Conspiracy Theorist

""Everywhere I go there's someone in a trenchcoat staring at me, And when I'm not at home I'm sure someone's rummaging through my trash. Whatever could they want from me? Is it just a part of a giant government conspiracy? I gotta go see my doctor about this itchy pentagram-shaped rash...""

- Barenaked Ladies, "Get In Line"

Describe Write your own crazy theories about Conspiracy Theorist here.

Yeah, right. That's just what they want me to do. They want you to think I'm schizophrenic, but that's part of The Schizophrenia Conspiracy. And while I'm here explaining to you what a Conspiracy Theorist is, their Men in Black show up in their silent black helicopters. I'm not stupid enough to reveal that I know the truth about Conspiracy Theorists.

Alright, I'll tell you what. I'll give you the official line about Conspiracy Theorist; what they want you to think. And you can think about that. And, if you decide that it doesn't really make any sense, then you can go out do some digging of your own. Maybe, just maybe, you'll learn the real truth.

A Conspiracy Theorist attributes the ultimate cause of an event or chain of events (usually political, social or historical events), or the concealment of such causes from public knowledge, to a secret and often deceptive plot by a group of powerful or influential people or organizations. Many conspiracy theories state that major events in history have been dominated by conspirators who manipulate political happenings from behind the scenes. The Conspiracy is generally evil beyond evil. And yet despite how evil they are, they never betray each other, so the conspiracy stays together for thousands of years. How they accomplish this is unexplained. It is something beyond the wisdom of our puny minds.

Conspiracy theorists in the media may be associated with Right Wing Militia Fanatics, and always seem to come off as somewhat mentally unhinged (though you and I know better, right?). This seems to be the case even when one of them catches the trail of a genuine Ancient Conspiracy or Government Conspiracy. Of course, said conspiracies have a tendency to try to silence the "kook" once they learn he's on to them, despite the fact that no one would actually believe he's telling the truth. This has the effect of:
 * 1) If the attempt fails, it gives the theorist the Heroic Resolve he needs to unravel the conspiracy.
 * 2) If it succeeds, whoever investigates the murder is bound to stumble upon the conspiracy, particularly if higher-ups try to hush it up.

There is a medical condition frequently attributed to conspiracy theorists: apophenia, "the tendency to see connections where none exist" (thank you, Question). But that's only what The Man and his crony doctors will have you believe. And as Agent Mulder would say: just because you're paranoid doesn't mean They're not out to get you.

Okay. That's the official line. The rest is up to you. I've left a few clues below to follow up if you want to find the real story. Be careful. The reptilians are watching you.

To those who still just don't believe me, then wake up, smell the muffins, and get off that bandwagon! And don't you dare say those things to me!

Oh, and if you ever get the urge to buy a copy of The Catcher in The Rye, for God's sake, resist!

Anime & Manga

 * Satou's old school friend in Welcome to The NHK: "It's a conspiracy" is practically her Catch Phrase.
 * Satou himself is one of these, thanks to her influence. The title is a reference to his main conspiracy theory, that the Japanese TV channel NHK is a conspiracy to create Hikikomori.
 * Schwarzwald in The Big O.
 * Teen Genius Susumu in Wandaba Style adamantly believes that the 1969 moon landing was fake, and is thus trying to get a rocket there himself (using environmentally safe methods). In the second half of the series, his mother is introduced as a Designated Villain, simply because she wants him to admit that he is wrong (it's her methods in doing so that put her into Villain territory).
 * Neon Genesis Evangelion Gakuen Datenroku has Kensuke trade in his military fanboying for this.
 * In Full Metal Panic, Mithril has programs that troll online forums and denounce anyone who makes connections about events Mithril was involved in as a conspiracy theorist so that nobody pays any attention to the (sometimes accurate) conclusions that the posters are coming to.

