stan once framed his wife for murder just so he wouldn't have to hear her say "I told you so."]] This episode is even titled "Four Little Words". He realized, though, that he could circumvent this by admitting his guilt before Francine has a chance to say it. It doesn't make her any less enraged, though.
* Psycho, the minion {{Seer|s}} of Dr. Killemoff in ''Toxic Crusaders'' usually says this after his CassandraTruth gets blown off by Killemoff as ridiculous and the good guys win.
* In ''WesternAnimation/{{Wakfu}}'' season 2 episode 5, Sadlygrove tries to warn Yugo, Amalia and Evangelyne of the dangers of the Dragon-Pig's lair, as he's the only one with experience in DungeonCrawling. They pay him no heed, used to ignore the IdiotHero... until the three are struck with a BalefulPolymorph. Grovy then admonishes them with the page quote.
* Brainy Smurf manages to get in a few of these in some episodes of ''WesternAnimation/TheSmurfs'' when he chides his fellow Smurfs about certain actions they failed to take that end up in disaster for the village.
* ''WesternAnimation/CodenameKidsNextDoor''
** In the first of many confrontations, Numbuh Five has a candy stolen by her former candy-hunting partner now rival, Heinrich. And tracks him to a temple where he wishes to use said candy in a ritual to become the king of sweets (it's an odd series). Before he does, he disregards the hieroglyphs, in which Numbuh Five enters and warns him that if he is greedy the candy will taste like asparagus. Heinrich doesn't believe her and proceeds with the ritual. Once it's done, of course, the curse mentioned takes effect and [[NeverMyFault he blames her]]. She retorts she did warn him, [[UnstoppableRage not that it does her any good]]. (Ironically, in a much later episode, [[spoiler:it's revealed that the [[NoodleIncident incident in Guatemala that started their rivalry]] was also caused by him being selfish. That seems to be Heinrich's defining trait.]])
** In "Operation: F.L.A.V.O.R.", when the Delightful Children find the sacred Fourth Flavor, Numbuh Five frantically tells them not to put jimmies on it before tasting it (knowing that putting toppings on ice cream like ''this'' would be sacriledge). They ignore this warning, and bring the wrath of the ice cream gods down upon them. (One of many examples of StupidEvil that has caused their plans to fail, although just like all the other times, they fail to learn from it.)
* In an ''WesternAnimation/OzzyAndDrix'' episode, the villain Strepfinger corners Ozzy inside the lungs with a pistol-like weapon; Ozzy warns him not to fire it, saying that if he misses, he'll blow a hole in the wall and they'll both be blown out. The villain smiles evilly and says, "Well then, I'd better not miss..." Unfortunately for him, he does.
* ''WesternAnimation/PhineasAndFerb'': Doofenshmirtz is once about to lose his home for not paying the mortgage. When Agent P suggests him to ask his ex-wife for money, he refuses, in order to avoid the trope. She warned him not to spend money on the gargoyle statues.
* King Julien from ''WesternAnimation/ThePenguinsOfMadagascar'' hates being told "I told you so!" when he does something wrong. But when he causes chaos to erupt in the zoo in one episode, Skipper has this to say to him:
-->'''Skipper:''' I...told...you...[[SubvertedTrope that this idea was brilliant!]]
* ''WesternAnimation/TeenageMutantNinjaTurtles2012'': In the first episode, when the other three Turtles discover that Mikey [[TheCuckoolanderWasRight was actually right]] about the Kraang being alien brains in [[MobileSuitHuman robotic suits]], Mikey spends the rest of the episode griping about how they didn't listen to him in the first place.
-->'''Mikey:''' See?! It's a brain-thing! I ''told'' you! I ''told'' you!
* In [[EveryEpisodeEnding every episode]] of ''Wheelie and the Chopper Bunch'' Scrambles (the youngest member of the Chopper Bunch) constantly tries to warn Chopper that his plans to bully Wheelie won't work, but Chopper never listens.
-->"I told ya, I told ya!" "I know!" "I told ya, I told ya!"...
* In ''WesternAnimation/StarWarsTheCloneWars'', Asajj Ventress and two of the Nightsisters attempt to assassinate Count Dooku. Ventress warns the Nightsisters not to underestimate Dooku, but they assume they have it in the bag because Dooku is old and in their culture, men are inferior to women. Dooku defeats and throws the three out of his home. The Nightsisters express surprise at how strong he was, and Ventress points out that she warned them.
