Contrary to many people's preconceptions that disabled people are all nice or otherwise pleasant to be around much like many depictions of the Magical Differently Abled Person, disability does not prevent the person with it from being an unpleasant person. Some will even use their "illness" to get away with saying things that are at best inappropriate, and at worst outright offensive.
Another variation will have the character claim to have the disability despite the lack of a professional diagnosis, or fake the symptoms so that they can get diagnosed with it. This character generally comes from a privileged background, and has thus become accustomed to treating other people poorly. Usually this character is just a Jerkass or Attention Whore, and would be exactly the same if they did not have or did not claim to have the disability. A popular subject for this over the Internet is Asperger Syndrome.note
The "faking it" variation is a parody of a similar behavior in real life, which can be a Berserk Button for people who actually are disabled, due to the prejudice they are targeted with every day compounded with having to put up with ignorant assholes who are adding insult to their injury by claiming to have it just to get attention and/or have a convenient excuse for being a jerk.
A Sub-Trope of Acquired Situational Narcissism. Arguably an in-universe example of Positive Discrimination. When a disabled character is not entirely jerkass, but just snarky, they are a Disabled Snarker. When a disabled character isn't just a jerk but also evil, then it's Evil Cripple. When a character uses their age rather than an illness to get away with similar behavior its Screw Politeness, I'm a Senior!.
There is some Truth in Television to it: a disability can have a serious impact on a person's personality traits. How much, depends on many factors: the circumstances that led to the disability, the type of life held before the accident (a bookworm may adapt to a wheelchair more easily than a sportsman), the level of support of friends and family, previous personality, etc. It goes without saying that clumsy handling of the trope can very easily result in Unfortunate Implications. Of course, No Real Life Examples, Please!
- In She-Hulk, Mallory Book uses the fact that she was left in a wheelchair as a result of one of She-Hulk's fights to justify making her day job as difficult as possible by taking on supervillains as clients, which prevents She-Hulk from representing most of her superhero friends.
- In the 1990 Paul Hogan comedy Almost An Angel, the film's hero, Terry Dean, is in a bar when he encounters Steve Garner (Elias Koteas), a wheelchair bound Jerkass who is using his disability as an excuse to push other people around. Dean calls Garner out on his behavior with a veiled hint that if Garner doesn't stop being such a jerk, Dean will beat the crap out of him. The other bar patrons object, pointing out that you can't fight a guy in a wheelchair. So Terry Dean pulls up a chair, puts it within Garner's arms-reach, and sits down in it. He then raises his fists, saying that the fight will now be fair.
- Frank from Scent of a Woman is the poster boy for this trope.
- Dwight in Scary Movie 2 takes Don't You Dare Pity Me! to such an extent that it crosses into this (albeit Played for Laughs).
- Hinted at with Melvin Udall (Jack Nicholson) in As Good as It Gets. While he doesn't claim that his Super OCD causes him to bully people with his endless pestering about how they don't live up to his (ridiculously high) standards, it's likely he has a self-serving inferiority complex that assumes that this trope will be enforced anyway because people will feel sorry for him and let his "mistakes" slide. Indeed, he is genuinely shocked when people angrily call him out for saying offensive things.
- Played with in Waiting... by an elder gentleman who gets into a discussion with Monty and the new hire about how much he enjoys being a senior because it means he can do outrageous things like Flipping the Bird at a group of schoolchildren, and as long as he smiles while doing it people assume he has Alzheimer's. Then he mentions sometimes a person will slap him and he'll realize he was flipping someone off without noticing he was doing it, so maybe he actually does have Alzheimer's.
- Batman v Superman: Dawn of Justice sees a Wayne Enterprises named Wallace Keefe, who lost his legs due to the events of Man of Steel's climax—and becoming embittered towards both Superman and Bruce Wayne, refusing disability pay from Wayne Enterprises, sending hate mail to Wayne (even saying that Wayne let his family die - despite Keefe's family being alive and well, having abandoned him), and defacing the statue of Superman by tagging it with the words "False God". Of course, how much of this is his own jerkassery or Lex Luthor messing with him is up for debate.
- The title character of Rory O'Shea Was Here is in a wheelchair and frequently tries to pick fights or break the law, knowing he won't be penalised because of his disability. This is one of many things he's called out on later in the film.
- In House Rules, Jacob is a Jerkass and considers his autism as a legitimate excuse for being such, as well as that autism is the next step in evolution.
