->''You know you're not supposed to go in there. What is your fascination with my Forbidden Closet of Mystery?''
-->-- '''Chief Wiggum''', ''WesternAnimation/TheSimpsons''

There are two closed doors right next to each other, identical in every way except one: One has a large KEEP OUT sign on it in bold, red letters. [[SchmuckBait Which door is someone more likely to try to open]]? It's not rocket science.

Forbidden Fruit is a person, place, or thing absolutely irresistible to one or more characters, whose appeal lies solely in the fact it has been [[DepartmentOfRedundancyDepartment forbidden, prohibited, and declared unquestionably off limits]]. They feel they must have it only because they know they can't or shouldn't have it. Frequently takes the form of a [[SealedEvilInACan Pandora's Box]] you are not to open, a BigRedButton you are not to press, an experiment you are not to mess with, a person you are not allowed to be with, or [[TurnOutLikeHisFather even hear about]], a potion you are not to taste under any circumstances, or [[ForbiddenZone a place nobody is supposed to ever visit]].

Can be a result of GenreBlindness, but not usually, since the attraction of Forbidden Fruit is in and of itself [[SchmuckBait contrary to logic]]. More often than not, the characters ''know'' that going for it would be a stupid move; they just can't help themselves. (They are particularly likely [[YouthIsWastedOnTheDumb to be young]].)

Needless to say, opening the forbidden door or acquiring the Forbidden Fruit leads to disaster 99.9% of the time. Used often in setting {{Booby Trap}}s, where it becomes SchmuckBait, when a villain intentionally takes advantage of the power of Forbidden Fruit to lure heroes to their doom. (Unless, of course, he is redeemed by the power of DeliciousFruitPies.)

Can also be seen in {{shipping}}; people like pairings with DefectingForLove, HoYay, incest, etc. ''because'' it breaks taboo.

The trope takes its name from the Bible, where Eve is tempted into eating the Forbidden Fruit (an [[HowDoYouLikeThemApples apple]], according to {{Fanon}}), making this OlderThanFeudalism. (It is also theorized that the "forbidden fruit" of the Bible was actually a fig or a pomegranate, the forbidden Underworld food that did in Persephone, but that's another tale.)

In his analysis of the FairyTale, ''The Morphology of the Folktale'', Vladimir Propp concluded that the functions "prohibition" and "disobedience" really formed a single plot function -- any prohibition was bound to be violated.

[[http://en.wikipedia.org/wiki/Scarcity#Scarcity_in_Economics The economic principles of scarcity]] may go a long way towards explaining this phenomenon.

[[folder: Anime and Manga ]]
* ''Manga/AhMyGoddess'' has a human example, where ultra-popular 'School Queen' Sayoko's interest in Keichii originally stemmed from his complete disinterest in her.
** This is how Skuld got "impregnated" with her angel.
** In one of the ''Manga/AhMyGoddess'' "Mini-Goddesses" adventures, Skuld labels a BigRedButton "Do Not Touch," and naturally Gan-chan and Urd fight over who will press it first. Skuld wisely re-labels it "Please Touch Me," causing them to lose interest -- at which point the ever-obliging Belldandy pushes the button.
** Aoshima is implied to lust after Belldandy because of this trope.
* In episode 57 of ''KeroroGunsou'', Viper the Elder captures Kururu with a trap hidden in a box marked "Don't you dare open this!" As he goes to open the box, Kururu even remarks "That just makes me want to open it even more."
* The sealed door at the Fuuka Shrine in ''Anime/{{Mai-HiME}}'', episode 6. Mai and her friends are warned ahead of time by Shiho's grandfather never to open it, out of fear of unleashing a great evil. Midori, who had been sneaking around the place all day playing AdventurerArchaeologist, gets locked inside the shrine with seemingly no way out. She didn't hear the warning. Guess what happens next.
* In ''MamotteShugogetten'', one of Shaorin's previous masters was a little girl. When she wanted to go to the town near their house, Shaorin told her absolutely no, because the wolves were near it. Shaorin later goes to town herself, leaving the girl all alone. The instant Shaorin leaves, the little girl leaves as well. This leads to the girl being fatally injured by the wolves and dying in Shaorin's arms.
* ''{{Naruto}}'' has [[spoiler: a literal Forbidden Fruit from a tree in the backstory. During an era of war, a princess ate the fruit of the God Tree to gain its power to end the conflicts by force. Her son was born with similar powers, the Sage of the Six Paths. The Tree became enraged by this, turning into the [[EldritchAbomination Ten Tails]].]] The rest is history.
** It is later revealed that [[spoiler:the Tree never reacted to the theft of the fruit. It was Princess Kaguya who became corrupted by her power, then, in anger of her sons inheriting it, absorbed the rest of the Tree and mutated into the Ten Tails in an attempt to overpower them and reclaim the power she felt was rightfully hers.]]
* Implied in ''OnePiece'' with Boa Hancock. She's declared the "most beautiful woman in the world," and can mesmerize and have pretty much ''any'' man she wants. Guess who she ends up falling for? Luffy, the ChasteHero who will [[NoHuggingNoKissing absolutely never return her feelings]]. It's even implied that she fell for him ''because'' he was "not like the others," with him calling her a "stupid lady" and telling her to shut up.
** In a more literal example, the Devil Fruits, which give the eaters superpowers but make them unable to swim, even taking away their buoyancy. And due to the fact that that world is mostly water, it's a heavy price to pay for anyone who would be a major part of the plot; pirates who eat it (including Luffy, the protagonist) are willingly risking their lives.
* Arguably, any person who wants Sousuke from ''LightNovel/FullMetalPanic''. Which is [[EvenTheGuysWantHim a lot of people]]. Pretty much every one of them ''knows'' that it's [[TheStoic near impossible]] for him to [[ChasteHero ever return their feelings]]. And although each one of them normally has another person who is in love with them, they can't seem to help but be drawn to the mysterious and unattainable Sousuke. It came as a huge shock to most characters that he started to have some reciprocating feelings towards Kaname - something even ''she'' didn't know or expect (as she herself even thought that having feelings for him is hopeless, but it's something she just can't help).
** Especially noticeable with [[StalkerWithACrush Gauron]], who actually had [[WifeHusbandry two beautiful girls]] who were desperately in love with him, and [[LoveMartyr whose existence revolved around him]]. Did he care? No. He just can't seem to forget that [[{{Shotacon}} beautiful and emotionless boy]] he saw [[LoveAtFirstSight once upon a time]], who currently hates him with a passion and loves to beat the shit out of him.
* The chosen priestesses in ''FushigiYuugi'' must be virgins and remain as such until they summon the deity that chose them and ask for three wishes. Cue excessive amounts of [[AttemptedRape rape attempts on the heroine,]] {{Melodrama}} between love interests, and [[RapeAsDrama the like.]]
** This is taken even further when, [[spoiler:in the prequel manga, during the time of the priestesses of Genbu and Byakko, it's revealed that a wish for the priestess to be with a man she loves in the world of the Universe of the Four Gods cannot ''ever'' come true. The Priestess of Byakko, Suzuno, requests this wish, and Byakko cannot grant it to her.]]
* ''SakuraGari'': The one person Souma finds himself truly falling in love with is the only person who has absolutely no interest in him. As a matter of fact, it's addressed that the main reason he fell in love with Masataka was because Masataka was "different from the others." And Souma, of course, unaccustomed to not getting sex from someone he wants, [[spoiler: proceeds to tie Masataka up and rape him repeatedly]].
* In ''Manga/FullmetalAlchemist'', knowledge of the Philosopher's Stone is kept under wraps by the government, seeing how [[spoiler:[[HumanResources it's made out of people]].]]
** In [[Anime/FullmetalAlchemist the 2003 anime adaptation]], knowledge of stone is intentionally banned and repressed because [[spoiler:the BigBad knows it will make the truly desperate keep chasing the legend until they figure out how to make it -- [[HumanResources and subsequently won't back out when they figure out it's people]].]]
* ''Manga/ACruelGodReigns'': Ian falls for Jeremy, and seems to love him in a deeper way than anyone else he's been with over the course of the series, but not only is he his stepbrother, but he also killed his father and albeit accidentally, his stepmother.
* [[TheBeautifulElite Iason]] [[ArtificialHuman Mink]] of ''LightNovel/AiNoKusabi'' had this in spades for his human SexSlave Riki that he was forbidden to sleep with as an Elite due in part to CuriosityIsACrapshoot. This unfortunately leads to [[spoiler:DeathBySex]] and [[spoiler:CuriosityKilledTheCast]].

