A cat chasing a car? They've seen it. People [[Franchise/YuGiOh playing card games]] [[ChessWithDeath for the fate of the world]]? They've seen it. They've explained the NoodleIncident ''twice''. They even know what the CowTools are for. Yes, these characters have Seen It All.

The way the trope's portrayed varies depending on the character. They may either become TheStoic since they've seen everything they have, or they may simply be a DeadpanSnarker who happens to also be mildly GenreSavvy. They may or may not also be smug about the fact that they've seen it all already. These portrayals, however, while very common, aren't the only ways to portray this trope.

When the bored residents in an urban center have seen it all, the trope is CityOfWeirdos.

Compare FantasticallyIndifferent, OhNoNotAgain, PrescienceIsPredictable and TheAnticipator. See also SeenItAllSuicide and NothingLeftToDoButDie. Not to be confused with WakeUpGoToSchoolSaveTheWorld. Beings that are ReallySevenHundredYearsOld or from the TimeAbyss have a high chance of having seen it all already. Often happens to a WeirdnessMagnet. Contrast IveNeverSeenAnythingLikeThisBefore. Sister trope to ConditionedToAcceptHorror.



* From TheEighties, [[https://www.youtube.com/watch?v=NX6cjpgG8I8 this commercial]] for Kebler Stripe cookies. A stage magician isn't too impressed by "the old fudge on one side trick", but he takes notice of the part with stripes.
* [[https://www.youtube.com/watch?v=wO_SABDCCu8 The Farmers Insurance guy]]. Not only have he and his people seen every weird fate to befall any house/mode of transportation, he offers tours of a museum dedicated to such events. ("We know a thing or two because we've seen a thing or two.")

[[folder:Anime & Manga]]
* In ''Manga/OnePiece'', it's subtly implied that the further a pirate goes down the Grand Line, a cornucopia of crazy phenomena, (Don Krieg says that Devil Powers like Luffy's are commonplace, for one thing) the more desensitized one gets. On Whole Cake Island, Nami freaks out when she sees a giant talking crocodile. Luffy points out that she shouldn't be shocked by that point, as they had just left an entire city of animal-people beforehand.
* ''Manga/{{Berserk}}'' opens InMediasRes and shows Guts going toe to toe with massive armies and [[EldritchAbomination eldritch abominations]] without batting an eye.
--> '''Priest:''' "Fifty men! You can't seriously mean that you're going up against fifty men!"\\
'''Guts:''' [[{{Foreshadowing}} "Get the hell outta my way."]]
* Evangeline of ''Manga/MahouSenseiNegima'', an ancient [[OurVampiresAreDifferent vampire]] (born circa 1400): the existence of a [[TimeMachine time-travelling device]] impresses her somewhere below the level of a shrug or a nod. She says that overall the ability to travel to the moon, the telephone, and the Internet surprised her far more when they first appeared.
* Keiichi from ''Manga/AhMyGoddess''. Especially the first movie. A girl kisses him, grows wings, and jumps out the window and flies away and he doesn't even blink.
* Kyon, from ''LightNovel/HaruhiSuzumiya''. He even complains in his head that weird stuff is normal to him now.
* Sagara Sōsuke from ''LightNovel/FullMetalPanic'', especially in ''Anime/FullMetalPanicFumoffu''. He and Kaname get stuck in a broken down house that is known for having ghosts. There are a ton of scary, bloody ghosts and corpses that freak Kaname out. For Sōsuke, however, none of it fazes him, and he only notices if they happen to have weapons. The reason being, of course, that he's been [[TheStoic desensitized]] to things like that due to all the wars he's been through. An equally good explanation may be that he has no idea ''why'' it's scary, [[NoSocialSkills having no prior experience with horror movies or ghost stories]] and therefore lacking the social conditioning to react appropriately--all he is looking for is the horrors he's used to (like the telephone-mine). Also, [[TheWoobie ghosts are probably downright comforting when one of your life's less traumatic moments was nearly dying in a plane crash along with your parents when you were three years old]].
* Maiza Avaro from ''LightNovel/{{Baccano}}!'' is an example, both because of some traumatic experiences and because he's [[ReallySevenHundredYearsOld been around long enough]] to ''have'' seen it all.
* In ''LightNovel/{{Durarara}}'', Kasuka Heiwajima's deadpan {{Stoic}}ism never lets up even in the worst or most ridiculous of situations. Oddly enough it doesn't seem to have been caused by growing up with Shizuo, a PersonOfMassDestruction, as a brother, since he had the deadpan expression even when Shizuo first lifted a fridge to try and crush him.
* In ''Anime/PuellaMagiMadokaMagica'', [[spoiler: Homura]] is an example, due to [[spoiler: a GroundhogDayLoop caused by her wish. The reason that she's TheStoic is because she's already experienced the events of the show at least four times already (WordOfGod states she's seen it at least a hundred times)]].
* A similar example in ''VisualNovel/SteinsGate'': [[spoiler:Okabe]] claims that [[spoiler:his endless time-leaping to save Mayuri]] have so desensitized him to the event that he [[spoiler:feels nothing, even when he lets her die to find out the circumstances]]. Kurisu knows it isn't true.
* In ''Manga/{{DNA2}}'', Tomoko comes across a guy with his pants and underwear around his ankles, his shirt open and ''having'' '''her''' ''face'' [[spoiler: it's actually her ex Ryuuji having ''just'' discovered his new shapeshifting powers]], closes the door, lets out one huge scream, sees that things seem normal and then doesn't seem to think much about it after. Even after seeing her ex-boyfriend with a hideously deformed body from absorbing too much DNA from other people, she doesn't seem too phased about everything after that. Being told that someone comes from the future and accidentally shot someone with a bullet that made them turn into a [[ThePornomancer Pornomancer]]? No biggie.
* In ''Manga/CityHunter'', when characters stop being surprised by Ryo and Kaori's antics (or, in Kaori's case, by Saeko's), they have really seen it all.

[[folder:Card Games]]
* Referenced in the ''TabletopGame/MagicTheGathering'' card [[http://gatherer.wizards.com/pages/Card/Details.aspx?multiverseid=26673 Jaded Response]]'s flavor text.
-->''"Calm down everyone; it's nothing we haven't seen before."''