Comic Books

 * Arnie Burnsteel from Scare Tactics in The DCU.
 * Rorschach from Watchmen.
 * Who started as an Expy of The Question, who in the DCAU was a saner Expy of Rorschach.
 * Cecil Holmes from PS238. Of course, in obsessing over the belief that his elementary school is a front for an alien invasion, he's completely missed out on its nature as a superhero training program.
 * Perry Noia from The Crossovers.
 * In the IDW version of G.I. Joe, Mainframe came to be regarded as a conspiracy theorist after he stumbled onto the Cobra conspiracy. He went AWOL from the Joes and started living like a stereotypical conspiracy theorist as he attempted to prove he was right.

Film
"Mother: Did you know the Deputy Director of Planning was down in Managua, Nicaragua the day before the earthquake? Crease: Now what are you saying, the C.I.A. caused the Managua earthquake?! Mother: Well, I can't prove it, but..."
 * Darren "Mother" Roskow (Dan Aykroyd) from the movie Sneakers.

"Conspiracy Brother: Let me tell you something about the word "good," brotha. Good is an ancient Anglo-Saxon word, go-od, meanin' the absence of color. I.E. it's all good, which it is, OR Good Will Huntin', meanin, "I'm Huntin' Niggas!" So when you say good morning, what you're telling me is "I'm gonna kill yo black ass, first thing in the mornin'!""
 * Jerry Fletcher (Mel Gibson) from the movie Conspiracy Theory.
 * The aptly named "Conspiracy Brother" from Undercover Brother thinks everything is out to get black people, and freaks out at even the most innocent-sounding of gestures. It takes real conspiracy theory skills to turn "Good morning!" into a two-minute paranoid manifesto.


 * At the start of the Stargate movie, Dr. Daniel Jackson is one. Specifically, he believes the pyramids were landing sites for alien spacecraft. The scientific community does not share his views and ridicule him. This is occasionally referenced in Stargate SG-1.
 * Of course, he was also right....
 * Though he doesn't believe that there's any kind of government cover-up, just that people got their facts wrong about when the Pyramids were built.
 * General Jack D. Ripper from Dr. Strangelove.
 * He believed that the fluoridation of drinking water in the 50s was a Communist plot to poison America. Believe it or not, this was an actual conspiracy theory at the time.
 * Reading between the lines, though, indicates that he came to this conclusion due to a sudden attack of impotence. So yes, the trope namer doomed the world because he couldn't comprehend that he was getting old and could no longer become erect at will.
 * Bobby Lee Swagger from Shooter. He has the 9/11 Commission report on his nightstand, and generally distrusts The Government (and for a reason). Nick Memphis also sees signs of conspiracy around the attempted presidential assassination, and gets tortured and almost "shoots himself" with the help of some Secret Agents.
 * In the '90s Disney Channel remake of the '60s comedy The Computer Wore Tennis Shoes, the main character's best friend was a stereotypical college-age radical who, in a parody of Kennedy assassination conspiracy theories, believed that President William McKinley was actually killed by his vice president, Theodore Roosevelt.
 * In the Film 8 Legged Freaks one of the Characters is a Conspiracy Theorist with his own radio station, which he uses to rant about aliens and the government.
 * Charlie's dad in So I Married an Axe Murderer is convinced that the world is run by a secret group known as "The Pentaverate:" the Queen, the Rothschilds, the Vatican, the Gettys, and Colonel Sanders "before he went tits-up."