* Rogue of the ''Comicbook/{{X-Men}}''. Her mutant powers keep her from touching others or else they will be rendered comatose. Gambit, [[TheCasanova relentless and successful womanizer]], finds himself stuck on the notion of a woman that even he can't have. (It helps that, like most of the women in the Marvel universe, she's gorgeous.)
* ''ComicBook/MyLittlePonyMicroSeries'': Jade's office which she makes '''very''' clear to Twilight not to enter. Naturally Twilight can't help but sneak a peek when Jade goes off to run an errand.
* ''Defied'' in one ''FoxTrot'' comic. The first panel shows the door to Jason's room, with a sign saying "Keep Out!" with a skull and crossbones on it. The next panel shows a sign added with an even graver warning, the third panel a third sign with an even graver one. The fourth panel shows Jason inside his room, sulking (with a bucket of water balanced on top of the door), saying, "Reverse psychology is overrated." (Of course, it's ''very'' likely that his siblings are simply wise to his tricks.)
* A ''NewspaperComics/NonSequitur'' strip shows a man in a hotel lobby looking at a sign that says, "Absolutely NO rhinoceroses allowed!!" The caption reads, "How to get everyone to suddenly want to own a rhinoceros."
* A seedy pimp in ''ComicBooks/{{Transmetropolitan}}'' pointed out that he pimps retards and other "naughty" girls because it's what his clients want. "If it ain't kind of creepy and dirty and mysterious and forbidden, guys don't get off."

* "Literature/{{Tatterhood}}" forbids her family to watch while she fights witches and trolls; when her sister does, her head is turned to a calf's head. Not to mention Tatterhood's existence came about because her mother ate something she was forbidden to.
* Though it is very prevalent in fairy tales -- still, there are also a multitude of fairy tales aversions, a small sample of which: "Literature/{{Bearskin}}", "Literature/TheGingerbreadMan", "Literature/TheRoseTree", "Literature/TheThreeAunts", and "[[http://www.surlalunefairytales.com/authors/grimms/14threespinningwomen.html The Three Spinners]]".

* In ''Disney/BeautyAndTheBeast'', the Beast tells Belle that she can go anywhere in his castle except for the West Wing. Naturally, Belle rushes to explore the West Wing the moment she has the chance.

[[folder:Films -- Live-Action]]
* Any film that becomes hard to see immediately gets this appeal attached to it - whether it be a film rating that means people under a certain age can't see it (all 12-year-olds dream of sneaking into an R-rated movie), distribution or ownership rights issues preventing its release/rerelease, or content issues compelling the studios to voluntarily withhold it. A prime example of the latter would be Disney's 1947 ''SongOfTheSouth'', unavailable in the US for decades because of concerns about [[ValuesDissonance now-outdated racial stereotypes]] - this has, of course, led to many annoyed fans who want to see it.
* ''Film/TheAvengers1998''. While going to have tea with Mother, Steed warns Mrs. Peel not to take a macaroon because they're Mother's favorite. Guess what she does during the meal to tease him because he's so straitlaced. At the end when she and Steed have tea with Mother again, she deliberately doesn't take a macaroon as a gesture of friendship to Steed.
* In one segment of the ''Series/TalesFromTheDarkside'' movie involves a man who witnesses a demonic monster brutally murder someone. The monster spares his life on the condition that he never tell anyone else about it. Years later, the man is married to a beautiful woman and has two children... guess what he does? [[spoiler: The minute he tells his wife about the monster and the killing, she ''turns into the monster'' and kills him, then leaves with her now-equally demonic-looking children.]]
** This is very similar to the "Yuki-Onna" (snow witch) segment of the Japanese anthology ghost film ''Film/{{Kwaidan}}''. Only difference is, the Yuki-Onna spares her husband's life on account of their kids.
* PansLabyrinth's Pale Man would like to draw your attention to the wonderful food before it [[spoiler: and away from [[EyesDoNotBelongThere its hands]]. [[MoreTeethThanTheOsmondFamily And its mouth]]. [[EyelessFace And its]] [[NightmareFace ''face'']].]] [[color:white: And the fact that it's behind you right about now!]]
* Represented by the Holy Grail in IndianaJonesAndTheLastCrusade. The grail could not leave its resting place and acted as a forbidden fruit that no one was supposed to obtain. Dr. Elsa Schneider discovered this [[spoiler: the hard way when she tried to take the grail out of the temple and triggered a CataclysmClimax. She found herself suspended above a deep chasm with a choice to let Indiana pull her to safety or reach for the grail. Obsessed, she thought she could reach it, but fell to her death when her hand suddenly slipped out of its leather glove. Indy himself almost repeats the tragedy until his dad [[YouCalledMeXItMustBeSerious calls him Indiana rather than Junior]], which is enough of a surprise to make Indy listen and climb out]].