[[folder:Comic Books]]
* One of the funnier works to come out of the ''Comicbook/CivilWar'' storyline was the ''ComicBook/FantasticFour's'' Ben Grimm going to Paris. When The Heroes of Paris urgently enlist his aid, he quips in a bored tone (paraphrased) "What is it? Skrull impostors? A SuperRegistrationAct? A mind controlled clone army?" The French heroes just look at each other in confusion and say no, it's the "Underground Emperor" who wants to collapse Paris by tunneling beneath it. His only response is a teary-eyed "I love Paris".
* A lot of modern versions of Franchise/{{Batman}} go this way. Specifically Creator/GrantMorrison, Creator/WarrenEllis, and Creator/KevinSmith. Justified in that it is hinted that Gotham City and Arkham Asylum (and thus some of its residents) are suffering from a supernatural curse that has resulted in the entire city being the hellhole it is. Thus Batman is probably jaded somewhat to the existence of the supernatural.
-->'''Batman:''' Not a murder method I've seen. And I've seen most of them.
* Franchise/SpiderMan is a combination of this and DeadpanSnarker.
-->'''Spider-Man:''' All the crazy wamajama I've seen in my life I am [[BuffySpeak whatever the opposite of a skeptic is]].
* The citizens of [[Franchise/{{Superman}} Metropolis]], [[Franchise/TheFlash Central City]], [[Comicbook/{{Supergirl}} National City]], [[Franchise/GreenLantern Coast City]]... tend to be this. The citizens of [[Franchise/{{Batman}} Gotham]], on the other hand, are much less savvy than would be expected, although the police force falls closer to this trope.
* Franchise/IncredibleHulk: Rick Jones has this in spades due to the simple fact that random chance has led him to be sidekick to half a dozen major heroes, with heavily implied strange adventures in-between, which has led to him being the poster-boy for CrazyPrepared. He's even written at least one best-selling book about all the weird stuff he goes through as a semi-professional sidekick.
* ComicBook/NickFury is nearly a hundred years old, has been through three wars (UsefulNotes/WorldWarII, Korea, and Vietnam), been through paratrooper school, demolition training, trained with the Army rangers and the Green Berets and worked for the CIA. This was all ''before'' he joined ComicBook/{{SHIELD}}. ''Series/AgentsOfSHIELD'' cultivates a similar mindset. See Blog/SurvivalTipsForSHIELDRecruits in "Web Original."
* The pre-ComicBook/{{Flashpoint}} Jaime Raynes run as the ComicBook/BlueBeetle has Peacemaker, survivor of a thousand {{Noodle Incident}}s throughout Franchise/TheDCU.
-->'''Peacemaker:''' Hey, any alien encounter where you don't end up dead or [[AnalProbing probed]] is a good one. Especially probed.\\
'''Jaime:''' Your stories are getting weirder. You know that, right?
* Every senior agent of the {{ComicBook/BPRD}}, but ComicBook/{{Hellboy}} takes the cake. Not surprising, as he's been a paranormal investigator and monster hunter since the early fifties.
* ''ComicBook/JudgeDredd''. He's been an active street judge for over ''half a century'' and the strip averts ComicBookTime.
* ComicBook/TexWiller and his pards have seen them all. Indian wars? They've been on both sides. Projectiles that kill and desiccate you in a second? They've seen it. Magic? They've seen it, [[ProperlyParanoid and have taken to wear charms to counter it]]. Voodoo-style unkillable zombie? They've ''killed one''. People transforming into monsters? They've met at least three or four variations. People faking magic? They know where to shoot to to expose it. ''Aliens?'' Yeah, they've seen that too. That said, sometimes they encounter things they've not encountered yet. Like that time Yellowstone Park's first guardian tricked some villains into walking on Old Faithful exactly when it erupted (they were surprised by the fact he could tell the timing, not the geyser)...
* ''ComicBook/DisneyDucksComicUniverse'':
** It doesn't come up often, but Donald Duck has been involved in finding El Dorado, the Lost Mines of the Incas ''and'' King Solomon, the Holy Grail (that he broke in the head of a criminal), has an alien {{Love Interest|s}}, and so on, and [[DependingOnTheWriter when the authors remember it]] he's ready for everything.
** Honorable mention to what happened in "Donald and Reginella's Wedding": having dreamed that Reginella (the above-mentioned alien {{Love Interest|s}}) was in trouble he prepared a double-barreled shotgun, plenty of salt shells and a boombox with a horrible song to deal with every threat just in case, and when Reginella's envoy comes to bring him to face an army to save her planet from invaders and herself from [[AndNowYouMustMarryMe having to marry their leader]] Donald is ready-and [[OneManArmy mops the floor with the invaders]].
* In ''Comicbook/SupergirlRebirth: Escape from the Phantom Zone'', a civilian is understandably upset over being thrown into an other-dimensional Hell, being jailed by a mad scientist that wants boil his flesh and turn his soul into fuel for his armor, and watching a girl transforming into a giant psionic dragon. Comicbook/{{Supergirl}} and Comicbook/{{Batgirl}} are absolutely unfazed, though, stating that they know how to deal with the aforementioned shenanigans because they're routine stuff to them.
-->'''Benjamin''': My God, she... She's a '''dragon'''! She split the whole '''city''' apart! This is too much, it's '''crazy'''...\\
'''Batgirl:''' We '''handle''' crazy every week, Ben.

[[folder:Fan Works]]
* [[Franchise/{{Terminator}} Sarah Conner]] in ''[[http://www.tthfanfic.org/Story-22866-4/dogbertcarroll+Copyright+Infringement.htm Copyright Infringement]]'' thinks she's this after dealing with various Terminators. [[Series/BuffyTheVampireSlayer Xander]] and the clones of Buffy, Willow, and Cordelia (named after WesternAnimation/ThePowerpuffGirls) correct her when they point out that they had no trouble believing her story of time-traveling cyborgs before they had proof.
* Said word for word by a newsstand owner in ''[[http://www.fimfiction.net/story/2278/5 Trixcord]]'', after telling [[MadGod Discord]] to buy that newspaper if he wants to keep reading it.
* In ''Fanfic/{{Kage}}'', when [[WesternAnimation/JackieChanAdventures Jade]] sees the [[WesternAnimation/{{WITCH}} Knights of Vengeance]] all together in one place, she notes to herself that she's seen weirder.
** She makes a similar comment when Raythor proves to be a NobleDemon.
-->'''Jade:''' Wow, a bad guy with honor? Now I have seen everything.
* The Italian version of ''FanFic/BattleFantasiaProject'' has a few:
** Every single character from ''Anime/{{Beyblade}}'', due all the weird things that have happened to them in canon and some that have happened between the end of the series and the start of the fanfic (it's mentioned a human character had a hand-to-hand fight with a ''bit beast'', and the human won). To the point that, when finding out someone she knows has a sister who is a MagicalGirl and lives in a computer half the time, she says she has seen weirder and ''points at some canon characters of ''Beyblade'' as evidence''.
** The [[ComicBook/{{WITCH}} Hale family]]. Cornelia is a Magical Girl who has visited a convention of her fans, her mother is revealed to be an older [[WesternAnimation/MyLittlePonyTVSpecials Megan Williams]], and her father is a bank director who [[NoodleIncident has seen too much strange things from customers, robbers and coworkers to get surprised when his wife and daughter spring their secrets on him]].
* [[Series/BuffyTheVampireSlayer Xander]] in ''[[https://www.fanfiction.net/s/2369586/1/The_Nighthawk_Chronicles The Nighthawk Chronicles]]'' is this in spades, partially due to being a fan of DC comics and partially from ten years of fighting the supernatural. Most notably when the WesternAnimation/TeenTitans sit down to watch a horror movie. The other Titans are all terrified; Xander falls asleep and when they insist he had to find the monster scary, Xander [[SincerityMode remarks that he's dated scarier things than that]].
* [[Series/BuffyTheVampireSlayer Xander]] quickly reaches this point in ''[[http://www.tthfanfic.org/Story-11757/Methos+Tales+from+the+Barman.htm Tales from the Barman]]''. Given that he's visited from beings from all dimensions and realities (not all of which enter through the front door), if anyone asks where they are, Xander will give the bar's name, city, country, and planet along with the day's date including year. At one point he's nearly attacked by [[Manga/{{Naruto}} Tsunade and one of her Anbu]] when he opens the closet they're currently in; Xander tells them to feel free to either stay in the closet or come out and have a drink but would they mind getting off him and passing the floor cleaner?
* In ''FanFic/NineMinutes'', while on Skypiea [[Manga/OnePiece Nami]] comes across a giant toad wearing overalls (a transformed Usopp) carrying a large duck with Vivi and Chopper on his back. Nami's sole reaction is to note how much it says about her life that it's still not the weirdest thing she's ever seen.
* [[Series/BuffyTheVampireSlayer Xander]] has seen and done enough in nearly thirty years of being a demon hunter in ''[[http://www.tthfanfic.org/Story-31044-2/ShadowMaster+Things+Unseen+Things+Unknown+and+Things+Yet+to+Be.htm Things Unseen, Things Unknown, and Things Yet to Be]]'' that the idea of [[Anime/{{Sekirei}} a race of aliens participating in a battle royale because of an insane CEO]] is only a little weird.
* In ''[[https://www.fanfiction.net/s/10672092/1/Family-Business Family Business]]'' [[Franchise/GhostBusters Egon Spengler]] is hardly phased that he spent the night possessing his nephew [[Series/BuffyTheVampireSlayer Xander]] given his career as a Ghostbuster.
* Having spent years watching over the [[Literature/TheShining Overlook Hotel]] every winter in ''[[https://www.fanfiction.net/s/10541324/10/First-Knight First Knight]]'', Xander is completely immune to most of the antics the spirit/hellgate controlling it gets up to. Giant flesh eating rats, [[EldritchAbomination tentacled horrors]], [[GenderBender waking up as a woman]], and [[AlternateUniverse meeting alternate versions of himself and his friends]]; none of it remotely fazes him anymore. He kills the rat while treating it like a chore, chastises the girls for talking to the tentacled horror (as they have to start their journey over now), ignores being a woman, and casually converses with the alternates to find out what timeline they're from.
* In ''Fanfic/FateGenesis'', [[Franchise/SonicTheHedgehog Sonic and the gang]] have been through so much craziness that they've taken being transported to the Franchise/{{Nasuverse}} with relative ease.
* ''The Sanctuary Telepath'': Janine has been alive for more than a century ''and'' she's a telepath. Add a brother who can teleport, an antagonistic energy elemental, a best-friend-slash-on-and-off-lover who inspired SherlockHolmes and free access to the Sanctuary Network and you get the woman who discovered that her enemy can (sort of) jump through time and simply called it a "lame trick". Then kicked his ass.
* In ''FanFic/ThisBites'', the Yagara bulls of Water 7 are experienced enough that not only do they barely blink at attempted hijackings, they consider members of "the Union" to be newbies until they get in their first high speed chase.
* In ''[[https://www.tthfanfic.org/Story-30976-72/dogbertcarroll+Glittering+motes.htm All That Glitters]]'' neither [[Series/BuffyTheVampireSlayer Xander]] nor [[Film/{{Labyrinth}} Jareth]] are particularly surprised when the former is wished away to the latter's kingdom beyond noting they both thought it could only be done to babies.
* ''Fanfic/AWildBadficAppearedCommentaries'':
** This is [[VideoGame/EarthBound Ness]]'s general attitude to a lot of the weirdness the crew encounters. This is quite understandable, considering how much of a WidgetSeries the game and [[Franchise/{{Mother}} series he hails from]] is famous for being even by Creator/{{Nintendo}} standards, and how he was apparently written to reflect his game's snarky, mature but childish tone. After all, after one has literally seen and fought a living pile of vomit and an evil cult who wants to paint the world blue (not to mention is currently staying at a mansion run by two magic, giant, almighty floating hands, inhabited by loads and loads of people and fantastical creatures with often superhuman powers from all over the multiverse, from worlds with varying rules on reality, so they can duke it out in magic arenas), it would indeed ''probably'' take quite a bit to surprise them.
---> '''Ness''': Meh, still seen weirder!
** [[spoiler:[[VideoGame/FireEmblemRadiantDawn Ike]]]] and to a slightly lesser extent [[spoiler:[[Franchise/{{Metroid}} Samus Aran]]]] also have this general worldview, albeit in a somewhat different way from Ness; they've witnessed and been involved in so much in their careers as a [[spoiler:mercenary/general]] and [[spoiler:intergalactic bounty hunter]] respectively that nothing really shocks them anymore, whether it be casual brutal violence, boneheaded politics, or blatant racism, and thanks to it are able to very casually talk about rather disturbing subjects. When it comes to pure weirdness, however, they can sometimes still express confusion, considering how their series are some of the less weird games represented in ''VideoGame/SuperSmashBros''.
---> '''[[spoiler:Ike]]''': I swear, I'm being hit with a serious case of Deja vu right now.
** Many of the characters actually express some degree of this, some more than others, being video game characters; party members have, at varying points, casually talked about [[DidYouJustPunchOutCthulhu who has slayed a god before]], going up against their respective games' villains' world-changing evil plot of the week, battle strategy and ways to efficiently kill the most amount of people, dimensional travel, and many, many other things, ignoring or just accepting concepts that would be seen as strange to any normal reader; some things are just perceived as weirder than others according to the character. [[VideoGame/SuperSmashBros The Smashers]] even have a mantra for the things in Smash that somehow manage to weird them out; "It's Master Hand, just accept it." [[AuthorAvatar Erika]] is often the designated one to provide reactions from the perspective of a normal earthling, being technically the only non-video game character (despite being a {{voluntary shapeshift|ing}}er Mii who can turn into an electric flying squirrel Franchise/{{Pokemon}}), and even she seems to be an experienced fandom lurker, having bore witness to fandom, political, and general internet weirdness enough times to react with boredom towards quite a bit of it.
* In ''[[https://www.fanfiction.net/s/11991180/1/A-sunny-day-in-DC A Sunny Day in DC]]'', the [[Franchise/JusticeLeagueOfAmerica Justice League]] not only has protocols in place for people from parallel dimensions, they even have pamphlets for them. So when Comicbook/{{Supergirl}} meets a male Kryptonian who was a man changed into a version of her before being changed into a male again, she just wonders if he has her memories and tells him that everyone in the League has encountered at least one alternate version of themselves.
* Ash, and to various degrees everyone who has known him for a while, is this in ''Fanfic/AProfessorAndAStudent''. Ash sees being challenged to a fight and given a Z-Ring by a deity to be unremarkable (to Kiawe's annoyance), while Tracey and Professor Oak are so used to strange things that Oak literally tells Kukui to not call him about Ash unless he stops breathing or gets kidnapped by a legendary Pokemon.
* ''Fanfic/FateIngensCor'': Zelretch doesn't really care about the threat of Voldemort and the Death Eaters, as he's lived for centuries and has seen many would be conquerors like him rise and fall. He's also unimpressed by the story of Harry Potter, the Boy Who Lived.
* ''Fanfic/TheNewAdventuresOfInvaderZim'': In Episode 14, what's [[OurVampiresAreDifferent Norlock's]] reaction to seeing [[spoiler: the massive energy storm destroying the city]]? Casually commenting on it and calmly going back inside the base.

