->''"I don't suffer from insanity, I enjoy every minute of it."''
-->-- '''A fridge magnet'''

For a very long time, TV writers seemed to think that one of the universal signs of mental illness was a total inability to perceive one's self as acting oddly. It's tempting to have a mentally ill person utter such classic MadScientist lines as, "TheyCalledMeMad, but I'm not mad, ''they're'' the ones that are mad!" And certainly, the near sociopathically quirky characters you find on the average SitCom seem to think themselves perfectly ordinary, and in RealLife, some people afflicted by mental illnesses don't realise there's anything wrong with them.

Fortunately, this is not always the case. Few characters can be more fun than the Self-Aware Loon. He's crazy and he ''knows'' it. And he's [[InsultBackfire making the best of it.]] Trying to dissuade them from following their [[InsaneTrollLogic crazy, broken logic]] by [[YoureInsane pointing out their insanity]] will never, ever work. To them, it will be the sincerest form of flattery.

They may be a TalkativeLoon most of the time, but they have their lucid moments, and may even consider their episodes to be a welcome respite from normalcy.

Consequentially, they often get to say clever lines like, "Well, I think it's a good idea, but then, I'm crazy," "I'm crazy, but I'm not ''stupid''," "I may be insane, but you're ''crazy''" or "Oh yes, I'm insane. And you're stuck here with me."

Mostly characters who have become unhinged by an exceptional ordeal; rarely results from an organic disorder. Often a facet of the WaifProphet or the RabidCop; and frequently a major character component of the ShellShockedVeteran and [[BadassArmy Special Forces]] military types.

Usually a fun character, and a little cartoonish, though it can also be played tragically (this is how it usually goes when TheMadHatter's illness is organic in origin) as a character is overcome by the knowledge that they are losing their mind and are powerless to stop it. Can also be played for horror, if the affliction [[AxCrazy goes beyond]] "quirky", as such characters can [[HeelRealization know exactly what they are doing]], and [[IgnoredEpiphany just not care.]]

This trope could be considered insensitive to viewers with actual mental illnesses. On the other hand, perhaps they can take some solace in a depiction of mild mental illness as something that can be coped with. And as with issues like ethnicity and disability, when characters have a sense of humor about their condition, it may not come off as ''too'' insensitive.

Archetype is named for the character from ''Literature/AlicesAdventuresInWonderland'', who, like most of Wonderland's residents, knows just how crazy he is, and has decided to just sit back and enjoy it. Carroll's Mad Hatter is in turn a reference to the tendency of Victorian era hatters to go mad. "As mad as a hatter" was even a common phrase at the time. The actual cause of the phenomena was the presence of mercury in the solution used by hatters to shape and form the felt. The hatter would inhale and ingest trace amounts of mercury during his work and eventually suffer from mercury poisoning, leading to dementia and death. Contrary to popular belief, Carroll never actually refers to the character as "the Mad Hatter" in the book; he is simply called "the Hatter".

[[folder:Anime & Manga]]
* ''Manga/{{Hellsing}}'':
** Jan Valentine fits the trope, sociopathically so. Despite being the loopy one compared to his brother, Luke, Jan is the superior soldier and sets off the fall of the Hellsing Organization for no real clear motivation except that he thinks it might be fun to do so. Millenium kills him for divulging information, but even so he goes out screaming, laughing, and flipping the bird.
** Vastly superseded by [[BigBad the Major]] himself, who [[CrazyAwesome delightfully revels]] in the fact that he and [[{{Ghostapo}} his troops]] are quite insane and how they wish to spread their madness to every corner of the Earth. He is also eager to tell anyone who will listen about [[BloodKnight his intense love of war]] and how he has turned Millenium into an army with [[ChaoticEvil no other purpose than to wage constant war]] [[DeathSeeker until every one of them goes out in a blaze of glory]].
* ''LightNovel/HighSchoolDXD'' has Freed Sellzen, who in the dub refers to himself as a "psycho priest free agent," right before he reveals that he willingly became a chimera and ate two devils.
* Break of ''Manga/PandoraHearts'', although he is often using ObfuscatingStupidity. To drive the point home, his Chain ''is'' the Mad Hatter itself.
* ''Anime/CodeGeass'': Lelouch is the Mad Hatter in ''Nunnaly in Wonderland''. The first thing he does is [[http://www.youtube.com/watch?v=WLYMePNrD3c laughing mad]].
* Just about everyone in ''LightNovel/{{Baccano}}'' qualifies, but the reigning champion would definitely be [[spoiler:Claire Stanfield]], AKA "the Rail Tracer". He's so crazy that just about everyone in the cast (including ''himself'') has a moment where they question if he's even human. And he couldn't be happier with his mental illness.