* The [[TropeNamer Trope Namer]] can be found in the [[Literature/TheBible Book of Genesis]] Chapter 3.
* Lampshaded in ''Literature/ABrothersPrice''. Cullen, who is introduced by sneaking into Jerin's room, tells him that "even the air smells better" now that he is in a place where ''he'' decided to go. (While not technically forbidden from talking to Jerin, he ''was'' supposed to stay in his own room at that point in time.)
* [[LampshadeHanging Lampshaded]] by PiersAnthony in the ''Literature/{{Xanth}}'' series. All knowledge not suitable for children (foul language and especially sex) is supposed to be protected by a ''literal'' Adult Conspiracy (''The Color of Her Panties'' employs the Conspiracy as a major plot element). With a name like that, children in Xanth are practically compelled to try to break the Conspiracy (though breaches don't appear to occur very often).
* In ''LittleWomen'', right after Meg has decided to reject John Brook's proposal out of fear, Aunt March arrives, jumps the gun, and [[ParentalMarriageVeto orders her not to accept him]]. Meg's response: "[[NiceJobBreakingItHero I shall marry whom I please]], Aunt March, [[ScrewTheMoneyIHaveRules and you can leave your money to anyone you like!"]]
* In JohnCWright's ''The Golden Age'', Phaethon is warned that he can recover from his LaserGuidedAmnesia only at the price of exile.
* There are a couple in ''Literature/TheChroniclesOfNarnia'' by Creator/CSLewis which isn't too strange since a lot of the stories are religious in nature, with lots of [[Literature/TheBible bible]] references and parallels.
** In ''Literature/TheMagiciansNephew'', the primary reason Digory rings the [[SchmuckBait bell]] in Charn is [[CuriosityIsACrapshoot to find out what will happen]], but the warning of unspecified danger in the bell's inscription doesn't help, either:
-->Make your choice, adventurous Stranger;
-->Strike the bell and bide the danger,
-->Or wonder, till it drives you mad,
-->What would have followed if you had.
** In the same book, this trope is why Queen Jadis climbs the garden wall and ''steals'' apples of immortality which are offered freely to anyone who comes in by the gate and takes them for the sake of others. Digory, who learned his lesson after the incident with the bell, is not tempted by this warning; Jadis gives him pause only when she tells him the fruit could cure his mother's illness.
** In ''Literature/TheVoyageOfTheDawnTreader'', Lucy, reading through a [[TomeOfEldritchLore spellbook]], comes on some forbidden spells. Aslan's intervention helps her resist the temptation to cast a spell that would make her the most beautiful woman in the world but cause misfortune to others, but as a direct result she immediately makes up her mind to cast another spell which will tell her what her friends think of her (and regrets it, since it shows her one of her friends bad-mouthing her to another girl).
* A favorite device of Creator/EdgarAllanPoe in many of his short horror stories involves a character/narrator who is overcome by the urge to kill someone for no other reason than because he knows it is wrong and he shouldn't. He is aware of this psychology, he has no reason to give in to these urges, but it drives him crazy until he does. Poe's own term for this phenomenon is [[http://en.wikipedia.org/wiki/The_Imp_of_the_Perverse "the Imp of the Perverse."]]
* ''Literature/HarryPotterAndTheOrderOfThePhoenix'': Hermione delightedly explains that Professor Umbridge has done the one thing that will guarantee every student will read Harry's interview with Rita Skeeter: [[NoSuchThingAsBadPublicity ban it]].
** Ironically, in the first book, there is a corridor that is designated as forbidden, which the characters only end up in by accident. Apparently, everyone else took Dumbledore's warning of a "most painful death" seriously. The same goes for the actually named ''Forbidden Forest'', which the characters only wind up in because circumstances force them, and which most people avoid due to rumours of it being filled with horrible beasts (though the Weasley twins had apparently made attempts to enter it). However, the forest is entered again in nearly every book; Hagrid once held classes in there (though Hagrid is of the opinion that nothing in the forest would harm anyone with him because its denizens know him so well, and he seems to be right for the most part).
* Mentioned in Creator/TerryPratchett's ''[[Literature/{{Discworld}} Thief of Time]]''. Susan wonders why someone would build a clock that stopped time and then realizes: "If you put a large switch in some cave somewhere, with a sign on it saying 'End-of-the-World Switch. PLEASE DO NOT TOUCH', the paint wouldn't even have time to dry."
** In Creator/TerryPratchett's ''[[Literature/{{Discworld}} Hogfather]]'', Ridcully finds a door marked, "Do not open under any circumstances." So, naturally, he orders it opened, just so he can see why it was sealed shut.
*** By the end of the book it is sealed up again, [[spoiler: but the groundskeeper makes sure not to seal it too well as he knows that the next Archchancellor will want it opened again. He knows how wizards think, apparently.]]
** In ''[[Literature/{{Discworld}} The Last Continent]]'' this is further lampshaded, as they prop open a window to another dimension/time and hang a sign on it saying, "Do not touch the window, not even to see what would happen."
** In [[Literature/{{Discworld}} Lords And Ladies]], the stone circle is specifically ''not'' forbidden territory because of this trope; the people who aren't forbidding it don't want people going there at all.
** ''The Unseen University Challenge'' includes a passing mention of the not-entirely-complimentary nickname "Merkins" for Americans, with a footnote whose text is "do not look this word up in the dictionary" but the subtext is "the dictionary's over there, what are you waiting for?"
** [[MagnificentBastard The Patrician]] has been known to make Vimes take a case by forbidding him to investigate.
* Edward Cullen is like the "forbidden fruit" to Bella when she first meets him in ''Literature/{{Twilight}}''. In fact, the hand holding an apple on the cover is a reference to this trope.
* In many variants of the ChivalricRomance ''The Knight of the Swan'', the knight arrives to aid a lady, marries her or her daughter, but forbids anyone to ask what his name or origin is. When this is broken, he leaves.
* In the revised edition of ''Literature/TheGunslinger'' Walter O’Dim leaves a note stating that if a woman says the word "nineteen" to a man he has brought back from the dead, that he will tell her the secrets of the afterlife, [[BrownNote and it will drive her mad.]] He signs the note with a smily and follows this with [[MagnificentBastard "P.S. Did I mention the word is NINETEEN?"]]
* Pointed out in Creator/AmbroseBierce's ''Literature/TheDevilsDictionary'':
--> "forbidden, p.p. Invested with a new and irresistible charm."
* Played absolutely straight in Book Ten of ''Literature/TheOdyssey'' with Aeolus's bag of winds. Aeolus was a king that Odyssius's party stopped to visit on the first year after winning the Trojan War. He entertains them well, and they stay for a month at his island, then say their goodbyes. To speed their journey, Aeolus gives Odysseus a bag made from the skin of a [[{{Foreshadowing}} nine year old ox]], and inside it is the North, South, and East winds. After ten days of smooth sailing that would probably set some records, they come within sight of Ithica. Odysseus goes to sleep after handling the bag for so long, and his companions, thinking there's gold from Aeolus in the bag, go to peek in it. The other winds burst out, and swept the ships away from their own country, eventually leading to everyone but Odysseus's death, and for him, his homecoming is delayed by nine years. Also a bit of an IdiotBall case, seeing as Aeolus never said any sort of warning not to tell the others what's in the bag (for example, it's not like if someone else knew that the enchantment would be broken), so it's baffling why in the world Odysseus didn't simply tell them as they left Aeolus's island and sate their curiosity early on.
** Probably because he figured then they'd open it to see what winds looked like.
** By sheer coincidence they were swept back to Aeolus' island. Aeolus refused to help them again, taking this incident as a sign that the gods didn't want Odysseus to return home anytime soon.
* Played with in Creator/PatriciaCWrede's ''[[Literature/EnchantedForestChronicles Dealing with Dragons]]''. After accidentally unleashing a djinn from an unlabeled bottle (that one character had been warned not to touch but the other ''hadn't'') Cimorene thinks fast enough to recover the situation, seals the spirit in the bottle again, and then makes an "idiot-proof" label that explains exactly ''why'' it shouldn't be opened to prevent future mishaps. Oh, and the incident also furthers the plot.
* In "A POISON TREE" from ''Literature/SongsOfExperience'', the narrator's foe covets and steals an apple in the knowledge it belongs to the narrator. Of course, it turns out to be poisonous.
* Played unusually literally in Christina Rossetti's ''Literature/GoblinMarket'', where magical fruit serves as a temptation to young women. (Yeah, it's probably a metaphor for something.)
** Seeing as Lizzie gives Laura more of the fruit by letting the goblins press it to her lips and then [[IncestIsRelative letting Lizzie]] [[LesYay kiss the juice off of her]], it's safe to say that the fruit is a metaphor for sex.
* In the first ''Literature/SongOfTheLioness'' book, Duke Roger invokes the hell out of this trope as his second kill-the-Crown-Prince plot when he tells Jon and the other pages how terribly dangerous the Black City is, so much so that even Roger wouldn't try messing with whatever's there. Predictably, Alanna soon catches Jon sneaking off.

