Taught by Television

"''In the Mushroom Kingdom

''I'm the finest Doc by far

''I got my degree by watching

House and Scrubs and ER"

""Since TV didn't lie (well, not usually) (okay, very often) (especially during commercials) it had to work!""

- Sailor Nothing

Some people learn by staring at text. Some people learn through trial and error. And then there are those who just have to watch television...

A character who you wouldn't normally expect to be a source of knowledge reveals, often in excruciating detail, important facts that help your group achieve their aims. Perhaps he can identify lethal plants in the the wild, or can tell an odd symptom of disease that throws light on a murder mystery. Everyone's impressed, but skeptical of where he gained this new-found logic.

Easy: he saw it on Discovery Channel once.

A common way to add information to a scene, while letting the designated idiot play The Smart Guy for a change. Plus it delivers the important message that watching TV is good. It's not always documentaries, of course, and they can still make mistakes if they copy near realistic TV shows, such as CSI, when they aren't as realistic as they appear.

Naturally, this is Truth in Television, in more ways than one.

In the event that the character learned what they know from television through repetition, see Saw Star Wars 27 Times.

Anime & Manga

 * Case Closed / Detective Conan
 * This is Jimmy Kudo's favorite explanation for how his alter ego Conan Edogawa knows things that no six-year-old should. Of course, he's lying.
 * Even Ai Haibara, the local Kuudere, also pulled a Taught by Television Justification after she Character Filibuster about the hereditary nature of the Japanese upper class. Of course, she's also lying.
 * The heroine of Fushigi Yugi avows a love of satellite puroresu broadcasts just before unleashing the Wrestler in All of Us on an entire street gang. Though while she's bragging, a straggler manages to immobilize her by the ankle long enough for them to get back up and dogpile her.
 * Codename Sailor V, the manga that Sailor Moon is a sequel to, has Artemis being impressed with Minako knowing something about Greek Mythology until he finds out she learned it from a Video Game.

Comicbooks

 * In Creature Tech, after Dr. Ong gets an alien symbiont attached to him, he falls asleep watching an old kung-fu film--while the symbiont stays awake for the entire thing. The next time Ong finds himself in a fight, the symbiont takes control of his body and uses the the moves from the film to open a can of kung-fu whoopass.

Fanfiction

 * In Hogyoku Ex Machina, Ishida lists off several medications for tuberculosis off the top of his head. When everyone turns and looks at him funny, he says he learned them from an episode of House.

Films -- Live-Action
"Dae-Su Oh: The TV is both a clock and a calendar. It's your school, your home, your church, your friend... and your lover. But... my lover's song is too short."
 * Dude Where's My Car The pair is saved from the mad French Ostrich farmer because on of the guys saw a documentary on ostriches on Animal Planet. The question the farmer asked was a homage to Monty Python and The Holy Grail.
 * Perhaps a more literal example: Jim Carrey's character in The Cable Guy is a man whose mother was a prostitute who was never around to teach him anything, and as a result he learned everything he ever knew from television in general (and sitcoms in particular). The plot revolves his brutally extreme measures to keep his life working exactly as he thinks it should be, following literal TV Tropes, even at the expense of others' safety and privacy.
 * Oldboy.


 * An inversion forms the basic plot of Galaxy Quest: aliens intercepted the broadcast signal for a really cheesy sci-fi TV show, thought it was real, and based their (actually real) military on this "documentary." Also played straight when
 * In Chocolate Fighter, an autistic girl becomes an invincible fighter from watching years of Thai television.
 * Splash: Madison learns to speak English after watching television for a whole day.
 * At multiple points in Big Trouble, one of the two FBI agents comes up with totally obscure information about the topic at hand. When everyone else in the scene looks at him in amazement, he shrugs and says either "Discovery Channel" or "Travel Channel". Justified because it was implied that the agents spent a lot of time in hotel rooms with nothing else to do except watch television.

Literature
""Do you just hate trash cans?!""
 * Animorphs
 * There was a book where Rachel knows something about volcanoes. Everyone stares, and she explains that she saw an episode of The Magic School Bus. She was somewhat embarrassed about that.
 * And then there was the time Marco drove a tank... using his Playstation experience. And knew he could drive off a flatbed car onto the (raised) ground alongside the tracks because he saw it on the Discovery channel. Lampshaded by Tobias: "Ah. Video games and cable. How reassuring." To be fair, his skill at driving is about as good as you'd expect someone taught by video games to be.


 * In the Maximum Ride series, the first book explains how the protagonists can function normally in a human society after spending their childhood being treated like animals - to the point of sleeping in dog crates - by... saying that they watched a lot of TV in the two years since they escaped the laboratory where they were imprisoned. Uh, okay.