[[folder:Comic Books]]
* ComicBook/TheJoker from ''Franchise/{{Batman}}'' is sometimes depicted this way, as are several other Arkham Asylum patients, including Jervis Tetch -- who calls himself The Mad Hatter. Even Batman himself makes neutral-to-positive references to having mental problems.
** The Joker has claimed that the only difference between Batman and himself is what their insanity drives them to do.
** "He's just one man; dressed like a lunatic and armed to the teeth."
*** He also once described himself as "a certified, card-carrying, lock-me-up-throw-away-the-key looney!"
*** A number of Batman's {{Alternative Character Interpretation}}s state that he '''''is''''' certifiably crazy - just in a [[ReluctantPsycho constructive manner]]. ''ComicBook/TheKillingJoke'' ends on this:
----> '''Joker''': ''See, there were these two guys in a lunatic asylum... And one night, one night they decide they don't like living in an asylum any more. They decide they're going to escape! So, like, they get up onto the roof, and there, just across this narrow gap, they see the rooftops of the town, stretching away in the moonlight... Stretching away to freedom. Now the first guy, he jumps straight across with no problem. But his friend, his friend daren't make the leap. Y'see... Y'see, he's afraid of falling. So then the first guy has an idea... He says, hey! I have my flashlight with me. I'll shine it across the gap between the buildings. You can walk along the beam and join me! B-but the second guy just shakes his head. He suh- says... He says, Wh-what do you think I am? Crazy? You'd turn it off when I was halfway across!''
----> ''*[[OoCIsSeriousBusiness Batman cracks up laughing]].*''
** Funnily enough, Jervis Tech (aka TheMadHatter) is often portrayed as being afflicted with a serious mental illness (typically schizophrenia) and gets upset if called insane.
** [[Comicbook/ArkhamAsylumASeriousHouseOnSeriousEarth Amadeus Arkham]] pities the poor shades confined to the Euclidean prison that is sanity.
* Delirium of [[ComicBook/TheSandman the Endless]] is completely aware that she's insane. She's also aware that everyone else is insane, and that she's ''sane'', and that she's a fish who swims in an ocean of words. With great concentration, she ''can'' force herself to align to more or less the same mental frequency that the rest of the universe runs on, but it's implied that it hurts her. Evidently she was once Delight, until some great cosmic truth happened to her and [[GoMadFromTheRevelation drove her to madness]].
* ''ComicBook/{{Deadpool}}'' occasionally describes himself as an "addled moron", although it's never clear how much he's pretending to be stark staring mad and how much of it is ''actually'' being stark staring mad. DependingOnTheWriter, of course. Considering a couple of times has him with three different thought bubbles going, each with separate personalities? Not MUCH is pretending during those interpretations. It's really hard to put Deadpool in any one category when it comes to this, what with being Ax-Crazy, borderline Cloudcuckoolander, aware of the fourth wall, extremely genre savvy, and just plain insane 100% of the time. The voices in his head often display awareness of events and information that Deadpool himself could not possibly be aware of, and continually act as "white noise" in his head, making it even harder for him to focus on any one thing. An actual in-universe reasoning for the changes in "how" crazy Deadpool is: since his healing factor is out of control (his body is somewhat accurately described as "walking talking cancer") even his BRAIN is rewiring itself with some regularity. Of course, then there's the fact that he's one of the few that completely ignores the fourth wall; he may have learned about the fact that he's in a comic book and, while he loves it, he [[GoneMadFromTheRevelation may have been affected.]]
* ''ComicBook/TheCreeper'', especially in his later versions where his insanity basically keeps Ryder sane or is tempting and fun for him.
* Marv from ''ComicBook/SinCity'', who's aware he's borderline psychotic (and considers himself less clever than he really is). "I've got a condition. I get confused." He also worries about "turn(ing) into what they always said [he] was gonna turn into- a maniac, a psycho killer." In fact, when he uncovers the truth, he takes some time to find more evidence, just to be sure his mind isn't playing tricks on him.
* ''ComicBook/JohnnyTheHomicidalManiac'' often wonders if he's really crazy. By series end, he pretty much seems to revel in it.
* Rosy the Rascal, Amy's evil counterpart from an alternate universe in the Comicbook/SonicTheHedgehog comic series. A mentally unbalanced clingy jealous girl taken to the extreme (she believes the only way to get Scourge (evil Sonic)'s attention is to smash him with her hammer). She seems aware of her insanity (due to a magic ring she used on herself to get Scourge's attention, but which shattered her mind as a result) yet is unconcerned with his fact, as her only focus now is Scourge.
* Max from ''ComicBook/SamAndMaxFreelancePolice'' is very comfortable with his various mental issues, which mainly include [[AttentionDeficitOohShiny the total absence of an attention span]] and [[TheSociopath being a sociopath]] (with that exact word used), but [[DependingOnTheWriter occasionally]] include nihilism, paranoia, hallucinations (both the HearingVoices kind and the visual kind, although not in combination), codependency, [[TooKinkyToTorture enjoying being hurt a suspicious amount]] - basically, he won the mental illness lottery. The other characters just accept this as part of who he is, especially Sam, and Max himself is generally upbeat and has tons of fun going on adventures, coming up with wild and wonderful ideas, and [[LawfulStupid torturing jaywalkers]].
* Ragdoll in ''ComicBook/SecretSix'', to the extent that when other lunatics join the team, he resents no longer being the craziest guy in the room.
* In a ''ComicBook/BatmanBeyond'' storyline where the future Justice League faced their equivalent of the [[MirrorUniverse Justice Lords]], this was interestingly played with by Justice Lord Flash. It was previously established that regular universe Danica Williams hears the voices of the Flashes that have entered the speed force. EvilTwin Danica is utterly contemptious of this idea, which regular Danica initially thinks is because she can't hear the voices. Evil Danica retorts that she hears ''lots'' of voices -- she assumes this is because she's crazy and her counterpart is just too weak to accept this. At the end of the story which of them was right was actually unresolved.

