->"Ladies and gentlemen, tonight I want to talk to you about the very serious problem of schizophrenia. -- '''No he doesn't!''' -- SHUT UP, LET HIM SPEAK!"
-->--'''Creator/RobinWilliams'''

In RealLife, mental illness of any kind is rarely [[DudeNotFunny a laughing matter]]. In media, however, it can be [[PlayedForLaughs played with for humor]]. When a character [[SplitPersonality swings wildly back and forth between different versions of himself]], it's almost always used this way.

It's also far too often referred to as "schizophrenia"; while the word literally means "split mind", [[ScienceMarchesOn Psychology Marches On]] and [[http://en.wikipedia.org/wiki/Schizophrenia schizophrenia]] is a complicated condition affecting perception of reality[[note]]often featuring hallucinations (usually auditory, aka. hearing voices) and delusions (often but not always paranoid). There are other aspects to it, like disordered thinking, but the losing touch with reality (psychosis) is the most important part.[[/note]], while "[[http://en.wikipedia.org/wiki/Dissociative_identity_disorder dissociative identity disorder]]" is the much rarer[[note]]there's some debate as to whether it's real or not[[/note]] condition relating to SplitPersonality.

See also TalkingToThemself, TheSchizophreniaConspiracy (a SelfDemonstratingArticle about the portrayal of the disease) and InsaneEqualsViolent, another widespread myth about psychosis.

[[folder: Anime and Manga ]]

* ''Manga/AhMyGoddess'': Urd is split into her goddess and demon selves. The attempt to reunite them results in a single Urd that switches between their personalities. The change is shown by her [[ColorCodedForYourConvenience markings changing from]] [[RedOniBlueOni blue to red]].
* In ''SayonaraZetsubouSensei'', Kaere/Kaede's split personality as a stereotypical Japanese YamatoNadeshiko and stereotypical jerkass {{Eagleland}}er is played for laughs, as is [[ThePollyanna Kafuka's]] description of previously having two split personalities who differed in respect to a slight food preference - although the latter is also a sign that Kafuka is actually [[CuteAndPsycho cute, psychotic]] and AxCrazy.
** More broadly, ''the whole class'' is some sort of crazy, and it all is played for laughs.
** Well, everyone except for Nami Hito. She's pretty normal (but [[IJustWantToBeSpecial don't tell her that]]).
* A decidedly dark take in ''Manga/AirGear'' has Agito/Akito, who swings from AxCrazy to "cute kid" depending on which side his eye patch is.

[[folder: Comics ]]

* Star Man in JusticeSocietyOfAmerica under the pen of GeoffJohns.

[[/folder]]

[[folder: Film ]]

* ''MeMyselfAndIrene'' had JimCarrey's character diagnosed with "Advanced Delusionary Schizophrenia with Involuntary Narcissistic Rage", which was really Multiple Personality Disorder that caused him to flip into his JerkAss alter-ego anytime he got angry.
** He also has moments like this in ''Film/LiarLiar'' and ''Film/TheMask''.
* ''LarsAndTheRealGirl'' takes a man who is clearly delusional and incapable of connecting comfortably with other human beings, so he buys a life-size sex doll off the Internet and appears to be convinced that she's alive.
* ''NuttyNut'' has a protagonist with a half-dozen alternate personalities, such as Tough Guy (impervious to pain and will beat you up for looking at him funny), the Clown, the Magician (who can do actual magic) and the Dog (don't... don't ask). They tend to switch with the slightest stimulus, such as someone snapping their fingers.
* ''TheNuttyProfessor'' plays it for laughs (at least the Eddie Murphy version does). In this one it's due to {{Phlebotinum}}.

[[folder: Literature ]]

* ''FelsicCurrent'''s Thendy Bravura (also known by himself and others as a dozen other names) is the embodiment of FunnySchizophrenia. We are even treated to a chapter written entirely from his point of view, complete with internal conversations and bickering between his various personalities. Although he tends to drive other characters up the wall, [[AstroTurf his antics are generally of great comedic appeal to the reader.]]
* The [[CharacterTitle eponymous]] protagonist in Geoph Essex's ''Jackrabbit Messiah'' has ''[[ShownTheirWork actual]]'' schizophrenia (not the "split personality" version), and has frequently humorous conversations with his auditory hallucinations. Sadly, though, his struggles with mental illness are [[MoodWhiplash not always so funny]].
* Completely averted in ''Sophie's Choice'', where it's revealed near the end that [[spoiler: Nathan]] has schizophrenia, which explains his delusional jealousy and erratic behaviour throughout the novel. There is no mention of having a split personality.

