%%One quote per page is sufficient. Put the rest of them on the Quote tab.

A comedy plot line in which a character wrongly believes another character to be gay, either because of misinformation received or because of the supposedly gay character's own misinterpreted words and actions. Once the character is taken to be a homosexual, [[ThreeIsCompany all his words and actions become laden with innuendo]] and further misunderstandings, and [[QueerPeopleAreFunny humor]] ensues.

This can often be caused with supernatural secrets, such as superpowers or lycanthropy, which aren't immediately obvious, or various other embarrassing secrets.

Almost inevitable for HeterosexualLifePartners. This plot may be the first time we've heard them explicitly say they're ''not'' gay (whether we believe them or not is another matter).

A slight subversion occurs when a character is suspected of being gay and [[InsultBackfire takes this as a compliment]], since that person deeply sympathizes with gay people.

For such characters to qualify, they have to be mistakenly assumed to be homosexual, even if the G, H, and L words are not used. However, these characters don't need to retaliate or tell those who have mistaken them that they aren't gay as such characters can easily disprove these mistake through other means such as a revelation of a straight relationship.

See also MistakenForIndex. When the character probably ''is'' gay but is in denial, they're in the TransparentCloset. When the Character is heterosexual but acts like the CampGay stereotype they're CampStraight. Due to the common belief that AllMenArePerverts and AManIsAlwaysEager, any male character who isn't shown to jump at the chance to have sex with a woman ''will'' be mistaken for gay (if not actually gay) by the audience and possibly by the other characters as well (especially male characters). This trope, when used is considered a use of HoYay due to the fact that it is a trope concerning homosexual themes.


[[folder:Anime & Manga]]
* ''Manga/{{Bleach}}'':
** Many characters have been mistaken for gay, including the infamous episode where Renji and Ichigo end up in an awkward position on the floor with Ichigo yelling "Take it off already!".
** This happens to Renji again later in the series during his fight with Szayel Aporro, who is quick to turn him down saying either "I don't lean that way" or "You're not my type" depending on the translation. The humor here is Szayel Aporro, an effeminate pink haired man, being alarmed about being hit on by another man.
** Also happens to [[BaldOfAwesome Ikkaku]], depending on translation. When stationed in the human world, he was living with [[PluckyComicRelief Keigo]] and his [[GenkiGirl sister]] who laid out incredibly cute clothing for him to wear. When Matsumoto spots his clothing, she asks him if he's switched teams. Ikkaku is not amused.
* ''VisualNovel/{{Clannad}}'':
** Tomoya starts telling people that Kyou knocked him over while riding her scooter ("bike") to school, but Kyou, knowing it's against the rules, keeps cutting him off at the first syllable of ([[GratuitousEnglish the English word]]) "bike." When people start asking what he was about to say, his answer is...another English loanword that starts with "bi." Considering Kyou's later glomping of Kotomi, [[AmbiguouslyBi though]]...
** Ryou mistakes Nagisa's asking for help with the theatre club to be a confession of love. She even accepts before realizing it's not.
** Tomoya made Nagisa think Sunohara is gay. She pretends Tomoya is her boyfriend to drive Sunohara away.
* ''Manga/JoJosBizarreAdventure'': At one point in [[Manga/JoJosBizarreAdventureStardustCrusaders Part 3]], Avdol and Joseph become stuck together after Mariah magnetizes their bodies. Avdol tries to slowly slide off of Joseph, which eventually leads to his face ending up on Joseph's crotch, [[NotWhatItLooksLike causing it to look like Avdol is giving him a blowjob]], much to the amusement of some local kids. They temporarily separate, only for the magnetic force [[FromBadToWorse to stick them back together, this time with Avdol's crotch rubbing against Joseph's butt, thus making it look like they're having anal sex]]. An old woman who had mistakenly thought Joseph was crushing on her happens by at the wrong moment, and angrily accuses him of cheating on her with Avdol.
* ''Manga/ThePrinceOfTennis'':
** A big part of the Comedy Tennis developed by Yuuji Hitouji and Koharu Konjiki relays on them being ''very'' touchy-feely with each other and Koharu [[HoYay openly fanboying]] his rivals and teammates [[LovableSexManiac and even groping them at some point]]. All of this is done to disrupt the rivals' concentration and makes the duo's style of play harder to predict... though some wonder if [[CrazyJealousGuy Yuuji actually takes it a bit too seriously]], what with him openly saying Koharu is ''cheating'' on him when he mock-flirts with others.
** In an anime {{filler}}, Inui calls Kaido to tell him that [[ShipperOnDeck he's sure]] [[DatePeepers An and Momo are on a date]] ([[MistakenForLovers they ain't]]), but his cell signal runs out mid-message. [[ComicallyMissingThePoint Kaido]] believes that Inui is asking ''him'' out. HilarityEnsues.
* ''Anime/SailorMoon'':
** In an episode, Makoto becomes very interested in Haruka (an [[{{bifauxnen}} extremely boyish girl]]) and the other characters speculate about her preferences. It turns out that she merely looks up to Haruka as a role model, although fans have debated about what this assertion actually means. This may be one of {{The Artifact}}s from the original [[Manga/SailorMoon manga]], where Haruka isn't an exclusively 'butch'-looking crossdresser; Makoto [[AllThereInTheManual outright explains]] she admires Haruka's confidence in embracing her boyish tendencies, something Makoto hasn't been able to.
** Note Rei is ''technically'' mistaken for gay, if only because most later adaptations drop the more convoluted version of her DoesNotLikeMen status and will make at least one joke about it.
** In one episode Michiru tells Rei that she and Usagi are close, just like her and her girlfriend Haruka.
* In ''Manga/MarmaladeBoy'', when perpetual loner [[DeadpanSnarker Yuu]] suddenly starts hanging out with [[{{Bishonen}} exceedingly popular]] school president Satoshi Miwa, their female classmates and the school newscasters immediately conclude they're getting it on. Hilariously enough, ''Yuu himself'' thinks Satoshi is gay for him when he suddenly starts trying to hang around him for no discernible reason. The real reason is because [[spoiler:Satoshi believed Yuu was his half-brother, as his father was something of a philanderer and he was interested in Yuu's mother, Chiyako. Yuu reached the same conclusion independently, and was shocked when he learned Satoshi's surname.]] Of course, we don't find that out before {{hilarity ensue|s}}d, including [[NaiveEverygirl Miki]] overhearing them having a conversation that sounded like Satoshi pressuring Yuu to have sex with him out of context.
* ''Manga/BloodAlone'': A rare example that doubles as Mistaken For Straight. In one chapter, Misaki gets to meet Kaoru Souma, a famous IdolSinger she admires. It turns out that Kaoru is a lesbian, and she ends up developing a crush on Misaki. However, Misaki misreads the situation and thinks that Kaoru is crushing on her mentor, Kuroe, and begins asking her questions to see if it's true. So poor Kaoru thinks that Misaki is flirting with her, while Misaki thinks Kaoru is trying to get with Kuroe.
* Episode nine of ''Manga/{{Kannagi}}'' revolves entirely around this. After an incident in episode eight involving Daitetsu staying at Jin's house and what happened to part of Nagi's sacred tree, everyone is thinking Daitetsu is gay for Jin and Nagi's furious about it. Zange and Tsugumi attempt to orchestrate a situation that would make Jin out to be a playboy to clear up the rumors, but it's to no avail. People start taking him as the AnythingThatMoves type, which is probably ''worse''.
* ''Manga/OuranHighSchoolHostClub'':
** JerkWithAHeartOfGold Kasanoda develops a crush on {{Bifauxnen}} Haruhi. When he visits her at the club, the YaoiFangirl clientèle is burning with flames of moe. Also, the news of the two raises a few eyebrows among Kasanoda's {{Yakuza}} underlings.
** In the first episode, when Haruhi first enters the music room hoping to find a place to study she encounters the host club who believe she's a guy thanks to her messy hair, unflattering outfit, and glasses. Tamaki also believes she's gay, until he finds out her real gender at the end of the episode.
** In a variation of this, Haruhi's father Ryoji, who is actually bisexual, gave by Haruhi's mother Kotoko the impression that he was gay when they first met because he would often talk about guys he found attractive. She didn't realize that his inviting her to dinner all the time was an attempt to pursue a relationship with her.
** In the last chapter of the manga [[spoiler: Tamaki]] and Haruhi are mistaken for gay when they're having a close moment and dancing together (with her in a dress, even). It isn't until later that the girls figure out Haruhi is really a girl--they originally just thought she was a boy who liked to crossdress as a girl.
* In the first episode of ''[[Anime/CaptainHarlock Gun Frontier]]'', Harlock and Tochiro encounter a sheriff who notes their close camaraderie, gives them an odd look, and the line "It's a free country. Guess that applies to love too." Neither man is amused.
* ''Literature/HalfPrince'' (pay attention, this gets complicated). The female main character is the only [[CrossPlayer female who plays as a male]] in a hugely popular online game. The gay guy in her party, who's her university lecturer IRL, is infatuated with her {{Bishonen}} character, but doesn't know he's a she. Her male childhood friend ''does'', and then angrily [[http://www.mangafox.com/manga/1_2_prince/v03/c016/13.html confesses his long-hidden love for her]] to the gay guy, saying that he's known her for 8 years. She overhears this, but because Chinese [[PronounTrouble uses gender-neutral pronouns]], both she and the uni lecturer think he's talking about a ''boy''. Later on as she's racking her brains for the identity of the mystery crush, her twin brother walks in. Both he and the childhood friend are teammates in the game who both play {{bishonen}}. Cue the ''wrong'' penny dropping. The brother, however, knows that the childhood friend is in love with the sister, and wants to support their relationship. When his sister asks, "Do... you... like... him?" he replies [thinking she wanted his approval before she starts a relationship with the friend] [[http://www.mangafox.com/manga/1_2_prince/v03/c017/5.html "Of course! Dad and Mom have even given their approval!"]]. The rest of the inadvertent HoYay just falls into place, and Gui has stated that he would like Prince no matter the gender or age. He's not homosexual, he's [[SingleTargetSexuality Prince-sexual]]. For bonus points, the reason Gui even started teasing/flirting with Prince in the first place is because he saw a male in-game drooling over him and, not knowing that the character was controlled by a female played, decided to have some fun messing with what he assumed was a gay guy.
* In ''Manga/KarakuridoujiUltimo'', this [[CrowningMomentOfFunny happens]] to [[http://www.mangareader.net/770-35507-40/ultimo/chapter-3.html Yamato here]] when Sayama walks in while he's trying to fix Ultimo. [[http://www.mangareader.net/770-35508-27/ultimo/chapter-4.html Sayama doesn't say it outright]], but clearly implies what she means.
** Later, Matsumoto makes an [[http://www.mangareader.net/770-35511-17/ultimo/chapter-7.html understandable assumption]] about Yamato and his best friend Rune, considering that they are together [[HeterosexualLifePartners almost all the time.]]
*** Later it's revealed that Rune is, in fact, the reincarnation of Yamato's LoveInterest from the 14th century. [[IKnewIt Matsumoto was seen blushing during the reveal]].
* In an early chapter of ''Manga/KatekyoHitmanReborn'', poor [[ButtMonkey Tsuna]] gets mistaken at school for "becoming Gokudera's bitch," after Gokudera [[strike: became his StalkerWithACrush]] came to worship and admire him as the Tenth boss. Now whether ''Gokudera'' was mistaken for gay is another debatable story... Well, he has his own girl fanbase at school, but isn't really pleased with them (he finds them just that annoying). But his devotion to the juu-dai-me ''does'' tend to fall into this.
* Happens a few times to Memori and Yuuki in ''Manga/GameXRush'', which makes sense because... Well, just flip through Volume 2 sometime.
* When ''Manga/HayateTheCombatButler'''s title character is questioned about 'why' he rejects Nishizawa's confession, the fact that he possibly likes guys is brought up before he mentions his childhood teaching from [[spoiler: Athena]]. He's just that clueless, girls.
* ''Manga/MyBrideIsAMermaid'':
** Nagasumi is mistaken for gay after he hastily confesses his love for Masa in order to keep Masa's past a secret. ItMakesSenseInContext.
** The Class Rep mistakenly confesses to Sun Seto when she was trying to confess to Nagasumi. She becomes so annoyed that everyone now thinks that she's a lesbian that she decides to roll with it.
* ''Manga/UruseiYatsura''
** In Chapter 15, Ataru is invited to the undersea kingdom of the kappa after he saves a member of their race. The kappa women perform a dance number in his honor, but he's visibly disgusted by their freaky, inhuman appearance. The kappa princess notices this and assumes that he's repulsed ''because he's gay'', so she tries to cheer him up by sending a group of kappa men to entertain him. It goes about as well as you'd expect.
** When Kurama's father is mentoring Ataru, he tells the boy (in reference to combat) to come at him if he ever spots an opening. Ataru misunderstands, and responds by saying "I'm sorry, but you're not my type."
** During Parents' Day, Mendou's mother [[ThrowingDownTheGauntlet tosses a glove]] at Lum's mother in order to challenge her to a duel. Since Lum's mother cannot speak Japanese and has no knowledge of Earth customs, she assumes that Mrs. Mendou is asking for her hand in marriage.
* ''Manga/{{Naruto}}'':
** At the end of the [[Anime/NarutoShippudenTheMovieInheritorsOfTheWillOfFire third Shippuuden movie]] Kakashi is mistaken as being hitting on Naruto, who just freaks out at the implication. The other rookies are quick to begin the teasing.
** When Naruto is going through some TrainingFromHell and Kakashi means to compliment Naruto on how much he is improving, he says, "I think I'm starting to really like you". Naruto takes this the wrong way.
** Kotetsu and Izumo are mistaken for gay by Tsunade in one omake.
** Sai in one filler arc tries to comfort Naruto but looks like he's trying to kiss him - Naruto freaks out and shoves him away.
* Happens about once in every two episodes for ''Anime/AngelBeats'': Hinata will say something (such as "I quite like you" or "I need you!") that makes him sound like he has a crush on Otonashi. Cue Otonashi asking "Are you..." with a troubled look and an AsideGlance, and Hinata hurriedly cutting him off. ''"It's not like that!"''. It's pretty much a RunningGag by now. The hand gesture that Otonashi does when he asks this actually means/indicates "gay" -- sort of the Japanese equivalent of doing the limp-wrist thing.
* Often the case with Tooru and Yuujirou from ''Manga/PrincessPrincess'' with Tooru saying "there's nothing between me and Yuujirou!" and Yuujirou... [[HoYay not exactly denying it]]. Granted, he had the idea to help drive Tooru's {{Yandere}} stepsister away, but...
* ''Anime/{{Pokemon}}'': Happens to James in the episode where he decides to dress up as "The Flaming Moltres". It happens in the form of a joke from Jessie when she and Meowth get embarrassed after James starts acting flamboyantly in his Moltres outfit. When Meowth asks where James got the outfit, Jessie responds "I think that costume came right out of his closet" which is basically a coming out of the closet joke.
* ''Lightnovel/FullMetalPanic'': In the novel's side story, Tsubaki accidentally confesses to Sousuke instead of Kaname (due to his glasses being off), while he was trying to reveal to Mizuki that he won't reciprocate her feelings because of this person he loves. Sousuke is shown to become very disgusted and nervous after receiving this confession, and afterwards, the entire school thinks he has a gay crush on Sousuke.
* ''Manga/KaguyaHime'': [[HeterosexualLifePartners Yui and Midori]] are not, in fact, doing it. Despite what everyone thinks.
* ''Kodomo no Jikan'':
** At the end of chapter 53, Rin, Kuro and Houin-sensei interpret Oyajima and Aoki's argument as a lover's quarrel.
** Prior to that, teasing from Houin and Aoki cause Shirai to think this way about Oyajima.
* ''LightNovel/KyoKaraMaoh'':
** Yuuri is mistaken for gay by his whole kingdom.
** There is also the episode where Yuri and Gwendal are mistaken as an eloping couple (they were chained together)
* ''[[Manga/RosarioToVampire Rosario+Vampire]]'': Other characters mistake Fang-Fang Huang's obsessive attempts to get Tsukune to join his mafia family as him being gay for Tsukune. It doesn't help that he's [[AmbiguousGender rather androgynous]] and his initial recruitment speech includes such lines as "job for life by my side", "become part of my family", and "[[HoYay passionate bonds between men]]".
-->'''Tsukune:''' I think I'm in the wrong manga...
* ''Anime/PleaseTwins'': Because Maiku hasn't been ogling them, Karen and Miina worry he is gay. So they crank up the FanService level to try and get a reaction out of him.
* ''Manga/CardcaptorSakura'': Syaoran thought he had a crush on Yukito, but it later turned out he was just attracted to the high amount of moon energy inside him.
** You could interpret him as bi, though. And just to nitpick: the reason why he can't be gay is that he falls in love with Sakura, not that he wasn't really in love with Yukito (since he could have turned out to be gay anyway).
* ''Manga/{{Amatsuki}}'': In the manga Heihachi comes to the conclusion that Toki is hitting on him, and sadly recommends that Toki should be with Kon instead, as Kon is more good-looking.
* ''Manga/ViolinistOfHameln'': The other characters flat out accuse Hamel and Raiel of being gay a few times.
* In a chapter of ''Manga/{{BECK}}'', Sayaka's friends egg her to make a pass on Koyuki without even knowing about his relationship with Maho. When Sayaka finally musters her courage to at least hold his hand, he starts remembering Maho and runs off, apologizing. Then, her (Sayaka's) friends start thinking he's gay (and, to make things worse - in a sense - Sayaka [[PutOnABus never appears again in the manga from that point on]]).
* ''Manga/SchoolRumble'':
** Tani-sensei keeps getting into gay situations with Harima.
** One episode has Harima try to turn in a resignation letter to the teacher and a love letter to Tenma, asking her out on a date. The letters, of course, get switched and [[CrowningMomentOfFunny Harima and the teacher go to the movies together at the end of the episode.]]
* ''Manga/KOn'':
** Tsumugi is mistaken as a lesbian in an episode, and when confronted directly, she explains that she only innocently enjoys the sight of "girls bonding." But was it really a [[YuriFan mistake?]]
** In TheMovie, Azusa mistakes Yui for gay after coming across [[LessDisturbingInContext some suspicious looking notes with words like "Azu-nyan LOVE"]] scrawled about the page.
* ''Manga/AhMyGoddess'':
** In one early chapter of the manga, LoveGoddess Peorth mistakenly believes Keiichi (who she's trying to woo, a little too well) and Tamiya are lovers, due to her steady diet of Shoujo manga. She responds by trying to woo Tamiya, and [[HilarityEnsues things get interesting]] when Tamiya ''actually becomes infatuated with Peorth''.
** In the anime, HarmlessVillain Mara gets not just mistaken for gay, but Mistaken For Gay ''Rapist'', not once but twice (by Sayoko and Megumi).
* In chapter 23 of ''Manga/OmamoriHimari'', [[CatGirl Himari]] switches back to human form right on top of [[UnluckyChildhoodFriend Rinko]]. Rinko's mother walks in a moment later to find a nude Himari straddling Rinko on top of her bed. {{Beat}}.
-->'''Mother:''' ''J-J-Just now, I witnessed my cute little girl's hidden passion!! This is the final drop for a mother!!!''\\
'''Rinko:''' M-Mom!! Don't break down on me now!!\\
'''Himari:''' I'll only ask this once: has anything unusual happened?\\
'''Rinko:''' Yeah, because of you my relationship with my family has just become unusual...
* ''Manga/{{Working}}'' has two cases: the highly [[DoesNotLikeMen androphobic]] Inami (how she turned out straight we'll never know) and [[OlderThanTheyLook Popura]] due to her obsession with Kotori-chan (reaching the levels Takanashi has with everything cute), which she insists is just admiration because the latter's everything she wants to be ([[TakeOurWordForIt though really all we have to go on is her assertion]]).
* ''Anime/PuellaMagiMadokaMagica'': Hitomi assumes that the reason Madoka and Sayaka don't hang out with her after school any more is because they've undergone a RelationshipUpgrade, when in reality they've been tagging along with a MagicalGirl. Though it doesn't help their case that Sayaka was acting quite flirtatious. She also might have (even subconsciously) ''wanted'' to believe that the two were a gay couple, since she was [[spoiler:chasing the same boy Sayaka did.]] It also doesn't help that Madoka has a [[CastFullOfGay Cast Full of]] AmbiguouslyGay / [[AmbiguouslyBi Bi]] schoolgirls, of which Hitomi is the only ostensibly straight member. And Sayaka ''was'' coming on pretty strong. Lampshaded by Dub!Sayaka: "[while Hitomi freaks out] I can't believe she's going there..."
* (fandom aside) ''Manga/{{Saiyuki}}'' has a few. Genjo Sanzo gets it quite a lot from random strangers to the extent he's nicknamed Mr. Gay by someone in a bar in the first OVA, and was even hit on once by a drunk DepravedBisexual in another bar. He's not particularly happy about this fact, considering that he was bullied as a child partly because it was rumored he was his adopted father/mentor's catamite. The other characters naturally find it hilarious, though. Ironically, in ''Gaiden'', his previous incarnation was rumored to be in the same situation with Goku's younger self. Tenpou and Kenren in ''Gaiden'' also have rumours flying about all over the place which is TruthInTelevision for two people who are close friends. Mentioning it is likely to get you beaten into the ground though. Also played completely straight when Gojyo and Goku are fighting on a bed and a girl walks into the hotel room, [[SorryToInterrupt jumps to the wrong conclusion and quickly hurries out]].
* In ''Manga/GirlGotGame'', Chiharu being SweetOnPollyOliver leads to Hayama making this assumption . . . and being a very ardent [[ShipperOnDeck shipper]], going so far as to offer Chiharu a gay sex guide and wishing him happiness. (Chiharu does not appreciate it.)
* In ''Manga/TheWorldGodOnlyKnows'', [[spoiler: post-capture Yui]] publicly confesses to Keima, while [[WholesomeCrossdresser wearing a boy's uniform]]. It also didn't help that she was acting like the Seme while Keima uncharacteristically acted like the Uke. Later on, she intended to fix this trope by [[spoiler: trying to get Keima to wear a dress. And succeeded.]]
* Jelice from [[Manga/HatenkouYuugi Dazzle]] is an extremely {{camp|Straight}}y priest. Everyone just assumes he's gay. [[HeroicAlbino Alzeid]] was understandably shocked [[http://www.mangafox.com/manga/hatenkou_yuugi/v03/c023/7.html when Jelice told him about the girl he loved.]]
* ''Manga/AiOreLoveMe'':
** Akira looks like [[DudeLooksLikeALady a girl]] at first glance however [[UsefulNotes/JapanesePronouns he uses "ore"]], so people think he and [[{{Bifauxnen}} his girlfriend Mizuki]] are gay lovers.
** This happened to Ran when he was advancing on Mizuki. All of a sudden some YaoiFangirls started squealing and having a fit.
* ''Manga/RanmaOneHalf'':
** Ranma and Akane assume that [[WholesomeCrossdresser Tsubasa Kurenai]] is a lesbian.
** Ranma and Akane have had a lot of romantic moments when he's [[GenderBender in his girl form.]] At times, this makes Akane worry that people will think they're lesbians. Mariko thought they were lesbians. Still does.
** In the manga, Ranma unknowingly eats some pork buns that make him hug anyone who sneezes. Kuno challenges him to a fight and Ranma accepts, expecting it to be a simple battle. Unfortunately for Ranma, Kuno keeps sneezing the entire time. His constant [[TheGlomp glomping]] makes the entire school think he's got the hots for Kuno. [[HilarityEnsues And so, hilarity ensues.]]
** And then there's the "Fishing Rod of Love", which will make anyone who get snagged with it fall head-over-heels for whoever fished them. Ryoga ends up buying it to get a shot with Akane. He casts the line blindly and... ends up fishing Ranma instead. The worst part of it is that it's ''Akane'' who ends up making the assumption about Ryoga, even after the whole mess is undone. As for Ranma, well, he got off relatively clean.
* When Nakamura from ''Manga/{{Nichijou}}'' is finally alone with [[RobotGirl Nano]], she says she wants to know what Nano is actually like. She was referring to how she was constructed, but Nano took her own interpretation.
* In ''LightNovel/MayoChiki'', practically all of the school suspects this of the main character, Jiro, after he's seen hanging out with [[TheOjou Kanade's]] butler, [[UnsettlingGenderReveal Subaru]] a little too much.
* In the first episode of ''Manga/{{Cyborg 009}}'' ''VS'' ''Manga/{{Devilman}}'', Akira tells Miki that he's sleeping over at Ryo's house. In response, Miki grins and says "How suspicious...," which actually makes Akira blush in embarrassment.
* Oswald, the older brother of Lacie in chapter 67 of ''Manga/PandoraHearts''. "I didn't know you swung that way." "I'm not sure what you mean."
* ''Manga/DNAngel'': Daisuke and Satoshi have a lot of HoYay together and Satoshi is suspected by fans whether correctly or not that he is gay for Daisuke. In episode 17 Daisuke and Satoshi are at the beach on a school trip and Satoshi helps dig Daisuke out of the sand. Some girls watching end up mistaking them for being gay for each other.
* Eitaro from ''Manga/LoveJunkies'' is mistaken for being in a relationship with [[TheCasanova Obi]] by his coworkers.
* In ''Manga/{{Nicoichi}}'', the relationship between Makoto and Natsumi is often mistaken as such, because Makoto is simply [[WholesomeCrossdresser too good in cross-dressing]] and thus will appear as a lesbian couple to those who does not know his [[LivingADoubleLife secret]].
* In one of the ''Anime/RevolutionaryGirlUtena'' fillers, Touga mistakenly believes Nanami to be a lesbian.
* In ''Pump Up!'' the protagonist mistakes her crush for being gay, due to his intense admiration for a fellow classmate. It turns out [[spoiler:he likes her]].
* ''Manga/DailyLivesOfHighSchoolBoys'':
** ''High School Boys and Horoscopes'': Motoharu saw Hidenori "kissing" Yoshitake. The former was only trying to squish a hornet perched on the his nose. When they run into Karasawa, he [[CrazyPrepared whips out a can of pesticide and sprays it onto their faces]].
** ''High School Boys and Drop-Kicks'': The sudden physical closeness between Hidenori (on a visit to his maternal grandparents' hometown) and Kiyohiko was seen by Emi as "[[BoyMeetsGirl Boy Meets Boy]]".
* [[LovableSexManiac Manabe]] of ''Manga/KotouraSan'' often have GirlsLove fantasies when his girlfriend Haruka is a bit too close with another girl in the cast; once between Haruka and Yuriko is episode 2 and once between Haruka and Hiyori in episode 5.
* In ''Manga/OnePiece'', Nami and Franky [[FreakyFridayFlip switch bodies]], and Nami, in Franky's body, gets taken away by Rock and Scotch. Nami, forgetting she is in Franky's body, starts screaming about how sexy "she" is and that guys may want to take "her" for "herself." Rock asks Scotch if he has any idea what their hostage is talking about, to which Scotch assumes Franky must be gay.
* ''Manga/ServantXService''
** In Episode 3, Chihaya outright declared Yutaka as her rival. Yutaka at first wondered if "she's the type who likes other women." He was soon disabused of the belief, though, when she started talking {{cosplay|otakugirl}}.
** The ChildhoodFriends-turned-UnknownRival relationship between Yutaka and Jyoji was often mistaken to be gay--CosplayOtakuGirl Chihaya once used [[BoysLove BL]] to describe their relationship, and it is implied Yutaka's cananova tendencies was in fact a way to clarify his sexual orientations, and both of them do have girlfriends in the end of the anime adaptation.
* An interesting version in ''LightNovel/ACertainMagicalIndex''. Due to the Angel Fall spell, Touma's father Toya [[LieToTheBeholder sees]] Kaori Kanzaki as Stiyl Magnus. Kaori is irritated by this but plays along, but when Touma and Toya accidentally walk in on her bathing, she angrily attacks them with her [[CantBatheWithoutAWeapon sword]] and they barely manage to escape. Toya is confused about why "he" would be so embarrassed about being seen naked by another man and concludes that "he" is gay, adding NotThatTheresAnythingWrongWithThat. Toya never learns the truth, which means things would get interesting if he ever met the real Stiyl in the future.
* In ''Anime/SamuraiFlamenco'', Mari tries to seduce Goto, but he will have none of it, saying he already has someone (meaning his girlfriend in a LongDistanceRelationship). She ''immediately'' assumes he is referring to [[HeterosexualLifePartners Masayoshi]]. At the end of the same episode, she finds Goto headlocking Masayoshi. [[HoYay You can't really blame her.]]
* In Webcomic/AxisPowersHetalia (Episode 32), Ancient Rome assumes that Germany "plays for the other team" when he says that he doesn't have women all over him like [[SexGod Rome]] used to. Germany responds with a very violent: [[CrowningMomentOfFunny "I WILL PUNCH YOU IN THE THROAT!"]]