[[folder:Films -- Animation]]
* ''WesternAnimation/TheSimpsonsMovie'':
-->'''Scared Underling:''' Sir... I'm afraid you've gone mad with power...\\
'''[[GeneralRipper Russ Cargill:]]''' Of course I have! Have you ever tried going mad without power? It's boring. Nobody listens to ya.
* ''WesternAnimation/QuestForCamelot'' has Ruber well aware of his insanity. This is lampshaded during his song.
-->'''Lady Juliana''': [[YoureInsane You're mad!]]\\
'''Ruber''': [[InsultBackfire I'm so glad you've noticed.]] [[LampshadeHanging I've been working at it for years]].

[[folder:Films -- Live-Action]]
* Creator/MichaelKeaton, Peter Boyle, Stephen Furst and Creator/ChristopherLloyd in ''The Dream Team'' (1989).
* Mary Stuart Masterson in ''Film/BennyAndJoon''.
* In the first act of ''Film/SilenceOfTheLambs'' prequel ''Film/RedDragon'', Hannibal Lecter explains to his protege-turned-captor (Creator/EdwardNorton) that he never expected to be captured by someone less intelligent than him. Norton replies, "Well, you ''are'' insane." Hannibal [[SanityHasAdvantages politely concedes]].
* ''Film/{{Malice}}'': Jed doesn't have a God ''complex'' -- he ''is'' God!
* Kind of the entire point of the 2014 indie ''Welcome To Me'' -- Alice is stated to have a borderline personality disorder, though she [[LampshadeHanging lampshades]] the fact that her diagnosis has been reworded multiple times over the years, and her actions are primarily 'quirky,' outlandish narcissism and obsessive-compulsive behavior.
* This is one interpretation of John Nash at the end of ''Film/ABeautifulMind,'' after he comes to terms with his schizophrenia. When a man he doesn't recognize greets him at his classroom, before he addresses the man he asks a passing student to confirm that she can see him. Then he turns back and says with a smile, "Okay. I am always suspicious of new people. Now that I know you're real, who are you, and what can I do for you?"