[[folder:Films -- Animation]]
* By the time ''Anime/ResidentEvilDegeneration'' rolls around, Leon Kennedy has already spent the course of [[VideoGame/ResidentEvil2 three]] [[VideoGame/ResidentEvilTheDarksideChronicles separate]] [[VideoGame/ResidentEvil4 games]] fighting every kind of zombie plague you can imagine, and winds up as TheStoic when he gets sent in again during the movie. He rarely even [[TheStoic changes facial expressions]] throughout the movie, let alone indulge in the [[DeadpanSnarker wisecracking]] he was known for in ''VideoGame/ResidentEvil4''.
* Roxanne in ''WesternAnimation/{{Megamind}}'' is the go-to DamselInDistress and is rescued on a regular basis so that nothing really bothers her. That said, the events of the film go OffTheRails from the norm and everyone gets thrown off.
* The ''WesternAnimation/CuriousGeorge'' movie features a cab driver who claims to have seen it all in New York, even a giant monkey wreaking havoc in the streets. At the end he sees a giant jungle idol in the museum and says, "I haven't seen that before... and now I have."

[[folder:Films -- Live-Action]]
* ''Film/ForrestGump'': Having met JFK (as an All-American running back) and LBJ (as a Vietnam vet), Forrest finds it hard to work up enthusiasm for meeting Nixon (as a ping pong diplomat):
--> "So I went to the White House ''again'', and met the President ''again''..."
* ''Film/MenInBlack'':
** Agent K is the primary example of this. He monitors and fights aliens from around the universe; what we consider weird, he considers just another day on the job.
** J became one in the [[Film/MenInBlackII second film]]. By this point he's no longer a rookie and [[BuffySpeak the flashy thing]] is no longer a novelty.
%%** Z is also a type 1, possibly even more than K.
* The title character of ''Film/MadMax'' has Seen it All by the second film. He doesn't blink when a [[PeekabooCorpse dead body flops out of a truck and onto him]] and he watches calmly through a telescope while a woman is raped and killed. During the climactic chase scene, he's driving a truck with one hand while reloading a shotgun with his right when he realizes [[ItMakesSenseInContext a small child is clinging to the outside of his speeding vehicle.]] He casually puts the shotgun shell in his mouth, grabs the kid with one hand, and lifts him up, over, and into the passenger seat.
* Agent Simmons from the ''Film/{{Transformers}}'' movie. Optimus Prime even noted that they weren't surprised to see the Autobots, they just didn't expect them to show up. He ''does'' seem to be surprised at one thing in the sequel though: that Wheelie has been somehow "tamed" by Mikaela.
-->'''Simmons:''' All my life I've been searching for aliens. And you've got one tied on a leash like a little Chihuahua.
* In the SignatureScene of the 1980's blockbuster film ''Film/CrocodileDundee'', the titular character and his love interest are held up at knife point by some New York City thugs wielding switchblades; instead of being frightened and bartering for their lives to be spared, he simply pulls out a Bowie knife and calmly proclaims, "That's not a knife. Now, ''that's'' a knife." Then the thugs run away in terror.
* In ''Film/GroundhogDay'', Phil Connors finds himself stuck in Punxsutawney, Pennsylvania and reliving Groundhog Day every single time he wakes up. He [[spoiler:kills himself multiple times, but each time he wakes up at 6:00 am like nothing happened]]. Eventually, he decides to use his situation for good and he takes to memorizing the events of the day and getting to know everyone in the town. This eventually leads to him obtaining a vast knowledge of everything that happens and everyone in the town.
* Invoked in ''Film/TheHangoverPartII'':
-->"I'm Mike Tyson. What haven't I seen?"
* Franchise/MarvelCinematicUniverse:
** Agent Coulson, a top agent for S.H.I.E.L.D., appears to have this experience. He's very calm and flat in his demeanor around others, even if they happen to be demigods or monsters of science gone wrong. When he has to call one of his agents, [[spoiler:who is currently playing possum in order to get some info from some criminals]], she audibly cleans house on her captors over the phone while he nonchalantly waits for her to finish, as if on hold and listening to filler music. Notably, this trait is a case of CharacterDevelopment throughout the entire Marvel cinematic universe. In his first appearance in ''Film/IronMan1'', he was rather nervous and unsure of himself. Each subsequent film added more and more to his confidence [[spoiler:until he's killed by Loki in ''Film/{{The Avengers|2012}}''. Though he does get off a very nice PreMortemOneLiner before he goes]].
** Comicbook/CaptainAmerica ''thinks'' he's this. Nick Fury is happy to show him otherwise.
--->'''Cap:''' At this point, I doubt anything would surprise me.\\
'''Nick Fury:''' Ten bucks says you're wrong.
** [[spoiler:Cap witnesses an ''entire aircraft carrier'' sprout propellers and take to the skies. Fury wins the bet]].
* In the last ten minutes of ''Film/MortalKombatAnnihilation'', Jax has this response when he sees Liu Kang and Shao Khan turn into their Animalities.
--> "Well now I've seen everything."
* ''Film/TeenageMutantNinjaTurtles''
** [[OneSceneWonder The unnamed cabbie]], who doesn't even blink when Raphael flips over his cab.
--->'''Man in cab:''' What the hell was that?\\
'''Cabbie:''' Looked like a big turtle in a trench coat. You're going to La Guardia, right?
** Likewise, the pizza-delivery man whose main reaction to delivering a pizza to someone in a sewer is irritation that they shortchanged him and grumbling about needing a new route.