Live-Action TV

 * In Friends, Joey knew how to deal with a jellyfish sting (you pee on it) because he saw it on the Discovery Channel. This is an example of such information being wrong (whether on the part of Discovery Channel or Friends). Urine actually makes jellyfish stings worse.
 * Nick in CSI knew something obscure and was annoyed that everyone assumed he only knew it from TV, whereas if it had been Grissom, they'd have thought he'd read it in a book. Even though he actually had seen it on Discovery.
 * In the House episode "Frozen", Kal Penn's character explains his knowledge of Antarctic ice-breaking equipment this way.
 * Scrubs
 * There was an episode where J.D. diagnosed a patient with Necrotizing Fasciitis based on a documentary he'd seen the night before. Cox mocked him, but he turned out to be right.
 * In another episode, Cox gets annoyed with the new interns for getting their information from House. See the Real Life section.
 * Subverted hilariously in the Cousin Skeeter TV movie New Kids on the Planet, where Skeeter tries to show of his "Kung Fu Skills" from watching tons of martial films to aliens. The aliens then pulled an Indian Jones, and just shot near him. Skeeter surrenders immediately.
 * However, Bobby did manage to fly a NASA rocket ship thanks to a flight simulator video game.
 * In an episode of Dirty Jobs, Mike Rowe rattled off some trivial knowledge about farm animals, then pointed to his temple and said "Discovery Channel." Clearly, even Discovery Channel hosts can learn from the Discovery Channel.
 * Keith Miller from Eastenders embodies this trope. This is a case of the actor adding a little of themselves to their character. David Spinx is well known to compete in Pub Quizzes at his local, so naturally his head will be filled with random knowledge.
 * In My Family, a Charity store owner identifies a highly valuable teddy bear because "we all watch Antiques road show".
 * In Masked Rider, Albee and Molly tell Dex to learn how to talk like a human from watching television- which he does all night. The trope ends up being subverted-Dex instead memorises tv commercials!
 * Rose on The Golden Girls stuns everyone by correctly answering a Trivial Pursuit question about Mozart's "Eine Kleine Nachtmusik." She explains that she learned it from watching Bugs Bunny cartoons.
 * Ned the piemaker from Pushing Daisies is capable of competently fending off a skilled swordsman due to his childhood desire to be a Jedi.
 * A character on Heroes actually has this as her power -- anything she saw on TV, she would instantly be able to do perfectly.
 * Sawyer from Lost claimed that anyone who watches TV knows how to improvise a slow fuse with a cigarette.

Video Games

 * Travis Touchdown in No More Heroes learns new wrestling moves by watching old videos.

Web Comics

 * Subverted in Melonpool: at one point the crew encounter a giant space amoeba. At first they relax thinking Mayberry knows what to do, since he is a Star Trek fanatic and can simply do what the Enterprise crew did when they encountered such an amoeba in "The Immunity Syndrome"... however one of the comic's running gags is the fact that Mayberry has seen all episodes of the Original Series... EXCEPT "the one with the giant space amoeba" and is eternally prevented from doing so.
 * In Homestuck, Karkat's interest in romantic comedy films earns him some mockery from his friends, but also gives him insight into troll psychology and romance that none of his peers could match. When other trolls need advice regarding their love life, Karkat is almost invariably the one they go to.
 * The Whiteboard: Sandy, who had no prior experience with paintballing, is shown repairing a marker at Doc's shop after months of reading the shop's e-mail, and says she figures she could probably build a whole nuclear reactor because of that experience.

Web Animation
"''In the Mushroom Kingdom, I'm the finest doc by far
 * Dr. Mario with Lyrics by DarqV and Brental Floss:]]

I got my degree by watching House and Scrubs and ''E.R."


 * You can't learn surgery from television, you might think you know it all...

Web Original

 * Gordon Freeman in Freemans Mind admits that his knowledge of guns stems from watching Die Hard fifty times. Surprisingly, he's actually a very good shot.
 * In his very first Terror T.R.A.X playthrough, Spoony assured his audience of his paranormal detective credentials: namely, that he's seen every episode of The X Files, Kolchak the Night Stalker, and Angel.