* ''Literature/AlicesAdventuresInWonderland'' embodies (and named) this trope. Strangely enough, though, the Mad Hatter doesn't offer many lines that exemplify this as well as the Cheshire Cat does:
-->'''Alice:''' But I don't want to GoAmongMadPeople!\\
'''Cheshire Cat:''' Oh, you can't help that, we're all mad here.
* ''Literature/TheHitchhikersGuideToTheGalaxy''
** Creator/DouglasAdams' ''Literature/LifeTheUniverseAndEverything'' (the third book in the then-trilogy, but not the last, oddly enough) opens with Arthur Dent and Ford Prefect trapped on prehistoric Earth. Arthur decides to make most of their situation by going mad, but is side-tracked by Ford, who had the same idea first and now wants to tell him at length how much fun he's been having.
--->'''Ford:''' ...and then I decided I was a lemon for a couple of weeks. I kept myself amused all that time jumping in and out of a gin and tonic... I found a small lake that thought it was a gin and tonic, and jumped in and out of that. At least, I think it thought it was a gin and tonic. I may ''[grins crazily]'' have been imagining it.
** They then chase a time-travelling sofa, leading to Arthur happily reflecting on just how fast his slip into insanity was.
--->''Arthur suddenly laughed with unexpected delight. For once his day was going entirely according to plan. Not half an hour ago he had decided to go mad, and now here he was, chasing a Chesterfield sofa across the fields of prehistoric Earth.''
* Antryg Windrose, from ''Literature/TheWindroseChronicles'' by Creator/BarbaraHambly. This character -- influenced somewhat by Creator/TomBaker's [[Series/DoctorWho Doctor]] -- is very charismatically eccentric, has a reputation for being "dangerously insane", and in deep characterization confesses that he really is mad, from long years of having to sustain beliefs contrary to the reality of others around him.
* The lost explorer Gordon Willikers (get it?) from Creator/DanielPinkwater's ''The Worms of Kukumlima'' frequently discusses or makes reference to his insanity. No one questions this even though he's quite lucid and isn't a great deal more eccentric than anyone else in the book. His insanity, therefore, comes across as a mix of an InformedAbility and a RunningGag.
* In Joanne Greenberg's ''Literature/INeverPromisedYouARoseGarden'', the inmates at the psychiatric hospital have rules about such things: the disturbed ward gets to refer to themselves as "crazy", "mad", etc.; the less disturbed patients may call themselves "cuckoo" or other euphemisms. (It's an autobiographical novel, by the way: the hospital was Chestnut Lodge, a private institution in Rockville, Maryland.)
* Colonel Jax in the short story [[Creator/AlastairReynolds "Nightingale"]] freely admits that he has gone mad after [[spoiler: being turned into a living artwork representing the horror of war.]] The sentient hospital ship responsible for his fate, though, seems blissfully unaware of her insanity. (And some readers might agree that she's the sanest personality in the story....)
* ''Literature/MobyDick'': Ahab says, "They call me mad, but I'm demoniac: I am madness maddened."
* In Lisa Goldstein's ''A Mask for the General,'' a prison psychiatrist tells Layla [=MacKenzie=] that the complete economic collapse of the US drove her insane. She rejects that: "I made it [her madness] myself, like a work of art."
* In Raymond Smullyan's ''What is the Name of This Book?'' and ''The Lady or the Tiger?'', insane vampires believe they are sane but, being vampires, [[KnightsAndKnaves lie about everything they say]]. Thus, when an insane vampire says he is insane, he is unwittingly telling the truth.

* A rare serious example: Richey Edwards of Music/ManicStreetPreachers was a great user of this trope, often to devastating effect. ''The Holy Bible'', usually considered to be the band's best album and written mostly by Edwards (roughly 70 percent of the lyrics are his alone), contains a cast of Mad Hatters.