- Averted with most of the disabled and/or Ill Girl characters in the Chalet School series, but one exception is Naomi Elton in Trials for the Chalet School. She is disabled as a result of a car accident, needing a cane to walk, and has what Elinor M. Brent-Dyer calls a 'warped personality', using her disability as an excuse to be awkward and abrasive. Of course, she gets better.
- The title character of Maurice Level's short story "The Cripple" lost the use of his hands in an accident with a grain-thresher, and receives regular compensation from a farmer who suspects him of faking the disability. On his way home after receiving a payment, he sees a girl drowning but is unable to grab her hand to save her. The end of the story reveals that he is indeed faking his disability, and let her drown to avoid giving himself away.
- The wheelchair-bound title character of German satirist Robert Gernhardt's short story Henry der Krüppel (Henry the cripple) behaves in ways that make the oh-so-politically-correct narrator cringe all the time, referring to himself and others like him as "cripples" even though the narrator insists that the term is demeaning to the disabled. When the narrator mentions Helen Keller and Frida Kahlo as inspiring examples, Henry retorts by invoking disabled Nazi war veteran Hans-Ulrich Rudel. The story plays with the trope, since most of the time Henry enjoys making the narrator (who somewhat patronizingly wants to feel better about himself by helping a disabled person) feel uncomfortable. Gernhardt got quite a bit of flak for this story - from non-disabled readers who expressed outrage on behalf of the disabled. Meanwhile he got positive reactions from disabled readers, including requests to allow them to reprint the story in their own magazines.
- In The Millennium Trilogy, Lizbeth Salander allows the Swedish government to classify her as disabled well into her twenties because it allows her to get away with less professional conduct and her legal guardian protects her from most of the annoyances that being falsely classified would bring. This backfires terribly after her legal guardian suffers a stroke and his replacement exploits her disabled status in order to force her into sex in exchange for access to her own money.
- Referenced in The Drawing of the Three: when Roland enters Detta Walker's head, she screams, causing a nearby security guard to catch her in the act of shoplifting. He goes to apprehend her, but notes that it's going to be a "shit bust" because it's "hard to convince a jury that cripples can also be slime".
- Inverted in The Curious Incident Of The Dog In The Nighttime, where Christopher's father considers his son's disability an excuse to be a jerk to him.
- Connor of Degrassi. As soon as he was diagnosed with Asperger's Syndrome (never mind that the very portrayal of the disorder was totally inaccurate,) he decided that it was okay to be a complete dick to everyone, especially his friends.
- House could be called "Disability As An Excuse for Jerkassery: The Series."
- It comes with some serious deconstruction though; although Dr. House justifies his jerkassery with his injured leg, he was a jerkass well before that. In one episode, Wilson argues against diagnosing House with Asperger's Syndrome because he'd just use it as an excuse to be an even bigger jerk (though his jerkassery often brings some humorous moments).
- One episode had a real jerkass teenager patient. After almost an hour of showing just how obnoxious this kid was, including insulting everyone, sexually harassing Cameron and even flashing her, it turns out that the kid really is sick: Iron Poisoning. His liver has difficulty processing iron properly and his mother asks House if the illness is the cause for the kid to be such a jerk. House denies it.
House: "It's not. You just raised a little jerk."
- Another episode has an 8 year old boy developing a crush on Cameron, pinching her buttocks, and then attacking Chase when Chase and Cameron share a moment together. Turns out he is sick, his aggressiveness was directly caused by having a hundred times more testosterone than normal and is key to cracking the case.
- In an episode of The Office (US), Michael suffers from a very mild burn on his foot, and ends up using a wheelchair. What's more, his constant demands distract everyone from Dwight, who is genuinely injured (he suffered a concussion when he crashed his car into a pole.)
- In a Mad About You episode, Paul & Jamie are on a "feel-good" quest. But when they watch a "feel good" movie at the theaters, they encounter a boorish Jerkass in the audience. Once Paul realized the man was disabled, he backed down, only to receive a blow to the gut. On instinct, Paul punched the man in the eye, resulting in everyone yelling at him for attacking a disabled person while the man in the wheelchair exaggerated the amount of pain he was in.
- Sugar Motta from Glee uses her (self-diagnosed, this is important) Asperger's Syndrome as an excuse to be rude to everyone. She stopped faking it after the writers got angry letters from several autistic fans.