[[folder: Live Action Television]]
* The [[ContentWarnings TV content rating system]] introduced in the US in 1996 had the same affect to TV that the "Parental Advisory" stickers listed below had to music. They only let kids know which TV shows were not recommended for them, and therefore, the shows that were totally awesome.
** ''FoxTrot'' lampshaded this in a 1997 strip with Jason flipping through the channels and continuing to change each time he came across something labeled TV-Y, TV-Y7, TV-G, and TV-PG, until he yells, "Is there nothing for a kid to watch when his parents aren't home?" Then he comes across a program rated TV-MA, and says, "Finally."
** Then in 1997, it seems the MoralGuardians had clearly not learned their lesson and expanded on this mistake when they pushed for even more detailed content warnings. In addition to the rating of the show displayed in the upper corner, they had to have letters indicating the content of the show such as L for language, S for Sexual situations, and V for violence. This only helped kids even further with identifying the shows they wanted to watch.
** ''TheOnion'' lampshaded this with a story about the nation's teenage boys lobbying Congress to demand a more precise rating system with explanation such as how, if a teenage boy is to make an informed decision about whether a particular program is worth watching he needs to know exactly what it contains, and a boy complaining about how he sat through an entire program rated TV-MA that had no sex or violence.
** When the UK's Channel 4 launched in 1982, with a mandate for adventurous, push the envelope programming, it made a huge fuss of prefacing its late night risque movies with a red warning triangle. This had the inevitable effect of attracting viewers rather than warning them off as the practice quickly became infamous. It was dropped not too long afterwards. But C4 retained its reputation for being slightly dangerous.
* One episode of ''FatherTed'' featured two [[SchmuckBait big red shiny buttons]] beside each other in an airplane cockpit, labelled "Emergency" and "Dump Fuel". When [[ChekhovsGun first introduced]], and told not to push them, [[CloudCuckooLander Father Dougal]] finds they're irresistibly calling to him. Naturally, later in the show, an emergency occurs and he is told to press the "Emergency" button. Three guesses what goes wrong...
** To top it off, the Captain of the aeroplane does not know what pressing the button marked 'EMERGENCY' actually does as they've never had to press before. Those in the cockpit decide not to panic the passengers by telling them what's going on and just follow procedure and push the button. Unbeknowst on the flight deck the button triggers an alarm in the passenger section and the word 'EMERGENCY' comes up on all the displays and is repeated over-and-over on the PA system.
** Before the start of the series, Dougal evidently once faced the same problem on the bridge of a [=SeaLink=] ferry.
* ''FullHouse'': D.J. Tanner went through the Pandora's Box-scenario with a gym bag belonging to her Uncle Jesse.
* The kids of ''SaluteYourShorts'' get back at a spoiled brat who's made their lives miserable by telling her she's now free to "trash whatever you want to trash, destroy whatever you want to destroy..." ''except'' press "that little red button over there," which promptly sets off a well-organized {{Booby Trap}}ped room that leaves her covered in egg yolks, spaghetti sauce and feathers.
* The Rev. Eric Camden of ''SeventhHeaven'' points out in one episode that ever since his wife put him on a diet, all he wants to do is eat.
** Yeah, but that could also be because he's ''hungry''.
** This is actually why a lot of [[TruthInTelevision diets fail in real life]]. It's not healthy to think of food (of any sort, unhealthy or not) as forbidden, or to think of occasionally eating the wrong food as "cheating" or "slipping up." That kind of thinking leads to people just plain giving up on dieting.
* ''MalcolmInTheMiddle'': Malcolm and Reese find a door with a sign saying it's for authorized personnel only AND "forbidden". Malcolm is hesitant but Reese sways him with "They wouldn't put something like that up unless there was something really bitching on the other side." Malcolm turns to the camera and says "I can't find a flaw in his logic."
** The next scene the two are hauled by a security guard. While Malcolm openly blames Reese, he admits that "It was pretty bitching" making this a bit of a subversion. While they did end up disciplined for their antic, considering the lives of the cast, this case seems to be more an acceptable consequence.
* The programme ''Derren Brown: Trick Or Treat'' had fun with this. One episode involved a member of the public being challenged the go five minutes without pressing the BigRedButton that would kill a kitten. After five minutes of bleeping Series/TwentyFour- style countdown, and repeated reminders to ''not kill the kitten'', she eventually did it at the last second. [[spoiler: The lights went out. When they came back up, the kitten was fine. The woman's psyche...not so much.]]
* Season three of ''Series/{{Heroes}}'' introduces Hiro by him watching a video will of his father Kaito telling him he just inherited a safe, and never to open the safe, or the world may end. The very next thing Hiro does is open it.
** Kaito apparently expected nothing less of his son, seeing that [[spoiler:the safe contains a note telling Hiro to unpause the video, in which Kaito immediately goes '[[TheTapeKnewYouWouldSayThat I told you not to open it!]]']]
* In the ''Series/DoctorWho'' episode "The Impossible Planet", the Doctor, when confronted with a large pit, in the centre of a planet referred to as Hell, which is in orbit around a black hole, with the Devil attacking, discusses with a scientist why they have an urge to jump down the pit, and how the feeling is. [[spoiler: The Doctor resists at first, but later has no choice but to absail down. When he runs out of rope but not pit, he gives into the temptation to fall. However, the Forbidden Fruit in this instance is good- if he hadn't given in, the {{Satan}}-like alien would have been able to escape and take over the universe.]]
** ''Doctor Who'' runs on this trope. Ever since the very first episode, neither the Doctor nor his companions have been able to resist sticking their noses where they ''know'' they don't belong. Have you got that feeling that you shouldn't be poking around somewhere? Poke away! Mysterious deserted city that everyone wants to get away from? Must investigate! Impossibly ringing phone that a mysterious stranger tells you not to answer? "Hello?"
--> "There's something here that doesn't make sense. Let's go and poke it with a stick."
* An episode of ''WillAndGrace'' featured Jack finding a mysterious locked room in Karen apartment that even Roasario is afraid to enter. Jack relented after Karen literally wrestled him away, only to fall into the room on accident. [[spoiler: The room is a nursery that Karen set up after a pregnancy scare; the fact that she kept it at all is a major PetTheDog moment.]]
* ''CaitlinsWay'': When Caitlin and Griffin are looking for a shortcut home, Caitlin instantly wants to cut through a field with a NO TRESPASSING sign simply because she saw the sign there, calling it "an invitation."
* Symbolically invoked in ''Series/{{Battlestar Galactica|Reimagined}}''. When when [[spoiler: Ellen]] is trying to convince [[spoiler: Boomer]] that the ''Final Five'' had the right idea, [[spoiler: she]] is eating from a bowl of apples. At some point, [[spoiler: she]] offers one of them to [[spoiler: Boomer]] but [[spoiler: Boomer]] refuses, symbolising that [[spoiler: she]] prefers to remain on [[spoiler: Cavil]]'s side.
* In one ''MarriedWithChildren'' episode, Al was accidentally circumcised and had to abstain from sex for a month. For most of their marriage, Al put great effort into avoiding sex with his wife. But now that it was forbidden, she suddenly became some sort of irresistible sex goddess whose every casual action seemed to turn him on.
* ''LizzieMcGuire'' The episode "First Kiss" has Lizzie getting her first boyfriend, which her dad isn't too thrilled about, but her mom assures him that the number one way to make a boy even more appealing to a girl is to tell her she can't see him.
* ''{{Underbelly}}'' faced this problem on it's release, as the court cases for Victor Brincatt and Thomas Hentshel (the people behind the murder of Jason Moran at his kid's Auskick clinic) and other cases in the Melbourne Gangland War were proceeding at the time. Out of fear that the jury would be influence by the show it was banned in Victoria, with one notable exception being episode five. Freak weather conditions in Tasmania bounced the signal to Victoria, allowing people in the state to get their first glimpse of the show.

* The "Parental Advisory" label put on some albums in America (and on American albums sold overseas), also known as the "Tipper Sticker" after the {{Moral Guardian|s}} who pushed for it. A number of people have observed that putting a Parental Advisory sticker on an album only makes young people want to listen to it more. Indeed, the design of the sticker has attained cult status, and can be found on T-shirts, signs, and similar paraphernalia.
** One such person was Creator/GeorgeCarlin, who entitled one of his albums ''Parental Advisory: Explicit Content''.
* "Forbidden Fruit" by Music/TheBand.
* "Beans in My Ears", by Len Chandler, covered by The Serendipity Singers, involves a bunch of kids being told not to put beans in their ears, so immediately doing so. According to TheOtherWiki, doctors complained that the song inspired kids to put beans in their ears.