[[folder:Tabletop Games]]
* The Malkavian Clan in ''TabletopGame/VampireTheMasquerade'', and their spiritual descendants the Malkovian Bloodline in the ReBoot ''TabletopGame/VampireTheRequiem''. Although all Vampires lose their sanity over time, these guys start out full of crazy and then some. Their madness may have a mystical explanation, or it may just be the fact that since they live in a total CrapsackWorld where insanity is inevitable, you may as well skip merrily to bonkers and enjoy yourself.
** The Malkavians of ''Masquerade'' have a variety of opinions on their madness and [[MadOracle the insight it brings]]. A good chunk of the clan just views them as part and parcel of one another (heck, the clan's formal nickname is "The Clan of [[{{Lunacy}} the Moon]]"), whereas a few holdouts (such as Dr. Netchurch in the books, or Alistair Grout in [[VideoGame/VampireTheMasqueradeBloodlines Bloodlines]]) view themselves as perfectly normal individuals with keen insight into the ways of the world.
** This has led to a particularly contemptible sort of player character known as the [[http://whitewolf.wikia.com/wiki/Fishmalk fishmalk]], who is crazy in a way they think is "wacky" but all the other players think is juvenile, stupid, and distracting from the rest of the game. It is named after a bizarre picture of a Malkavian kissing a fish, check it out at that link.
* Occasionally played very darkly in ''TabletopGame/{{Warhammer 40000}}'' as a symptom of corruption by Chaos, particularly by Tzeentch.
** And by the good guys. [[StateSec Inquisitors]] and other Imperial officials occasionally muse that to the average man, doing things like blowing up your own planet to stop the enemy from claiming it, or abandoning millions to die because they aren't worth the cost of life required to save them, are unfathomably evil acts. Yet those who know the true nature of the threats facing the Imperium realize that such atrocities make a chilly sort of sense. "The very existence of the human race is the prize for victory. Our sanity is the sacrifice we make to win that laurel."
* ''TabletopGame/GeniusTheTransgression'': The good Geniuses are the ones who know they're crazy. The ''bad'' Geniuses are the ones who think they're ''totally sane''. As many disadvantages as their madness may carry, it's kind of hard not to enjoy one's madness when one can channel it into [[GadgeteerGenius physics-defying devices and gadgets]], and power them through pure crazy.
* Nearly all characters in ''TabletopGame/{{Toon}}'', with the exception of ''Crawl of Catchooloo'' characters who have been rendered sane by the [[EldritchAbomination Slurping Horrors]] (yes, ''Toon'''s SanityMeter works in ''reverse'') and the [[CulturePolice Serious Police]] in ''Toonpunk 2020½'', are crazy in a Daffy Duck/Warner Siblings sort of way, and proud of it.

* Mad Margaret from ''Theatre/{{Ruddigore}}'': "If I were not a little mad and generally silly, I would give you my advice upon the subject, willy-nilly; I would show you in a moment how to grapple with the question, and you'd really be astonished at the force of my suggestion. On the subject I will write you a most valuable letter full of excellent suggestions when I feel a little better, but at present I'm afraid I am as mad as any hatter, so I'll keep it to myself, for my opinion doesn't matter."

* Vezon from ''Toys/{{Bionicle}}'':
--> '''Vezon''':You haven't truly lived until you have seen the world through the eyes of madness. Why, half the time I don't know if what I see is what's really there, or what I wish was there ... or what I pray, I beg, I plead is not.

