History Main / GRatedMentalIllness

** In the episode "Read It and Weep," there was a background character staying in a hospital. The fans dubbed her "Screw Loose" because she seemed to think she was a dog. [[labelnote:Note]] Actually, there is a mental illness called Clinical lycanthropy where there person does believe they're some kind of animal, dog included[[/labelnote]]

* Ripper Roo from ''Franchise/CrashBandicoot'', complete with straight jacket, while he did go to therapy, and became more sane, he returns to his straightjacket self when he gets in an explosion.

* [[IneffectualSympatheticVillain The Ice King]] of ''WesternAnimation/AdventureTime'', whose mental instability is ''[[PlayedForDrama not]]'' PlayedForLaughs. An early episode has him casually say that [[ArtifactOfDoom his crown]] makes him hallucinate all of the time, so he is unable to discriminate between the hallucinations and reality. [[WhamEpisode "Holly Jolly Secrets"]] reveals [[spoiler: he [[WasOnceAMan was once a human]], but wearing a mysterious magical crown drastically changed his [[{{Jerkass}} personality]] and got rid of most (if not all) of his prior memories of his life. He also had a fiancee; Betty, who he affectionately called his "princess", left him after he started wearing the crown. This may explain why he's [[CerebusRetcon obsessed with kidnapping princesses]]. ]] Many, after watching "[[WhamEpisode I]] [[TearJerker Remember]] [[CrowningMomentOfHeartwarming You]]", have compared [[spoiler: the relationship depicted between The Ice King and Marceline to that of someone coping with having a family member or friend with Alzheimer's Dementia. She knew him before he lost his memories and they still have an emotional connection so she is friends with him, but it breaks her heart to be around him because he doesn't remember. He's so far gone at this point that he doesn't even recognize his own name.]]

* It is safe to say that Spongebob isn't the most sane person you met; from crying uncontrollably to unstable panicking when he gets fired or is driving a car.

* ComicBook/{{Starman}} and ComicBook/TheCreeper of Creator/DCComics. SelfDemonstrating/TheJoker too, sometimes.

* Batty from ''FernGully'', due to having been experimented on by scientists.

Similiar to GRatedSex and GRatedDrug, this is when a type of insanity is represented in a child-friendly manner, such as depicting the character simply in a straitjacket or wearing a hat with a [[NapoleonDelusion big red N]] on it whilst rolling his eyes in strange directions.

* After being bitten by a particularly dangerous insect, [[MarriedWithChildren Kelly Bundy]] graduates from her normal blonde ditziness to full-blown loon. She's still generally perky and happy, just completely removed from reality.

* Ed from ''Disney/TheLionKing'' his eyes often point in different directions, his tongue is almost always hanging out, and his most of his dialogue consists of laughter (and not just because he's a hyena, because the other two are slightly more sane).

* ComicBook/{{Starman}} and ComicBook/TheCreeper of DCComics. TheJoker too, sometimes.

* Pops from ''RegularShow'' is pretty clearly off his rocker; the other residents of the park take care of him and are affectionately condescending toward his {{Cloudcuckoolander}} behavior. Leans toward AmbiguousDisorder since varying explanations have been given in-universe as to why he's like this.

* In the finale of ''{{Blackadder}} Goes Forth'', Blackadder decides that he can do a [[ObfuscatingInsanity convincing impression of insanity]] by putting underpants on his head, sticking pencils up his nose and saying "wibble." However, Melchett stated he shot an entire platoon attempting the same stunt.

* Ren from ''TheRenAndStimpyShow'' is an aversion. Despite the cartoon being aimed at kids, his manic moments weren't always PlayedForLaughs and often stepped into family unfriendly territory. For starters, the episode "Stimpy's Fan Club" contains a very long and elaborate scene of Ren rambling psychotically and considering killing Stimpy. His FreakOut in "Sven Hoek" after Sven and Stimpy wreck the house is quickly replaced with his TranquilFury accompanied by a ToThePain monologue.

* {{Lampshaded}} in an episode of ''KimPossible.'' Drakken uses his "silly hats" to make the world's most brilliant scientists turn into galloping loons. When Shego is trying to think of a word to describe it, Drakken interrupts her by suggesting the word "silly." She remarks that it is not the name she would have chosen.

* A blow to the head with a menhir has this effect on Getafix in ''{{Asterix}} and the Big Fight''.

* The original portrayal of DaffyDuck in his late 1930's-40's appearances he'd laugh constantly, his eyes would point in different directions, his tongue would sometimes hang out, and he'd click his heels together and do flips around the pond shouting "woo hoo, woo hoo, woo hoo!"

* ''[[LittleBigPlanet Little Big Planet 2]]'': During his meanie infection, Dr. Higginbotham had the habit of eating socks and trying to lick his eye balls.

* Ed from ''Disney/TheLionKing'' his eyes often point in different directions, his tongue is almost always hanging out, and his most of his dialogue consists of laughter.

* Muzzle in ''WesternAnimation/RoadRovers''.

* Happens to Alvin in ''WesternAnimation/AlvinAndTheChipmunksMeetFrankenstein'' when Dr. Frankenstein makes him drink a potion and he starts acting like a typical insane cartoon character laughing manically, his tongue hanging out, spinning eyes, and pulling pranks.

** The trope is interestingly invoked with Fred, since the character is being used to scare kids by tapping into their natural discomfort with people who are different. It turns the whole episode into something of a FamilyUnfriendlyAesop, but it ''is'' highly successful at being scary, despite the fact that he seems relatively harmless. Of course, there are [[GRatedSex other ways]] of interpreting [[AlternateCharacterInterpretation Fred's]] "naughtiness" that paint him as [[RapeIsASpecialKindOfEvil less benign]]...