* ''Literature/TheHitchhikersGuideToTheGalaxy''
** Wowbagger the Infinitely Prolonged from ''Literature/LifeTheUniverseAndEverything'', who was [[WhoWantstoLiveForever cursed with eternal life]]. He's watched every single movie in existence thousands of times, and has grown so bored he's resolved to insult every single person in the universe -- in alphabetical order.
** There's also a scene in ''Literature/TheRestaurantAtTheEndOfTheUniverse'' where Zaphod tells a Megadodo Publications desk clerk, "Don't you try to outweird me, three-eyes, I get stranger things than you free with my breakfast cereal."
** And of course Arthur Dent himself eventually becomes this.
* Detective Inspector Jack Spratt of Creator/{{Jasper Fforde}}'s ''Literature/NurseryCrime'' series. Years of dealing with crime among Reading's population of NurseryRhyme characters means that he hardly bats an eyelid over prosecuting the Three Little Pigs for killing the "Big Bad" Wolf, or investigating who killed Humpty Dumpty.
* Miracle Max from ''Literature/ThePrincessBride'', on being given a corpse to revive.
-->'''Max:''' I've seen worse.
* Lheorvine from ''Literature/BlackLegion'' mentions casually that he's seen greater battles since the Siege of Terra. Given how the Siege involved half of the galaxy's military, the largest fleets ever assembled and teeming hordes of ancillary units, he must've seen one hell of battles.
** Similarly, Khayon says that after the Legion Wars, there's little that may shock a Chaos Astarte.
* Creator/GKChesterton's Literature/FatherBrown, a little round priest who has seen it all, and somehow forgiven everyone. In his first story, "The Blue Cross," when the great thief Flambeau waylays him, Father Brown has seen it coming, and has already outsmarted Flambeau before the finale. He has planned out counters for techniques so criminal and horrific that even Flambeau is shocked. The man is CrazyPrepared.\\\
The man, as he points out himself, sits in the confessional, and listens to people telling him about the horrible things they do. He's not likely to be naive. (Indeed, Chesterton was inspired to create the character after overhearing two Cambridge students commenting on the "innocent and ignorant" life of a priest -- who happened to be Chesterton's friend and earlier that day had been talking with him about the horrors of crime.)
* Creator/RobertEHoward's Franchise/{{Conan|TheBarbarian}} has traveled from the frozen wastes of Asgard and Vanaheim (Scandinavia) to the southern jungles of Kush (Central Africa), from beyond the Barachan isles in the west (the Canary islands) to Vendhya (India) in the east, has been a thief, a mercenary, a pirate, a tribal chieftain (of four different tribes in four different parts of the world) and a general all around adventurer before becoming king by his own hand and has fought sorcerers, demons, apemen and giants and discovered lost cities. {{Lampshade|Hanging}}d by Thulsa Doom in one of the later stories, as Conan recounts his experiences and Doom calls Conan a liar as no-one could have lived through so many adventures in the thirty or so years Conan has been alive.
* Lucy from ''Literature/SomeoneElsesWar'' has this attitude, along with an air of general defeat, a direct result from having spent her entire life with the Lord's Resistance Army as an unwilling captive.
* ''Literature/TheDresdenFiles'':
** Wizards eventually develop into this. Harry's been getting there faster than others, but that's because he's on the front line more. It's remarked that (in his 40s-50s, barely a child by [[ReallySevenHundredYearsOld wizard]] standards) he's seen as much as people several times his age. A wizard's Sight not only lets him see the truer nature of things, but ''never lets him forget it''. They will always have the memory, perfectly clear, and even thinking about the subject can trigger a re-viewing.
** At one point, Harry encounters a true EldritchAbomination that preys on fear. When he gets to safety, he meditates and reviews ''all'' of the myriad horribly ugly and terribly beautiful things he's seen with his Sight, reminding himself that he fits this trope so that he can return to the fight. Later, he muses that he's seen so much that even remembering seeing that monster with his Sight only gives him slight pause now.
** At one point, an Entropy Curse guided by someone with a really twisted imagination and ham-fisted flair for the dramatic tried to kill someone with a frozen turkey falling from an airplane and ''spearing'' the target. The target, Harry, and a bunch of [[EliteMooks Black Court Vampires]] were brawling it out, and when the turkey hit, the whole fight stopped. As Harry pointed out, even the nigh-immortal supernatural world can't have truly seen it ''all''.
** A variation of this leads to a [[SugarWiki/MomentOfAwesome CMOA]]: Harry is able to [[spoiler:utterly pwn Nicodemus and almost strangle him to death because he went through so many hard beatings that in their struggle Nick, with all his experience, cannot hurt him ''enough'' to make him let go]].
* A phrase from the book of Ecclesiastes from Literature/TheBible, which is believed to be from the third or fourth century BC, makes it almost OlderThanDirt:
-->''What has been will be again,\\
what has been done will be done again;\\
there is nothing new under the sun.''
* Subverted in one of the Literature/AbleTeam novels when a smirking Egyptian police officer warns some American embassy officials who are about to enter a terrorist safehouse that's been attacked by Able Team that the bodies haven't been covered up yet. The CIA man casually responds that he's seen everything, only to throw up on catching sight of the LudicrousGibs inside.
* Only to be expected in a story featuring vampires and werewolves, but ''Literature/{{Unique}}'' also has Granny Helga. Who has fought "Nazis and vampires and werewolves and demons and demonic Nazi vampire werewolves," and has some very entertaining stories regarding the Third Reich's more outlandish research projects to show for it.
* Rincewind, CosmicPlaything of the ''Literature/{{Discworld}}'', has become this in later books. In ''The Globe: Discworld/TheScienceOfDiscworld II'', he's not at all phased to see himself from an alternate future because by that point in his life he's seen far more disturbing things.