- A combination of Sue Sylvester's protection and this trope keeps Downs Syndrome sufferer Becky Jackson from ever having to answer for her actions. Sue encourages her to take advantage of this.
- Averts this completely with Doctor Temperance Brennan's clear case of Asperger's Syndrome. She has little grasp of social cues, general etiquette and people's emotions, but if anyone points out that her actions or her words may have caused offense, she is immediately apologetic. At first, Booth doesn't seem to understand that she genuinely doesn't understand some of the basics of social interaction. However, her best friend Angela is always ready to interpret for her and her colleagues are aware of the problems she has. In later seasons, Booth begins to be able to translate between herself and strangers like the local law enforcement. She does seem to be getting better at it as she spends more time interacting with strangers and talking to a therapist.
- Her cousin, showing signs of Asperger's Syndrome that are as extreme as Brennan in the early seasons, also quickly tones down the behavior in question (citing quotes from Benjamin Franklin in response to anything and everything) as soon as somebody mentions it being an issue.
- Averted again, by season 11, Hodgins ends up in a wheelchair. He is a jerk to everyone, specially, his wife, Angela, making sure to tell everyone he is paralyzed and angry, freely being a jerk even to his boss. Several time Brennan and Cam have to put him back in line. It's not until he threatens a divorce and has a big fight with his wife, that the two finally start working in their issues. At no point, however, does anyone excuse his jackassery due to his disability.
- Dr. Romano of ER was always a jerk, but claimed he grabbed various nurses due to a malfunction of his prosthetic arm.
- George Costanza once faked a disability in order to get a number of perks at his job. He quickly began acting like an even bigger jerk than he does normally, even going so far as to have a secretary carry him to his office. The worst part is that this wasn't even really intentional on George's part. George showed up to the job interview while still recovering from injuries he received in a previous episode, and was using a cane to help him walk. His new boss just assumed he was handicapped. George was even going to correct him, but then his boss mentioned the private bathroom he'd be getting...
- In the episode "The Bubble Boy," Jerry pays a visit to a fan who has to live in a plastic bubble, but he turns out to be a jerkass who sexually harasses Susan and picks a fight with George over a game of Trivial Pursuit. But when George fights back, the neighbors are outraged: "What kind of person would hurt the Bubble Boy?". Unlike most examples, the Bubble Boy doesn't even intentionally play up his disability to get people to excuse his behavior. All he does is act like a dick and everyone gives him sympathy anyway.
- Roy (Chris O'Dowd) in The IT Crowd episode "The Work Outing" pretends to be disabled in order to cover a series of lies stemming from getting caught using the handicapped restroom at a theatrical performance. Each of his lies, however, only serves to make the situation worse for him.
- In Night Court, a recurring character, a blind woman, was bitter, irascible and mean to everyone. Because of her condition, few people call her out on this. Ironically before she lost her sight she was an even bigger jackass.
- Just Shoot Me!
- Elliot's brother Donnie faked a mental disability for twenty years just so that he could get away with mooching off the family and not have to work.
- In another episode, Maya dates a blind guy who turns out to be a jerk to everyone else. She continues dating him despite this, until he asks her to describe porn for him.
- The Lou and Andy sketches in Little Britain were built around the concept of a jerkass who is pretending to be wheelchair-bound and possibly having learning disabilities in order to both be lazy to the nth degree and get away with being demanding ("Want that one..."), contrary ("...don't like it."), and to get away with some pretty horrible and ludicrous behavior up to and including murdering a woman who wouldn't take his attitude. All this to the complete unawareness of his carer Lou Todd, a rather sweet put upon man who Andy basically treats as a slave.
- Facejacker: Dufrais, one of the personas, lives off this trope. He is in a wheelchair, but is an unpleasant, mean-spirited Jerk Ass.
- The Kids in the Hall featured Bruce McCulloch in a recurring role as an unpleasant guy who tries to elicit pity sex from women because he has a cabbage for a head (seen as cabbage leaves in place of hair).
- SCTV station manager Guy Caballero is always seen in a wheelchair, though he doesn't need it; he just uses it "to get respect."
- Saturday Night Live played a "lost ending" to It's a Wonderful Life where the townsfolk formed a mob to wreak revenge on Mr. Potter-when they find out he doesn't really need his wheelchair they get furious and really lay into him.