[[folder: Religion and Mythology]]
* The TropeNamer - the original Forbidden Fruit in the [[Literature/TheBible Garden of Eden]].
--->'''Genesis 2:16-17''' : And the L[-ORD-] God commanded the man, “You are free to eat from any tree in the garden; but you must not eat from the tree of the knowledge of good and evil, for when you eat from it you will certainly die.”
** There was a short story about the subversion of this example, in which Adam and Eve eat the fruit, are confronted by God, and openly admit to doing so: it's ''their'' garden now, and God ''gave'' them the wit to make choices for themselves, so why shouldn't they exercise it? If he wants unquestioning lackeys, God will just have to destroy them both and make some replacements. Seeing that this pair of humans would rather stand up for their principles than cower or lie, God embraces them both, pleased that he's ''finally'' gotten it right.[[note]] Of course, in the real story,[[spoiler: [[BlameGame Adam puts the blame on Eve for telling him to eat the fruit, Eve puts the blame on the snake for telling her to eat the fruit and God ends up punishing them all.]]]][[/note]]
** [[SadlyMythtaken The exact species of fruit wasn't mentioned.]] Much like FourIsDeath, [[StealthPun it's portrayed as an apple because the Latin word for apple, malus, also means "evil".]]
* Pandora and the box she was told never to open. The Greek Gods, who were huge bastards at the best of times, gave her the box, told her not to open it, then gave her a huge amount of curiosity, so that eventually she WOULD open the box. And this was to punish mankind for accepting Prometheus' gift of fire. She opened it, and the world has been suffering for it ever since, though surprisingly, there wasn't a large line of angry Greeks ready to kill her. Since they were the ''first'' evils, maybe the typical reaction was: "Hmm. I wonder what this i--OHMYGODAAAAAHHH!"
** Some variations include that Hope was the one good thing to come out of the box, although in some versions she had to open the box a second time for it to come out. In another, "Foreboding" (the foretelling of one's ills, such that mankind would always dread the future) was the one demon that Pandora was able to keep in the box.
*** Other variations imply that Hope was the ''worst'' evil to come out, as it stops people from giving up when they really should.
*** Yet ''other'' variations go with the logic of Hope being kept inside the box, so that the other Evils wouldn't be able to kill it.
** Depending on which version you read, Pandora herself was created by the gods and given to Epimetheus, brother of Prometheus. Before he was imprisoned by the gods for giving fire to mortals, Prometheus warned his brother never to accept any gifts from the gods. However, Epimetheus became so enchanted with Pandora that he accepted her (and the box she was carrying) without worrying about his brother's warning.
*** Prometheus means "forethought" and Epimethus means "afterthought". Which explains why Epithemus is so dumb.
* In the Tale of Cupid and Psyche, jealous Venus sends Cupid to use his arrows to cause Psyche (whose beauty is praised above Venus, naturally) to fall in love with the most hideous thing in the world. Cupid bungles the assignment and pricks himself with love's arrow, falling in love with Psyche instantly. Psyche finds herself living the good life with a god, but on the condition that she never see her new husband. Naturally, this works out no better than any of the other examples on this page.
** Not to mention how, when Venus ordered her to bring her a portion of Persephone's beauty, Psyche was warned not to eat anything in the underworld except for bread and also not to open the box Persephone gave her. She obeys the first order but disobeys the second, and would have likely slept forever had Cupid not intervened.
** A very similar fate befalls Semele, one of Zeus's lovers.
* Another Greek example is the tale of Orpheus and Eurydice. Orpheus was a famed singer whose fiancee, Eurydice, was bitten on the heel by a poisonous snake and killed, while she was fleeing centaurs who were trying to rape her on her wedding day. Grieving for his lost wife, Orpheus travelled to the underworld and sang to Hades and Persephone, begging them to release Eurydice and allow her to live the rest of her life. They were so moved by his song that they relented, saying that Eurydice's spirit would follow him out of the underworld and she would be restored to life once they reached the surface. The one caveat to this agreement was that Orpheus was never to look back when he was leaving the underworld. Orpheus climbed back out the way he came but, as he reached the surface, suddenly began wondering if Eurydice was really following him... and guess what happened next. Unable to quench his doubt, he turned to check if Eurydice was behind him. She was just a few steps from leaving the Underworld and returning to life but, since he had broken his pledge, her spirit sank back into the underworld and, despite much more begging on Orpheus's behalf, Hades and Persephone wouldn't give him a second chance.
** This exact scenario occurs in ''This Rough Magic'' with the unhappy ending avoided. Everyone was amazed when they reached the surface and the distrustful and suspicious protagonist had managed to not look behind him. Turned out that he hadn't just been capricious when he had that soldier polish his armor so much. He made sure to walk behind that soldier, and could see his wife's reflection behind him in it.
* In JapaneseMythology, Izanami died after giving birth to Kagutsuchi, and Izanagi traveled to the underworld to retrieve her after she ate food that made it impossible for her to return to the world of the living. Upon finding her, she made him promise to not look at her until they escaped. [[ForegoneConclusion Guess what he did]]. He saw that she had become a hideous beast and began to flee from her, which evoked her wrath and caused her to send her minions after him to trap him in the underworld, though he did end up escaping.
* A Lakota story features two hunters seeing a woman. One just wants to sleep with her, but the other [[UncannyValley recognizes that she's a holy woman]]. The first one gets consumed by a cloud and all that is left of him is bones. Then she delivers modern ceremonies to the Lakota people.

[[folder: Tabletop Games ]]
* 4e D&D's H1 module, ''Keep on the Shadowfell'', has a door with a sign that says "Danger! Stay away!" and then scratched below "REALLY!" Guess how many adventuring parties DON'T go through that door?
-->[[spoiler:Inside is a room that holds a very vicious blue slime monster (that has [=TPK=]ed many a party attempting said module.)]]
* Pretty much every Tabletop RPG Dungeon Crawl ever. As in:
-->'''Old Guy in Tavern:''' There's an ancient ruin over yonder said to hold a terrible curse. Legend says that there are creatures in there that will drive you mad! Nobody who has ventured in has ever returned alive!
-->'''Adventuring Party:''' Thanks, old man. Next stop: Evil Ruins!
** Also any game where someone tells you "We used to use that path, but only [[WhoWouldBeStupidEnough a fool or a hero]] would go there now." Off we go, then.
* In ''TabletopGame/{{Paranoia}}'', the Commies initially [[WindmillPolitical didn't exist]] - they'd disappeared long before Alpha Complex was built, but The Computer mistook civil defense files from 1957 as being up to date. Then some citizens got so fed up with The Computer that they decided to become the thing It hated most, even knowing nothing else about it.
** And devote themselves to the ideals of [[CrowningMomentOfFunny Groucho Marx and John Lennon]].
* In ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/{{Warhammer 40000}}'', one of the ways [[TheChessmaster Tzeentch]] gains worshipers is to tempt mortals with the idea of knowledge forbidden by their leaders. It is invariably a BatmanGambit that ends with the person in Tzeentch's debt and forced to act as his pawn.
* In a ''MagicTheGathering'' article, Mark Rosewater used this to explain the goblin mentality, with a button and telling people [[SchmuckBait do not touch that button!]] [[spoiler:It would scramble the page.]]
* ''{{Everway}}'' supplement "Spherewalker Sourcebook", story "The Serpent of Ice". A magician who lives behind a waterfall tells a tribe of hunters that they can take all of the water they want from below the waterfall, but not to take any from the spring that feeds the waterfall. The chief of the tribe and her son decide to take water from the spring anyway, and the water turns into a serpent that kills the son.
* ''{{Risk}}: Legacy'' is a campaign-oriented version of the classic board game, with a series of envelopes that you're supposed to open over a series of fifteen games; they contain various items that affect the layout of the board, the abilities of the various factions, and other things that change how future games are played. There's one sealed envelope at the bottom of the box that simply reads "DO NOT OPEN. EVER". [[spoiler: The contents of this envelope vary between different copies of the game, whose effects include awakening ancient beings, unleashing a supervirus, or knocking the world out of orbit and introducing drastic weather conditions.]]