[[/folder]]

[[folder: Live Action TV ]]

* Averted on ''{{Dollhouse}},'' where Sierra/Priya's symptoms are much more realistic. Even though [[spoiler:she doesn't ''really'' have schizophrenia at all---her StalkerWithACrush is poisoning her with psychotic medication]].
** Played straight with Alpha. He doesn't really have schizophrenia, but two of his personalities do, and it is indeed played for black comedy.
* One episode of ''{{Becker}}'' has a very realistic schizophrenic man named Lloyd. It even includes unexciting things like flat affect and mundane examples of magical thinking. It's still played of laughs, though.
* This is supposed to be the case with ''Series/{{iCarly}}'' where the four lead characters go to a mental hospital and witness various patients' behavior. One notable example might be Sheldon Cooper laughing and screaming a TV screen with static.

[[folder: Music ]]

* There's a nameless "traditional" summer camp song mocking a huge number of occupations that can include the verse:
--> ''...A schizophrenic I would be!''\\
''No I wouldn't!''\\
''Yes, I would!''\\
''I'm not listening!''\\
''AAAAAAAAAH!''
* [[http://youtu.be/x5BZ14qlgkc "Physical Neurose"]] by Music/BuckTick. ''Slightly'' more TruthInTelevision, in that the song's lyrics are literally WordSaladHumor fused with WordSaladHorror - much like the thoughts/speech of an ''actual'' schizophrenic.
* "The Chosen" by Voltaire has "Roses are red, violets are blue. I'm schizophrenic, and I am too!"
* There's a song on Styx's ''Kilroy Was Here'' called "Double Life" with the lyrics "Nowhere to hide though we both might try, I'm schizophrenic, and so am I..."
* EmilieAutumn has a bonus track on the rerelease on ''Opheliac'' in which, among other things, she lists the mental illnesses she ''doesn't have'', obviously taking the Michael, including TourettesShitcockSyndrome, [[SuperOCD OCD (OCD, OCD, OCD)]], amnesia, and schizophrenia: she ''enjoys'' the latter, and so does she.
* "Lucky 4 You (Tonight I'm Just Me)" by [=SHeDAISY=] plays with multiple personality disorder. It goes from "you always said that I have multiple personalities" to "where'd you dig up the audacity / To ask me how we've all been doing since you broke our heart" in the first verse. It has a chorus of:
-->Number five just cries a river a minute\\
Seven wants to tie you up and drown you in it, yeah\\
Fourteen just wants to say so long, bygones\\
Thirty-two wants to do things to you that'll make you blush\\
Ten will key the El Camino that you love so much\\
And there ain't nobody wants to mess with twenty-three\\
Oh, lucky for you, tonight I'm just me
** And then just to [[CrossesTheLineTwice cross the line twice]], "It's not just up to me / I don't know, girls, what do you think?" precedes a repetition of the chorus with the group's vocals overdubbed several times.
* Flanders & Swann's "The Elephant" has these lines: "I suffer from schizophrenia/It comes on me in spells/Sometimes I'm King of Armenia/And others I'm Orson Welles!"

[[/folder]]

[[folder: Standup Comedy ]]

* The aforementioned RobinWilliams quote.
* One of Zach Galifinakis' bits include his mentioning that his sister was recently diagnosed as schizophrenic, [[DudeNotFunny which isn't funny]]. However, she once called him... and his caller ID blew up.

[[/folder]]

[[folder: Tabletop Games ]]

* This was one of the laments surrounding the [[PowerBornOfMadness Malkavians]] in ''TabletopGame/VampireTheMasquerade''. In theory, you have an entire clan of vampires whose weakness is that they pick up some form of madness, from schizophrenia to megalomania to fugue, upon Embrace (that is, if they weren't already insane before), which could be scary seeing as you have an immortal being with supernatural powers, [[MadOracle unnatural insight]], and little control over their own faculties. In reality, you have a bunch of idiots playing Malkavians who either act like children or use their insanity to commit wacky pranks (hence the [[FanNickname term]] "Fishmalk" -- Malkavians who would do something like run up to someone on the street and slap them with a fish, and call it a "prank").
** And to be fair, the game itself suggested this route in the first edition, then, when they decided that TrueArtIsAngsty, tried to turn it into the more "serious" mental problem area. Most players ignored this, and Malkavians have been a bright spot in the Old World of Darkness ever since.
* Averted in TabletopGame/{{Pathfinder}}, where various mental illnesses can affect your characters and lead to changes in their personalities; schizophrenia is one of them, and so is multiple personality disorder, but they aren't depicted as the same thing. The in-game descriptions of all these disorders are accurate and it's clear the writers [[ShownTheirWork did their research]] before including them.