* ''Manga/PrincessJellyfish'' has this for Tsukimi and WholesomeCrossdresser Kuranosuke. A couple of school kids actually call them lesbians when they see them together, unaware of Kuranosuke's cross-dressing tendencies. It doesn't really help that Kuranosuke was developing feelings for Tsukimi.

Kagami says the phrase "I want to [[CensoredForComedy ***]] with Konata!" as she's waking up, in front of her sister Tsukasa. Tsukasa gets the wrong idea and, despite her sister trying to explain, just says she won't tell anyone as she awkwardly leaves the room.
* Marika from ''Manga/BokuraNoHentai'' frequently got called homophobic slurs in elementary due to her feminine nature. She does like boys but she's {{transgender}}, not gay.
* A RunningGag in ''Manga/HatsukoiZombie'', after the protagonist Tarou confesses his love to Ibusuki, the "girl" he liked as a child, hoping that it will make CuteGhostGirl Eve (who is supposed to represent Ibusuki) disappear. It doesn't work, as Tarou doesn't have any real feelings for the male Ibusuki, but as a result the whole school ends up thinking he's gay. Funny thing is, after a while he doesn't even try to deny it and just goes with it.

In the second chapter, Natsuko's friends catch them at it and come to the obvious conclusion. Haruko rolls with it, going so far as to kiss Natsuko and declare she's the dominant one.

[[folder:Comic Books]]
* Creator/GregRucka mentioned a story that he'd like to do but knows DC would never let him: A group of Gotham socialites are discussing their relationships with [[Franchise/{{Batman}} Bruce Wayne]], and one of them eventually confesses that she's never had sex with him. They compare notes, realise that ''none'' of them have actually had sex with Bruce Wayne, and come to the inevitable conclusion...

** Nightingale and Sunbird also face rumors of lesbianism after an unlicensed comic portrayed them as "closer than sisters" and strongly implied there was something going on there
* The relationship between Nico and Karolina in ''Comicbook/{{Runaways}}'' was complicated by Karolina's [[IncompatibleOrientation crush on Nico]]. When Nico swore off men [[spoiler: after learning that her boyfriend Alex Wilder was TheMole who had betrayed them]] Karolina believed that Nico had decided to "switch" and subsequently attempted to kiss her and was gently rebuffed. The resulting conversation is extraordinarily awkward as Karolina wonders if the problem is that she is going "too fast," whereas Nico [[ObliviousToLove had never realized that Karolina was in love with her in the first place]]. The ShipTease between the two characters would be a regular occurrence through the remainder of the series' run, and it was eventually revealed that Nico and Karolina ''did'' eventually kiss, though the kiss was never seen in the comic or described in detail.
* In the Creator/PeterDavid ''ComicBook/{{Supergirl}}'' title, Linda Danvers's parents get the wrong idea when she attempts to tell them about the huge, identity-altering secret she's been keeping.

* ''Comicbook/{{Empowered}}'' had a supervillain team called "Rum, Sodomy, and The Lash". When Emp confronts The Lash, he sadly explains that Rum had to go to an AA meeting, and Sodomy got tired of explaining that he only represents ''heterosexual'' sodomy and quit.

* ''ComicBook/MortadeloYFilemon'': There is a moment in a story when the General Director walks in on them in the worst possible moment and thinks Filemon is proposing to Mortadelo.
* Happens to ComicBook/DoctorStrange in the miniseries ''The Oath'' often enough to qualify as a running gag. First, random street toughs assume he and his friend and servant Wong are a gay couple, then Night Nurse seems to assume that Wong calling Stephen 'master' is sexual in nature (alluded to by her remark about his being unable to pass comment on 'other people's fetishes'). ''[[RuleOfThree Then]]'' Reginald Pavlish, a would-be patient of Strange's in his last days as an [[DrJerk arrogant young surgeon]] offers 'something else' to repay Strange, in what reads very nearly as an inverted ScarpiaUltimatum (Strange turns him down anyway.)
* In ''ComicBook/BlackMagick'' #8, Morgan is in a huff with Rowan because he thinks that Rowan and Alex are an item and that Rowan hasn't told him yet. This causes Rowan to burst out laughing.
* In issue 15 of ''[[ComicBook/JosieAndThePussycats She's Josie]]'', Melody believes her friend Pepper is hitting on her:
-->'''Pepper''': ''Melody, I appeal to you!''
-->'''Melody''': '' ♪ Oh you '''do''', Pepper! But I like '''boys''' better! ♫''
-->'''Pepper''': '' No, no, you ninny! I want your '''help''' ! ''

While not explicitly stated, it's implied that J. Jonah Jameson came to the conclusion that Spider-Man is gay.