[[folder:Live-Action TV]]
* ''Series/BreakingBad'': Mike Ehrmantraut has been involved in the life of organized crime for so long that almost nothing fazes him. At one point, a chunk of his ear is shot off and his response is ''mild annoyance''. This makes the points where he ''is'' shocked, such as when Walter reveals he put a hit on Gale, all the more noticeable.
* ''Series/BurnNotice'': Michael Weston always knows what to do when things go wrong, he just doesn't know when they'll go wrong.
* ''Series/CSIMiami'': Horatio Caine.
* ''Series/DeadLikeMe'': The reapers are, unsurprisingly, not fazed in the least by the deaths they witness every day, and don't even react to the many {{Necro Non Sequitur}}s with any more than a deadpanned "damn."
* ''Series/DoctorWho'':
** The Doctor has spent the last 900+ years of his life travelling anywhere in space and time, and has been to (and saved) possibly billions of planets.
--->'''Amy:''' Why am I here?\\
'''The Doctor:''' Because... I can't see it anymore. I'm 907, and after a while you just can't... ''see'' it.\\
'''Amy:''' See what?\\
'''The Doctor:''' Anything. I look at a star, and all I see is a big ball of burning gas. And I know how it began and how it will end. And I was probably there both times. And after a while everything is just ''stuff''. And that is the problem: You make all of space and time into your back yard, and what do you have? A ''back yard!'' But ''you'', [[TheWorldIsJustAwesome you can see it]]. And when you see it, ''I'' see it.\\
'''Amy:''' And that was the only reason you took me with you?\\
'''The Doctor:''' ...There are worse reasons.
** Nine, Ten, and Eleven turn into Doctor-y balls of {{squee}} when something they ''haven't'' seen before pops up. Enemies familiar with the Doctor know the one way to lure him into a trap is to present him with a mystery.
* ''Series/{{Farscape}}'': The crew of Moya are some. Crichton even lampshades it in one episode when he refers to aliens messing with their minds as "pulling a T'raltixx," in reference to a previous mindscrew. Scorpius is one as well. Nothing fazes him. Ever.
* ''Series/GetSmart'': Maxwell Smart oozes this trope, especially in some of his [[CatchPhrase catchphrases]], to wit:
** "That's the second biggest [whatever] I've ever seen."
** "Of course, the old [incredibly specific description] trick!"
** "That's the second time I've [or 'they've'] fallen for that this month/week/year!"
* ''Series/{{Heroes}}'': Claude Rains, the {{invisib|ility}}le man, is a former Company [[TheMenInBlack Man in Black]], invisible, and he has alluded to a hobby of randomly following people around, so he's seen a lot.
-->'''Claude:''' People suck, friend! Never forget that!\\\
'''Claude:''' Everyone's like the rest -- that's why they're ''the rest''!
* ''Series/LegendsOfTomorrow''
** ComicBook/JonahHex has already met the time traveler Rip Hunter and shared a few adventures with him, so he's not surprised by futuristic technology nor superpowers. The only thing that phases him is seeing Firestorm in action, which makes him make the sign of the cross.
** In season 2 Damian Darhk, a ReallySevenHundredYearsOld EvilSorcerer is also pretty unfazed by meeting the Legends in [[Recap/LegendsOfTomorrowS2E1OutOfTime 1942]], and the episode [[Recap/LegendsOfTomorrowS2E5Compromised "Compromised"]], his reaction to seeing Obsidian, a metahuman capable of controlling and even becoming [[CastingAShadow darkness]], is a mild "huh".
* ''Series/{{NCIS}}'':
** Not only has [[CreepyMortician Ducky]] seen it all, he'll happily tell anyone within earshot all about it. He once uses this trope to make [=McGee=] comfortable enough to reveal the poison ivy rash on his, er...well, you know...
** Ziva's first case with the team (not including Ari Haswari) involves a Marine dressed as a Civil War soldier, shot with a musket, and BuriedAlive in an antique casket. Tony and [=McGee=] tell her that it's not the strangest case they've investigated.
* ''Series/PowerRangersDinoThunder'': Tommy Oliver tends to give off this vibe, ''especially'' when he got captured by Mesogog ''before'' he got his powers for this season, as his reaction was to snark at him with a very visible lack of panic. Then again, this has been Tommy's ''fifth'' ranger identity; not even the average power ranger at the end of their tenure can compare to what he's been through, hence he's called the "[[LivingLegend Greatest Ranger Ever]]".
* ''Series/{{Revolution}}'': Miles Matheson, of the Weary Traveller variety. Being a marine sergeant before the blackout and being [[spoiler: the number two man in the Monroe Republic]] for years after the blackout would do that to him ("[[Recap/RevolutionS1E3NoQuarter No Quarter]]").
* ''Series/StargateSG1'': ''Everybody'' in the later seasons, possibly the most GenreSavvy group of heroes this side of the Literature/{{Discworld}}. At one point, General Hammond believes Daniel's claim that he has intelligence information from [[PsychicDreamsForEveryone a dream he had]], and explains his credulity with, "The things I've heard sitting in this chair..." Keep in mind he's talking to someone who's died, [[AscendToAHigherPlaneOfExistence Ascended to a Higher Plane of Existence]], and then came BackFromTheDead, ''twice''. This trope is nicely lampshaded when the other team members express surprise at Daniel's immediate belief in a teenager who claims to be their teammate Jack, somehow youthened about 30 years in his sleep for no apparent reason, in "Fragile Balance."
-->'''Daniel:''' Stranger things have happened.\\
'''Teal'c:''' Name but one.\\
'''Daniel Jackson:''' Well, there was the time he got really old; the time he became a caveman; the time we all swapped bodies....
* ''Franchise/StarTrek'': Sometimes happens in later seasons of the series. When something odd happens, they promptly check for everything odd that's happened before, up to and including parallel universes and time travel. "This is Starfleet. Weird is part of the job."
** PlayedForLaughs in the ''Series/StarTrekVoyager'' episode "Message in a Bottle", when Voyager's Doctor meets the EMH of the USS ''Prometheus''. Voyager's Doctor shares some of his past experiences, which include having sexual intercourse, much to the amazement of Prometheus' Doctor.
* ''Series/{{Supernatural}}'':
** The writers like to lampshade the main characters' casual professionalism every now and then.
** One example is the fourth season episode "Death takes a Holiday", where the Winchesters discuss what they know of their latest case (an {{Adventure Town|s}} where everyone is suddenly immortal):
--->'''Sam:''' It seems like the last person to actually die around here was this boy a couple of months ago; we should probably start by contacting him.\\
'''Dean:''' ...I love how matter-of-factly you just said that. Our lives are weird.
** Another example is when they travel back in time to the 1800s because they need the help of veteran hunter Samuel Colt (yes that Samuel Colt). Upon Sam meeting him, and proving who he is with his cell phone, Colt is completely unfazed; when questioned on it, he says "When you've done this job as long as I have, a giant from the future with some magic brick doesn't exactly give you the vapours."
** In an episode of season ten, Dean is abducted, magically de-aged into a fourteen year-old, and locked in a cell in a basement, along with an ordinary woman (also de-aged). The woman is naturally pretty freaked out. Dean is annoyed.
* ''Series/TalesOfTheGoldMonkey'': Then there's Bon-Chance Louis of this short lived and much regretted show who owed his name to having overslept his appointment with the guillotine and dropped little remarks implying he'd been everywhere and done everything.
* ''TheUprightCitizensBrigade'': Played with. One episode featured an ongoing thread in which various couples keep looking at a great house for sale, only to be driven mad after looking into [[TheseAreThingsManWasNotMeantToKnow the bucket!!]]. Another plot thread involved a grizzled DefectiveDetective. When his case eventually brings him to the house he looks in the bucket, looks up at the sky and yells "Don't you think I know that!"
* In an episode of ''Series/WhosTheBoss'', Angela is in a funk when Tony tells her that her assistant talked smack about her behind her back. When she tells this to her mother, she correctly guesses the exact insult ("A two-bit tramp who slept her way to the top"), saying that's what all men say about women in a higher position.

* The song "I've Seen It All" from ''Film/DancerInTheDark'', sung by the main character, who's going blind.

[[folder:New Media]]
* Anyone who reads [[Wiki/TVTropes this wiki]] for too long runs [[TVTropesWillRuinYourLife the risk of becoming like this]].
** [[TVTropesWillRuinYourLife That ship has sailed]]. [[SugarWiki/TVTropesWillEnhanceYourLife With a full crew]].
* RuleThirtyFour would like you to believe that everything that exists has porn of it. ''Webcomic/{{xkcd}}'' [[http://xkcd.com/305/ disagrees.]] [[http://wetriffs.com/ (And now they've done it.)]]

[[folder:Tabletop Games]]
* Sadly, a recurring problem is challenging [=PCs=] when the players have Seen It All, especially if the GameMaster hasn't.
* [[BadassGrandpa Dwarf Longbeards]] in ''TabletopGame/{{Warhammer}} Fantasy Battles'' are immune to Panic due to this.
* The ''TabletopGame/{{GURPS}}'' advantage Unfazeable is meant to reflect this trope. You become immune to intimidation and to fright checks... not because you're incapable of those emotions (that's a different Advantage), but because you're used to this sort of thing.