[[/folder]]

[[folder: Theater ]]

* Launcelot Gobbo's [[GoodAngelBadAngel "conscience/fiend"]] monologue in ''Theatre/TheMerchantOfVenice'' is sometimes played as this.

[[/folder]]

[[folder: Video Games ]]

* In ''VideoGame/FalloutNewVegas'', almost all Nightkin have developed Schizophrenia due to constant stealthboy use. For the most point the trope is averted: the Nightkin's illness is portrayed very tragically, especially for the Courier's companions Lily and [[WoobieDestroyerOfWorlds Dog]]/[[JerkassWoobie God]]. The two times the trope's played straight is with [[BlackHumor Tabitha]], a cult leader and [[LargeHamRadio Radio DJ]], and the Brooks Tumbleweed Ranch "[[HonestJohnsDealership Wind Brahmin Salesman.]]"

[[/folder]]

[[folder: Web Comics ]]

* Part-fey characters in Webcomic/{{Footloose}} are prone to "Multiple Generic-induced Sanity Dysfunction", a form of FunnySchizophrenia that quickly become unfunny if it triggers psychotic episodes.
* In ''{{Homestuck}}'', Sollux's Funny Bipolar Syndrome is exaggerated in his [[GenerationXerox alternate universe ancestor]], Mituna, into FunnySchizophrenia resulting from a psychic MindRape. He flips wildly between [[{{Angrish}} incomprehensible rage]] and [[ExtremeDoormat excessive contrition]], although he's easily one of the most selfless and sympathetic characters in his CastHerd and bullied by his friends because of his illness, so the laughs are [[DarkComedy dark and uneasy]].

[[folder: Web Original ]]

* HarryPotty plays up Harry hearing the Basilisk to look like this in its [[Literature/HarryPotterandtheChamberofSecrets Chamber of Secrets]] spoof.
** And now the Basilisk is dead and the voice is still there...
* Vegeta from ''WebVideo/DragonBallZAbridged'', if [[spoiler:Ghost Nappa]] really is just in his head.
* Ichigo himself from ''WebVideo/OmniBleachAbridged''. It's notable that his hallucinations are always done in either real-life pictures or 3-D animation.
* LetsPlay/PewDiePie has tons of characters in many games that he interacts with as he's playing. His most famous ones are his characters from ''VideoGame/AmnesiaTheDarkDescent'', including [[CompanionCube Stephano]][[note]]a golden statuette[[/note]], [[AbhorrentAdmirer Jennifer]][[note]]a rock[[/note]], and [[ExtremeOmnisexual Piggeh]][[note]]a pig carcass[[/note]].

[[/folder]]

[[folder: Western Animation ]]

* ''TransformersAnimated'': Wreck-Gar swings between moods depending on the last suggestion he heard. Then of course, there's Blitzwing and his multiple personalities which change accordingly to the mood of his current personality (or just when it's funny):
-->'''[Angry Blitzwing]''': "The name is Blitzwing! Remember it! Because it's the last thing you'll hear before I-"\\
'''[Random Blitzwing]''': "...express my feelings in song! The itsy-bitsy spider climbed up the waterspout..."
* In ''TheSimpsons'' according to Carl, he once hired a private eye to figure out who's been cobbling his shoes for him at night. Turns out he discovered that he has severe schizophrenia. He says this as if it's not a big deal.
* Foop in ''FairlyOddParents'' is this, often getting into arguments with himself.
* In the Polish animated show ''WesternAnimation/HipHipAndHurra'', Kinga the Kangaroo [[{{Cloudcuckoolander}} owns a flower named Adelka, who only she can hear.]] Kinga not only treats her like any other person, but she appears to be her best friend.


[[/folder]]

[[folder: Other ]]

* There's a parody of the famous "Roses are red, violets are blue" poem that goes "Roses are red, violets are blue, I'm a schizophrenic, and so am I."
* A common saying found on [[FunnyTShirt FunnyT-Shirts]] is "I used to be schizophrenic, [[FalseReassurance but we're okay now]]."