[[folder: Video Games ]]
* In the video game ''Blasto'', the player would run across large buttons labeled "DO NOT PUSH". Pushing them kills you instantly... most of the time. One rather nasty one [[InterfaceScrew scrambles the buttons on your controller]], making it next to impossible to figure out how to access the menu and get out of the game. And some are ''beneficial''.
* In the original ''VideoGame/SpaceQuest'', the escape craft that Roger had to use early in the game had a button that said "Do Not Push". Pushing it took him to a crazy other dimension called the Daventry Zone [[spoiler:which was actually the world that ''VideoGame/KingsQuest'' took place in]], resulting in a NonstandardGameOver. (Of course, simply seeing it may have been [[RuleOfCool cool enough to try it]], so long as you saved the game first.)
** Curiously enough, Roger claims in one of the sequels [[NoodleIncident that he had actually been to the Daventry Zone and returned]], so canon-wise, it seems something like this actually happened to him.
* Hoborg's crown in ''VideoGame/TheNeverhood'' becomes this.
* ''ThePath''. Like you're really going to stay on it.
* ''VideoGame/DawnOfWar''. [[CantArguewithElves "You stupid humans! You mustn't destroy the Artifact Of Doom! You don't know what you're doing!"]] Worked like a charm, naturally.
* During an amusing conversation in ''VideoGame/DragonAgeOrigins'', Leliana talks about being in the cloister surrounded by chaste young women. She says that being forbidden fruit "[[BiTheWay added to their mystique]]."
** The really amusing part comes from the Warden's "Is ''your'' fruit forbidden?", to which Leliana responds "[[InnocentInnuendo My...fruit?]] I can't believe I'm having this conversation."
** Ser Cullen, a Templar at the Circle Tower, is revealed to have a long-standing crush on the Female Mage Warden. Templars and mages are definitely not allowed to have sexual or romantic relationships for a whole bunch of reasons. The power imbalance is just one. The risk of being torn apart by demons is another. [[spoiler:And Cullen discovers a third when the Tower is overtaken by demon-possessed mages; they prey upon his desire and torment him nearly to madness.]]
* In ''VideoGame/{{Portal 2}}'', the trope is intentionally invoked, several times. Even though you ''know'' that it's going to kill you, you just gotta try.
** One even results in an achievement, for those interested in achievements.
* ''VideoGame/FallenLondon'' has quite a few storylets with the words "this will severely damage your character. Don't do it" or something like it on them. Many of them are [[ViolationOfCommonSense Violations of Common Sense]]. They are always truthful. The wiki (filled out by the players) has precise descriptions of what happens if you do them.
** Most notably in the "Seeking Mr Eaten's Name" quest, which is an entire, very extended storyline ''made'' of this trope. [[spoiler: Among other things, it requires you to commit suicide seven times in a variety of horrific ways.]] This also has the distinction of being Forbidden Fruit ''in-universe''; the [[PowersThatBe Masters of the Bazaar]] will send you a cease and desist note if you take up the quest, telling you in no uncertain terms that it will destroy you.
* In ''VideoGame/MassEffect2'', its revealed that the Male Commander Shepard is this to Tali, despite that she's a Quarian Admiral's daughter, meant to safeguard her people's future, but due to the bio-chemical barriers between Quarians and Humans, she could actually ''die'' from being with Shepard;
--> '''Tali''': I mean a young woman gets rescued by [[KnightInShiningArmour a dashing commander]] who lets her join his crew and then goes off to ''save the galaxy?'' How could she ''not'' develop an interest in him?
* In ''VideoGame/{{Terranigma}}'', the plot begins with Ark breaking down a forbidden blue door and opening a box behind it.

* One panel in webcomic ''Webcomic/CaseyAndAndy'' showed an [[StarWars Imperial Admiral laughing while putting signs around a door saying "Warning! No Bothans!"]]
* Subverted in ''Webcomic/{{Oglaf}}'', in which the main character is pestered by a magic door to open it. [[SealedEvilInACan It isn't explained what's inside it, why it's sentient, or why the Mistress wants him to open it so darn bad.]]
* ''Webcomic/BobAndGeorge'': [[http://www.bobandgeorge.com/archives/040127c Don't touch anything]].
* ''Webcomic/BirdBoy'' [[http://bird-boy.com/volume-1-page-8 gets told he can't hunt and does not listen.]]
* In one ''Webcomic/{{Nukees}}'' strip, Gav decides he absolutely ''has'' to see what's on the other side of a door when he notices there are roughly a dozen different warning signs on it.
* In ''Webcomic/{{Sinfest}}'', [[http://www.sinfest.net/view.php?date=2009-07-28 depicted quite literally.]]
** [[http://www.sinfest.net/view.php?date=2007-06-02 Plus Forbidden Fruit Loops!]]
* In ''Webcomic/BrunoTheBandit'' chess was outlawed after the king lost a game rather badly. This resulted in hundreds of illicit dens offering variations on the game to all-too-eager customers. Once it was finally legal to play again, the main characters pronounced it "dull" and were unable to comprehend their earlier fascination with it.
* Somewhat subverted in one series of ''Webcomic/{{Nodwick}}'' strips. The sorceress She Who Must Be Obeyed had obtained a written copy of That Which Man Is Not Meant to Know, and she is smart enough ''not'' to read it, because she realizes that it's obviously dangerous if no-one should know it. [[spoiler: However, Piffany assures her that only ''men'' are not meant to know it; women can safely read it, because it's something that they know already. When she reads it [[BrownNote not revealing it to the readers]], the fact that such a secret would be so devastating to men almost makes her bust a gut laughing.]]
* In ''Webcomic/GastroPhobia'', Helen ''thinks'' this is the reason Phobia likes Klepto.
--> '''Helen''': Aw, Phobia, I know the taboo of being with a slave ''seems'' exciting at first, but it all comes crashing down if ''my husband'' ever finds out who Sophia's ''real'' father is. You'll see someday this was all for the best.