[[folder:Video Games]]
* In ''VideoGame/KnightsOfTheOldRepublic'', Canderous Ordo, after TheReveal, makes a comment that, "Remember, we're talking about the Force here. At any moment, Malak could fall from the sky and I wouldn't bat an eyelash."
** In ''VideoGame/StarWarsTheOldRepublic'', the Sith Inquisitor is a WeirdnessMagnet for the more mystical elements of the Force, [[ISeeDeadPeople especially Force Ghosts]]. By the time they arrive on Voss, they have become so FantasticallyIndifferent that they act completely ''blasé'' when explaining their plan to enter a dangerous region steeped in the Dark Side, to find a Gormak they'd met whilst Dreamwalking, to cure them of their HeroicRROD from having accidentally bound too many Force-Ghosts [[ManySpiritsInsideOfOne inside of them]].
* Happens a lot to anyone playing any MMORPG, due to the anonymous nature of the users. Anyone can say anything they want, and do, e.g. "I hope your (loved one) gets (expletive) and (action) down the (undesirable region)". Hence being called anything in the real world would perhaps earn an lol from any experienced MMO veteran.
* ''Franchise/MassEffect''
** In the DLC for ''VideoGame/MassEffect2'', [[PlayerCharacter Shepard]] and Liara both became ones.
--->'''Shepard:''' Be ready. I wouldn't be surprised if this summoned a Reaper.\\
'''Liara:''' How many guards does the Shadow Broker have?\\
'''Shepard:''' Told ya.
** In the main game, there's also [[CoolOldLady Matriarch Aethyta]]. She's only a [[OneSceneWonder one shot NPC]], but she outright says that she's seen it all and her stories back it up. Living for a thousand years will do that to a person.
** By ''VideoGame/MassEffect3'', barely anything fazes Shepard anymore. Even finding out that Cerberus made [[spoiler:a clone of him/her]] seems to annoy Shepard, more than genuinely shock him/her.
** In ''VideoGame/MassEffect3'', Mordin is a former special forces soldier and one of the galaxies leading bio-engineers in the field of advanced bioweapons, was a member of a theatre group that played old human musicals, and ran a free hospital in the worst slum of a backwater pirate haven after retirement, which he left behind to fight million year old cybernetic abominations in the galactic core. There really isn't much that he has not seen or done. His completely deadpan response to seeing Javik, who comes from a long extinct race, says it all:
--->'''Mordin:''' A Prothean. Excellent.
*** Made even more remarkable by the fact that members of his species are stated to rarely live beyond the age of 40.
** ''Every'' squad member in the ''Citadel'' DLC. They're all completely unimpressed with the mercenaries gunning for Shepard and just have fun curbstomping them. Even finding out that the mercenaries are led by [[spoiler: a clone of Shepard]] doesn't faze them at all. The only thing that gets a little screwed up is their sentence phrasing. After that they just start lightly mocking Shepard about it.
--->'''Shepard:''' ... [[TheComicallySerious Would you comedians actually shoot something?!]]
* ''VideoGame/ResidentEvil''
** Leon Kennedy in ''VideoGame/ResidentEvil4'' has a brief moment of this partway through the game. After one of the villains undergoes a dramatic OneWingedAngel transformation and emerges as an enormous monster, Leon scoffs "Monsters. At least after this, there'll be one less to worry about." He's also surprised that the very first {{Mook|s}} he kills isn't a zombie, but doesn't seem to react at all when he learns they're being controlled by parasites. He also calls the BigBad "small time" which would imply he doesn't think much of the mission at hand.
** Especially in ''VideoGame/ResidentEvil6''. Just before he, Helena, Jake and Sherry fight the Ustanak, he takes one look at the 12-foot, claw-handed humanoid, mentally files it under "{{Implacable M|an}}en", and tells them, "Welcome to the club. You get used to it."
* All four of the characters in ''VideoGame/Left4Dead'' are like this, which is shown in detail in the comic, where they constantly have to explain things to the (in theory better trained) CEDA officers. ''VideoGame/Left4Dead2'' shows the new characters gradually becoming this.
* The [[ReallySevenHundredYearsOld immortal]] LittleMissSnarker Rachel Alucard from ''VideoGame/BlazBlue'' begins the series with a serious case of seen-it-all-inspired boredom, owing partially to her age and partially to the fact that [[spoiler:she has literally [[GroundhogDayLoop seen it all before]], and she may well be subjected to it all again if you select "Continue" one more time, you sadist]].
* In ''VideoGame/DragonAgeOrigins'', the Warden can end up becoming one by ''[[VideoGame/DragonAgeOriginsAwakening Awakening]]'', lampshading that people tend to need their help everywhere they go and that fighting Dragons, Demons and Darkspawn has become [[FantasticallyIndifferent very]] [[UnusuallyUninterestingSight much]] [[WeirdnessMagnet routine]] for them.
* In ''VideoGame/DragonAgeII'', most of the characters show signs of having seen it all, [[PlayerCharacter Hawke]] and [[UnreliableNarrator Varric]] in particular.
* Most of the characters in ''VideoGame/Persona4Arena'' display this, and for [[VideoGame/{{Persona3}} good]] [[VideoGame/{{Persona 4}} reason]]. Though it stands out more for the [[VideoGame/{{Persona 4}} P4]] cast due to the action taking place in their old stomping grounds.
* ''VideoGame/DawnOfWar'': Zigzagged with the Kasrkins. Hailing from a planet that is literally next door to hell and where there are more soldiers than civilians (enrollment rate is well above 70% and all civilians have serious military training), they have seen the worst of combat and are basically just below {{Space Marine}}s in all-around toughness, and most of their lines tell you that they've already done what you're telling them to do. However, they aren't immune to morale damage, and one of their lines in case this happens is "In all my years I have never seen them do that!".
* In ''VideoGame/{{Dishonored}}'', the Outsider just seems very bored throughout the entire game, with a few rare exceptions. Considering he's [[TimeAbyss at least several thousand years old]] ''and'' [[TheOmniscient can see all possible futures]], you can understand why he acts like he's seen literally everything.
* Anyone with some serious FightingGame experience is bound to show several shades of this. Prepare to have your ass served on a silver platter to an experienced ''VideoGame/MarvelVsCapcom3'' player.
* Almost everyone notes the utter absurdity of fighting [[Anime/CrossAnge mythological dragons]] with giant robots in ''VideoGame/SuperRobotWarsV''. However, [[LightNovel/FullMetalPanic Sousuke Sagara]] takes the entire affair seriously, saying he'll target at whatever he believes is a weak point. Al notes that Sousuke is taking the situation surprisingly well, and Sousuke tells him that he's been through so much weirdness that he doesn't think anything will surprise him anymore.
* As for ''VideoGame/SuperRobotWarsOriginalGeneration'', the Steel Dragon Battalion and its allies have seen all types of alien invasions and monsters that they just roll with what they get and shoot the bad guys down, leaving the newcomers to be surprised at how calm they seem to be.
* Tybir from ''VideoGame/TormentTidesOfNumenera'' has already seen it all and [[ExtremeOmnisexual slept with a fair bit of it]], and whatever oddness the Ninth World throws at him, he usually has a comment relating to it. Even when he s [[spoiler:physically dragged into [[MentalWorld the Labyrinth]]]], he notes it's not the first time he's been in such a place.
* In ''Videogame/TheElderScrollsVSkyrim'', this is the motivation for why the [[BonusBoss Ebony Warrior]] seeks the Dragonborn out and challenges them. He has seen ''everything'', and has been [[WorthyOpponent looking for someone worthy enough]] to [[DeathSeeker end his life and send him to Sovngarde with honor.]]
* Franchise/SonicTheHedgehog has been through so much and seen so many crazy things by the time of ''VideoGame/SonicGenerations'' that the situation with the Time Eater and being trapped in the [[BlankWhiteVoid White]] [[PlaceBeyondTime Space]] gets little reaction from him.
-->'''Tails''': Totally strange.\\
'''Sonic''': No stranger than [[VideoGame/SonicStorybookSeries rescuing genies in magic books]], or [[VideoGame/SonicColors saving aliens in an interstellar amusement park]].