Western Animation

 * The Simpsons
 * Lisa claims that this is how she knows about hermit crabs' shells to a bunch of kids in one episode.
 * Bart hides from a Shelbyville gang in the tiger-handler area of the zoo (It Makes Sense in Context) and finds a note that the only way out (i.e. without any tigers) is door number 7, only the doors are labeled with roman numerals, which Bart doesn't know. Until he remembers the Rocky sequels and pieces it together just in time. The real joke there, though, was that they had studied roman numerals in his class, that same day (a.k.a. earlier in the episode), but he didn't pay attention.
 * Futurama
 * In one episode, the shrunken-down cast flies through Fry's nose. Dr. Zoidberg points out a nasal capillary they can fly through, and Hermes asks how he knew about that, as Zoidberg generally knows nothing of human anatomy. Zoidberg mentions his medical training, but admits that this he learned from a commercial for allergy medicine.
 * Fry has several moments where he tries to solve problems that he watched on TV. He tries to figure out how to fake being the boyfriend of Amy and Leela at the same time by watching Threes Company and uses TV clichés in the reinactment of the last episode of Single Female Lawyer to prevent Aliens from destroying mankind because they couldn't watch said episode.
 * A variation of this is used in Duck Dodgers, "The Queen is Wild", wherein Dodgers claims to have "learned all [his] hard sciences from reading comic books". The scary thing: His idea worked.
 * During the episode "The Ci-Kat-A" on Swat Kats, Razor seemed to know exactly what the alien bug monster was going to eat and where it was going to go. When T-Bone asked him how he knew all that stuff, Razor replied: "Horror movies, where else?"
 * Averted in a episode of Pinky and The Brain, where the Brain realizes too late that Pinky had the answer to a TV trivia question he needs to win a game show, after he has already knocked Pinky out for being annoying. Which is, of course, a reference to The Honeymooners.
 * Played straight in another episode where the two find themselves on an alien ship. Pinky knows how to pilot it due to it being identical to the one shown in "The Z Files", which Brain had earlier berated Pinky for wasting time with.
 * On The Fairly Odd Parents, Poof learns kung fu from television.
 * In the storybook Time Out!, Timmy is able to answer a teeth-themed riddle thanks to his favorite episode of a TV show he watches.
 * In American Dad, Roger wants to become a police officer: "Do you know how many Police Academy movies I watched in preparation for this? NONE, because I knew it would only give me bad habits!"

Real Life

 * CPR was a fairly rare skill set and not commonly taught to the general public until emergency workers started seeing it being used in the 1970s by civilians (mostly wrongly, but they had the basic concept) with no training. They'd seen it being used, and knew what it was for, on Emergency!
 * Medicine students often learn a lot about diagnosing patients by watching House MD. To the show's credit, it raises awareness about rare conditions that are often under-diagnosed or missed by younger doctors who have no personal experience with that particular condition. The show has also helped raise Lupus awareness, which is good news for Lupus patients in general.
 * Regardless of how silly the diagnoses of the show are, the form of diagnosis that House employs isn't unsound. Med students wouldn't be learning to see rare diseases in every case, they'd be learning to watch for little details, not to take everything a patient says at face value, and to consider symptoms that might not be seen as symptoms. All of this is a good thing if it helps prevent someone from being misdiagnosed.
 * The Real Life Joseph Bell had advocated using small clues, sometimes observing callouses on a patient's hand to determine their occupation. His methods where often the best at diagnosing a patient, and he may be seen as a Real Life version Dr. House. Note that Dr. Bell was the inspiration for Sherlock Holmes, and the character of House is based off Sherlock Holmes in many ways.
 * One teaching doctor would record episodes of Casualty, label them by injury and use the make-up work to show his students what the injuries looked like.
 * Ken Jennings, who won 75 games of Jeopardy in 2004, admitted on Television Without Pity that he'd correctly answered a question about the Olmecs thanks to an episode of The Simpsons.
 * A mother reportedly saved herself and her son after their car dove into the drink by following the advice she saw on Myth Busters.
 * An 8-year old kid saved his 5-year old neighbor from drowning in a nearby lake using lifeguard swimming moves he saw on an episode of Spongebob SquarePants.
 * From 1989 to 1996, Rescue 911 was responsible for having many lives saved by people who saw the show. In fact, the show aired two episodes, called "100 Lives Saved" and "200 Lives Saved," showcasing stories of people who saved lives thanks to what they saw on Rescue 911.
 * Episode 5 of Season 6 of Canadas Worst Driver had a guest appearance by a viewer who escaped a dangerous situation using the Swerve-and-Avoid technique taught on the show.
 * On at least one occasion, a elementary-school child has saved a friend by using the Heimlich Maneuver. Which they learned, it should be noted, by watching The Simpsons.
 * This is supposed to be the purpose of Baby Einstein videos. Although, at least one study showed that they had the opposite effect.
 * Beginning in the Nineties, school systems in America began to really tighten in on Math and Sciences, usually coming at the expense of other subjects. For a lot of kids, their only really in depth knowledge of History, Geography, and the arts likely came from an Edutainment Show such as Where in The World Is Carmen San Diego or Young Indiana Jones.
 * Some people often watch a foreign language TV program like a telenovela and overtime end up speaking in that language, e.g. Spanish.