[[folder:Fan Works]]
* Frequent in fanfiction. Very. For example, this (in some form) features in [[http://yuletidetreasure.org/archive/64/nothingbeside.html this]] ''Comicbook/{{Watchmen}}'' fanfiction written for Yuletide Treasure. It features a scene of Ozymandias awkwardly jumping to the conclusion that he's being mistaken for gay during an interview -- NotThatTheresAnythingWrongWithThat.
* Somehow, James ''inverts'' this in ''Fanfic/CoOpMode'' by mistaking Taylor mistaking him for gay because of the way she had let him [[HealingHands massage her]].
* In a oneshot called ''[[https://www.fanfiction.net/s/8534217/8/Fate-Stay-Unfinished Archer of King Arthur]]'', the knights of the round table start to believe Archer is GAR for the king based on all the looks he sends him when he's not looking.
* In ''Fanfic/QueenOfAllOni'', after Jade says that Daolon Wong's "in the closet", [[AmbiguouslyGay Ratso assumes it means something else]] (he's actually ''literally'' locked in a closet in the old Dark Hand building).
* In Creator/LittleKuriboh's ''WebVideo/YuGiOhTheAbridgedSeries'', Pegasus is believed to be gay, what with Bakura's Millennium Gaydar pointing at his castle. ([[CampStraight His entire personality]] didn't help.) [[spoiler:However, it is later revealed he was married to [[TheLostLenore Cecelia]], and that [[StraightGay Croquet]] is the gay one]].
* In ''Shocker: Legit'', Shocker comes to the conclusion that Peter Parker is gay -- based largely on a comment Peter accidentally makes about wearing spandex.
* Meta example: ''Fanfic/UndocumentedFeatures'' was written over many long nights where the three authors would go up to their room and plot, and their classmates thought they were gay (or at least bisexual) because who writes fiction on a Friday night?
* Hilariously enough, despite acting like a [[CampStraight stereotypical gay man]] (and the {{Double Entendre}}s don't help), [[spoiler: Zarbon]] is revealed to have a girlfriend in ''WebVideo/DragonBallZAbridged''. Even Freeza was shocked to find out he was straight. Course, in turn, [[spoiler: Zarbon's]] surprised that everyone thought he was gay. Despite acting AmbiguouslyGay even after being outed as straight. Freeza remains convinced that his "girlfriend" is named Chuck, but WordOfGod from TFS confirmed that [[spoiler:Zarbon]] really is straight.
** Even funnier, [[spoiler:Zarbon]] ends up thinking Vegeta is gay because of an ArentYouGoingToRavishMe [[ItMakesSenseInContext reaction]]... and quickly adds NotThatTheresAnythingWrongWithThat.
* A driving force of the conflict during the start of ''Fanfic/{{Assumptions}}''. Everyone assumes this about the athletic, tomcoltish Rainbow Dash. Even her friend Pinkie Pie thinks this, and was hoping to "experiment" with her. One of the reasons she's falling for Caramel, who she'd ignore otherwise, is because he's a nice conversation partner that doesn't judge her.
* ''Fanfic/{{Oblivion}}'' has Alexis Terra and Marley Flowers initially subjected to this...until it becomes clear that [[{{Bifauxnen}} Marley is a woman.]]
* In ''Fanfic/TimeAndAgain'', Naruto fumbles his explanation to Sakura about why he's incapable of seeing Hinata romantically (because [[PeggySue from his perspective, doing so would make him a paedophile]]) so she decides that he must be gay, stating that [[HoYay "it does explain some things"]].
* In ''New Chance'', a ten year old Naruto tells Gaara that he thinks Haku and Sai are gay. While the rest of the Konoha 12, Haku and Sai are eavesdropping. His reasons being that Haku likes dressing like a woman a little too much and he mistakes Sai's attempt to make friends as a case of HaveIMentionedIAmHeterosexualToday.
--> '''Naruto:''' "Haku and Sai have some serious image issues. I think they're gonna come out the closet one day."
--> '''Haku:''' (thinking) "''If we compared the number of fangirls we each had, he'd find out he was wrong.''"
--> '''Sai:''' (thinking) ''[[CompletelyMissingThePoint "Why would I get in a closet?"]]''
* In the ''Manga/{{Bleach}}'' / ''Anime/KillLaKill'' crossover ''Fanfic/ToMyDeathIFight'', Isshin Kurosaki reveals that he thinks Uryu is gay just because he sews, and asks if his father knows he's in the closet. When Uryu indignantly says his father was the one who taught him how to sew, Isshin assumes his father is gay too.
* ''Manga/RanmaOneHalf'' fics:
** In ''[[https://www.fanfiction.net/s/3035486/1/Same-Time-Next-Year Same Time Next Year]]'', according to Nabiki, Akane's frequent statements about how she hates boys have led to a few people wondering if she's a lesbian.
** ''[[https://www.fanfiction.net/s/5393139/1/In-Vino-Veritas In Vino Veritas?]]'' has Ranma, in female form, buying a pregnancy test for Akane. Shampoo runs into him at the store, and assumes that the pregnancy test is for ''him'', due to him being in girl form.
* In ''WebVideo/UltraFastPony'', "A Library With No Twilight", [[LemonyNarrator Phil]] encourages Applejack and Rarity to make out. Both of them yell at Phil--and Applejack is surprised at Rarity's reaction, because she'd always assumed Rarity was gay.
* The ''Manga/PandoraHearts'' fanfic ''Fanfic/BeyondTheWindingRoad'' has Oz and Vincent, before Oz can explain who Vincent really is. His mother mistakes Oz's idea for a family meeting as him being about to come out of the closet and Vincent for his boyfriend, and she's accepting to the point of embarrassing. Oz actually ''does'' come out in a way, but it's more about identity than sexual orientation.
* In ''Fanfic/LokiAgentOfDoomgard'' Verity implies to her mother that Loki doesn't date women to stop her from playing matchmaker. Loki naturally rather uses this opportunity for trolling and doesn't even try to clear the misunderstanding.
* ''Fanfic/TheSecondTry'': When Touji meets Kaworu, he wonders if he's gay. However, when Touji asks him, Kaworu is genuinely clueless about what Toji was implying (but he finds his reaction "very interesting" anyway).
-->'''Toji:''' Hey, you know... the way you're moving and talking... and that smiling... you're not... I mean not that I'd have anything against it... but still...\\
'''Kaworu:''' I am afraid I do not know what you are referring to.\\
'''Toji:''' Yeah, sure, never mind.
* In ''[[https://www.fanfiction.net/s/10960035/2/Savage Savage]]'', Ichigo assumed Tatsuki and Orihime were dating from how close they are. The fact Orihime says stuff like "I promised Tatsuki I would come back to her" really doesn't help matters.
* Due to some misunderstandings in ''[[https://www.fanfiction.net/s/5985329/1/I-Still-Say-it-Looks-like-a-Nail I still Say it Looks like a Nail]]'', [[Series/BuffyTheVampireSlayer Xander]] thinks his uncle [[Franchise/StargateVerse Jack O'Neil]] is gay when he brings up military regulations preventing a relationship with someone named Sam. Later when Xander meets SG1, he thinks "Sam" and "Danny" are short for "Samuel" and "Danielle" rather than Samantha and Daniel, leading to further misunderstandings.
* ''FanFic/YinAndYangSeries'': Fujuju, who's soft spoken and a HouseHusband.
* ''Fanfic/TheLifeAndTimesOfAWinningPony'': In ''Cadance's Lovely Misadventure'', when Cadance was trying to set Shining Armor up with a date and he was trying to say (in a rather roundabout way) he was in love with her, he tried to specify that his ideal date would be in the nobility, and also a close friend. Cadance, knowing that all his other friends were stallions and [[ObliviousToLove not realizing he was talking about her]], concluded he was into guys. Afterwards, Shining was too mortified to correct the misunderstanding, although Cadance caught on on her own later on.
* ''Fanfic/FateLongNight'': When Shirou says he's never had a girlfriend in his life and that he finds Nymeria scary instead of hot, Brandon asks if he's a "sword swallower".

[[folder:Films -- Animation]]
* In ''WesternAnimation/JusticeLeagueTheFlashpointParadox'', Barry Allen decides to tell his mother that he's Franchise/TheFlash, but gets embarrassed when she interrupts and says she already knows he's gay and she's not ashamed. He corrects her, then realizes he has bigger problems when she has no idea who The Flash is (the timeline has changed).
* In ''WesternAnimation/SupermanUnbound'', Steve Lombardi assumes that Clark is gay (oblivious to the fact that Clark and Lois are dating), commenting that he never seems interested in women, and doesn't follow sports, but stays in shape. Lois turns it on Steve and asks if he's interested in Clark.
* In ''WesternAnimation/BatmanAndHarleyQuinn'', Nightwing gets a RagingStiffie while tied up and in the presence of an underwear clad Harley. Amused, Harley says she's surprised because she had always assumed he and Batman were a couple. Shocked, Nightwing says that is definitely not true, and he and Harley have sex.
* ''Disney/ThePrincessAndTheFrog'': During a trolley ride, a guy sitting next to Tiana tries to offer her a flower but, while he's distracted picking the flower, she leaves her seat and he mistakenly offers it to the guy on the other side.

[[folder:Films -- Live-Action]]
* ''Film/LittleFockers'' - The principal of the private school Greg is looking at assumes that Jack and Greg are a couple, a situation not helped by a confused account of the events of the night before when Greg helped Jack with a priapism episode.
* The Bollywood movie ''Kal Ho Na Ho'' has this going on between the two male protagonists, played for laughs. First they get totally wasted and pass out in bed together; totally innocent but when the Indian maid walks in she is horrified. Then later she finds them yelling at each other in what looks like a lover's quarrel. Things like this continue to happen, freaking her out more and more. Finally when the man she is actually a maid to gets married to a woman, she is so happy that she actually hits/shoves the obviously gay interior decorator when he gets too close to the groom.
* Happens in the Bollywood film ''Dostana'' when the two male leads are trying to get a flat. They run with it, because it was the only way to get the place. It backfires though.
* The plot of ''Film/ThreeToTango'' is that Chicago architect Oscar Novak is mistaken for gay and has to keep up the charade because he was hired for the contract of his life on the assumption he was gay so he could act as a safe companion for his new boss's mistress Amy. HilarityEnsues.
* The French movie ''Film/TheCloset'' subverts this; when a photoshopped picture of the main character at a very gay bar in a very gay outfit shows up at his office, he is seen as gay by everyone despite no outward mannerism changes. This is intentional; the photo is sent by his neighbor in an attempt to use discrimination fears to avoid the impending layoff of the main character.
* This appears in ''Film/SnakesOnAPlane'', in which the effeminate, comic-relief air steward states early on that he can't wait to see his girlfriend, resulting in disbelieving remarks from his colleagues. At the end of the film, he is reunited with his girlfriend who turns out to be both real and highly attractive (and also apparently every bit as bubble-headed as he is), while the rest of the characters express their surprise.
* The film ''Film/{{Clue}}'' features Mr. Green, whose blackmail-worthy secret is that he's gay. In the third ending, the final line of the film is him declaring he's going to go home and "sleep with [his] wife." (He was [[spoiler:actually an undercover agent, and pretended to be homosexual to protect his family. Or, this being Hoover's FBI, he was a homosexual who pretended to be a heterosexual pretending to be a homosexual. Interpretations vary.]])
* In the movie ''Film/InAndOut'', Kevin Kline's character is "outed" as a joke by a former student of his, and spends most of the movie denying that he is gay. The trope is ultimately subverted when [[spoiler:it turns out he really is gay.]]
* In ''Film/{{Sextette}}'', Sir Michael Barrington (Creator/TimothyDalton) is confused by the media of being gay, and Barrington constantly reinforces this rumor by naively declaring such lines as "Well, yes, I would say so. [[HaveAGayOldTime Always gay, never depressed. Happy and gay.]] That's my motto", "It's queer to me," he's a "man's man" and that as a coxswain he "coxed the entire crew."
* Near the beginning of ''Film/TheFlintstonesInVivaRockVegas'', The Great Gazoo sees Fred and Barney [[NotWhatItLooksLike lying on top of each other]] and thinks that they're mating (doesn't help that Gazoo's alien race has no females and they reproduce like amoebas). Talk about a [[{{Pun}} gay old time]]!
-->'''Fred''': Oh, no, Barney and me don't, uh... Get off of me! (''shoves Barney off his back and onto the floor'')
* ''Film/AmericanBeauty'': The paranoid ex-Marine neighbor wrongly suspects his son and the protagonist (played by Kevin Spacey) of having a homosexual affair. As it turns out, [[spoiler:he's a closet case himself.]]
* Ashley's best friend Dan in ''Over Her Dead Body'' who it turns out started to pretend to be gay after he is mistaken for it just to stay close to her.
* In ''Film/MyBestFriendIsAVampire'', Jeremy's parents misinterpret what's going on and conclude that their son is gay. This being 1980s Texas, they're ''very'' relieved when Jeremy introduces new girlfriend Darla at the end of the movie.
* In an early scene in ''Film/IndependenceDay'', Captain Hiller (Creator/WillSmith) ends up with a friend on one knee (demonstrating how to properly kiss ass) and holding a wedding ring box (which had just fallen out of Hiller's locker). At that precise moment, another pilot happens by, sees the situation, and walks off with his hands up in a "don't mind me" gesture.
* In ''Film/{{Dogma}}'', Bethany assumes that Loki and Bartleby are lovers because of some ambiguous phrasing in Bartleby's conversation. Bartleby immediately denies that they're gay, but technically since [[OurAngelsAreDifferent neither of them has a biological gender]] he's not necessarily denying anything, or at least the SlashFic writers would like to think so ...
* The Bollywood film ''Heyy Babyy'' has Riteish Deshmukh accidentally offer a flower to a male party guest. He's highly embarrassed at his faux pas, even more so when the male party guest's confusion gives way to a coquettish smile in return.
* ''Film/LethalWeapon4''. Murtaugh doesn't understand why young detective Lee Butters keeps trying to [[MeaningfulName butter him up]], not knowing that Butters has secretly married his daughter. Riggs, who knows the truth, suggests that Butters is gay. Naturally much HilarityEnsues until Murtaugh discovers the truth, whereupon he punches Riggs in the face for his prank.
* One of the comedic subplots of ''Film/BendItLikeBeckham'' concerned Jules's mother being convinced her tomboyish daughter was a lesbian and her best friend, Jess, was her girlfriend. This is established by having her overhear {{Innocent Innuendo}}s with incredible serendipity. Probably the most notable moment is when she starts coming up the stairs towards her daughter's room, where she's speaking with Jess about her relationship with the football team's coach -
-->'''Jules:''' You don't know the meaning of love!
** This is probably a nod the original script, in which Jess and Jules were actually going to be outright lovers (before Chadha decided that that would be just too alien for a mainstream audience on top of Jess' Indian culture). It's not the [[LesYay only such surviving artifact]] of that plot.
** And played both ways, as Jules' non-traditional interests and GenderBlenderName cause Jess' family to think she's a ''boyfriend'' from her description.
* The guys from ''Film/DeadManOnCampus'' were mistaken for these.
* In ''Film/MyFavoriteWife'' Creator/CaryGrant's character Nick is mistaken for gay after he refuses to sleep with his second wife on their wedding night because his first wife has just returned from the (presumed) dead. Since the movie was made in 1940, they had to do the whole mistaken for gay subplot without ever saying the word "gay" or "homosexual" (in fact, they had to make do without any direct reference to sex of any kind). It's still surprisingly clear, especially when a therapist the (second) wife hired apparently finds Nick trying on a dress.
* This didn't seem to affect them in ''Film/BringingUpBaby'', when Grant goes to the door in Katie Hepburn's dressing gown because there's nothing else to wear, the dignified lady caller wants to know what he's doing in that getup; Grant jumps up in the air, waving his arms, and yells "Because ''I just went GAY all of a sudden!''" While film studios at this time [[http://trueclassics.net/2011/06/27/he-just-went-gay-all-of-a-sudden/ usually got away with having flaming gay characters by contextualizing them]] as "mistaken for gay" or ''Series/{{Frasier}}''-like refined but straight males, in this case and a few others MGM got away with ExactlyWhatItSaysOnTheTin.
* In ''Film/WildWildWest'', the train conductor walked in on Jim West and Artemus Gordon having a discussion on the realistic quality (or lack thereof) of the latter's costume breasts. From the angle the conductor viewed them from, it looked like they were feeling each other up -- and it wasn't at all helped by their declarations of "touch my breasts." The conductor just gets a {{squick}}ed look and mutters "I knew it."
* In ''Film/{{Bernie}}'', the title character snaps and kills his friend Marjorie after she pushes him too far. During a later conversation with one of the townspeople, Bernie asks if it's possible for someone to snap under duress and do something terrible that they couldn't possibly have done under normal circumstances. He's covertly referring to killing Marjorie, but the woman he's talking to thinks he's trying to confess to being gay.
* In the first ''Film/TheNakedGun'' movie, Det. Frank Drebin had just rendered a baseball umpire unconscious to "borrow" his uniform. He removes the uniform, props the umpire over a table and proceeds to undress himself. Moments later, a janitor walks into the room, sees Drebin and the umpire, says "Whoops! Sorry, fellas!" and nonchalantly leaves.
* ''Film/GetSmart'':
** This exchange at the Russian restaurant:
---> '''Max''': There was a guy in the bathroom who's really hot.\\
'''99''': ''(surprised)'' Okay, well...\\
'''Max''': No, no, no, ''radioactive'' hot. Although, yes, he did have a certain rugged quality that some find appealing.
** Max is trying to get Shtarker off a table. A minion passing by sees what appears to be "humping" Shtarker. The minion smiles appreciatively. (This scene was actually cut down for the final version of the film; the deleted part of the scene has the {{mook}} complaining that the boss is allowed that when he isn't.)
* Happens with the teenaged Laser in ''Film/TheKidsAreAllRight'', with the added twist that [[HasTwoMommies his parents are lesbians]]. In actuality, [[spoiler: he and his friend are doing drugs]].
* In ''Film/KickAss'', after Dave is [[spoiler:beaten up and stabbed by thugs and ran over by a car]], his classmates believe him to be gay, because he was found with no clothes on. After hearing this, Katie quickly takes an interest in him becoming her Gay BFF, Dave goes along with it to be close to her. This is a remnant from the comic, which went into more detail and revolved around the fact that he was ''repeatedly'' found with no clothes on in a bad part of town, which lead people to think he was working as an underage prostitute.
* Graeme and Clive in ''Film/{{Paul}}''. Becomes a RunningGag.
* In ''Film/ILoveYouMan'', a guy misinterprets the intentions of Peter (Paul Rudd), which is to say he's just looking for a guy best friend, and promptly kisses him on the mouth.
* ''Theatre/TheChildrensHour'', and the source play, is about two teachers who are sabotaged by a student when she starts a rumor that they're in a gay love affair. Given that this is the early 20th century it's not taken lightly. Parents remove all the kids from the school, they lose a law-suit against the child's grandmother which causes them to become public disgraces around America, their reputation is ruined, and [[spoiler:one of their fiancées dumps them since he believed the lie]]. The twist ending is, as implied multiple times in the film, [[spoiler:that Martha was really gay]].
* ''Film/LoveAndOtherDisasters'' is about a FagHag who does this, causing her to be ObliviousToLove with great comedic effect.
* In the film ''Film/{{Cashback}}'', the main character and his friend Sean (in a flashback) narrowly avoid being caught looking at a dirty magazine, but fail to hide their erections...
-->'''Voiceover:''' After that, Sean's mum always thought we were gay.
* In ''Film/SeventeenAgain'', Maggie concludes that Mike is gay after he is obviously [[{{Squick}} squicked]] by her advances, not knowing, of course, that he's actually the 17 year old version of her father.
* ''Film/PlanB'' manages to be a combination of both this and GayBravado. Bruno catches Pablo, the boyfriend of his ex Laura, checking him out openly at the gym, which leads him to believe that Pablo is bisexual and pretend to be gay/bi-curious himself to seduce Pablo away from Laura so that he can hook back up with her. However, it turns out that Pablo isn't actually bi and was just checking out Bruno because he looked uncannily like a man in a certain photo of Laura's, and is clearly unsure of what to think about his new friend's subtle and not-so-subtle "flirting" with him. [[spoiler:Then all of this is subverted/deconstructed/zigzagged/''something'' when Pablo and Bruno both realize that they've genuinely fallen in love with each other nonetheless.]]
* In ''Film/TheFifthElement'', when Father Vito Cornelius opens his front door to find several hulking {{Mooks}} there to kidnap him:
-->'''Cornelius:''' Weddings?\\
'''Right Arm:''' Not really.
* A PlayedForDrama example in ''Film/HigherLearning'': Remy, a lonely college student, is approached by a young, bald-headed man one night on the campus square. The young man asks Remy to come with him, causing Remy to become suspicious and angrily demand to know if the other guy is a "faggot." As it turns out, [[spoiler: the bald kid is actually a neo-Nazi skinhead who has witnessed Remy being bullied by his black dormmates and thinks he'll make a good recruit to the "white power" cause.]]
* In ''Film/{{Cursed 2005}}'', Jimmy becomes stronger and more confident after being bitten by a werewolf, combined with emitting sexual allure. His closeted bully Bo becomes attracted to him and assumes that Jimmy's change in attitude means he's closeted himself.
* In ''Film/RobinHoodMenInTights'', Robin and his Merry Men encounter [[Creator/MelBrooks Rabbi Tuckman]], who misunderstands the name and asks if they're "feygeles".
* This happens to our heroes in Film/WildHogs every time the [[ManlyGay bike cop]] appears. It doesn't help that whenever he spots or overhears them, they tend to be discussing such matters as "[[HaveAGayOldTime being ridden so hard by Woody]]" or [[NotWhatItLooksLike taking naked baths together]], [[http://www.youtube.com/watch?v=IU2MRgM2Nsk as seen here]].
* Happens in ''Film/FortyTwo'' when Ralph Branca tries to coax Jackie Robinson to shower with the rest of the baseball team instead of waiting for the others to finish.
* In the 2006 film ''Film/DOADeadOrAlive'', Bass Armstrong assumes his daughter Tina is in relationships with Christie and Kasumi when he walks in on Tina and Christie sharing a bed, and later Kasumi giving Tina a shoulder rub. Christie doesn't help when she sort-of hugs Tina and mentions that she sleeps in the nude and wants Tina to do the same. After Bass leaves, Tina kicks Christie out of the bed (literally), and the latter is not nude.
* ''Film/ButImACheerleader'': Everyone but Megan knows that she's gay. Also a very butch girl at the reeducation camp Megan's parents send her to "comes out" as straight, having been mistaken for gay just because of her looks.
* In ''Film/{{Loverboy}}'', Randy is a pizza delivery boy who ends up hooking up with a rich middle-aged Italian woman named Alex. She basically becomes his Sugar Momma. When Randy's father reads some of the letters Alex sends him and notices Randy receiving expensive gifts brought by a guy, he assumes, to his horror, that Randy is gay (Alex being a gender-neutral name). Near the end of the movie, this saves Randy from a NoHoldsBarredBeatdown by three men he cuckolded when one of them (who turns out to be a friend of his father's) remembers Randy's father telling him about his son.
* In ''Film/{{Go}}'', Adam and Zack bicker like an old married couple, causing a girl at the supermarket to think that they're gay. [[spoiler:In a surprise reveal, it turns out that they are.]]
* ''Film/{{Water 1985}}''. Creator/MichaelCaine enters the island's prison and finds its two inmates hiding under the bed as a bomb is about to go off.
-->"Are you two digging a tunnel or committing an unnatural act?"
* In ''Film/MoscowOnTheHudson'', Creator/RobinWilliams' character, who recently defected from the Soviet circus, notices a man, to whom he made a passing greeting, following him down the street. When he confronts the man: "KGB?" "No, GAY. I thought we shared a moment back there."
* In ''Film/CrankHighVoltage'', mob boss Don Kim orders Chev Chelios and Venus into his limo for a discussion. Venus' medical condition makes him go into spasms every once in a while, and the spasms make him look like he's trying to hump Don Kim. Enraged, Don Kim has Venus thrown out of the limo, then comments to Chev, "Your friend, has the gay condition."
* In ''Film/{{Shampoo}}'', Lester asumes George is gay because he's a hairdresser; in reality, George is TheCasanova.
* Casa Nova in ''Film/KayfabeAFakeRealMovieAboutAFakeRealSport'' is suspected of being gay by several of the wrestlers as a result of his obsession with his oiled physique, his refusal to wear pants in the locker room, and his tendency to refuse to let go of certain holds in the ring because "it's hot". [[spoiler:At the end of the film, we meet his beautiful fiancée, Tatiana]].
* In ''Film/MrRight'', Francis fights a hitman in an alley. At one point, Francis gets behind his opponent and grabs him around the waist. A man walks up to them, and quickly walks away while calling them disgusting. Francis comments on the man being homophobic as the fight resumes.
* In ''Film/HorribleBosses 2'', when Nick, Dale, and Kurt break into the office of Dale's old boss Julia, Nick gets dragged into what he thinks is an AA meeting taking place there; however, it's actually a sex addiction meeting, and Nick's improvised description of his "problem" understandably leads everyone else present to think he's gay. However, Nick (the only one of the main trio who doesn't get laid regularly) is happy to go along with it when he finds out that Julia regularly tries to seduce gay men who come to the meetings [[IntimatePsychotherapy with the hopes of]] [[CureYourGays "de-gay-ing"]] them, and he does indeed manage to get laid with her.
* A deleted scene in ''[[Film/FantasticFour2005 Fantastic Four: Rise of the Silver Surfer]]'' has a gag where paparazzi photographs Johnny Storm while he's kneeling in front of Ben Grimm and holding a bouquet.