[[folder:Web Comics]]
* ''Webcomic/GirlGenius'':
** The former Seneschal of Mechanicsburg has seen it all: "Don't try to boggle me, Mr. Talking Cat. This is MECHANICSBURG. You are ''by no means'' the [[http://www.girlgeniusonline.com/comic.php?date=20070516 strangest thing in this town!"]]
** [[http://www.girlgeniusonline.com/comic.php?date=20080528 Dr. Sun, too.]]
** [[MemeticBadass Higgs]] as well. He's looked worried exactly twice: When he accidentally insulted [[WarriorPrince Zeetha]], and when two [[MadScientist Sparks]] were getting waaaay too excited about their "experiments".
** [[http://www.girlgeniusonline.com/comic.php?date=20121126 Moloch isn't fazed]] by the mass destruction going on around him, but by the shocked appearance on everyone else's face when they see Agatha's new lightning gun in action.
* ''Webcomic/GunnerkriggCourt'':
** Antimony was practically raised by [[{{Psychopomp}} The Guides]], so she's almost completely unfazed by the supernatural. For example, compare [[BrainBleach Kat's reaction]] to [[EldritchAbomination Ketrak]] with Annie's complete lack of a reaction.
*** And then comes the 'Realm Of The Dead', where the reactions are switched, although this is due to Kat's WeirdnessCensor, as typified in [[http://www.gunnerkrigg.com/?p=1345 this page.]]
** Jones, also. Apparently the fact that she has only seen something similar is [[http://www.gunnerkrigg.com/archive_page.php?comicID=288 greatly disturbing.]]
** While he didn't start off as this, there's [[spoiler:Jack. His only response to a really pissed-off Reynardine is "Oh...you have a, uh, large wolf with you. Okay. Cool. Nice flowers." He ''was'' visibly startled, but he took it in stride]].
* In ''Webcomic/TheOrderOfTheStick'', Xykon does it while having [[ButForMeItWasTuesday difficulty remembering]] ''which'' [[http://www.giantitp.com/comics/oots0110.html guy named Fyron he killed in Cliffport.]]
* ''Webcomic/EightBitTheater''
** Sarda has literally seen everything that ever happened or ever will happen. He has learned every bit of magic ever. You can't beat him, though you can (very rarely) surprise him with extreme stupidity.
** By the end of the comic, Black Mage, Thief and Red Mage had even become aware of the basic jokes of the comic and could see them coming.
* Mulder has this attitude in one of later episodes of ''Webcomic/MonsterOfTheWeek'':
-->'''Scully''': So what, we're dealing with a vet[eran] who kills invisibly through Mind Control?
-->'''Mulder''': Nah, that already happened in Season 2.
-->'''Scully''': A vet who kills invisibly through psychic projection?
-->'''Mulder ''(smug)''''': Season 3, Scully.
* Sha'sana of ''Webcomic/{{Drowtales}}'' is one of the few surviving Dark Elves and shows very little expression, weariness at what the drow have become, and a certain smugness about [[spoiler:the impending disaster of nearly every tainted drow in Chel losing control of her seeds]] while keeping [[spoiler:Sharess' body in the Ninth Tower]], which made many fans dislike her.
* ''Webcomic/TheInexplicableAdventuresOfBob'': Bob has reached this point. Jean is getting there.
* ''Webcomic/ElGoonishShive'' [[http://www.egscomics.com/?date=2002-02-11 shows]] that being an old friend of a fledgling MadScientist is enough:
-->'''Sarah:''' You don't consider goo coming to life news?!\\
'''Elliot:''' Not after some of the stuff I've seen at Tedd's house...
* Ida, the Mayor's assistant from ''Webcomic/TheWordWeary'', doesn't bat an eyelash when her boss trashes his office and throws [[http://wordwearycomic.blogspot.com/2012/03/24-march-2012.html his phone out the window.]]
* In ''Webcomic/RustyAndCo'', the {{hipster}} vampires. [[http://rustyandco.com/comic/level-6-12/ Been there, done that.]]
* In ''Webcomic/LookingForGroup'', Cale insists that seeing Richard hugging Fel-bunny to be the weirdest thing he's ever seen. It doesn't even make Benny's top five.
* ''Webcomic/SaturdayMorningBreakfastCereal'': When a student approaches her old professor with an offer of SextraCredit, he rebukes her because he's already done every possible perverted thing with his wife.
-->'''Professor:''' Nothing you could do to me would even register as pleasure or pain.
* ''Webcomic/SchlockMercenary'': Professor Pau has been kidnapped by the mercenaries, and they make him show them all the horrible things he's been doing. He's convinced they're going to immediately kill him for being the galaxy's greatest monster, [[http://www.schlockmercenary.com/2011-07-01 but they barely even care.]]