- Interesting note: the reason for Mr. Potter's wheelchair in the first place was that actor Lionel Barrymore needed one in real life.
- One recurring sketch near the end of MADtv featured a Jerkass mentally disabled man who constantly insulted everyone around him, but always got away with it due to his disability.
- Ana Guerrico, from Padre Coraje. Falling in love with the priest, and being told that she can't do that, does not help much...
- In The Inbetweeners, Alistair was a Jerk Ass before his kidney transplant left him in a wheelchair and his illness didn't humble him at all. It's made funnier because the people around them see him as Inspirationally Disadvantaged, which he exploits to get attention from girls.
Jay: "He's a dick! I never liked him when he was well, I never liked him when he was ill and don't like him now he's getting better... He was a complete bell-end. He was worse than Briefcase... He's not going to have got more interesting in a hospital bed attached to a drip for a year... and he used to stink."
- It's far from being the only excuse he gives, but Rimmer in Red Dwarf sometimes blames at least some of his awfulness on the fact that he suffers from the worst disability there is: he's dead.
- From the day he came out of his coma, numerous General Hospital characters have used Jason Morgan's brain damage as an excuse for his horrible behavior. To the point where his new girlfriend Robin instantly forgave him for cheating on her with Carly because he supposedly was genuinely unable to understand that it was wrong to sleep with someone else while dating her.
- Parodied on Designing Women, when Allison (played by Julia Duffy) says that she is unable not to be annoying, and a psychiatrist has diagnosed her with OPD, or "Obnoxious Personality Disorder."
- In Curb Your Enthusiasm, Michael J. Fox appears As Himself, irritating Larry but claiming it be due to Parkinson's Disease, such as shaking a can of pop and handing it to Larry.
- Law & Order: Criminal Intent episode "Silencer" has most of the hearing-impaired people featured act like this. While the one hearing-impaired person has an excuse for acting that way (his hearing sister who was supposed to take care of him ran off to live her own life and fearing that his girlfriend, who was getting a cochlear implant, would do the same, he kills her doctor), another felt her deaf newborn niece was "born right" and one Designated Hero of the school was a very antagonistic, embittered asshole who even went as far as to shoot a (hearing) woman who dared to speak with the detectives.
- One episode of Reno 911! sees Jones and Garcia forced to take a cancer patient on a ride-along. Said cancer patient insults Jones and Garcia, cheerfully discusses how his hobby of raping the female patients in his ward, and manages to convince Jones to let him hold his sidearm... and then fires it into a crowd.
- Captain Caïn from, well, Caïn was already an asshole before he ended up in a wheelchair, but now he can mock the "bipeds" around him and watch them hesitate to respond in kind to a disabled man. The few that don't hesitate get slightly more respect from him.
- The Good Wife: Recurring antagonist Lucas Canning is a lawyer with tardive diskinesia incurred as a side effect of medicine, and invariably plays up his disability in court to elicit jury sympathy. The big joke being, his professional specialty is defending corporations from class-actions over the very type of wrongdoing from which he incurred his disability in the first place. Lampshaded in one incident where he tried it on a wheelchair-bound judge in conference; the judge basically went, "Yeah, I'm a paraplegic, so what? Knock it off and present your case."
- Alison Sugarbaker of Designing Women uses her Obnoxious Personality Disorder to excuse her being a total cow.
- In Late 2006, Eugene (whom is portrayed as a wrestler with Special Needs) had a VERY brief Heel Run. After turning on and defeating "Hacksaw" Jim Duggan, Eugene would then shout "I'M SPECIAL!!" His "I'm Special" gimmick would return the week after when he attacked Val Venis when he was hosting the Kiss Cam. Afterwards the turn was quickly forgotten, and Eugene returned to his Face Routes the following month.
- Harry in Nebulous has been severely injured by the protagonist, Nebulous, and has been left a Davros-style mad scientist on a life support system with an electronic voicebox that has No Indoor Voice. He constantly reminds the protagonist about how his entire existence is agony while describing increasingly horrific medical problems caused by his cybernetic parts in his shouty electronic voice, but he's honestly more sympathetic than Nebulous is.
- In his special Voice in my Head, Christopher Titus talks about his friend and fellow comic Michael Aronin, who suffers from cerebral palsy and one time turned up the disability "3000%"note in response to a waitress who thought Disabled Means Helpless.