[[folder: Western Animation ]]
* Dee Dee in ''WesternAnimation/DextersLaboratory'' comes face to face with irresistible Forbidden Fruit (buttons, experiments, etc.) every way she turns in Dexter's lab, and goes for it every time.
* ''WesternAnimation/FostersHomeForImaginaryFriends'', "The Trouble with Scribbles", concerns Bloo and a door marked with, what else? "STAY AWAY. DO NOT ENTER." Mind you, Bloo only becomes attracted to opening it after Mr. Herriman tells him that it contains "deep, dark, mysterious secrets" (emphasis on ''secrets'', as Bloo can't resist knowing them and then letting them out).
* Subverted in ''[[GarfieldAndFriends Garfield's Nine Lives]]'' where a girl and cat live in a idyllic garden, with one condition, that a glass case must never be opened. The characters, who don't seem to have a serious thought in their heads, are tempted to violate that rule. However, while the story plays up their temptation to maximum suspense, at the climax, they leave the case alone and stay in the garden forever.
* Speaking of Garfield, here's one you'll have to see to believe. In one episode of ''WesternAnimation/GarfieldAndFriends'', Jon bet Garfield he couldn't go five minutes without eating. Garfield figured - rightfully - that Jon thought he had no willpower, and took that bet, but poor Garfield was tempted almost ''constantly'' the entire five minutes (shown by a timer provied) everywhere he went by people offering him free food, making him wonder at one point why this never happened any other time. [[spoiler:And the most shocking thing is, this is a subversion. He ''actually won the bet''.]]
* In one episode of ''WesternAnimation/CourageTheCowardlyDog'', when Courage is searching for a storm goddess' pet dog (it's a weird cartoon) he finds that the dog has fallen under the spell of something called the God Bone, a giant bone that is so delicious that a dog who licks it will keep doing so until it starves to death. Despite a stern voice that bluntly warns anyone who enters the room of the danger, it appears that dogs simply cannot resist it. (The numerous dog skeletons surounding it seem to prove this). Courage falls under its spell too, but saves himself and the other dog by somehow managing to pick the giant bone up and carry it with him. [[spoiler:In the end he keeps the bone too.]]
* Subverted in a ''[[TheSimpsons Simpsons]]'' Halloween episode; when Homer sees the school thermostat with the note "Do not touch -- Willie" on it, he reads it as "Do not touch Willie", regards it as good advice, and promptly turns up the heat.
** A more straightforward example is the Halloween episode where Homer [[DealWithTheDevil sells his soul to the Devil]] for a doughnut, then realizes that the Devil can't have his soul if he doesn't eat the whole thing. So he leaves a piece, marks it "Daddy's Soul Donut. Do Not Eat" and puts it in the fridge. Later, Homer goes for a midnight snack, sees his note and goes "Mmm. Forbidden donut... ''chomp!''"
** There's also the time when Bart is at the Wiggum household and he and Ralph get into the chief's closet which contains all his police gear, including weapons. The chief catches them and admonishes Ralph with "What is your fascination with my [[SchmuckBait Forbidden Closet of Mystery]]?"
** Then there's the Simpsons trying to get rid of a faulty trampoline, figuring that nobody will want it. Bart convinces Homer to chain it to a pole, and Snake promptly shows up and steals it.
** In the episode where Homer starts smoking medicinal marijuana, he tells Bart that his medicine, which Bart must '''''[[HypocriticalHumor never use, because it will ruin his life]]''''', lets him see magical, wonderful things that Bart will never, ever experience. '''''Ever.'''''
* Who can forget the History Eraser Button from ''TheRenAndStimpyShow'', probably the most famous example of a BigRedButton you're not supposed to press that gets pressed anyway.
* ''ClerksTheAnimatedSeries'': When breaking into Leonardo Leonardo's skyscraper, Dante and Randall come across a door on the roof with skulls hanging off it and 'MAZE OF DEATH' written in blood on the door. Naturally, Randall wants to go through this door, even though Dante protests and points out the perfectly ordinary door leading to the same place ''right next to it''. We don't see the horrors that they experience when they choose door number one, but given that it apparently includes a minotaur ''and'' [[CoolAndUnusualPunishment a Billy Crystal / Robin Williams movie]], door number two seems to have been the better bet.
* "The Secret Box" episode of ''SpongeBobSquarePants'' centers on [=SpongeBob's=] obsession with a box that Patrick carries around.
* In an episode of ''WesternAnimation/{{Futurama}}'', Professor Farnsworth creates a box with [[spoiler: another universe]] inside and orders Leela to guard it. Of course, this "forces" Bender and Fry to immediately make every effort to steal the box. Leela distracts them with a decoy filled with booze and tangled Christmas tree lights, but then finally succumbs to temptation herself and looks in the real box.
* In the ''WesternAnimation/SouthPark'' episode "Cartmanland", Cartman accidentally succeeds in triggering this trope when he buys a money-losing theme park and plans to use it exclusively for his own use. However, denying everyone else entry creates ravenous public demand, which is copied by other businesses.
* In ''WesternAnimation/TheMisadventuresOfFlapjack'' episode "Mind the store but dont look in the drawer" Dr. Barber tells Flapjack "DO NOT LOOK IN THE DRAWER NO MATTER HOW TEMPTING!!!" in a very deep dark voice. Needless to say, Flap looked in the drawer.
* In the 1930s Fleischer cartoon "Koko's Earth Control", Koko the Clown and his dog walk to the North Pole, where they find a control room with levers that control weather, earthquakes and volcanoes all over the Earth. One lever is clearly marked with a warning not to touch it. Of course, the dog (who can read) can't resist.
* Straight from the first episode of ''WesternAnimation/TeenTitans'', it is made clear that one thing you do ''not'' do if you want to stay on Raven's good side is go in her room. The other members of the team are actually able to resist doing so until the episode "Nevermore", where Beast Boy and Cyborg enter by accident, and then find out why... She had ''dangerous'' stuff in there.
** In fact, the stuff in her room even makes ''her'' nervous sometimes. In "Fear Itself", she wakes up after having a nightmare, looks around nervously, and says, "Maybe I should consider redecorating..."

* The ever-unobtainable AllBlueEntry.
* We all know what happens when you invoke JustForFun/CandleJack, but none of us can ever resi
* Spoiler tags. Especially if it's a series you care about. You know you want to find out [[spoiler:nooooo! They killed your favorite character!!]]
* This is probably the main reason the WondrousLadiesRoom trope exists, and why so many things have fun subverting it or mocking it.