Literature
""Haven't seen or heard a thing!" the Canadian replied. "I haven't even spotted the crew of this boat. By any chance, could they be electric too?" "Electric?" "Oh ye gods, I'm half tempted to believe it!""
 * In David Wingrove's Chung Kuo, Kim is a genius who in his teens uncovers the files showing the truth about world history, which has been falsified by the T'ang Lords
 * Luna Lovegood from the Harry Potter novels as well as her father Xenophilius Lovegood.
 * Foucault's Pendulum
 * Various characters in The Illuminatus! Trilogy, though due to the nature of the book, they're maybe the sanest people around.
 * In the Night Huntress books, Timothy, Cat's next neighbor in the first book, is convinced the government covers up evidence of the supernatural (he's right). He later goes to work for "one of those magazines that give Cat's boss headaches".
 * Several flavors of this trope (alien abductee, Satanic cult victim, militia gun nut) appear in the Repairman Jack novel Conspiracies, which is actually set at a Conspiracy Theorist convention.
 * Area 7 opens with an article from "The Conspiracy Theorist Monthly" (circulation: 157 copies) connecting a senator's death by hunting accident with the deaths of his wife and daughter by gas explosion.
 * Jonathan Shriek in Jeff VanderMeer's Shriek: An Afterword is perceived as one by the world at large because he insists that midgets who live underground secretly control the people in his home town with fungus spores. Of course everyone knows that there are midgets who live underground and really like mushrooms, but don't think that they're any more than that.
 * In Host, by Stephanie Meyer, conspiracy theorists were more likely to survive the Alien Invasion than the average person. This is because the aliens are Puppeteer Parasites and most people did not notice the difference, except the "crazies".
 * The Moon Is a Harsh Mistress included a conspiracy theorist as an aversion, as he disdains the conjecture that passes for 'theory'. Professor de la Paz pursued the study of historical conspiracies and developed a body of principles to describe how they work, how they fail to work, how they wind up being revealed. As a founding member of a revolutionary conspiracy, his theories are quite valuable for functioning in the scientific/academic meaning of the word. This also helps him develop his theory, since the most successful conspiracies are never revealed, the only way to be sure he's observing one is to take part in it.
 * After watching too much I, Claudius, Ephraim Kishon became very suspicious of his wife. Well, in one of his satirical short stories. It tends to overlap.
 * Twenty Thousand Leagues Under the Sea: Played for Laughs with Ned Land: As a professional fisher, he doesn’t believe in Sea monsters (giant narwhales or octopus), but he believes that his captors could be cannibals, that the language spoken in the Nautilus is a conspiracy to let him die of hunger (see Con Lang) and in Artificial Human:


 * In The Pale King, There's an old lady  who believes Jack Benny is attempting to achieve global thought control via radio waves. She covers her house with electrified hubcaps, which jams her neighbors' signals. She ends up getting cited for diverting her household's amperage, so she salvages a generator that runs on kerosene.
 * The Doctor Who Expanded Universe contains a novel called Who Killed Kennedy which works as a Perspective Flip on the 1970s U.N.I.T stories by presenting it from the perspective of a journalist who becomes convinced that U.N.I.T and the Doctor are part of some malevolent organisation determined to uncover the truth, and ends up ruining his reputation and becoming considered one of these.

Live-Action TV
"You call it "conspiracy". I call it "the family business"."
 * John Munch was one of these when he appeared in Homicide: Life On the Street. This was also a major aspect of his character when he moved to Law and Order SVU, to the point where a shrink accurately concluded, "You could a smell a conspiracy at a five-year-old's lemonade stand."
 * At one point he is pretending to be a homeless man and is shouting about random conspiracies. His partner just claims this is what he always says but louder.
 * Steve Crosetti was also fixated on the conspiracy to assassinate Abraham Lincoln.
 * Fox Mulder from The X-Files, a heroic conspiracy nut who is unusual both in almost always being right in his postulations about secret doings and in (usually) being a rational, shrewdly observant investigator who labors to find solid evidence to support his ideas rather than just relying on Wild Mass Guessing.
 * Also The Lone Gunmen, who got their own Too Good to Last series.
 * Ironically this has led to conspiracy theories about why it was canceled. Perhaps it was the March 2001 pilot being about an attempt by a shadowy government conspiracy to crash jet liners into the World Trade Center.
 * Hodgins on Bones. Definitely.
 * He takes it pretty hard when he misses the ancient conspiracy that has a member
 * Interestingly Hodgin's own family is wealthy and influential enough to features in the conspiracy he believes in. If anyone would know...