* ''Literature/TheDresdenFiles'':
** Harry Dresden has frequently been mistaken for [[spoiler: his maternal half-brother]] Thomas Raith's lover, to Harry's dismay and Thomas' great amusement. [[spoiler:Harry uses this to his advantage once when caught snooping in Thomas' apartment. It doesn't help when word gets to the SI division in .005 seconds.]]
** In a case similar to the one of the film examples above, Thomas, when he gets a 'real job' as a hair dresser, deliberately poses as a flamboyantly gay European because there is no such thing as a 'good, high class, straight American' hairdresser.
** The first time that medical examiner Waldo Butters meets Thomas, he immediately thinks Harry and Thomas are a couple--and this is before the events in the first example. Harry tries to convince Butters otherwise. It doesn't work, thanks to Thomas.
* ''Literature/GoodOmens'':
** Happens to Aziraphale and Crowley several times, but mostly to Aziraphale who apparently gives people the impression that he is "gayer than a tree full of monkeys on nitrous oxide."
** Not to mention the fact that Crowley seems to have a habit of calling Aziraphale "angel" with other (human) people present, while Aziraphale calls Crowley "dear" on a regular basis.
** The most notable incident being when Crowley and Aziraphale give [[AwesomeMcCoolName Anathema Device]] a lift in Crowley's Bentley; she worries about whether or not she'll need to use her bread knife to protect herself, but when Crowley calls Aziraphale "angel", [[GettingCrapPastTheRadar she concludes that she hadn't been in danger after all]].
** The most ''humorous'' possibly being when a little girl tells Aziraphale, "You ''are'' rubbish. And probably a faggot."
** Also happens in fanfiction, when fics label Aziraphele/Crowley as slash. The book explicitly states that, being angelic, it takes quite a bit of effort for either of them to ''have'' a gender.
** The screenplay manages to take this even further, with ''nearly everyone in Tadfield with rooms to let'' thinking they're gay and refusing them a room.
*** There's also this (also from the screenplay),
--->'''Madame Tracy:''' Would that be a room each, or do you share?\\
'''Crowley:''' A room each.\\
'''Aziraphale:''' We'll share.
* Fitz and Lord Golden (aka the Fool) in the ''Literature/TawnyMan'' trilogy. More of a PlayedForDrama example, as Fitz is deeply uncomfortable with this and at least a little bit homophobic. It doesn't help that the Fool describes himself as being in love with Fitz, though he also states that his feelings are not sexual. More accurately, the Fool's feelings are not ''necessarily'' sexual. He tells Fitz that he 'puts no limits' on his feelings, but he knows Fitz isn't interested and therefore it wasn't a conversation that ever needed to happen.
* Happens to [[HandicappedBadass Phury]] in one of J.R. Ward's ''Literature/BlackDaggerBrotherhood'' books. [[spoiler: He kisses Rehvenge to shut the latter up after being "accused" of being gay. The Reverend is ''not'' at all thrilled the Brother called his bluff.]]
* In ''The Crystal Cave'', 12-year-old Merlin meets Count Ambrosius, who [[spoiler: turns out to be his father.]] Ambrosius gives him a fine set of rooms, a tutor and a servant. Given Ambrosius' seeming lack of interest in women, Ambrosius' brother Uther, who's always having affairs with women, assumes from this considerate treatment that Merlin is Ambrosius' catamite, even though Ambrosius has displayed no interest in boys either.
* In ''Literature/HarryPotterAndTheOrderOfThePhoenix'' Dudley mocks Harry for yelling "Don't kill Cedric!" [[TalkingInYourSleep in his sleep]], wondering, "Who's Cedric — your boyfriend?"
* In ''[[Literature/BloodyJack Mississippi Jack]]'', a man mistakes Jacky's riverboat tavern for a brothel. When she tries to set him straight, he assumes that the girls "must take care o' business amongst yerselfs", adding that the idea makes him sick.
* Eugenia "Skeeter" Phelan is temporarily mistaken for gay by her own mother, mostly because she's 23 and hasn't had a boyfriend yet.
* Jonah, best friend of the title character of [=MaryJanice=] Davidson's ''Fred the Mermaid'' series is constantly this trope, even by the woman he winds up marrying. He's actually a CampStraight.
* This happens twice in ''Literature/WhyWeTookTheCar'': First at the beginning, when Tschick is convinced Maik is gay, and again, when Isa thinks Maik and Tschick are wearing lipstick after they ate brambleberries.
* In ''Literature/AlexisCarew: HMS Nightingale'', Alexis' first officer Midshipman Villar is attracted to Marie, a single mother Alexis rescued from Giron in ''The Little Ships'', but Villar walked in on them sleeping in Alexis' bed on the way to drop Marie off with Alexis' grandfather. Once he finally manages to work around to saying what he thought, Alexis bursts out laughing and explains that no, both of them are straight and they only slept in the same bed because installing a second bunk in the captain's quarters wasn't practical for either of them (Marie had to be able to get up in the middle of the night to deal with her baby, and Alexis is too short to comfortably climb to an upper bunk).
-->'''Villar:''' You said your sweetheart was French!\\
'''Alexis:''' Yes, French. A Frenchman. A French ''man'', Mister Villar -- a lieutenant in their navy.
* In ''[[Literature/TheFourHorsemenUniverse Cartwright's Cavaliers]]'', one of Jim Cartwright's new employees assumes he's gay because he's rarely dated women. Jim finally becomes irritated enough to correct him that he likes girls, "I just haven't found one that likes me back." (This is mainly because he's severely overweight.)
* Celis in ''LightNovel/UndefeatedBahamutChronicle'' is initially mistaken for a lesbian (and one that DoesNotLikeMen) due to her saying that she's not good with men. In reality, she just doesn't know how to interact with people in general and men in particular.