[[folder: Real Life ]]
* There is a psychological reason for this. People are naturally attracted to freedom - that is, having as many options open to them as possible. When an option is closed off your instinct is to open it back up; this is the root (or a contributing factor) to many other phenomena, such as mid-life crises where people start to realize all the options that are passing them by. In general, this effect is greatly lessened if a (good, valid and fair) reason is given for not doing something, since then it feels like you have the option but are choosing not to, whereas if you are forbidden without an explanation it feels like you are being restricted. For the same reason telling people what to do instead of what not to do usually avoids this problem. This effect is strongest in teenagers because they are just starting to realize freedoms but don't have any boundaries set yet.
** This can be seen heavily around late 2012 and early 2013 with New York City's mayor Michael Bloomberg attempting to pass a law that states restaurants and other establishments that sell soda could no longer sell soda larger than sixteen ounces, in order to fight rising health care costs related to obesity. The proposed ban was met with extremely negative responses from citizens and establishment owners alike. People stated that they could easily buy two sixteen ounce cups of soda and it wouldn't solve the problem that the mayor was trying to curb; people who wanted to have a lot of soda would still find ways to get it. In other words, by restricting what sizes of soda people could purchase to drink, people would be ''encouraged'' to drink large amounts of soda by searching for ways around the ban.
* This trope is ''why'' many attempts to discourage tobacco use/cigarette smoking often run into DoNotDoThisCoolThing and/or become the StealthCigaretteCommercial. Too strong of an emphasis on the dangers to life? Congratulations, you've now turned smokers into {{badass}}es who are willing to ''risk their lives'' to look cool! Too much of a "smoking is not a thing normal well-adjusted people do" approach? Oh look, now you have a bunch of people who consider smoking rebellious and a way to lash out at "normal, well-adjusted society," or who intentionally take it up as a form of attention-seeking for how "self-harming" they are. Proclaiming it as instantly addictive to anyone who as much as ''looks'' at a cigarette? Making your campaign laughable to social smokers or to people who try it and go "meh." The more successful attempts to discourage it rely on focusing on immediate/near immediate damage to appearance or performance, or on educating people that tobacco companies ''want'' people to view smoking as ForbiddenFruit rather than "being made into consumers of a product that slowly demands ongoing consumption, ongoing payment for consumption, and threatens their lives and health as it does."
* Similarly, anti-drug campaigns that focus on the idea that ''any'' and ''all'' "illegal" drugs cause instant addiction, violence, or death. The problem with such is that when people ''try'' the ForbiddenFruit and can take it or leave it (that time, at least), have a perfectly nonviolent good time, and/or don't die, ''it entirely discredits the message as BlatantLies.'' Even where such messages are based in fact, e.g. with cocaine/crack, methamphetamine, and opiates, such extreme effects are often the result of somewhat long-term, heavy/frequent and/or extremely irresponsible use, often coupled with intense poverty and/or social sanctions. [[note]] There ''are'' some "recreational" drugs that ''can'' easily kill on first use, but the best example of such (datura/jimsonweed) is entirely legal and barely ever gets ''mentioned'' in anti-drug education.[[/note]]
* When potatoes were introduced in Europe, Antoine Parmentier promoted them by having potato fields near Paris protected by royal troops, thus giving the impression that said vegetables were a delicacy, fit only for nobles' or the king's table. Of course, the men posted were told to accept bribes and retire at nightfall, making it extra-easy for peasants to give in to temptation...
** It was Frederick II of Prussia that did it first, doing the guard stunt in 1744. Parmentier discovered potatoes by being a prisoner of Prussia during the Seven Year War. Parmentier wasn't able to pull off his stunt until 1786.
* The ''Ripley's Believe It Or Not'' museum in Atlantic City, New Jersey has a display piece which is nothing more than a large steamer trunk and a sign which says "Open at your own risk." [[spoiler:The trunk doesn't actually have anything inside that's worth seeing, but lifting the lid activates a hidden mechanism. The person opening the trunk is abruptly hit, via a barely noticeable hole in the floor, with a sharp blast of very cold air. It's an experiment in human curiosity.]]
* The US Department of Energy is currently [[http://www.arch.ksu.edu/seamon/Brill.htm designing a facility in New Mexico to contain hazardous nuclear waste for 10,000 years.]] One of the design challenges is avoiding tempting future treasure-hunters who might mistake the warnings and defenses as proof that something ''valuable'' is stored within.
** [[http://web.archive.org/web/20100731021659/http://www.vanderbilt.edu/AnS/Anthro/Anth101/wipp.html The danger is unleashed only if you substantially disturb this place physically. This place is best shunned and left uninhabited.]]
** One of the big problems is building the warnings and defenses in such a way that they will still be recognisable as such ten thousand years in the future.
* When the Netherlands decriminalized marijuana teenage use dropped from 11% to 8%. Guess we know who was just trying to be a rebel.
* The "Do Not Eat" packet in beef jerky. You just ''know'' it's gotta give you super powers or something...
** Lampshaded in [[http://www.youtube.com/watch?v=mtHmV5Pu6CE&feature=channel_page This Video]] where a character goes on a long discourse about whether or not he can eat it.
* Ditto the "silica gel: do not eat" in clothes boxes. It's a [[http://en.wikipedia.org/wiki/Dessicant dessicant]]: a substance designed to keep everything dry by sucking all the moisture out of the air. Trust me, you don't want it on your tongue.
** The weird part is, it's hard to imagine anyone wanting to eat it... without that label.
** What happens if you eat silica gel? Best answer ever [[http://wondermark.com/394/ here.]]
* The likeliest reason why they have warning labels like "Do not attempt to stop chainsaw with hands or [[GroinAttack genitals]]."
* [[StreisandEffect The]] [[http://en.wikipedia.org/wiki/Streisand_effect Streisand effect]].
* [[http://en.wikipedia.org/wiki/Stalag_fiction Holocaust porn]] was created in, of all places, [[BoomerangBigot Israel]]. Although maybe it was Israel first because of NWordPrivileges?
* The Index of Prohibited Books created by the Roman Catholic Church during the Renaissance. Something on this list will be almost guaranteed to be a bestseller. Most of them are pretty boring though, prohibited for some obscure technicality.
* In the 18th century, physicians for Britain's Royal Navy discovered that sailors could avoid suffering from scurvy on long sea voyages if they ate sauerkraut, which is rich in vitamin C. It was easy enough to order naval officers to eat sauerkraut, but the sailors refused to eat this unfamiliar food with its sharp acidic taste. Admiral Nelson solved this problem by storing the sauerkraut in barrels marked "For Officers' Mess Only", knowing that the sailors would steal and eat food that was exclusively for officers.
* One of Bernie Madoff's tactics while running his colossal [[{{Ponzi}} Ponzi scheme]] was ''turning down'' customers, even when they ''begged him'' to take their money. Not only did this convey the image that Madoff was such an "investment genius" that he could afford to turn down "unworthy" clientele, but it even convinced skeptics that his practices were legit: a scammer wouldn't turn down free money, right?
** This also reinforced the common idea of how his scheme worked. It was believed by many of his investors that he was a fraud but that he was using said fraud to benefit them through his investment firms. Such a scheme only worked if it was small however and most of his investors thought it was a small side business rather than his main source of income.
** Con artists in general, once a strong enough hook is put into a mark, will occasionally encourage the mark to speak to their bankers or lawyers about it. Being told it's a bad idea only reinforces the image that they've found a quick, dirty way to make a fortune.
* Scottish, Welsh and Irish people refer to this as the "Celtic Paradox"; the only way to enjoy something is if you think you're doing something bad.
* Telling someone not to do something will usually result in them doing it. To avoid this, a direct order must be given. Dentists should say "keep your mouth open" instead of "don't close your mouth." The former is an order while the latter is SchmuckBait.
* OscarWilde once said, "If you want to ensure a book is read, have it banned."
** The same premise goes for movies, games, and... well, [[CaptainObvious anything else, really]].
* There is a particularly large fountain on the campus of Florida State University that has a sign saying 'Please Keep Out of Fountain'. It had become tradition for students to throw their friends in the fountain on their birthday, right up until the powers that be decided to do away with the 'keep out of the fountain' rule since no one listened anyway. The birthday dunkings stopped, until a student group petitioned the school to make it against the rules again.
* United States Army Special Forces really liked the green beret, because it looked cool. At least until it became part of their official uniform, only then did they realize how impractical it was.
* This trope is the reason why "straight" guys are such a popular theme for gay porn. They are, by definition, [[IncompatibleOrientation unavailable to gay men]], which makes them that much more desirable.
* Countries where women are legally allowed to go topless at beaches or be nude in public altogether tend to have lower rates of rape.
* Let's just say there's a reason why so many underage viewers tune into AdultSwim or watch R-rated (or higher) movies.
** And why there are so many 8-year-olds on ''VideoGame/CallOfDuty'' and ''{{VideoGame/Halo}}''.
* The public disapproval towards things like swearing and bathroom humour is a major part of the reason why many people find such humour to be side-splitting funny.
* This was the intended effect of the marketing campaign for ''VideoGame/{{Dead Space 2}}'', consisting of middle-aged and elderly people, mostly females, talking about how disgusted they are at how the game is so sick and depraved and how no one should play it. ''ExtraCredits'' blasted this commercial for peretuating stereotypes of gamers being immature idiots, as well as Electronic Arts for continuing to market its games in this way.
* An article on cheezburger.com featured a news story about a heroic teenage boy who saved a female friend from being hit by a car, being seriously injured himself in the process. Mods threatened to ban the first commenter to say "friend zone." Predictably, multitudes began creating accounts specifically for the purpose of saying "friend zone."
* Unlicensed video games had a certain mystique when Nintendo and other companies kept a shorter leash on video game developers. Of course, [[SoBadItsHorrible most of them were terrible]].