"Moss: Take the 1 from 1600 Pennsylvania Avenue. Split it in half. Take the two halves. Now, attach them to the two zeros. What have you got? 666 Pennsylvania Avenue. Coincidence? I don't think so. There are no coincidences, my friends!"
 * At least two such characters show up in Supernatural:
 * Ron Reznick in "Nightshifter", who is convinced that the shapeshifter attacks he's been doing independent research on are caused by "mandroids".
 * In "Slash Fiction" paranoid whackjob Frank Devereaux doesn't put much stock in magic, but he's sure that "The government's been cloning people for years."
 * Clive Finch from the Doctor Who episode "Rose".
 * Semi-subverted in that, despite sounding like an utter nutcase to anybody who doesn't know Doctor Who, he was mostly correct: he thought the pictures of the Doctor from various time periods were all the same man (they were), that the Doctor was an alien (he is), and that the Doctor is immortal (not 100% true, but 900 years is a hell of a long lifespan). The only thing he didn't guess was the time-travel angle.
 * Also LINDA from "Love & Monsters".
 * Howie in "The God Complex".
 * Stuart from M.I. High, who has failed that to notice that there is a secret government Elaborate Underground Base beneath his school.
 * Miles Goodman from Sabrina the Teenage Witch.
 * Steven Hyde from That '70s Show.
 * Frank Lapidus on Lost, who believes the wreckage of flight 815 is a fake. He is of course correct.
 * There's also a hilarious conspiracy theory video in the season 4 DVD extras.
 * Star Trek: Voyager had an episode ("The Voyager Conspiracy") where Seven of Nine goes temporarily crazy from information overload and links most of the major events of the series up to that point into a massive Federation conspiracy to capture her, a Borg Drone... this is easily dismissed until you realize that, even though her conclusion about it being all about her was flawed and delusional, several of her premises were, in fact, quite grounded and made for some tantalizingly uncomfortable questions that were completely swept under the rug by the show... One can't help but wonder if there really WAS a conspiracy going on there...
 * Voyager was a long running highly episodic series with numerous writers of various qualities. As such, it included many plot holes, logical inconsistencies and cases of characters getting the Idiot Ball. This makes it a fertile ground for any theory that could go back re-explain past problems.
 * Leverage: "Wade Perkins" (Hardison) in "The Three Days of the Hunter Job", complete with a standard-issue Room Full of Crazy. Hilariously, Eliot and Hardison start telling Parker the stuff on there is real, just to mess with her.
 * Martin Lloyd in the Stargate SG-1 episode "Point of No Return".
 * His case was a rather amusing Deconstruction, as it turns out that all his beliefs were not only correct, but he knew the truth because.
 * Sam on The West Wing has recurring run-ins with a conspiracy theorist of the "there really were aliens at Roswell and the government is covering it up" variety. He got it from his father.
 * The hostage-taker from the Criminal Minds episode "Derailed" is one of the "the government is watching me" variety.
 * Field Commander Moss of Lexx is an over-the-top parody:


 * The whole point of Conspiracy Theory with Jesse Ventura.
 * Mozzie, Neal's criminal contact, on White Collar, is incredibly paranoid and suspicious of the government, which leads to him acting out various Hollywood spy story cliches like meeting on park benches, playing loud music or running water during conversations, using code names, and so on. His antics are treated as ridiculous, but in the show's world, he may have a point.
 * Royal Canadian Air Farce had a recurring conspiracy theorist character who liked to share his theories with strangers on the street. According to him, the Kennedys were assassinated by Hitler, George W. Bush and Osama Bin Laden are brothers, bin Laden is in Canada, Eh? working at a gas station, and the Chernobyl accident happened because aliens spilled a Slurpee on the control panel.
 * In New Tricks, Brian Lane turns into one of these if he comes off his anti-depressants; most notably in one episode where the team are investigating the suspicious death of a prominent 1970s trade unionist, Brian -- himself a member of the Police Union during his service -- becomes convinced that he's being observed.
 * In the Law and Order episode "Absentia," a guru on trial for murder claims that the government is framing him ... and also that the government killed John Lennon.
 * Dudley Carew in the Midsomer Murders episode "Murder on St. Malley's Day". Amongst his theories was one that Lee Harvey Oswald was in Midsomer two weeks before Kennedy was assassinated.
 * Real Life examples of this trope are frequently given the opportunity to rant by certain programs on the History Channel.
 * The CSI episode "Leapin' Lizards" involved a group of conspiracy theorists who believed that Earth's governments were controlled by a group of shape-shifting reptilian aliens.
 * Which was based on a real case.
 * In the Community episode "Conspiracy Theories and Interior Design" Jeff is ostensibly taking a class that studies various Conspiracy Theories. The truth of the matter is quite another beast.
 * Joe Garrelli from News Radio is obsessed with conspiracies, particularly ones involving the government's cover-ups of knowledge about extraterrestrials.