[[folder:Live-Action TV]]
* The ABC Family movie ''Celeste In the City'' actually has a good use of this. Celeste spends half the movie convinced her interior designer, Kyle, is gay. She's perfectly okay with him seeing her in her underwear and talking about her bad dating life. She decides to set him up on a blind date with her best friend, the very out Dana. Naturally, she's rocked when Dana reveals Kyle is quite straight and astounded as to why Celeste thought he was gay.
-->'''Celeste''': He's an interior designer!
-->'''Dana''': Celeste, just because a guy knows the difference between 50 at Benjamin Moore whites does NOT mean he's gay.
-->'''Celeste''': Isn't that gaydar?
-->'''Dana''': No, that's called stereotyping.
* ''Series/MikeAndMolly'':
--> '''Mike:''' Why is it that at least twice a week, someone thinks we're gay?!
--> '''Carl:''' This one I understand-- [[ItMakesSenseInContext we're cuddling on a mattress.]] But wiping mustard off your upper lip, that's just me being helpful!
** The fact that they argue LikeAnOldMarriedCouple (which Molly even {{lampshade|Hanging}}s) probably doesn't help their case.
** During the Mike/Molly honeymoon episode, Carl receives a temporary patrol partner, a handsome but [[TheStoic stone-faced young man]], whom Carl is his usual overly-considerate self to. Towards the end of the episode, the partner [[spoiler: ''kisses Carl full on the mouth'', having interpreted his overtures of friendship as romantic advances]].
* In ''Series/DropDeadDiva'' Jane is concerned with Stacy's behavior in one episode so has Paul spy on her. He sees her having lunch with a woman and assumes Stacy's a lesbian. Stacy later tells Jane she's not, she wants to have a baby via sperm donor and asked the woman who IS a lesbian for advice.
* ''Series/{{Glee}}'':
** Kurt mistakes new club member Sam as gay. However, little humour comes out of this misunderstanding and it was only to tease viewers who were expecting Sam to be Kurt's new boyfriend.
** Sam is once again mistaken for gay later on in the season after he's caught coming out of a motel room with Kurt.
** And in ''another'' Sam example, when Blaine is buying an engagement ring for Kurt, Sam rushes into the store saying how he wants to support Blaine because he loves him and he wants to help pick out the ring. The saleslady assumes Sam is the guy Blaine is planning on proposing to. Doesn't help that they are extremely physically affectionate towards each other.
--> '''Sam:''' No! I mean, [[IncompatibleOrientation he wants to do me]], but we're just friends.
--> '''Blaine:''' Don't.
--> '''Sam:''' What? You ''do'' want to do me!
* Constable Goody of ''Series/TheThinBlueLine'' suffers badly from this trope. His speech, his mannerisms, his hobbies (gladiators) and many of the things he says give off the distinct impression that he's as gay as Christmas wrapper paper. In fact, he only has one non-stereotypically-gay characteristic: He lusts after women. There have been several misunderstandings involving Goody, such as his uncertainty about "coming out" (he neglected to mention he had been invited out for an illegal drink) and when he misunderstood something Gladstone said...
--> '''Gladstone:''' You know, fellas that talk about it most do it least. I know. I talk about it all the time, and I haven't had any since the days of Harold Wilson[[note]]Harold Wilson was the British Prime Minister 1964-1970 and 1974-1976[[/note]].
--> '''Goody:''' I never knew you were in a gay relationship!
* A surprisingly mature episode of ''Series/MyParentsAreAliens'', Josh, in one of his typical schemes attempts to start a relationship with a pretty, rich girl, but quickly learns she has a terrible personality even he can't deal with, so he asks Sophie to pose as his girlfriend, telling her to morph into someone "I'd want to spend time with". She morphs into his best friend Pete, not understanding the concept of gender and sexuality, and gives a romantic speech about her feelings for Josh, including putting her arm around Josh and referring to him as "my everything", all while in the shape of a boy. The next day the rich girl "outs" Josh to the entire school, encouraging Josh and (the real) Pete to be open about their feelings.
--> '''Pete''' (mildly curious) Does this mean you're my boyfriend now?
* The ''Series/{{Seinfeld}}'' episode "The Outing": Jerry and Elaine and George are messing around at the diner. Jerry and George pretend to act gay when Jerry brings up that people always think that ''he's'' gay because he's thin and neat. And this reporter who is supposed to interview Jerry for a newspaper story overhears them fooling around and thinks that they're actually gay. So when she comes to Jerry's apartment, they [[HeterosexualLifePartners act exactly like they always do]] -- bickering like an old married couple, but with disastrous effects. When they realizes she thinks they're lovers, she leaves in midst of them [[NotThatTheresAnythingWrongWithThat trying to say otherwise]]. More [[ThreeIsCompany mix-ups]] occur, strengthening the reporter's belief, the story gets printed, and HilarityEnsues.
** Also in the episode "The Subway": Elaine tells a lady on the subway that she is the best man at a lesbian wedding and the lady mistakes Elaine for a lesbian herself and is {{Squicked}}.
---->'''Elaine:''' You don't understand!!!! I'm not a lesbian!!! I hate men but I'm not a lesbian!!!!
* ''Series/{{Frasier}}'', on several occasions, the [[PostModern meta]] joke is that the actors playing them ''are'' gay.
** In one episode a series of misunderstandings based on the initial assumption that Frasier is gay leads to a character concluding the entire family is. Another has Marty acting gay for Frasier's sake (he's interested in a woman who's trying to matchmake for her gay uncle).
** Bulldog Briscoe (Dan Butler, who is gay) in ''Fortysomething'':
-->'''Carrie''': (thinking Bulldog is overcompensating) Is he gay?
** Niles Crane (David Hyde Pierce, who is gay) in a few episodes, including ''The Matchmaker'':
-->'''Tom''': (after learning Frasier isn't gay) But Niles - come on!\\
'''Frasier''': No, I'm afraid not.\\
'''Tom''': Huh... so wait a minute, this Maris guy he kept mentioning is a woman?\\
'''Frasier''': Well, the jury's still out on that one.
** Martin Crane (John Mahoney, who is gay) in a few episodes, including the aforementioned ''The Matchmaker'' and the plot to ''Out with Dad'':
-->'''Martin''': (after realizing Edward is attracted to him) But what if he asks me for a date?\\
'''Frasier''': I have news for you: You're ''on'' a date!
** It leads to a situation in which Niles has to pretend he's his father's lover to reinforce the illusion that Martin is gay, leading to this classic exchange:
-->'''Frasier''': Niles, Emily just kissed me in the bedroom and now she's leaving. I have never been so embarrassed in my life.\\
'''Niles''': ''You're'' embarrassed?! They think the best I can do is an old man with a cane!
** Finally, Niles "breaks up" with Martin:
-->'''Niles''': You're always asking, badgering, spying on me! Well, I won't be suffocated anymore. I'm tired of being your trophy boy! It's over, you hear me? Over! (haughty sniff) And I'm ''keeping'' the jewelry!
** Also in "Ski Lodge"
--> '''[[StraightGay Guy]]''' (Who thought that Niles was flirting with him) to Martin: Maybe the Rum is clouding my judgement, but Niles... is he...
--> '''Martin''' (Thinking he is talking about Nile's crush on Daphne): No, stop right there. You got it, he got it bad.\\
'''Guy:''' Really?! This is not an uncomfortable subject for you?\\
'''Martin''': No, no no - Niles have had ''those'' feelings for ''years!'' Of course, I didn't approve of them during his so called marriage, but now when he is single, I say let do what makes him happy! I say go for it!\\
'''Guy''': [Wistfully] You are a wonderful father.
** Leading later to:
--> (Frasier walking into the room where Guy is naked and waiting for Niles, expecting to see Daphne's friend who he's been chasing all episode)\\
'''Guy''': You are not the Crane I want.\\
'''Frasier''': You're not even the ''sex'' I want.
** In ''The Doctor Is Out'', flamboyantly gay opera director [[Creator/PatrickStewart Alistair]] is introduced to Niles and Daphne:
-->'''Daphne:''' And I'm Daphne, Niles' wife.\\
'''Alistair:''' ''(amused)'' No.\\
'''Niles:''' We're expecting.\\
'''Alistair:''' Can't say I was.
** Later:
--> '''Frasier:''' He does not think I'm gay.\\
'''Niles:''' He thinks ''I'm'' gay, and I'm standing next to my pregnant wife.
* This ploy was actually a plot device and a RunningGag on ''Series/ThreesCompany'' It was actually intentional on the roommates' parts, in that that is the only way that a single man and two single women would be able to share residence was that the Ropers wouldn't allow it unless the man was gay. Jack was ready to drop the lie when Mr. Furley took over, but the same issue arose, forcing him to resume the charade. It was abandoned late in the series life when Jack "came out" as straight.
* ''Series/WKRPInCincinnati'': Meek weirdo Les Nessman is mistaken for gay by a pro athlete. This being the 70s, he threatens suicide until the accusation is retracted. Even it being the 70s doesn't excuse Les's overreaction though, which was the point; the character was the archetype of an old-time Red-baiting conservative who ''would'' jump out the window if somebody questioned his sexuality. Johnny or Venus would have just laughed it off. What was shocking about it for the 70s was Herb Tarlek telling Les that he ''didn't care'' if Les was gay.
* ''Series/BrooklynNineNine'': In the episode "The Party," one of Kevin's party guests mistakes [[ThoseTwoGuys Hitchcock and Scully]] for a gay couple due to their HeterosexualLifePartners status.
* ''Series/BuffyTheVampireSlayer'':
** In the episode "Phases" (Season 2, Ep. 15), Xander believes that local JerkJock Larry is a werewolf and tries to get him to confess, saying that he "knows what Larry's been doing at night" and that he went through something similar (alluding to the time he was possessed by a hyena spirit). It then comes out that Larry is not a werewolf, but he is gay, and now he thinks that Xander is too. The mistaken sexuality continues in the episode "Earshot" (Season 3, Ep. 18).
** The episode "Gone" (Season 6, Ep. 11) where Buffy receives a visit from a social worker about Dawn. Buffy's forgetfulness of a certain redhead leads to the following exchange. Worth noting is that it's hard to say if Ms. Kroger really believed Buffy.
---->'''Buffy''': That's Willow. She, uh, she kind of lives here too, actually.
---->'''Ms. Kroger''': Oh, so you live with another woman.
---->'''Buffy''': [[BuffySpeak Oh! Oh, it's not a, a gay thing, you know, I mean, well... she's gay, but, but we don't ... gay.]]
** In Season 9, Whistler leaves a message for Angel to meet him at a disclosed location on their "anniversary." One of Giles' aunts immediately says "''That's'' why Angel hasn't hit on me."
* ''Series/{{Angel}}'':
** In the episode, "Disharmony", Cordelia mistakes Harmony as being gay, when Harmony is actually trying to tell her she is a vampire.
--->'''Cordelia''': [on phone with Willow] Ohhh! Harmony's a vampire? That's why she--Oh, my God, I'm so embarrassed. (laughs) All this time, I thought she was a great big lesbo...! ([[{{Beat}} long pause while Willow says something]]) Oh, yeah? Really? Well that's great. Good for you!
** Happens so much with Wesley that it could be considered a RunningGag.
*** In ''Expecting'' (1x12), Cordelia has a couple of friends come by the office. Angel and Wesley start talking to each other to distract from Cordelia having a vision and Wes flings his arm around Angel's shoulders in what he intends to be a display of brotherly affection, only to have one of the girls mutter "The good ones are always gay." {{Lampshade|Hanging}}d very funnily later in the episode, when Angel and Wesley are talking and Wesley asks if Angel thinks he has a shot with the (gorgeous) girls. Angel says he thinks so, which leads to this.
--->'''Wesley:''' What about them thinking we're gay?
--->'''Angel:''' It adds mystery.
*** In ''Carpe Noceem'' (3x04), An old man possessing Angel's body hears about a romantic entanglement with someone named "Fred," looks down at what Angel is wearing, and mutters, "Obviously." This also causes him to mistakenly try to break up with "Fred" (actually Wesley) before he figures out that [[GenderBlenderName Fred is a girl]] (Winifred).
*** In ''Harm's Way'' (5x09), employees at Wolfram & Hart are discussing who they think is interested in Fred. Harmony suggests Wesley but is shot down because there's an established belief at the firm that Wesley is gay.
** In the second episode of the series, the group is questioning folks at a singles bar - we see Angel anxiously telling a guy "No, really, I wasn't hitting on you!"
** When Kate Lockley's father mistakes Angel for her boyfriend, he says he's glad because he suspected she was a lesbian.
** Done twice over by Faith who mistook Lilah for a lesbian when Lilah tried to recruit Faith to work as an assassin for them. Faith apparently accepted "the pickup" in order to mug her.
-->''[Lilah and Faith leaves a club.]'' \\
'''Faith:''' We can go and talk, but I'm not much of an talker. I'm more of a doer. \\
'''Lilah''' ''[smirks]'' I think you might have misunderstood my intentions. \\
'''Faith:''' No I think you misunderstood mine. ''[slams her up against a wall and grabs her wrist.]'' I like that watch.
* Subversion: In an episode of ''Series/{{Cheers}}'', Norm -- whom it is revealed has a native talent for interior decor -- decides to pursue that field instead of his previous career. However, he discovers that he has to pretend to be [[FlamboyantGay "stylish"]] in order to be taken seriously as a decorator.
* A character from ''Series/UglyBetty'' (a straight fashion designer) has this dilemma.
* Matt Damon's character in ''Series/WillAndGrace'' is a straight man in a gay glee club.
* A mischievous girl convinces both Reese and Malcolm that the other is gay in ''Series/MalcolmInTheMiddle'', which leads to some amusing conversations.
** Hilariously, the [[AmbiguouslyGay evidence for Reese being gay really stacked up.]]
** This episode also led into a CrowningMomentOfHeartWarming, since the brothers, instead of teasing each other as it would have been expected, actually accept the fact that the other one is gay and try to support each other.
** Another example is one episode when Francis is in military school helping out with a beauty pageant(of course, he's only helping to meet some girls). When he is backstage with one of the girls, she says something to the effect of, "It's okay if you're gay. We're a lot more open here[Alabama] than you think." He milks this for all its worth to be able to feel up the girls without them noticing. Eventually, he slips up and tells a girl she's sexy. He covers it up by saying that when he looks at her, he feels like maybe he could change. They are talking, and just as it looks as if they're going to kiss, the scene switches to him at a church service for "curing" gayness.
* A running joke in ''Series/{{Friends}},'' with Chandler the target. Originally from a first season episode "The One Where Nana Dies Twice", where we discover most of the friends thought he was gay when they first met him. Apparently he has "a quality". His gay co-workers disagree.
** The one where Chandler uses a subliminal motivational tape so he can quit smoking, but it's for women. Also the one where he and Joey are mistaken for a couple when they are seen with baby Ben.
*** Chandler and Joey get this a lot; half of Chandler's 'gayness' comes from the way that him and Joey are frequently portrayed as a married couple, with GilliganCut style jokes to this effect.
** Brought up in ''Series/{{Joey}}'' when Gina tells Joey that he and Chandler should have moved out to LA years go because it has a "very friendly gay scene". Joey responds that he and Chandler are not a gay couple.
** Also happens to [[HopelessSuitor Gunther]] in the HalloweenEpisode where he ran out to pick up more candy because of Rachel being a pushover and handing out too much. She calls him sweet and tells him "[[ObliviousToLove some day you are gonna make some man the luckiest guy in the world]]."
* In Season 5 of ''Series/HowIMetYourMother'' Robin's boyfriend at the time, Don thought that Ted was gay because of some effeminate interests like calligraphy, Project Runway, and cooking. That is until he found out Ted is Robin's ex.
** When Marshall is on the phone in the narration of a {{Whole Episode Flashback}}, he mentions the part where Ted tells Robin his big secret (that he is in love with Zoey) and Marahall's mother who is eavesdropping on the other line immediately shouts out "HE'S GAY!!!".
** In another episode, [[spoiler: when Robin is trying to sell Barney's apartment, Ted and Marshall come in together (to pretend to be prospective buyers to drum up interest) with baby Marvin. One of the women looking at the apartment misinterprets and assumes [[HasTwoDaddies he's their son]]. They decide to roll with it (partly because Marshall is feeling neglected by Lily at the time)]].
* ''Series/BlackBooks'': Bernard accuses Manny of being gay due to his interest in interior design, specifically nice lamps. Manny protests he likes women (as well as lamps) but admits that he had thought Bernard was gay. Bernard says that he thought so himself, but was put off by the expected high standards of personal hygiene "and all that...''dancing!''"
* ''Series/{{Supernatural}}'':
** Happens to Sam and Dean more than once. It started as a random joke, and has now become a running FandomNod. In one episode they pretend to be interested in buying a house, and two realtors, on separate occasions, mention that "we accept homeowners of any race, religion, color, or sexual orientation."
** Also happens in the one with the little girl at the old hotel: when they go to check into the hotel, the owner mentions that "We get a lot of gay couples down here because of the great antiques shop."
*** Leading to this exchange later on:
---->'''Dean:''' Of course, the most troubling question is "Why do these people assume we're gay?"\\
'''Sam:''' Well, you ''are'' kind of butch. They probably think you're overcompensating.
** Happens again in the fourth season premier: when [[spoiler: Dean comes back from the dead and proves to Sam it's really him]] they embrace tearfully and the girl Sam was with earlier says "So you guys are..." before Dean interrupts her with "Brothers." Made funnier by the fact that the girl is later revealed to be [[spoiler:Ruby]], knows exactly who they are, and was doing it just to mess with them.
** And of course the lovely episode when Dean asks for "two queens" at the motel and the lippy kid behind the counter mutters "I bet."
** The fact that ''Supernatural'' exists as an in-universe franchise (as a book series penned by a prophet of God [[spoiler:who is later revealed to actually ''be'' God]]) leads to many hilarious meta episodes. The in-universe fandom seems to be just as obsessed with HoYay as the real-life fandom.
*** In "[[Recap/SupernaturalS05E09TheRealGhostbusters The Real Ghostbusters]]", Sam and Dean do some ghost-busting at a ''Supernatural'' convention, assisted by a pair of Sam and Dean cosplayers. The convention has an entire panel on "Homoerotic Subtext in ''Supernatural''", and at the end of the episode the cosplayers are revealed to be an actual gay couple.
*** In "[[Recap/SupernaturalS04E18TheMonsterAtTheEndOfThisBook The Monster at the End of This Book]]", Sam and Dean realize OhCrapThereAreFanficsOfUs:
---->'''Dean:''' There's Sam Girls and Dean Girls and... what's a slash fan?\\
'''Sam:''' As in Sam-slash-Dean, together.\\
'''Dean:''' Like ''together'' together? They ''do'' know we're ''brothers'' right?\\
'''Sam:''' Doesn't seem to matter.\\
'''Dean:''' Well that's just sick!
*** Dean/Castiel gets a nod in "[[Recap/SupernaturalS10E05FanFiction Fan Fiction]]", Sam and Dean investigate a musical adaptation of ''Supernatural'' at an all-girls school. Dean is a bit concerned when he sees the girl playing him and the girl playing Cas making out, but the writer/director assures him that it's not part of the play, those two girls are actually dating. However, Dean's relief doesn't last long as she goes on to talk about how the play "explore[s] the nature of [[PortmanteauCoupleName Destiel]] in Act 2".
** In the season 8 episode "Bitten", the college students the episode focuses on assume that Sam and Dean (who they think are FBI agents) have a "workplace romance" going on.
* British sitcom ''{{Series/Extras}}'' has Andy Millman meet an old school-friend of his who, despite being successful, is still a bigoted JerkJock who constantly makes jokes about Andy being gay because he has never seen him chatting up a girl. At the same time Andy is trying to gain recognition in the theatre and gets a starring role in a play by Creator/IanMcKellen. He has to play a gay role, something that he appears to get to grips with after his initial annoyance at finding it out, but unfortunately for him his school-friend gets tickets for himself and several of his other homophobic old friends. They also happen to catch him in the dressing room with [=McKellen=] with his trousers down, as [=McKellen=] calls for some vaseline to cure Andy's non-existent ulcer that he tried to get out of kissing on-stage with.
* An episode of the Glaswegian sitcom ''Series/StillGame'' was built around this; the NosyNeighbor Isa happens to catch Victor in Jack's flat very early in the morning, not to mention with his trousers down and talking about finding "arse cream" (the reason being they had opened a door between one another's flats so that they could share their cable television and could avoid Isa in the first place). After she gets over the "gossip-overload", word spreads around. Everyone is more or less tolerant over it, but eventually the entire community is up on the misinformation. Bobby the barman takes things too far by playing ABBA and having everyone in the bar dance to make Jack and Victor feel at home... This only leads the two of them to suspect that ''Bobby'' is gay.
* Dennis Finch from ''Series/JustShootMe'' ''wishes'' he were mistaken for gay, as usually he is [[DudeLooksLikeALady mistaken for a woman]], much to his chagrin. There was one episode where Dennis was mistaken for gay by his own father, but this is not who he wanted to make the mistake. The closest he got was to be mistaken for a lesbian, which actually worked to his advantage... until his true gender was exposed.
** Maya was mistaken for lesbian by a model, a situation which Dennis tried to take advantage of.
** In yet another episode, Nina is dating a flamboyant magician. When confronted by Jack and Elliott, she reveals that she obviously knows he's gay. However, when she confronts him, he responds with "I'm not gay, I'm British!"
*** That statement was also used by one of the main characters on the short-lived WB sitcom ''Left of Center''.
*** And also as a punchline by Bakura in ''WebVideo/YuGiOhTheAbridgedSeries''. Of course, given that this version of Bakura apparently is repulsed by girls and has magical Gaydar powers, one wonders if he doth protest too much...
*** Bakura frequently explains "I'm not gay, I'm just British", while the demon possessing him points out "I'm not British, I'm gay".
* ''Series/{{JAG}}'': Admiral Chegwidden's yeoman Petty Officer Jason Tiner is mistakenly assumed to be this "People v. Gunny". This was back in the days of ''Don't Ask, Don't Tell''.
* A bizarre variant in ''Series/ThirdRockFromTheSun'': Sally ends up with a guy who's the "most sensitive man she's ever met" and would be very obviously gay to anyone who was actually from the planet Earth. He seems to believe that she's simply a transvestite or transgender woman, and, despite the fact that he normally has little interest in "people like you", interprets her confused stories about her military background and current desire to "just blend in" as stories about a struggle against homophobic oppression. A series of comical mishaps lead him to think that the whole family is gay. The man only realizes that Sally is a woman when he helps her out of her dress and then promptly breaks up with her.