Titus: Mike, dead serious, "That bitch deserved it."Titus: I see Satan flash across Mike's face, and my first thought is "You don't deserve better parking, because you're an evil prick."
- Something*Positive: As a young boy, Fred was admitted to a hospital for an ear infection, where he was antagonized at every turn by a boy in a wheelchair, who used his disability as an excuse to rage at the world, and every other child at the hospital hates him. Eventually, Fred and his friends team up to scare him and teach him a lesson... whereupon it is revealed that the boy is in the hospital for a heart condition, and the shock of the scare ends up killing him.
- Mituna, Sollux's Dancestor in Homestuck, tends to burst out into profanity and Anti-Seadweller Slurs frequently. However, this is because he suffers from severe brain damage that has left him with a split personality and intellectual disability, compounded by several speech impediments and a particularly frustrating typing quirk. As a result, most people don't take his outburst too seriously.
- Terezi's blindness has never stopped her, but she does use her disability as an excuse to troll people for inadvertently using vision-based metaphors.
- According to Saturday Morning Breakfast Cereal, this is called "Assburger's Syndrome".
- Mike in Shortpacked! demonstrates the best way of dealing such a person.
- An episode of The Bedfellows, appropriately titled "Aspergers," has Sheen's erratic, antisocial behavior diagnosed as the titular illness. Sheen, being Sheen, proceeds to rampage out of his doctor's office office, speed through traffic, shove his way to the front of a prescription line and eventually resist arrest for all of it by shouting "I HAVE ASPERGERS!" over and over the whole time. It turns out he doesn't have the disorder at all. He's just a jerk.
- Subverted in Archer. When the titular character finds out he has cancer he takes advantage of everyone's good nature (such as taking his valet's holiday and convincing Lana to sleep with him again). Once he's indulged, Archer changes his tune and tries being nicer to all the people he knows, even claiming that he probably deserved cancer after being such a dick his whole life.
- Family Guy: Peter uses his diagnosis of being intellectually disabled to be even more of an asshole than usual, being abusive to people, shoving to front of lines, and just generally misbehaving all with a "sorry, retarded". Deconstructed when his ridiculous behavior causes child services to take the kids away because he seems too unstable and dangerous to care for them.
- In a later episode, Chris goes on a date with a girl with Down Syndrome, who ends up treating him pretty awfully. Finally fed up with the abuse, Chris comments that he thought people with learning disorders were different and nicer than other people, but now realises that they can be just as mean and selfish as everybody else, and they break up.
- Inverted with Joe, who is paralyzed from the waist down but generally outgoing and friendly. In one episode where Joe regains the ability to walk, NOT being disabled makes Joe shun his friends and his wife in favour of a set of new friends. It isn't until Joe gets crippled again that he is brought back down to humble levels.
- In The Proud Family, Valentine's Day Episode, Penny dates Johnny, a wheelchair-bound boy, who seems angelic at first, but turns out to be a rude prick who uses his disability to get his way. When Penny finally tells him off for his behavior and breaks up with him, her parents tell her that they're proud of her for standing up for herself and their family.
- In South Park, Eric Cartman has done this a few times:
- In "Le Petit Tourette", he claimed to have Tourettes so that he could get away with making racial slurs and insulting people. This is only assisted by the self-righteousness of a Tourettes' spokesman, who interprets every suspicion about Cartman as malicious bullying. He's eventually hoisted by his own petard, though, as his ability to self-censor disappears, meaning his outbursts reveal some very embarrassing things about himself.
- In the episode "Ass Burgers" he attempted to do this with Asperger's Syndrome, but failed due to a very basic misunderstanding of the condition (he thought it meant that burgers come out of his ass).
- In "Buddha Box", he gets diagnosed with anxiety, which he uses as an excuse to spend all day on his phone while wearing the titular Buddha Box (a box worn over the head with a monitor inside, allowing a person to use their phone without any distractions). Whenever someone calls him out for using his phone while wearing a box on his head in inappropriate situations (like at school, or at a water park), he immediately bursts into a rant, screaming about how he's being mistreated for his anxiety, how his anxiety makes it hard for him to express himself, and how everyone has anxiety. That last point ends up working a bit too well, and by the end of the episode everyone in town has used that argument to self-diagnose with anxiety and wear the Buddha Box (except for PC Principal and Strong Woman, who take advantage of everyone's distraction to finally act as parents for their PC Babies without fear of being judged).