Music

 * "Everything You Know Is Wrong" by Chumbawamba is a parody of this trope.

Newspaper Comics

 * Al, the bartender in Liberty Meadows, believes in numerous conspiracies, most notably that Shakespeare was actually written by Bacon.

Tabletop Games

 * The Deadlands supplement The Black Circle: Unholy Alliance had a Conspiracy Theorist archetype suitable for use as a player character.
 * In the collectible card game Illuminati, one of the groups you can control is the Conspiracy Theorists. They have zero Power (nobody believes them), but they let you hold an extra Plot card... because while they're completely wrong, they do have useful ideas. Another group, Paranoids, gives you protection against everything except Natural Disasters, because their worries are correct...
 * The Dark Mater Supplement for D20 Modern is also filled with conspiracy theories and just down right strange stories and information. Some of which is actually TRUE and caused this Troper to look up more than a theories presented.

Video Games

 * Conspiracy theorists appear in Destroy All Humans!. In the first, they are referred to as "town crazies," and suburban ones are a bit more geared towards conspiracies than others (who are sometimes just plain nuts), even catching onto the plot of the Villain Protagonist. In the second, "The Freak," a California hippy, occasionally has these moments.
 * Bosco from the Telltale Sam and Max Freelance Police games. Oddly enough, he's usually right!
 * Pretty much every character in Deus Ex, but when one considers that the conspiracies usually prove true only minutes after being first mentioned, and that just one conspiracy is nowhere near enough for this game, it's to be expected.
 * And as an added Genius Bonus for people who follow conspiracy theories, pretty much all the ones in the game are based on real-life conspiracy theories.
 * At one point, you can try explain the conspiracy you're working against to a minor character, who'll react with amusement and think you're a complete nutter.
 * The Prequel, Human Revolution, has Lazarus, a paranoid radio host convinced that FEMA are the foot-soldiers of a fear-mongering One World Order conspiracy group bent on using the augmentation debate to fulfill their nefarious schemes. Anyone who has played the original Deus Ex will be impressed with how much he got right.
 * The Truth from Grand Theft Auto San Andreas, though revealed to be much more insightful than he appears.
 * Boyd in Psychonauts is so Crazy Awesome, he invented the Milkman Conspiracy. And you get to dive into his mind...
 * Gomez, one of Deb of Night's regulars in Vampire: The Masquerade Bloodlines, comes up with increasingly bizarre conspiracy theories throughout the game... then in the final chapter, he suddenly starts citing the cosmology of the Old World of Darkness to the letter. The problem is: if that last "theory" actually precisely describes the very setting of the game, then what about the others?
 * A side quest in The Elder Scrolls IV: Oblivion concerns a wood elf named Glarthir who is convinced that several people in town are involved in a conspiracy against him, and wants the player to help him find proof.
 * Steven Heck of Alpha Protocol is a (supposed) CIA Agent/Psychopath who has knowledge of damn near every government conspiracy out there. He's actually right most of the time despite his insanity.
 * Otis Monday of Stubbs the Zombie, who mistakenly identifies a zombie invasion as a combined communist/Illuminati/New World Order/Nazi strike on his homeland.
 * Since The Conduit is a Conspiracy Kitchen Sink, it's only fitting it has its own Conspiracy Theorist, talk radio host Gordon Wells.
 * Katawa Shoujo has Kenji Setou, the main character's Bromantic Foil, who believes that Yamaku Academy is a forward staging base for a vast feminist conspiracy plotting to take over the world. The game being a romantic Visual Novel, this is (mostly, thus far) Played for Laughs in the extreme.
 * In Dragon Age 2, Cassandra (the Chantry Seeker interrogating Varric) is initially one due to her desperately seeking someone to blame for the Civil War. Deconstructed when we learn that there isn't a true Big Bad, and like in Real Life, most of the events are simply caused by a combination of coincidence and Grey and Gray Morality.
 * No-Bark is Novac's town crazy in Fallout: New Vegas. He believes a rash of ghoul attacks coming from an abandoned rocket factory are the work of "Ghosts! Commie ghosts that don't know they're dead!" Their objective: to fly to the moon, paint it pink and stick Lenin's face on it.