** In another episode, a gay man comes out to Dick, unfortunately describing himself as being "from another world". Dick, of course, thinks he's another alien and [[MistakenConfession immediately says "so am I!"]] Pretty soon, Dick is hanging out at what he thinks are "alien bars" and enjoying the camaraderie there. He only discovers the truth when Mary finds out and he thus tries to convince her that he's straight. After she leaves the room, he says to himself "I'm an alien. Oh, God, I wish I was gay!"
** And then there's the episode in which Sally [[StatusQuoIsGod almost]] got married. While preparing for the wedding, Tommy discovers his never-again-seen love of doing artsy-crafty things, causing his girlfriend August to spend the whole episode worrying that he's gay.
** In a first-season episode, Harry encountered a CampGay man played by Phil Hartman who mistook Harry for a fellow homosexual. When Harry talks about how Dick is his "High Commander" and wants him to fit in more, the man replies "Oh, I was in a relationship like that once."
** Oh, and did we mention TheDocumentary episode in which Dick [[EmbarrassingCoverUp covers a slip-up]] by inventing that Sally is a lesbian and she's forced to play along?
** In the episode where Dick and Don become friends, Dick is outraged to discover Don going out with another friend and promptly delivers [[DoesThisRemindYouOfAnything what sounds very much like a break-up speech]]. After Dick leaves, Don's friend says "It's okay, Don, I understand. I'm gay, too!"
** What about the episode where Dick dressed in drag to infiltrate a women's discussion group and they all thought Dick and Mary were lesbians?
* In the second episode of ''Series/RosemaryAndThyme'', the two main characters decide not to tell the local police what they know, because he thinks the two ladies are a couple.
* In the ''Series/ThirtyRock'' episode "Blind Date", Jack sets Liz up with the "brilliant plastics engineer/lesbian" Gretchen Thomas, leading to the top page quote. Matters aren't helped when Liz, being the neurotic wreck that she is, decides to call Gretchen and have a nice chat with her anyway. The others encourage Liz to hook up with her, but Liz insists that they're "just friends, like Oprah and Gale". Given the existence of Liz/Gretchen {{fan fic}}tion, it seems a sizable number of {{shipp|ing}}ers didn't buy that. Liz offered to, if they were both still single in a few years, live together and if it would make things easier, let Gretchen "do things" to her.
** When a reality show starring Tracy's wife filmed in the studio, Jack started reminiscing on camera about his college athletics, unconsciously making it all sound like gay sex (which the show immediately picks up on) - Grizz and Dot Com are very much aware of how it sounds and encourage him to keep talking.
* The title characters on ''Series/KateAndAllie'', two single moms sharing an apartment, were mistaken for lesbians by their lesbian landlords, then have to play along to avoid getting thrown out because the landlords don't think they'd qualify as one "family". After a PatrickStewartSpeech about Tolerance, they're allowed to stay.
* We can't forget Dana Carvey's ''Series/SaturdayNightLive'' skit "Lyle the Effeminate Heterosexual".
** Or Chris Kattan as "Mango".
*** Alec Baldwin did a skit where he recorded his voice on an answering machine and realised his voice is seriously effeminate.
* ''Series/{{Scrubs}}'': JD and Turk. People just don't understand their [[HeterosexualLifePartners Guy Love]].
** "He's mine; I'm his / There's nothing gay about it in our eyes."
*** Also that episode with the gay white patient with a black boyfriend.
** There was also [[http://www.youtube.com/watch?v=82UfuSMVOvo Sunny and Denise's skit in the intern play]]. It's probably one of television's only purely LesYay moments with straightforward HoYay implications.
* ''Series/{{Psych}}'': Shawn and Gus. Sometimes Shawn annoys Gus by going along with it as a joke. One example of many, this one featuring Shawn's high school crush at their class reunion:
-->'''Abigail''': Oh, wait, I get it. You guys are dating. You're together. Everything makes sense.
-->'''Gus''': We are not dating.
-->'''Shawn''': Are you kidding me? He was voted "Most Likely to Succeed". You think he's gonna date me?
* Frequently appears in the revived series of ''Series/DoctorWho'', having started during (openly-gay) showrunner Creator/RussellTDavies' tenure and continued by subsequent production teams;
** In "Daleks in Manhattan", Martha laments The Doctor's disinterest in her to Tallulah, prompting the comment, "Oh! I should have realized. He's into musical theatre, huh? What a waste."
** In "Turn Left", Rose is trying to get Donna to remember the way the world should be, and Donna gets the wrong impression. "Blonde hair might work on men, but not on me."
** In "Time Crash", after the Tenth Doctor mentions his old nemesis' latest return BackFromTheDead, the Fifth Doctor inquires whether the Master still had "[[BeardOfEvil that rubbish beard]]" this time around.
---> '''Tenth Doctor''': No, no beard this time... well, a ''[[TheBeard wife]]''.
** Bill has been mistaken for straight several times. In Knock Knock one of the boys tried to flirt with her, in Extremis her foster mother was saying she had srict rules about her bringing men back.
** In "Let's Kill Hitler", it's revealed that Amy assumed Rory was gay for ''years'', because having seen him practically every day since they were young, she couldn't name [[ObliviousToLove a single girl]] he'd shown the ''slightest'' [[IResembleThatRemark bit of interest in]]. It takes her a while to finally get it.
** In "Closing Time", the Doctor gets mistaken for gay, when he goes out shopping/Cybermen hunting with a baby and Craig. (They ''were'' being rather cuddly). The Doctor doesn't appear to notice, actually considering the word "Partner" as a replacement for "companion". Later, he claims to be madly in love with Craig and tries to kiss him, as a distraction.
** The Eighth Doctor is mistaken for gay by at least two ''AudioPlay/BigFinishDoctorWho'' companions.
* An episode of ''Series/SexAndTheCity'' had Charlotte dating a pastry chef with a great many "feminine" qualities, including jumping up on a chair when he saw a mouse. Charlotte and the girls think he's closeted gay. Charlotte asks him if he is and he says, "I'm a 35 year old pastry chef who lives in Soho. If I was gay, I'd ''be'' gay."
* Roommates Leonard and Sheldon of ''Series/TheBigBangTheory'' continue to introduce themselves as "living together" even though everyone initially misinterprets this, including their new next-door neighbor Penny and their friend Raj's parents, who think they're "like Haroon and Tanvir." Leonard protests and explains the situation, although later as Sheldon runs to get their special-edition DVD of ''Fiddler on the Roof'' he remarks to himself, "Maybe we ''are'' like Haroon and Tanvir."
** Sheldon was also able to get a date with far more ease then his friends, although at the time he was trying to find a man to set Penny up with, and he didn't realize the miscommunication. Hilarity ensued.
** Raj and Howard have this happen to them all the time. There was the time Leonard's psychologist mother said they were in an ersatz homosexual relationship, and they start arguing like an old married couple. Both are straight, but their romantic exploits tend to be...less than successful.
** This has become a RunningGag with Raj. In one episode, he invites a childhood friend, Lakshmi, to his apartment for dinner. Lakshmi suggests that they should get married because she's a lesbian, she assumes he's gay and they can "beard" for each other to keep their parents from finding out.
** In a RealitySubtext example, some first-time viewers note Sheldon's fussy mannerisms and mistakenly believe that the cast consists of a "regular guy," an Indian, a Jew, and a gay guy. This became HilariousInHindsight when Sheldon's portrayer, Jim Parsons, publicly announced his homosexuality.
** While Skyping with his parents in India, Raj's mother complains "The closest thing we have to a daughter-in-law is that little Jewish boy!"
* Frank Fontana of ''Series/MurphyBrown'' is almost always a victim of this. It's delightfully ironic, considering that he's always trying to be the ChickMagnet.
* In ''Series/PushingDaisies'':
-->'''Vivian:''' Charlotte was such a nice girl... do you like girls?
-->'''Ned:''' ...Yes.
-->'''Vivian:''' Didn't want to assume.
* In ''Series/TheBasilBrushShow'', Mr. Steve works up the courage to ask a long-haired women for a snogging. He fails to notice the long-haired women being replaced by a long-haired man. The man, when asked by Mr. Steve for a snog, turns and punches Steve. Hilarious. It did anger same gay-rights activists, though. It wouldn't have attracted so much anger if it ''had'' been hilarious. It wasn't even that funny when it was tried the first time, back in about 1972.
* ''Series/RemingtonSteele'': Steele is searching a missing man's hotel room when the man's ex-girlfriend happens to come in. Since the boyfriend had mentioned he was dating someone new, she assumes he meant Steele, and laments, "Why is it always the good-looking ones?"
* ''Series/CarolineInTheCity'' had Richard finally managing to get his work in a gallery. Unfortunately, he then discovers that said gallery only sponsors gay artists. He initially tries going on with the charade, but eventually confesses. This is particularly amusing because this is not the only time in the series someone mistakenly thinks Richard is gay, and though he isn't (he's the main character's love interest), Malcolm Gets, who plays Richard, is.
* In an episode of ''Series/StElsewhere'', a hotel receptionist assumes that Drs. Craig and Westphall are a couple.
* This is a running joke on ''Franchise/LawAndOrder'': two detectives walk into a store or hotel to question someone and are promptly identified as "together."
** Occasionally, the detectives masquerade as gay in order to pin down a gay suspect or witness.
** In a variation on the theme, a witness once tried to pick up very straight and very conservative Det. Curtiss, much to the amusement of Lenny Briscoe.
** One episode of ''Series/LawAndOrderSpecialVictimsUnit'' had a witness give Olivia his home phone number and suggest that she give his bisexual wife a call.
** This actually becomes an [=SVU=] RunningGag, as people continually mistake Olivia for gay. The section of the fandom who think she's in love with HelloAttorney Alexandra Cabot lap this up.
*** Then there's this delightful exchange in "P.C." after a woman tried to kiss Olivia:
-->'''Benson:''' El, do you ever get a gay vibe from me?
-->'''Stabler:''' ''(beat)'' Would it matter if I did?
-->'''Benson:'''...You're not answering the question.
** Fin and Lake were mistaken for a couple while trying to get eyewitness statements without revealing that they were cops. Lake decided to roll with it by putting his hand on Fin's thigh. [[DeathGlare The look on Fin's face...]]
* In an episode of ''Inspector Series/{{Lewis}}'', Lewis and Hathaway are mistaken for a couple by a school headmaster, who assumes they're looking for a school for their child.
-->'''Hathaway:''' (takes Lewis's hand) Darling, I think you should explain.
* Korean Boy Band, Music/DongBangShinKi. In one of their mini-dramas, a member mistook another member's accidental double entendre for the real deal. [[spoiler:Turns out the "homosexual" in question just wanted to kiss-up to him for breaking his possession]]. Needless to say, many [[YaoiFangirl girls loved it]].
* From an episode of ''Series/TheDrewCareyShow'':
-->'''Steve Carey:''' I play for the other team.
-->'''Lewis Kiniski:''' I knew it, he's gay.
-->'''Steve Carey:''' No, I mean the other softball team.
** There's another episode where, after Oswald defeats a bruiser-type fellow driver named Joe in a boxing match, the two start hanging out together. Joe starts taking Oswald out to dinner and lavishing him with gifts, including clothes. It takes the rest of Oswald's friends to point out that, if Joe's buying him clothes, then the two are dating. Oswald confronts Joe about this, and Joe is shocked to learn that Oswald isn't gay, and points out that the only reason Oswald won the boxing match was that Joe couldn't hurt his "pretty face". Their conversation also clues Oswald to the fact Joe isn't the first male co-worker that he's been dating.
* In ''Series/AllTheSmallThings'', Olive's friends suspect that she's a lesbian because of her unfeminine appearance. In actual fact, [[spoiler: she avoids wearing skirts in order to conceal her [[ArtificialLimbs prosthetic leg]].]]
* On ''Series/ParksAndRecreation'', Leslie gets a butch haircut at a men's barber, then goes to a political banquet holding Ann's hand. Ann knows what everyone is thinking, but Leslie remains hilariously oblivious.
-->'''Ann''': This is my evening... I'm Leslie's trophy wife.
* There's a lot of HoYay in the prison drama ''Series/{{Oz}}'', so when Ryan O'Reilly runs into his recently-convicted brother in the prison cafeteria and embraces him, the guard immediately shouts at them to knock it off.
-->'''O'Reily:''':"He's my brother!"
-->'''Guard:''' "Oh yeah? With hair like that he's more like your sister!"
* In ''Series/{{Wings}}'', Joe and Brian were celebrating and kissed each other on the lips. Everyone else looked at them weird.
* In ''Series/TenThingsIHateAboutYou'', based on the 1999 film, Bianca mistakes her friend Cameron for being gay, [[spoiler: despite him being madly in love with her]], due to the fact that he's 'so nice' and watching ''Series/ProjectRunway'' [[spoiler: though Cameron admits it's only to see Heidi Klum]]., and, in the episode, he dressed rather gay-like to get Bianca's attention. And it did. Just not the way he planned.
* In the ''Series/CornerGas'' episode "Doc Small", Brent is mistaken for gay (and thought to be involved with a man into bestiality) as a result of Hank, a logic puzzle and a $100 bill (ItMakesSenseInContext). He doesn't notice.
* An episode of ''Series/StrongMedicine'' has Peter thrown when his mother comes by for a visit, apologizing for cutting him off but now has "finally accepted" he's gay. Her "reasoning" is that Peter is a nurse in San Francisco who doesn't have a steady girlfriend. The rest of the staff find this hilarious as they know Peter is a constant ladies' man. Peter tries time and again to explain he's straight but finally gives up as his mother seems to be happy with "accepting" him.
* At the end of the very first ''Series/TwoAndAHalfMen'' episode, the brothers are mistaken for life partners while buying cereal. Then later in the series, they had to pretend to be gay for one of Charlie's clients who thinks Charlie's gay. Then when they're buying an engagement ring for Mia, Alan ends up doing most of the talking and the salesman assumes it's for Alan.
* A ''Series/SpinCity'' episode where Mike interrupts one of the Mayor's interviews, referring to himself as "TheManBehindTheMan". The interview was for a gay newspaper.
* ''Series/GroundedForLife'' when Shawn took his kids to the amusement park. It was "Gay Day" there and everyone was wearing tanktop and jeans. Guess what he was wearing...
* This happens pretty often on ''Series/TheNanny'':
** In "Oy Vey, You're Gay", Maxwell hires publicist Sydney Mercer to improve his image. Sydney is an attractive young blonde woman, and this makes Fran and C.C. jealous. Fran thinks she wants to be with him, and decides to try and wish them the best of luck as a couple, but Sydney tells her she's not interested in Maxwell: "It's his gender!". Fran misinterprets this before she tells her "Fran, I'm gay!". Fran then shouts "Oh, thank God!" and hugs her, but becomes perturbed when she stops hugging and the publicist doesn't:
-->'''Fran:''' I'm letting go and you're not. Why?
-->'''Sydney:''' Aren't you gay, too?
-->'''Fran:''' Me? No!
-->'''Sydney:''' I just assumed. You're over 30, never been married, there's no man in your life...
-->'''Fran:''' [[NotThatTheresAnythingWrongWithThat Oh honey, I'm not gay. I'm just pathetic!]]
** In "A Fine Friendship", Fran is convinced the male nanny for Gracie's friend is gay. The fact he's also a struggling Broadway actor backs up her assertion, until he and Fran share a passionate kiss. Fran gets upset. She asks "You mean you're ''not'' gay?!"
** In "Pishke Business", Fran has to pretend she's C.C., Maxwell's business partner, [[ItMakesSenseInContext after C.C. unwittingly attacks their play's biggest investor]], and to prepare Fran, C.C. gives her a big binder with biographical info:
-->'''C.C.:''' (''flipping through pages'') Where I grew up, went to prep school, when I came out...
-->'''Fran:''' [[HaveAGayOldTime You came out?!]] So what are you [[StalkerWithACrush always sniffin' around Mr. Sheffield for?]]
-->'''C.C.:''' My coming-out party, Miss Fine.
-->'''Fran:''' I know, I heard you. You know, now you and your special friend can dance together at Disneyland!
* From ''Series/TrueBlood'': While Bill is trying to buy some women's clothes (for Jessica), a shop assistant tries to pick him up and doesn't listen when he says he's not interested... not until Eric appears and wants Bill to admire his new haircut.
* ''Series/FlightOfTheConchords''. Seriously.
* This happened several times on ''Series/{{Reba}}''.
* The subplot of the ''Series/{{House}}'' episode "The Down Low", when a new neighbor refuses to believe House and Wilson aren't a couple. It doesn't help that House decides to run with it. In order to get close to the (pretty, female, unsuspecting) neighbor.
* Happened once in ''Series/SanfordAndSon.'' Lamont and Rollo accidentally go into a gay bar. When Bubba sees them enter and tells Fred, he starts trying to figure out if his son is really gay. Later, Fred and Bubba try to catch the two in the same bar...and ''Rollo'' sees them go inside, making Lamont think his father's gay. HilarityEnsues.
* ''Series/{{Sherlock}}'':
** This happens to Holmes and Watson a few times in the first episode alone. Additionally, they also mistake ''each other'' for gay when Holmes answers Watson's questions regarding his social attachments with "[[CelibateHero girlfriends are 'not really my area']]," prompting the latter to ask about boyfriends; Holmes misinterprets Watson's awkward attempts at making conversation as a sign of romantic interest, and tries to 'let him down' politely.
** This has now become something of a RunningGag, usually as a means to explain why [[TheCharmer John]] can't seem to hold onto his girlfriends. People who have mistaken Sherlock and John for gay by the end of Series 2 include: several of John's girlfriends (who promptly ditch him), the British press, Sherlock's arch-nemesis Moriarty, Sherlock's brother Mycroft, their landlady Mrs Hudson, a gay couple who owned a hotel they were staying in, Sherlock's single-episode crush Irene Adler, a therapist John attempted to flirt with, Angelo the proprietor of their favourite restaurant... It doesn't help that Sherlock, who honestly doesn't give a damn about public opinion, never bothers to deny it, leaving John looking like he's [[HaveIMentionedIAmHeterosexualToday protesting too much.]]
** By the third series, Mrs Hudson's reaction to John revealing he's about to get married is to be shocked that a): it's to a woman and b): that he's in a new relationship so soon after Sherlock, causing an exasperated John (once again) to protest that he is ''not'' gay and Sherlock was ''not'' his boyfriend!
* ''Series/TheWarAtHome'':
** The series does this when Larry started a protest because the school wouldn't allow gay couples (like his best friend Kenny and Dylan) to a school dance. The TV broad-casted the words "Gay Teen Larry" despite that [[CampStraight he's not gay]].
** Also in an earlier episode, when Larry's parents see him kissing what they think is a boy, but is actually a very {{Tomboy}}ish girl.
** Larry's dad actually thought Larry was gay as early as in the {{Pilot}}. His mom, however, did not:
-->'''Vicky:''' Oh, and I told Larry he could stay over at Kenny's Friday night.
-->'''Dave:''' Again? At fifteen, you don't have sleep overs. Okay? Whatever you do with a bud you can finish by ten o' clock. I'm telling you, he's gay.
-->'''Vicky:''' You don't know that!
-->'''Dave:''' Vicky, when you don't know if someone's gay or not, they're always gay.
* The basic premise of Korean drama ''Series/PersonalTaste'', beginning unintentionally with Jeon Jin Ho and No Sang Joon's elevator scene, and continued as an excuse for Jin Ho to move in with Kae In.
* In the ''Series/MarriedWithChildren'' episode "Her Cups Runneth Over", Al and Steve go to a lingerie store to buy bras for Peggy:
-->'''Steve:''' ''(to the saleswoman)'' We're up from Chi-town. We're interested in the Fancy Figure 327. For my friend here.
-->'''Saleswoman:''' Size?
-->'''Al:''' Oh, gee, I don't know, uh... How 'bout this tall? ''(shows it with his hands)''
-->'''Saleswoman:''' Oh, I see. Don't be embarrassed. We often cater to people like you. Now, what size does your boyfriend like to see you in?
-->'''Steve:''' No, no, no oh, no, you don't, you don't understand. We're married! Uh, not too each other, to uh, to women.
-->'''Al:''' And if I was gay, I'd like to think I could better than him.
* ''Series/{{Community}}'':
** Abed spends forty-five minutes in a bar with a guy talking about ''Series/{{Farscape}}'', at which point the frustrated guy bluntly asks him if he wants to have gay sex with him, and he immediately refuses. In a twist, Abed admits he knew the guy was hitting on him, he just ''really'' wanted to talk about ''Series/{{Farscape}}''. Although Abed never told him he ''wasn't'' gay...
** ''Community'' does this a lot. There is a RunningGag that Pierce thinks both Jeff and Britta are gay. One episode had Britta make friends with a lesbian essentially just to brag that she had a lesbian friend and was therefore more tolerant and morally superior than anyone who did not. It turned out that the other girl was straight, thought ''Britta'' was a lesbian, and made friends with ''her'' for the exact same reason.
* On ''Series/TheGame2006'' when Tasha had a small spat over the cost of an office space with a Realtor. It is sure to assume that even the audience thought that the ''flamboyant'', well dressed, finger snapping, miniature dog carrying, Realtor was homosexual. But as it turns out:
--> '''Tasha:''' Sorry I had to bring the dog into this.
--> '''Realtor:''' This isn't my dog, it's my wife's.
--> (Tasha does a double take)
* ''Series/{{Bones}}'':
** Averted on an episode of ''Series/{{Bones}}''. Booth and Sweets both decide to propose to their respective girlfriends and go to buy their engagement rings together. [[YaoiFangirl Unfortunately]], the clerk at the jewelry store doesn't misunderstand their relationship.
** In another episode, the team investigates the death of a wedding planner. Everyone thinks her [[CampStraight executive assistant]] is gay until near the end of the episode.
* Played with in the first series of ''Series/{{Blackadder}}'', where Edmund is pretending to be gay to scare off his fianceé. Baldrick tells him to practice by pretending to make a pass at Percy, and leaves. While Baldrick is out Percy makes an annoying comment and Edmund attacks him. Baldrick comes back to find him sitting on top of Percy, and says, "Yes, that's the kind of thing!"
** Inverted (and played with) in Series 2, when Blackadder is about to kiss Bob (who is actually a girl called Kate). Baldrick comes in to find Kate on the ground and Blackadder on top of him, and reassures Kate, "Don't worry, Bob. He used to try and kill me too."
*** Technically Blackadder ''is'' mistaken for gay as everyone finds it very strange that he is spending all his time with his manservant, with Queenie remarking, "Do you think he'd spend more time with me if I was a boy?"
* In ''Series/StillStanding'' there's the oldest son, Brian, where his sexual orientation is often questioned by his own family. He twirls a baton, reads ''Vogue'' magazine (because he claims some of the models wear see-through clothing), and even joins the cheer leading squad (but only so he can meet girls).
* On ''Series/NewsRadio'', this occurred when Dave and Beth took Matthew to the ER for an injury. The attending nurse took one look at Dave acting concerned and said, "So you must be the boyfriend?"
* On ''Series/{{Crownies}}'', Tatum spent the first several episodes believing that Richard was gay; even going to so far as to tell her fiancee that he didn't need to be concerned about Richard moving in with them because he was gay. When she discovers the truth, she tells him it would be best if he was "straight at work, gay at home".
* ''Series/{{Being Human|UK}}'': In the pilot, a realtor assumes George and Mitchell are a couple. George is embarrassed, but Mitchell just runs with it. It's worth noting that in subsequent episodes Mitchell is pretty heavily implied to be [[BiTheWay bi]].
-->'''George:''' How could she assume that we were a couple?
-->'''Mitchell:''' I know! I am ''way'' out of your league.
* ''Series/BreakingIn'': Melanie's boyfriend misinterprets all the signs that Cam is interested in Melanie as signs that he's gay.
* ''Series/HappyEndings:'' Alex goes to a Halloween party dressed as Creator/MarilynMonroe and hits it off with a cute guy. Turns out he is a gay man who thought she was a transvestite, due to her TomboyishName and a seriously hoarse throat.
* The 1993 Australian mini-series ''Secrets'' opens with some trainee spies in an exercise where they have to go into a pub and get three facts about any person there. One of the trainees ends up thumping a gay man who thinks he's coming on to him -- needless to say he's regarded as too volatile for espionage.