[[folder:Western Animation]]
* ''Franchise/DCAnimatedUniverse''
** ComicBook/JonahHex is portrayed this way in ''WesternAnimation/JusticeLeague Unlimited'', where he not only isn't surprised by a group of time traveling superheroes from the future, but he instantly figures it out. To a lesser extent, a bit earlier in ''WesternAnimation/BatmanTheAnimatedSeries''. This bit of dialogue highlights it:
--->'''Jonah Hex:''' Fancy gun belts you've got there. I'm thinking you folks are time travellers.\\
'''Batman:''' Where would you get a crazy idea like that?\\
'''Jonah Hex:''' Experience. I've had an interesting life.
*** In the same episode, Green Lantern thinks he is, but gets proven wrong.
---->'''Smith:''' Be careful -- there are some of the strangest things down at that ranch.\\
'''Green Lantern:''' Don't worry, we've got a lot of experi... (''pterodactyl screeches overhead'') I'm sorry, what were you saying?
** ''WesternAnimation/BatmanBeyond'' which provided a previous page quote, as Terry tells Bruce about the "ghost" supposedly haunting the high school. He expects Bruce to be skeptical, and he is, but not for the reasons Terry expected -- Bruce has encountered too much paranormal phenomena during [[Comicbook/{{Etrigan}} his]] [[Comicbook/VandalSavage days]] [[WesternAnimation/JusticeLeague as]] [[WesternAnimation/BatmanTheAnimatedSeries Batman]] to dismiss the possibility out of hand, but the current story just sounds "too high school" to ring true; [[spoiler: it turns out that it's one of Terry's classmates turned telekinetic stalker instead of a ghost]].
** In ''WesternAnimation/SupermanTheAnimatedSeries'', after a year of dealing with Mr. Mxyzptlk's antics every three months, Clark is pretty much unfazed when weird things start occurring.
-->'''Lois:''' (sees a penguin waddle past) Is that a penguin?\\
'''Clark:''' I'm afraid so.\\
(Lois turns into a horse.)\\
'''Clark:''' Here we go...
* Slappy Squirrel from ''WesternAnimation/{{Animaniacs}}'' has seen so much that's she GenreSavvy nearly to the point of being all-knowing, and practically no-one she's pitted against has a chance of posing her a serious problem.
* Jonah's no more fazed in ''WesternAnimation/BatmanTheBraveAndTheBold'', where being in the future on an alien world, being forced to track down various species to fight, doesn't warrant much surprise. Batman's no stranger either, and seems to take time travel, galactic teleportation and mystic outer planes in his stride.
* Similar to Slappy Squirrel above, WesternAnimation/BugsBunny knows the ins and outs of the cartoon world so well that he's totally unfazed by things that flagrantly defy the laws of physics, and almost never shows any sign of fear in dangerous situations, as he knows that he [[ComicallyInvincibleHero always wins.]] Whether his characterization in the original shorts is ''quite'' GenreSavvy enough to fall into this trope is debatable, but Bob Clampett's "autobiography" of him erases any doubts by revealing that on the rare occasion that he ''does'' seem concerned, it's all an act; he ''always'' knows how the cartoon will end, he just likes to make a show until then.
* ''WesternAnimation/TheFairlyOddParents'': According to WordOfGod, Timmy Turner's new magical dog Sparky is this.
* The Author of the Journals in ''WesternAnimation/GravityFalls'' is a minor example. When he shows Dipper [[spoiler: an ancient UFO buried underneath the town]], he admits that, after raiding the thing for parts so many times, there's no more thrill of discovery, and expresses an envy for Dipper's excitement.
* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'': Mandy is this in spades, and is even immune to irritation (as revealed in the episode with the invisible duck) due to being constantly exposed to Billy's pure stupidity-infused antics, which drove the goddess of chaos (Eris) insane.
* As the series continues, Candace from ''WesternAnimation/PhineasAndFerb'' becomes less and less phased by the crazy antics her brothers get up to. It gets to the point where, in the episode "Mind Share", she immediately accepts that reptilian space aliens swapped bodies with Phineas and his friends.
-->'''Phineas:''' Really? You believe that weird story just like that?\\
'''Candace:''' Yeah, it's been a long summer, kid.
* Skips in ''WesternAnimation/RegularShow'' says "(yeah,) I've seen this before" in response to anything.
* Rick from ''WesternAnimation/RickAndMorty'' has [[DimensionalTraveler dimension-hopped]] so many times that practically nothing fazes him.
** While certainly no Rick, Morty himself has started to show shades of this. This is best showcased when he and Summer are separated from Rick and [[NiceJobBreakingItHero Summer accidentally starts a race war.]]
--->'''Summer:''' Why are you all fighting! Can't you see you're all the same?!\\
'''Morty:''' [[CasualDangerDialog Ah Summer, first race war, huh?]]
* By Season 5 ''WesternAnimation/SamuraiJack'' is become this trope. Earlier in the show, he was openly confused and perplexed by the new world around him, with the show playing him up as being a stranger in a strange land. In Season 5, he's attacked by a flamboyant MusicalAssassin robot, and doesn't even bat an eye. Even upon being SwallowedWhole by a creature so massive its ''teeth'' dwarf trees, Jack only expresses incredulity that [[spoiler:Ashi is still trying to kill him]].
-->'''Jack:''' I've been swallowed by giant monsters before. I'll find a way out.
* ''WesternAnimation/SouthPark'' sees so many strange things that nobody bats an eye at anything short of the entire town being destroyed.
** "Mr. Garrison's Fancy New Vagina":
--->'''Officer:''' So, {{let me get this straight}}. [[ItMakesSenseInContext That woman over there was trying to get to her balls which were in the knees of a black child whose father is a dolphin]].\\
'''Stan:''' Yeah, that's basically it.\\
'''Officer:''' Sounds like an open-and-shut case. All right, let's head 'em out!
** "Pinewood Derby" involves a SecretTestOfCharacter where the supposed alien criminal "Baby Fark [=McGee=]-zax" wants Randy to give him warp travel after doing so with Stan's pinewood derby car. He tells Randy to get rid of space cops who suddenly arrived, leading to this dialogue.
--->'''Officer:''' You're absolutely sure you didn't see an alien land here?\\
'''Randy:''' No, we're sure.\\
'''Officer:''' So then...we're the first aliens you've ever seen?\\
'''Randy:''' That's right, yep, you're the first ones.\\
'''Officer:''' You don't seem that excited about your first contact with alien life.\\
'''Randy:''' ...uh. That's r--that's right! ''[faking surprise]'' Oh, oh my God! Hey everybody, we just made first contact!
* ''WesternAnimation/StevenUniverse'' is slowly growing into this, to the point where he shrugs off his many near death experiences. In "Horror Club", one of his (human) friends apologizes for apparently summoning a vengeful ghost who's attempting to kill them all. His response?
--> '''Steven''': "It happens."
** His father, Greg, seems to be this as well: in "Keystone Motel", when confronted with [[spoiler:Garnet being split into Ruby and Sapphire due to them fighting]], he just sighs and asks Steven [[spoiler:"where's the other one?".]] This is probably because he's been friends with the Gems for years and has been dealing with their shenanigans for longer than Steven's been alive.
* Kup from ''WesternAnimation/TransformersTheMovie'' and G1 TV series is a bit like this. He's always telling war stories of times that were like times like this (to Hot Rod's increasing irritation during the film)... until he sees [[PlanetEater Un]][[GeniusLoci ic]][[EldritchAbomination ron]] eating a planet and has to admit that he's never seen anything like it before. Justified in that Kup's an ancient veteran of the Cybertronian wars -- he's been all over the galaxy doing all kinds of stuff for ''at least'' 9-12 million years. [[TimeAbyss That's about 4 times longer than humanity has walked the Earth]].
* ''WesternAnimation/UncleGrandpa'': Mr. Gus is over a billion years old, so naturally, he's seen it all already. Uncle Grandpa himself is a more subtle example, being such a WeirdnessMagnet (when he's not [[RealityWarper creating the weirdness]]) that not even the most surreal or horrifying of circumstances prompt anything more than a mild "uh-oh" from him. It's more subtle because he enjoys it so much.
%%* ''WesternAnimation/TheVentureBrothers''
%%** Most of the characters are this, with Dr Venture being a very tired type 2; Brock alternating between type 1 and type 2 depending on his mood; Hank bragging about his experiences putting him into type 3; and Dean [[CharacterDevelopment growing]] from an enthusiastic type 3 into a very scared type 2.
%%** On the villain side of things, The Monarch is a type 2, Dr Girlfriend is a rare type 1, Phantom Limb is a type 3, #21 is a type 2 and #24 is a wannabe type 3. Honestly, Jonas Jr. sticks out because he's one of the few characters who ''isn't'' GenreSavvy enough to be this at all.
* ''WesternAnimation/TheGreatGrapeApe'': In "The Indian Grape Call", Grape Ape meets a lady in distress and she greets him with a simple hello. Beegle Beagle is surprised that she didn't shout "YOWW! A GORIL-L-L-L-L-L-LA!" like everyone else who met his friend, and she replies "You've seen one forty-foot purple ape, you've seen them all."
* ''WesternAnimation/RickAndMorty'', besides Grandpa Rick who's seen so much that even the most fantastical things bore him, Morty [[CharacterDevelopment shows signs off this in Season 2]] when he casually asks if it's Summer's first time seeing/causing a race war. By the Season 3 finale, Morty is completely bored hunting aliens for the president and Summer expresses only mild surprise that Rick's memory was erased along with Morty's (both on accident) when she finds them doing "Morty's Mind Blowers".

* There is absolutely ''nothing'' you can confess to an experienced priest that they haven't heard before (with "experienced" meaning "has been in the Church for several decades"). The guidelines for conduct of Mass say that, during a specific part of the Communion, stopping is not allowed. Thus, there is a manual required to be read prior to ordination. It includes everything from a fly landing on the Host to gunmen taking hostages. It's mostly drawn from experience.
* [[http://notalwaysright.com/trial-by-telephone-wire/3553 Some people]] who've worked in tech support have ''heard'' it all.
** Work in any kind of customer service position for long enough and you'll get a worrying look at the human race.
* [[TheChessmaster Master chess players]] are so good primarily because they have seen everything that could come up in a chess game.
* [[TheMedic Medical professionals]] as well. They've heard all the [[BlatantLies weird explanations]] concocted by embarrassed patients hoping to avoid confessing to what happened, ranging from [[CutHimselfShaving cutting oneself shaving]] to falling off of a ladder [[AssShove onto a lamp]] (because he was dusting a ceiling fan while not wearing pants).
** Similarly, mental health professionals of any kind urge their patients/clients to tell them anything and everything and not to worry that it might sound too bizarre, etc., for them to deal with--"We've heard it all".
* [[http://www.aoml.noaa.gov/hrd/tcfaq/C5c.html This]] answer to a FAQ by the US National Oceanic and Atmospheric Administration's Hurricane Research Division:
-->"During each hurricane season, there always appear suggestions that one should simply use [[NukeEm nuclear weapons]] to try and destroy the storms. Apart from the fact that this might not even alter the storm, this approach neglects the problem that the released radioactive fallout would fairly quickly move with the tradewinds to affect land areas and cause devastating environmental problems. '''[[{{Understatement}} Needless to say, this is not a good idea]]'''."
* More experienced college professors are very strict in their approach and their syllabi, with some going as far as to request that students not glue their document pages together.
* Veteran hotel staff can rival ER doctors for seeing almost everything bizarre and disgusting from walking in on people having sex, to cleaning up after a rock band's debauchery and vandalism, to dead bodies in the box spring.
* Science fiction convention committees (and fans who have been in the scene long enough) aren't even going to bat an eyelash when it comes to wacky hijinks, people of all points on the race/age/gender/sexuality spectrum, and strange ideas. They'll merely sigh and put another rule in the convention guidelines about [[ObviousRulePatch not using peanut butter in a cosplay]] or transforming the mattress and hotel staircase into an impromptu sled competition ''next'' year.
* As the old saying goes, "There is one way to do something right, but many ways to do it wrong." Accordingly, teachers (of nearly any subject, academic or otherwise) get treated to a bewildering array of attempts to complete a task/assignment. The good ones will figure out why the student did what they did and incorporate that into future teachings.
* Long-time martial artists have a seemingly-precognitive ability to anticipate someone's attacks, often getting a block or deflection in the way before the attack has even begun. Despite what some of the less-scrupulous instructors would have you believe, this is not because of channelling an inner spiritual energy or some other such chicanery, but because there's only so many ways to attack someone and experienced martial artists have seen pretty much all of them. After a certain amount of practice, the martial artist won't even consciously think about his defences anymore, as they've become second-nature.