Web Comics

 * Sylvester from A Game of Fools.
 * According to Polk Out, there's a reason toilet paper hasn't changed since its fruition.See here.
 * In El Goonish Shive there has been a recent flood of these into Moperville after a supernatural incident during a news broadcast.
 * Deconstructed in this Exterminatus Now comic.
 * Tales From the Pit briefly features a Magic: The Gathering player who believes the New Phyrexia expansion is a hoax.
 * Homestuck: Roxy is considered one by her friends (mostly Jane) in-universe. Given that her theories include "Betty Crocker is, they're probably justified for having that opinion.
 * And it turns out that this is because
 * In Sinfest, Squidley has a fit of it.
 * In Order of the Stick Miko made huge leaps in logic and crafted a huge conspiracy pinning the blame for a horrible situation that she created on Roy and company. It's ultimately the main reason she couldn't earn redemption -- she just couldn't accept that anything was her fault.

Web Original

 * Melee's End: A prime example: Samus.
 * Illuminati and Ancient Astronauts are common themes in Doctor Steel's songs and web videos, though perhaps just for flavor. (Or are they...?)
 * FSTDT has an entire section dedicated to making fun of them.
 * Mr. Liatsis, a teacher from the V4 pregame of Survival of the Fittest, is commented on as being a notorious conspiracy theorist. Some students have their moments as well.
 * YouTube personality The Real Weekly News made a video called "Hulu Tube: Phasing You Out of YouTube." In this video, he states that the (at the time) recently added "Shows" tab on YouTube's front page was a grand conspiracy by companies like Burger King and Disney (seriously, those were his two big examples) to get all the normal content creators off of YouTube. Mentions of tin foil hats were pretty common from critics of the video.
 * Binder of Shame: Collateral Darren insists, among other things, that employers only insist on being sent resumes as part of a conspiracy to make more money for paper manufacturers, because at the interview you have to write down all the same information on a job application.
 * Mercilessly mocked in the College Humor video 'Deceptive Deceptions'. Truly something to behold: among the things "uncovered" as part of a massive conspiracy embracing all of humanity in this "truthumentary", they include the shooting of Tupac Shakur, Dan Akroyd's role in Caddyshack 2 and Nothing but Trouble, Paul McCartney's replacement by a doppelgänger, Helter Skelter possessing Charles Manson with the spirit of the Anti-Christ, Adolf Hitler actually being "a cyberganic demon" created by Nazi scientists, NASA faking the space landings, the John F Kennedy assassination, Close Encounters of the Third Kind, Dick Cheney, Nabisco, AOL, CITGO, Atkins, Adidas, the New York Knicks, Hooters, and Google. And the identity of the secret cabal that is more powerful than the American government, the Freemasons, and The Illuminati?.
 * Above Top Secret is the Wretched Hive of conspiracy message boards.
 * ATS has actually played a role in some notable conspiracy theories. Someone who called himself John Titor, posted on the site in 2000, claimed to have traveled back in time from 2036. His predictions of the USA falling to civil war and breaking into 5 subnations was memetic for a while, but disproven by 2004. Some of the first "no planes" 9/11 theories appeared on this site. Many ATS users suspected that the "no planes" theory was itself a conspiracy to make truthers proposing more rational theories look crazy by association.
 * Downplayed and lampshaded by The Nostalgia Critic when he believes the Spider-Man movies cut out a World Trade Center scene as to not offend anyone after 9/11.