* On an episode of ''Series/ArrestedDevelopment,'' George Micheal said trying out for the school play had [[BlatantLies nothing to do with impressing a girl]] in order to hide his [[KissingCousins incestuous crush]] on Maeby.

* On ''Series/HelloCheeky'', John was sometimes mistaken for gay, as he wasn't married. He wasn't too bothered by it -- possibly since Tim and Barry occassionally seemed to be ''genuinely'' gay in denial, ''despite'' being married.

-->'''Barry:''' ...a swan?
-->'''Tim:''' No, is he...''(puts hand on hip, makes limp-wristed gesture)''

-->'''Steve:''' "I'm sorry, you think I look old enough to be her father?"
-->'''Danny:''' "Th...That's the part you bumped on?"

-->'''Alex:''' He told you that?
-->'''Tony:''' No, I'm just assuming.

** When Kara tells Winslow Schott that she's Supergirl, he initially assumes that she's trying to tell him that she's gay.
** Leslie "Livewire" Willis accuses her of having a "Sapphic vibe", although that's more just a slur than an actual mistake.
** When Astra sees a framed photograph of Alex and Kara in Kara's apartment, she tells Alex that "I knew there was more to you and my niece." Alex has to explain that Kara is her adoptive sister.
* Frederick Bellacourt, the clueless male heir in ''Series/AnotherPeriod'', is being groomed to be the next senator from Rhode Island - until his lack of macho behavior gets him labeled as gay. By Sigmund Freud, no less. Who then catches Frederick ''and his sister Beatrice'' [[BrotherSisterIncest in bed together]]:
-->'''Dr. Freud:''' Frederick, look at you. You are cured. The Masculinity training must have done the trick. I officially declare you a non-homosexual.\\
'''Beatrice:''' Oh, Frederick, I'm so proud of you.\\
'''Frederick:''' You're not concerned at all with the fact that I'm having sex with my sister?\\
'''Dr. Freud:''' Seems perfectly natural to me. Carry on.
* ''Series/NipTuck'': When HeterosexualLifePartners Sean [=McNamara=] and Christian Troy are selecting chocolate for Christian's upcoming wedding, the chocolatier mistakes them for a gay couple because of how comfortable they are discussing their love lives with each other.

Oliver is outraged: if he ''were'' gay, he certainly wouldn't fancy Simon!
* Lester on ''Series/{{Chuck}}'' was mistaken for gay, although the person at least got the gender he is attracted to right, as he was mistaken for a gay ''woman''. It's probably a good thing that Lester didn't hear this, as [[CasanovaWannabe he'd probably just use it as an excuse to hit on lesbians]].
* One episode of ''Series/{{Donny}}'' has Donny Deutsch accidentally declaring that he wishes he was brave enough to come out, which everyone else assumes to be him admitting to being in the closet. HilarityEnsues.
* Ilana on ''Series/BroadCity'', though complicated by her apparent pansexuality. She becomes angry after discovering Abbi kissed another woman, claiming she was promised Abbi's first same-sex experience. In another episode this exchange occurs when Oliver, a young boy she babysits, paraphrases some of her statements about Abbi:
-->'''Oliver:''' We hung out with Abbi, Ilana's girlfriend, even though they can't be together right now. But they will be someday.
-->'''Oliver's mother:''' Ilana, I had no idea you were gay.
-->'''Ilana:''' We all...
-->'''Oliver's mother:''' Having a gay-bysitter will be wonderful for Oliver's CV to get into middle school.
* This apparently happened to Fozzie in ''Series/TheMuppets'' when he tried to get into online dating.

-->'''Cameron:''' You're not my type.
* ''Series/TheFamily'': Hank's mother asks if he's gay due to his lack of interest toward women. He's actually a pedophile, though he hates it.
* In the late-80's--early 90's, ''Series/SaturdayNightLive'' featured a character "Lyle, The Effeminate Heterosexual" who was frequently an example of this trope, much to his shock and confusion. To the point where even his own wife and mistress assumed this, despite dialogue that indicated he was an excellent lover.
* On ''Series/SiliconValley'', when Monica confronts Erlich after he outs her as a smoker:
-->'''Monica:''' Thanks for outing me.
-->'''Erlich:''' You're gay? That explains so much.
* ''Series/NewTricks'': The boys come to the conclusion that Sandra is a lesbian after trailing her to a mysterious assignation with another woman in "1984". Sandra finds this hilarious and soon sets them right: the woman she was seeing was not her girlfriend, but her shrink.
* ''Series/TheHandmaidsTale'': Fred finds out that June had a past with Moira, and arranges for them to meet in Jezebel's when he visits again, thinking they were lesbian lovers. June corrects this, though, and Fred then lets them have some time together anyway (he seems oddly okay with the idea they were lovers in the past, despite echoing the usual anti-gay stance of the regime by calling Moira "degenerate").

* ''Series/MontyPython'' plays with the term in "Biggles Dictates A Letter," taking the term as we interpret it commonly over what the term actually meant as originally defined. When the dialogue between Biggles and his secretary lead him to believe his friend Algy is a homosexual:
-->'''Algy:''' (''strong masculine voice'') What ho, everyone!\\
'''Biggles:''' Are you gay?\\
'''Algy:''' I should bally well say so, old fruit! (''Biggles shoots Algy dead'')

* A line in Music/WeirdAlYankovic's song "Couch Potato" (a spoof of Music/{{Eminem}}'s "Lose Yourself") has the line, "But I only watched ''Will & Grace'' one time, one day. Wish I hadn't, cause [=TiVo=] now thinks I'm gay!"
** A fake interview with [[http://www.youtube.com/watch?v=0QOya9-lwQk&feature=channel Eminem]] makes Slim Shady pretty weird...
* The song ''Secret'' by Music/TheVeronicas:
-->You could call me six times but still I won't pick up the phone\\
You could spend all your money on me but still I'll say no\\
You could write a million letters everyday confessing to me\\
That I am the girl of your dreams\\
But nobody ever asked me\\
[[AllLoveIsUnrequited I never looked at you that way]]\\
'Cause I always thought you were gay
* Music/BoBurnham's song "My Whole Family (Thinks I'm Gay)"
* The entire premise of the Music/StephenLynch song "If I were gay" [[http://www.youtube.com/watch?v=DgAYFVHwY_c (VERY NSFW)]]
-->But if I were gay\\
I would give you my heart!\\
And if I were gay\\
you'd be my work of art!\\
And if I were gay\\
we would swim in romance...\\
but I'm not gay - so get your hand out of my pants.
* Folk singer-songwriter Fred Small made a point of avoiding any references to gender in his lovesongs, so that listeners could interpret them as being about a person of any gender they liked. This, plus a number of overtly pro-gay rights songs, led to a lot of speculation among fans that Small was gay, and he studiously avoided confirming or denying it. He "came out" as straight in 1993, in response to the wave of homophobia over the issue of gays in the military, because he felt it was important that straight allies make themselves known. (His last album does contain one song, "Reverie's End," in which his lost love is definitely a woman because he recalls imagining she was pregnant.)
* Sloppy Seconds' song "I Don't Wanna Be A Homosexual" is all about this trope.

[[folder:Stand-Up Comedy]]
* Subverted in a bit featured in Creator/JohnMulaney's "New in Town," in which Mulaney confesses that while he is a straight man, he probably shouldn't be, and understand assumptions that he's gay.
* Happened to Tim Nutt.
--> I went to Gay Pride last year. [[{{Mondegreen}} I though they said beer]]. "Swing by the parade, there'll be thousands of beers", that's what I heard. It was fun! I was glad I went. Took me a while to figure out what the hell was going on, though. Got down there, full of enthusiasm, "We're here! We're beer! We're here! We're beer! We're... we're... we're what? All of ya? Wooow! You guys are gonna laugh! I heard the wrong word. What do you say we get together Saint Patrick's Day. I'd more comfortable with that. Or maybe I'll see you at your wedding."

* This is a fear of many in ''Theatre/BillyElliot'' due to Billy's love of ballet. Michael, Billy's less-flamboyant (in public, anyway) friend...seems to be Mistaken For Straight.
-->'''Billy:''' It says..."Billy Elliot is queer."
-->'''Father:''' ESQUIRE!
* Subverted in ''Theatre/AngelsInAmerica'': Joe walks in on Louis crying in the bathroom and in the ensuing conversation Louis assumes Joe is gay. He's completely right, but Joe just hasn't wrapped his mind around that yet.
* The musical ''Theatre/RockOfAges'' includes a character who is mistaken for gay through most of the show, which leads to the best line in the play: "I'm not gay! I'm just German!" The character's named Franz, and he's currently (as of November '09) played by Tom Lenk, who is gay.
* In ''Theatre/TwiceCharmed'', Prince Charming says that he loves the maiden at the ball, but the Grand Duke thinks he's referring to him.

[[folder:Video Games]]
* ''VideoGame/DeusExInvisibleWar'': If playing as a male Alex, the player can use this to their advantage when trying to break into the Minister of Culture's apartment. If the player convinces him he wants to come over to be a ''chamber boy'', he'll give access to the place, allowing the player to raid it.
* ''VideoGame/TwentyTwentySeven'': When Daniel first leaves the safe house in Paris, a woman sitting outside will begin hitting on him, then inquire about Xander (Daniel's work partner and platonic friend). She'll immediately assume there is something more going on, and will become disappointed.

* ''VideoGame/ShinSuperRobotWars'': [[OriginalGeneration Rai]] is thought to be gay by a good number of characters because his teammate Ryusei was going around telling them so. Rai responds by punching Ryusei in the face so hard that nobody questions his sexuality anymore. [[CharacterizationMarchesOn Thankfully Ryusei isn't like this anymore]].
* Mick in ''VideoGame/TheWorldEndsWithYou'' apparently has so little confidence that he assumes Neku gives Mick his patronage because he's gay for him.
* ''VideoGame/MakaiKingdom'' delivers us this particular little gem in a dialogue between Zetta and King Drake the Third:
-->'''Zetta:''' Aren't you the one who attacked me in my sleep?\\
'''Drake:''' ...Only because I wanted your ''junk''.\\
'''''PREGNANT PAUSE'''''\\
'''Zetta:''' ...You sick bastard... I didn't know you swung that way.\\
'''Drake:''' What the hell?!! No, no, no, no! I wanted your money, you-your valuables!
* Speaking of Nippon Ichi games, there's this little exchange in ''VideoGame/DisgaeaHourOfDarkness''
-->'''Laharl:''' ...What? What's the problem now?\\
'''Aramis:''' ...Thank you, Your Highness.\\
'''Laharl:''' H, Hmph...! Well, it ''is'' part of my job as the Overlord...And don't bother to thank me. If you want to show your gratitude, you can repay me with your body.\\
'''Etna:''' Hmmm... I never knew you were like ''that''...
* This is one of [[TheBigGuy Kanji's]] issues in ''VideoGame/{{Persona 4}}''. In fact, his shadow takes the form of a CampGay.
** It takes on a more MachoCamp feel for the BossFight form too.
** Though Kanji's sexuality itself is kind of a point of contention in the fandom. The fact that his semi-canon pairing is with a tomboy with gender dysphoria doesn't really clarity matters. WordOfGod is that this was done intentionally.
** For a brief moment Kanji makes this mistake about [[YamatoNadeshiko Yukiko]] when she tells him about her own experiences of having to confront her shadow.
-->'''Kanji:''' So like, that means you came out to everyone too?\\
'''Yukiko:''' Th-That's...Um...\\
'''Kanji:''' What was it like for Senpai--\\
'''Yukiko:''' *Slap*.
* Valygar in ''VideoGame/BaldursGateII'' is mistaken for gay by quite a number of characters. When he denies it, they delight in mocking him, which includes him being called a "fruit" by Cernd.
* Raidou gets this a ''lot'' in ''VideoGame/RaidouKuzunohaVsKingAbaddon'', partly because he spends a lot of time looking for men (specific ones, for detective-work-related reasons) in the neighborhood of Tokyo where the gay prostitutes hang out. Tae also thinks he and Narumi are a couple at one point (granted, so do [[YaoiFangirl many of the fans]]).
* In ''VideoGame/StreetFighterIV'', the fan favorite Turkish oil wrestler was originally thought to be SUPER gay by the fandom, until it was revealed that he has a wife and kids.
* In the PC-98 exclusive ''[[VideoGame/{{Touhou}} Story of Eastern Wonderland]]'', the samurai Meira introduces herself and her intentions to "take" Reimu (in a fight to gain her powers). Reimu mistakes this for a marriage proposal [[EngagingConversation and accepts]], much to Meira's confusion. By the time she figures it out and explains herself, [[HilarityEnsues Reimu's stopped listening altogether]].
* ''VideoGame/FireEmblemAwakening'':
** Lon'qu has [[DoesNotLikeWomen rampant gynophobia]] due to [[spoiler:a female childhood friend being killed when he was unable to help her.]] As a result, he cannot stand being within a certain range of the female members of the army, and [[GameplayAndStoryIntegration his quotes and reactions change when he's talking to one]]. In a DLC map, another party member, Vaike, asks him about it, and when Lon'qu refuses to talk, Vaike [[CrowningMomentOfFunny immediately assumes that Lon'qu is gay]], assuring him that there was nothing to be ashamed of. Naturally, he gets verbally thrashed.
** This is also present in the Female Avatar's conversations with Flavia, who wants to offer her the chance to be her adopted sister, but phrases it in such a way that suggests it's a proposal of marriage. Avatar tries to explain she's not into women, [[DiggingYourselfDeeper and Flavia talks about how gender doesn't matter to her in such a way that it sounds like she's bisexual]]. It is eventually cleared up, but much HilarityEnsues before then.
* Briefly in ''VideoGame/MetalGearSolid'', in the long cutscene when Snake and Otacon first meet. Snake is checking whether or not Otacon is suffering from FOX-DIE. Otacon just assumes Snake is coming onto him. Later in the scene, he interprets Snake's confusion over what he means by how Meryl, despite being dressed as a soldier, is 'still all woman' as Snake being "[[UnusualEuphemism dense]]", although this is a possible subversion because what Otacon ''actually'' means is that Meryl still has to use the ladies' bathroom.
* In ''VideoGame/RuneFactory4'', Frey walks in on Doug [[spoiler:practicing his proposal with Dylas in his reverse proposal event]] and wonders if they [[BelligerentSexualTension fight all the time to hide their feelings for one another]].
* ''VideoGame/GrandTheftAutoV'':
** The Triads mistake Michael and Trevor for a gay couple due to their being seen alone together during various parts of the story. When Franklin shows up, their begin to wonder if he's their ''other'' boyfriend or adopted son?
** After he starts hanging out with Michael, it's mentioned that some people back in the hood thought that Franklin had been whoring himself out as a rent-boy to rich white guys in Vinewood.
* ''Two'' characters from ''VideoGame/BarOasis'' gets this treatment. Vic suffers this treatment twice. First Desree though Vic was gay because he was "interested" in Creator/HarukiMurakami's work. Then Vicky accuses him of being gay. Vicky also accuses the Boss for being gay due to the "No dating customers" philosophy. One should note that Vicky runs a gossip rag that pegged them both as gay.
* In an optional scene in Chapter 9 of ''VideoGame/RakenzarnTales'', [[Manga/DetectiveSchoolQ Kyuu]] and [[Franchise/DotHack Kite]] happen to run into each other and decide to go get some lunch. As it would happen, some of the [[Manga/MahouSenseiNegima Negima]] girls are at another table in the same cafe, see them together and jump to this conclusion, thinking it was a RescueRomance deal. Eventually, one of the girls loses her patience and yells at the guys to start making out, much to their confusion.
* In ''VideoGame/FarCry4'' [[TheCaligula Pagan Min]] mentions that people often make this mistake about him, since he is very flamboyant and wears a [[RealMenWearPink bright pink paisley suit]] (described in-game as making him look like a "metrosexual pimp") but is by all indications straight, having only ever loved [[SingleTargetSexuality one woman]]. Apparently he chose the style to honor [[EvenBadMenLoveTheirMamas his British mother]] and annoy his [[TheTriadsAndTheTongs Triad crime lord]] father. He personally has no problems with homosexuality and apparently [[EqualOpportunityEvil accept them in his Royal Army]].
** There's some RealLife subtext to this: The reveal of Min's character design drew complaints online, as some commenters complained about Ubisoft using the old DepravedHomosexual villain cliché in 2014. Thus, Min's remarks about people assuming he's gay just because he wears a pink suit can be seen as a TakeThatCritics to the complainers.

[[folder:Visual Novels]]
* ''VisualNovel/LittleBusters'': At one point when Riki and Kyousuke are having one of their typical HoYay-filled scenes - Kyousuke reaches around Riki's collar to take off a piece of lint, leaving their faces very close - [[CovertPervert Mio]] comes across them. She, well, [[ShippingGoggles interprets the scene]] as any YaoiFangirl would. The conversation doesn't help - when she asks if she's interrupting, Kyousuke says that she somewhat is, and then asks her to join. At first she's very pleased by it all, and even thanks Riki at being able to see something so beautiful, but realises on her own that she misinterpreted the scene. All this time, neither Riki nor Kyousuke ever figures out what she was thinking.
* ''Franchise/AceAttorney'':
** In the second case of ''VisualNovel/PhoenixWrightAceAttorney'', you can either accuse Marvin Grossberg of [[spoiler: his [[BlackMail obvious connection]] with Redd White,]] or...
--->'''Phoenix:''' It's not something I can claim to understand... But you and Mr. White are lovers, aren't you!\\
'''Grossberg:''' W-w-what! My boy!\\
'''Phoenix:''' You sent that painting to him! As a sign! A sign of undying love!\\
'''Grossberg:''' M-m-my boy, please! You're letting your fancies run away with you! Where do you get these bizarre ideas?\\
'''Phoenix:''' I... I don't understand how you could...\\
'''Grossberg:''' That's because I'm not, we're not... Don't be ridiculous! Enough. I'll swallow my pride and tell you all.\\
'''Phoenix:''' (I knew it! They are lovers!)\\
'''Grossberg:''' N-no! We are NOT lovers!
** If you show Larry a picture of [[{{Bishonen}} Ron DeLite]] during the segment where he's scolding himself for being a womanizer, he'll assume that you're offering to hook the two of them up and will apologetically tell you that [[IncompatibleOrientation he can't switch orientations]].
** If you examine the detention center guard in ''VisualNovel/ApolloJusticeAceAttorney'', he'll eventually notice and wink at you. Curiously, this only happens if you're playing as [[CluelessChickMagnet Apollo]]; the guard just ignores you if you're playing as [[AndNowForSomeoneCompletelyDifferent Phoenix]].
** When Apollo encounters Klavier for the first time, he can't help but be stunned by [[UncannyFamilyResemblance how closely he resembles Kristoph]]. Klavier misinterprets his staring.
---> '''Klavier:''' I must say I'm used to being inspected by the ladies... But this is the first time I've felt this way with a man.
* Jumin from ''VisualNovel/MysticMessenger'' is speculated at several points to be gay because of his constant rejections of women.