[[folder:Video Games]]
* ''Franchise/TheElderScrolls'' has Sheogorath, the [[OurGodsAreDifferent Daedric Prince]] of [[MadGod Madness]]. He is completely aware of how utterly mad he is, and loves every minute of it. It's rather challenging to go through the list of MadnessTropes and find something which ''doesn't'' in some way apply to him. Following the events of ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'''s ''Shivering Isles'' expansion, [[spoiler:[[PlayerCharacter the Champion of Cyrodiil]] [[AGodIsYou takes up the mantle]] of Sheogorath]].
* In the VideoGame/{{Touhou}} game ''Imperishable Night'', when CuteWitch Marisa Kirisame [[spoiler:is exposed to "pure" lunar rays, which can drive humans mad, she isn't concerned because, in her own words, "I'm insane to begin with"]]. This is the only time she comes out and says this, however.
* [[InsaneProprietor Crazy Dave]] from ''VideoGame/PlantsVsZombies'' is a good example. Why? [[CatchPhrase because he's Craaaaaaaaaaaaaaazy!]] Even further delved is the official trailer for ''VideoGame/PlantsVsZombies2'' which shows the inside of Crazy Dave's house with Newspaper Clippings stating he stopped the Zombie Invasion. So in the first game you were playing as Dave, and were actually talking to/selling things to yourself throughout the game.
* Slak the berserker in ''Videogame/DefendersQuest''. He gets much more aware of it in the NewGamePlus, at one point scolding the party for going on a trip that was his idea in the first place. They really should know better.
* The Voices of Nerat from ''VideoGame/{{Tyranny}}'' is a MindHive whose initial and dominant personality was a sadistic, paranoid psychopath, and adding progressively more and more [[YourSoulIsMine souls]] didn't help. He's also entirely aware that he is insane, joking about it in [[DidWeJustHaveTeaWithCthulhu rare "friendly" conversations]] and using it as an intimidation tactic. His deranged jests unbalance his foes and leave them [[ConfusionFu entirely uncertain what new madness the Voices will devise next]].

* Most people in ''Webcomic/{{Narbonic}}''. MadScientist is a job description, and the mads are [[ContractualGenreBlindness perfectly aware]] of the impossibility of their schemes -- leaving the sane characters chagrined when they succeed anyway. Cue great amounts of tropeplay and {{Shoutout}}s. Including the ''Alice in Wonderland'' quote, which takes on a darker meaning... [[spoiler:After all, Dave is mad!]]

** Leela in "The Sting": "Okay, I'm insane. But I'm still sane enough to know it."
** Professor Farnsworth. "I called myself mad, but I showed me!"
* Most of the WesternAnimation/LooneyTunes gang know how far out-of-kilter they are.
** This was practically Daffy Duck's catchphrase in his [[ScrewySquirrel early days]].
--->'''Random Person:''' That duck's crazy!\\
'''Daffy:''' You ain't just whistlin' Dixie! ''[maniacal laughter]''
* ''Franchise/{{Transformers}}'':
** Really freakin' creepy example: Tarantulas in ''WesternAnimation/BeastWars''. It's unclear how much of his lunacy is genuine, and it's been theorized by at least one fan that this is intentional, and he's actually the most lucid among the Predacons. Either way, the attempts at draining vital fluids of other characters, the gleeful sadism, the maniacal laughter all add up to an over-the-top loon who enjoys being an over the top loon, ''especially'' when it creeps people out... In his own words:
--->'''Tigerhawk:''' ''[shocked]'' YoureInsane\\
'''Tarantulas:''' ''[casually]'' So they say.
** ''[[WesternAnimation/TransformersAnimated Animated]]'' has Blitzwing's [[SplitPersonality "Random" personality]]. Generally much more humorous and [[{{Cloudcuckoolander}} silly]] than Tarantulas (though he's made at least one reference to cannibalism).
--->'''Blitzwing:''' ''[in reference to Megatron's plan]'' That's crazy, even for me!
** Rampage from ''WesternAnimation/BeastWars''. The quote speaks for itself:
--->'''Rampage:''' Is that fear you're feeling, Maximal? Mmm... yes. My spark, it feeds on terror. Let it grow! Let it consume your circuitry! Feel it! Yes, feel it! Feel the fear!