Western Animation

 * The Question from Justice League Unlimited. "There was a magic bullet! It was forged by Illuminati mystics to prevent us from learning the truth!" However he is also played oddly positively for a conspiracy theorist as while his tendency to connect everything to a single overarching conspiracy (supposedly dating back at least to Ancient Egypt, and secretly controlling the world ever since) is shown to be insane it also allows him to see the connections to the real conspiracies. He's even called the League's "Data Guy" and is a case of someone being a Properly Paranoid Crazy Awesome.
 * Properly Paranoid Crazy Awesome to the point that Batman of all people calls him uptight. The rest of the JL can only give Batman dropped jaws.
 * Also, the tips at the end of shoelaces are called aglets. Their true purpose is SINISTER.
 * In his intro in the animation The Question's room aboard Watchtower is shown, with a posterboard showing an elaborate conspiracy that the Girl Scouts are behind crop circles, that the government is using boy bands to control the public, and that they are part of a single grand conspiracy with the aglets and the magic bullet. He's convinced that this all ties together somehow, but admits to not having figured out how.
 * The Boy Band one might even be a The Cuckoolander Was Right, as in the hacked file on Cadmus has a a Freeze-Frame Bonus file tiled BRAZILIANBOYZ.
 * In the same episode he comments that Supergirl eats peanut butter sandwiches. When asked if he goes through her garbage, he says one of his most memorable quotes, "Please... I go through everyone's trash."
 * Dale Gribble on King of the Hill. A believer in every conspiracy theory known, yet unable to discover that his wife had been cheating on him.
 * And when he finally realizes that the only time she could've gotten pregnant was during the time John Redcorn was visiting, he comes to the logical conclusion.
 * Bart becomes one of these (and converts most of the other kids in Springfield) in The Simpsons episode "Grandpa vs. Sexual Inadequacy".
 * And again, due to the effects of a Ritalin Expy, in "Brother's Little Helper". This time, he's right.
 * Matt Bluestone from Gargoyles, thanks to his obsession with the Illuminati (which actually does exist in the show's universe).
 * Members of "Humans Against The Extraterrestials" (from the second Teenage Mutant Ninja Turtles cartoon) believed that the aliens which had recently invaded Earth had left behind agents to infiltrate the planet, and were willing to blow up Manhattan in order to exterminate them.
 * Dib from Invader Zim.
 * Huey Freeman from The Boondocks believes that that there's a Government Conspiracy against black people from, you guessed it, the white man.
 * Adam West, as seen on Johnny Bravo.
 * Also from one episode of Family Guy. He spends $150,000 of taxpayer money to discover why his plants absorb the water he pours them.
 * Ron Stoppable from Kim Possible is like this at often times. Many of his beliefs (such as the bad guys stealing Christmas and corn dogs) are proven incorrect. However, he has been right on a few occasions, such as claiming that the lake at Camp Wannaweep was dangerous or that Lord Monty Fiske (later known as Monkey Fist) was, as he put it 'bad road'.
 * In one episode, it turns out that all the stories about Area 51 are true, leaked by the government so that people will think they're just wild conspiracy theories.
 * Dooper from Slacker Cats. He has a different theory each episode.
 * Numbuh One from Codename: Kids Next Door. Considering the world he lives in, he more often than not is Properly Paranoid.
 * Freezbone from Freefonix. Everything is either a conspiracy, or aliens.

"Remember, tin-foil hats preventing mind control is merely a lie cooked up by Reynolds Corporation in order to sell more tin-foil and fund the New World Order. But you didn't hear it from me."