* ''WesternAnimation/DarkwingDuck'': PsychoElectro Megavolt gives us this gem.
-->'''Megavolt:''' They called me crazy, they called me insane, they called me loony! Boy, were they right!
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** [[{{Cloudcuckoolander}} Pinkie]] [[GenkiGirl Pie]] occasionally demonstrates awareness of her own insanity.
--->'''Twilight:''' You're a great friend. Even if we don't always understand you.\\
'''Pinkie:''' Thanks, guys. You're all great friends too. Even when ''I'' don't understand me.
** In a more villainous example, Discord: self-proclaimed Spirit of Chaos (with enough power to back it up), and completely and utterly mad. Best exemplified in his first lines:
--->'''Celestia:''' ''[about the Elements of Harmony disappearing]'' This doesn't make sense!
--->'''Discord:''' ''[{{evil laugh}}]'' Make sense? Oh, what fun is there in making sense?
* ''WesternAnimation/JackieChanAdventures'': The Monkey King, once he stops being a pest, brings out the AxCrazy and lowers [[PuppetPermutation Puppet-Jackie]] into a woodchipper.
-->'''Jade:''' You wouldn't! That's [[ForTheFunnyz not funny!]]\\
'''Monkey King:''' Haven't you noticed? I have a '''WEIRD''' sense of humour!
* Doctor Weird from ''WesternAnimation/AquaTeenHungerForce'', possibly. "It works! ''I'' am one can short of a six-pack!"
* ScrewySquirrel knows he's nuts, and ''loves'' it. (To the point where [[InsaneEqualsViolent some find him very disturbing]].)
* The early WesternAnimation/DaffyDuck-{{Expy}} version of WesternAnimation/WoodyWoodpecker used to sometimes deny his insanity even though [[IAmSong he frequently sang a theme song about how insane he was]]. Which only made him seem ''more'' insane.
-->''So I'm crazy, what what what can I do?\\
[[ParanoiaFuel So are you]]!''
* ''Franchise/EverAfterHigh'' has Madeline "Maddy" Hatter, the daughter of the man himself. She's basically her father, only female.
* Gogo Dodo from ''WesternAnimation/TinyToonAdventures''. He's so crazy that his insanity is mentioned in the ''theme song!'' Meanwhile, when he ends up in {{Wackyland}}, he sums it up perfectly:
-->'''Gogo:''' Home surreal home!
* Bill Cipher from ''WesternAnimation/GravityFalls'':
-->'''Gideon:''' You're insane!\\
'''Bill:''' Sure I am! What's your point?

%%* Truth in Television, and [[ReluctantPsycho decidedly less than fun]].
* Crispin Hellion Glover ''lives'' this trope.
* Possibly (though not necessarily) true Urban Legend. A man suffers a flat tire while driving by a mental institution one night. He removes the lug-nuts from the tire and places them in the hubcap while he puts the new tire on. A car comes by and hits the hubcap, scattering the lug-nuts, which are impossible to find in the dark. As the motorist frets an inmate from the other side of the fence points out that he can just take one nut from each of the remaining tires. The motorist is impressed, and admits that he didn't think the resident of an asylum would be so lucid. The inmate responds "I'm crazy, not stupid."
* It is a common belief among those serving in the military that special forces/special ops troops are a special kind of crazy. It's believed that, even if you're not already a few bananas short of a tree when you join up, the [[BreakTheCutie intensive training]] and/or [[ShellShockedVeteran combat experience]] will eventually push you over the edge into madness territory. Their image in entertainment very often invokes this trope, portraying them as a self-aware AxCrazy or borderline SociopathicHero; and usually an [[EmotionlessGirl emotionless]] [[TheQuietOne quiet one]], DeadpanSnarker, or obnoxious jokester fond of [[BlackComedy black]] or [[BlackComedy dead baby]] comedy. GallowsHumour is commonplace among special forces troops. This portrayal is often TruthInTelevision. The Urban Legend above is a popular [[SelfDeprecation self-deprecating]] joke among US special forces personnel.
* A possible definition of eccentricity by psychologist Dr. David Weeks goes as follows: People with a mental illness "suffer" from their behavior while eccentrics are quite happy.
** There should also be a way to take societal attitudes into account; when the people ''around'' the affected person are suffering while the person herself feels fine.
* It's been said that worrying about being insane is one of the signs of a properly-functioning mind. To put it simply: if you have to ask the question, the answer is probably 'no'. That said, there is a lot of gray area to this. Many people who really are mentally ill are aware that ''something'' is wrong. They may even know what mental illness they have and be aware that doctors have misdiagnosed them.