* In an early episode of ''Machinima/RedVsBlue'', Church gets this from [[CloudCuckoolander Caboose]] after trying to explain that the Freelancer the Blues hired is actually [[SamusIsAGirl his girlfriend]] after her voice-changer fails. Caboose mistakenly still thinks Tex is a guy and that Church is gay, leading Church to respond with [[SarcasmMode "Yeah, that's right. I'm a gay robot".]]
* ''WebAnimation/BowsersKingdom'' follows this trope an odd number of times, because Kamek is constantly calling Hal (and sometimes Jeff) gay:
** Episode 2:
*** Jeff and Hal flashbacked the time they took flying lessons from Kamek. When it failed, Kamek said "What are you, gay?!"
*** Hal got close to a squished Jeff so he can mourn for him. Jeff got revived and thought Hal was gay. When Hal spoke later in the episode, Jeff said "Shut up, gay face!"
*** When Jeff was squished again and Hal was mourning for him again, Kamek passed say and said "See! I knew you were gay!"

*** When Jeff mentioned to Hal that Franchise/DonkeyKong kept asking him to eat bananas, Hal said, "And they say I'm the gay one."
** Episode 10:
*** During the scene of Hal explaining why there are no subtitles for the speakable characters from episodes 8 and on, someone was apparently fiddling with the subtitles. The subtitles eventually turned into "I secretly love Kamek." when Hal said "Sometimes I really, really hate this place." Kamek saw this and said "I knew you were gay!"
** The Movie:
*** Not as close to the trope itself, but when Jeff and Hal (disguised as Mario and Luigi, respectively) were making there way inside Peach's palace, the Toad there said hi to them (he mistook them for Mario and Luigi), and blushed when he said hi to Hal (Luigi), and said "Ya know, I had a great time last night." Hal then asked "Are you insinuating that I'm a gay?"
** Episode 666:
*** When Jeff was trying to tell Hal about the zombie invasion, Hal wouldn't listen until Jeff told him that the zombies called Hal gay.

[[folder:Web Comics]]
* This was an ongoing subplot in ''[[http://www.avalonhigh.com Avalon]]'', especially the first year. Early on, Joe tells Ceilidh that her new friend Phoebe is gay ([[spoiler:a rumor started by a bitter ex-boyfriend]]); the amount of time the two spend together leads to a rumor that ''Ceilidh'' is also a lesbian, which is compounded when her probing for a definite answer, [[CannotSpitItOut without being too direct]], makes ''Phoebe'' think so as well. The "lesbian" subplot is essentially forgotten after the story's halfway mark, [[spoiler:until the undrawn ending, in the synopsis of which Phoebe confesses her love for Ceilidh, who, in the next "scene," ambiguously mentions "new relationships"]].
* Subverted in ''WebComic/{{Shortpacked}}''. Robin believes that the reason that Ethan doesn't show any interest in her is because he's secretly gay. However, when she confronts him about this, it turns out that Ethan actually ''is'' gay, but just didn't realize it; unfortunately for Robin, she just helped him work it out.
* ''Webcomic/EerieCuties'': Nina jumps to the conclusion that her sister, Layla, is a lesbian [[http://www.eeriecuties.com/strips-ec/drive_the_boys_wild when she walks in on her]] giving Brooke [[PracticeKiss a kissing lesson.]] Then runs off before they can explain and tells [[IneffectualSympatheticVillain Cess and Laura]] about it, who stage a rally in front of the entire school [[http://www.eeriecuties.com/strips-ec/the_surprise to humiliate Layla.]] Eventually, even ''her mom'' gets wind of it, [[http://www.eeriecuties.com/strips-ec/boys much to Layla's chagrin.]]
%%* A RunningGag in ''Webcomic/SomethingPositive'' is Davan (and occasionally Peejee) being mistaken for gay.
* ''Webcomic/TwoKinds'' has Keith and Natani. It gets confusing because [[spoiler:Natani considers herself male but is in fact not.]]
** Natani [[spoiler: is actually two people sharing two bodies as part of a medical procedure to keep them alive, one male and one female.]] So whether it's really a 'mistake' or not is something the characters themselves aren't sure of because [[spoiler: no one has a word or customs for defining the gender of a binary being]], though they're usually offended anyway, on principle.
* ''Webcomic/LastRes0rt'' cranks it up a notch; sure, Addy and Jigsaw end up caught on camera, but [[spoiler: Jigsaw is a vampire and thus was ''feeding'' on Addy, not sleeping with her]], so Jigsaw ends up [[SureLetsGoWithThat having to play along...]]
* ''Webcomic/{{Building 12}}''-- Joe and Alex are mistaken for this. Note that this is a variation as they ''are'' lovers, but Alex is [[{{Bifauxnen}} actually a girl.]]
* A running gag in ''Webcomic/PennyAndAggie'' with Aggie has several people (and, at one point, her best friend) believe or play with the idea she is gay. Also done with Penny. [[spoiler: [[SubvertedTrope Turns out, Aggie is a lesbian, and Penny is bi]], [[IfItsYouItsOkay at least for Aggie.]]]]
* This, understandably, is the assumption of ''Webcomic/TheOrderOfTheStick'' when they notice what appears to be Elan and a male police officer snogging passionately. The audience knows that they are really [[EvilTwin Nale]] and a shapeshifted Sabine.
** [[ILoveTheDead Tsukiko]] thinks she is mistaken for bi due to misinterpreting the Monster In The Darkness's comments that she "does both" (actually referring to doing both Arcane and Divine magic).
-->'''Tsukiko:''' I didn't know the Crypt Thing was female!
** Earlier, on Elan and Nale's first meeting, Nale's comments on Elan's handsomeness (or rather, his ''own'' handsomeness) lead Elan to ask "Are--are you hitting on me? Because whatever you heard about [[NoodleIncident what happened at summer camp]]--"
* Jae-min from ''Webcomic/OrangeMarmalade'', due to his HeManWomanHater nature, was mistaken for gay by a large group of people and also his best friend (who was worried Jae-min had a crush on him). Si-Hoo's obsessive and highly suggestive nature isn't helping his case and seems pretty determined to "have him".
* ''Webcomic/ElGoonishShive'':
** Tedd gets this at times from the football players that are shown. The JerkJock gives him a hard time; the other toes a more Politically Correct line. Neither really help Tedd feel better. At least neither know of his [[GenderBender favourite hobby]]..
** In addition, George assumed that Justin and Elliot were a couple. This is not the case, though [[IncompatibleOrientation Justin certainly wishes it was.]]
** This trope is the natural assumption about the extremely effeminate Noah, on the part of readers and characters, resulting in mild surprise/awkwardness when he talks about his girlfriend.
--->'''Noah:''' "You are surprised that I have a girlfriend?"
--->'''Elliot:''' "''What? No, not at all!''"
--->'''Noah:''' "It is okay if you are."
--->'''Elliot:''' "''I ASSUMED NOTHING!''"
--->'''Noah:''' "Of course not."
*** Of course, Noah also freely admits that he can make straight men [[StupidSexyFlanders see rainbows]].
** After Elliot and Sarah's breakup, and the fact that they're still friends, is mentioned on Elliot's web show, rumors start to circulate to the effect of Elliot being gay. What these people don't know is that the very thing that sparked the breakup, on Elliot's side, was [[spoiler:his budding feelings for Susan.]] Interestingly, Elliot doesn't give a damn when he finds out, merely saying "Eh, let them think what they want".
** In the Magic tournament storyline, Tedd assumes his opponent Larry is gay, based on the reasonable grounds that Larry is blatantly hitting on him. Nope, Tedd's [[DudeLooksLikeALady just that girly]].
** Catalina thinks that Susan's misandry means she might be playing for the ladies' team, and asks her out. [[IncompatibleOrientation Susan's a little saddened to turn her down]].
* ''Webcomic/{{Bobwhite}}''. Marlene does a brief internship with Jen, a director who's a big deal in the independent film circuit. They're a great match on the set. [[http://www.bobwhitecomics.com/?webcomic_post=20110203 Then Jen gives Marlene a big kiss]], only to realizes seconds later that Marlene didn't like her ''that'' way. (The real {{irony}} is that Marlene took this internship in the first place to get ''away'' from relationship drama.)
* ''Webcomic/GunnerkriggCourt'''s Kat has been mistaken for gay by Paz, thanks to a conversation in which Kat extolled Paz's virtues. For the record, Kat has actually ''had'' a boyfriend, even if he did turn into a bird and Paz is getting over the shock of finding that her crush has a crush on [[https://en.wikipedia.org/wiki/Chang%27e ''Chang'e'']], of all people. In the next chapter she's wearing a flower in her hair, apparently in an attempt to seem more girly. And then [[spoiler: [[BiTheWay they decide to give a relationship a try]]]]
* Sydney in an early ''Webcomic/UnintentionallyPretentious''. While she acknowledges the act of leading Mia in public to be innocent, she believes people see two girls walking together arm in arm and [[http://www.unintentionallypretentious.com/index.asp?c=32 extrapolate to sexy results]], and suggests that she get a guide dog for ''her'' benefit.
* In ''Webcomic/GirlGenius'', Sanaa thinks that Othar [[http://www.girlgeniusonline.com/comic.php?date=20100324 may have other reasons for wanting to save Gil, like being his boyfriend.]]
* ''Webcomic/UmlautHouse'' had a bit of a RunningGag where Saundra, ironically one of the straightest characters, was mistaken for a lesbian by strangers. Though there was an AlternateUniverse where her counterpart was a lesbian (and attempted to seduce her).
* In ''Webcomic/LuminaryChildren'', Cameron mistakes Rex and Rick for boyfriends. However, after the amount of HoYay between them up to that point (which, by the way, is approximately five pages after their introduction), most people would.
* In ''Webcomic/SandraOnTheRocks'', teenage gamers [[http://www.sandraontherocks.com/strips-sotr/take_off_my_top Alex and Marie's post-workout exhaustion combined with their video game trash talk]] gives one online listener the impression that not only are the two of them getting it on ([[ChildhoodFriendRomance not that Marie would mind]]), but that Alex regularly has sex with guys as well.
* Yoon Sung from ''Webcomic/WelcomeToRoom305'' gets mistaken for gay when he gets offended over men making homophobic remarks. [[spoiler:His sister is lesbian and at the time he felt guilty for being so homophobic towards her in the past.]]
* ''Webcomic/StringTheory'': [[http://www.stringtheorycomic.com/comics/chaptertwo/page-fortyone/ Phineas]].
-->'''Phineas''': No, no, no. Don't. Be. Dense. I know you, Dr. Herville Albert Schtein.
-->'''Schtein''': Oh God. You've got a weird crush on me, don't you?

[[folder:Web Original]]
* This is a ''[[OverlyLongGag VERY]]'' [[BrickJoke long]] RunningGag of the WebVideo/ComedyShortsGamer.
* ''Franchise/{{Noob}}'' plays around with that trope due to having a cast including a YaoiFangirl and an EffeminateMisogynisticGuy who happens to be a ''very'' dedicated HeroWorshipper. Only the webseries gave a somewhat definitive answer to the situation, with the guy affirming that he's being a CelibateHero (and claiming to avoid relationships with ''women''), but the very same episode showed that [[spoiler:he and the "hero" in question are on a much more friendly basis than they used to be. Later, upon witnessing one of the consequences of that friendship, the girl's reaction was basically "I can't picture this happening unless these two slept together at some point."]]. The actual situation hence seems closer to TheNotLoveInterest.
** Its SpinOff ''Literature/{{Neogicia}}'' has a female protagonist who shares a room and is HeterosexualLifePartners with an openly lesbian woman that currently does not have a girlfriend and is the most vocal of the two concerning how close they are to each other. The perfect recipe for making people that don't know them personally misread the situation. The protagonist herself has very heterosexual crush... on the emperor of her faction, which gives her plenty of pre-existing competition.
* ''Podcast/RandomAssault'': Matt by his real-life friends.

[[folder:Western Animation]]
* ''WesternAnimation/TheSimpsons'':
** In "Homer's Phobia", Homer ended up overreacting to many small silly things Bart was doing (such as wearing a Hawaiian shirt, or putting on a ladies' wig and singing the ''Shoop Shoop'' song) and taking it to mean that contact with an openly gay shopkeeper (played by John Waters) was making Bart "turn gay". After several attempts to make Bart "man up", Homer gives up and says that he's okay with whatever Bart wants to be. When Lisa finally explains it to him, Bart's reaction is "He thinks I'm gay?!"
** Played for laughs in another episode, where in an attempt at copying Bart's 'El Barto', Homer (helping build homes for the homeless) paints 'El Homo' on a wall in big letters. Cue a man coming up to him and saying something along the lines of "I wish I had your courage!". Homer then realises what he's painted, and panicking, hastily begins to paint over it.
** The trope was often averted with Smithers in earlier seasons, during his conversations with Mr. Burns.
** Happens often with [[ThoseTwoGuys Lenny and Carl]].
** Homer once said he thought Sideshow Bob was "out loud and proud".
** In "Last Exit to Springfield", Homer mistakenly thinks that Mr. Burns' attempts at negotiating with him and offering a bribe are Burns coming onto him. He storms off, saying he doesn't go for these "[[StealthPun back-door shenanigans]]".
** Mr. Burns is also subject to this when he's trying to improve his image by going on a Creator/HowardStern knock-off radio show, coupled with a '''heavy''' dose of HaveAGayOldTime.
** In "Glorious Grandpa", Marge thinks Abe is gay after finding his old wrestling wig in his room, and starts trying to set him up on dates with men.
* ''WesternAnimation/SouthPark'':
** Butters is quite feminine and gentle, so even his mom thought he was gay and gambled on his sexuality with his dad. Butters' sexual orientation was also the entire point of "Cartman Sucks", where he got sent to a [[CureYourGays Pray Away the Gay]] camp [[InnocentInaccurate for being "bi-curious"]].
** One [[CrowningMomentOfFunny hilarious]] instance of this, is someone assuming HeterosexualLifePartners Terrance and Phillip are gay. That someone, is ''Phillip himself.''
--->'''Terrance:''' Wow, Scott really hates us Phillip.
--->'''Phillip:''' Yes, perhaps he's homophobic.
--->'''Terrance:''' ...But we're not gay, Phillip.
--->'''Phillip:''' We're not?!
** In "Tonsil Trouble", Cartman gets AIDS from a botched blood transfusion and then passes it on to Kyle intentionally. Throughout the episode, people repeatedly assume that Cartman and Kyle are gay lovers (see the page quote) when they find out that they both have AIDS. Earlier, the doctor who diagnoses Kyle asks him repeatedly if he's absolutely ''sure'' he hasn't been having unprotected anal sex.
** Happens again in ''Cartman Finds Love'' between Cartman and Kyle. To keep Kyle from going out with the new girl for a few [[InnocentBigot naïvely racist reasons]], Cartman spreads the rumor that he and Kyle are (or at least were) dating. Funny enough, everyone seems to believe it pretty easily.
** In "Tweek x Craig", the entire town believes the two are a couple after the new Asian students make {{Yaoi| Genre}} art featuring them. Tweek and Craig fail to get people to stop shipping them together and they decide to go along with it after seeing how happy their "relationship" makes everybody. Interestingly, this actually ends up developing into a ''real'' gay relationship, as cemented in "Put it Down" two seasons later, where Craig calls Tweek "babe" and "honey" even when there is nobody they know around and thus no need to hold up a charade.
* ''WesternAnimation/TheCritic'': Jay Sherman's boss thinks he's gay, and that Jay has a huge man-crush on him, despite Jay's repeated insistence that he's not gay. Then again, considering Jay's ex-wife compared his sex appeal to that of a dead mackerel, it probably wouldn't be that good anyway.
-->'''Jay:''' You don't think I'm gay, do you?\\
'''Doris:''' No man in his right mind would sleep with you.\\
'''Jay:''' [[InsultMisfire Thank you!]]
* ''WesternAnimation/KingOfTheHill'':
** Bill Dauterive spends an episode purposely being mistaken for gay much like one of the examples above, as the trendy salon he is hired by only employs women and gay men, thinking straight men simply don't have what it takes to be good hairstylists. He blows his cover when an extremely attractive female customer flirts heavily with him and says it's a shame he's gay. Of course, when he "comes out" to her (loud enough for the whole salon to hear), she immediately becomes disgusted with him (and herself, for letting a straight man style her hair).
** Dale thinks that John Redcorn is gay. The same John Redcorn that his wife has been sleeping with behind his back for over 10 years, and is [[ChocolateBaby very obviously]] the real father of his son. In fact, this actually started when Redcorn was about to confess to the affair out of guilt but was stopped from doing so by Hank.
--->'''Dale:''' ''[to Hank]'' I was gettin' a weird vibe in there. You think he's gay?
** And Peggy's hairdresser from "Good Bye Normal Jeans": everything about him from the way he acted and dressed just screamed CampGay, but as it turns out, to Peggy's and the viewers' surprise, he has a wife and child.
** In the episode "My Own Private Rodeo", Hank tries to help Dale mend fences with his estranged father [[CampGay Bug]], who is, in fact, a gay rodeo rider; when Hank shows up at the Rodeo, Bug jumps to conclusions:
--->'''Bug:''' ''(intrigued)'' Oh my god, Hank. Are you gay?\\
'''Hank:''' ''(shocked)'' What?! No! I sell ''propane''!
** Hank spent much of the early seasons worried about Bobby possibly being gay especially when he took up modeling, this fear was put to rest in "Naked Ambition" when Kahn informs him that he caught Bobby and Connie half naked together, after Kahn leaves Hank laughs and breathes a sigh of relief. Later in the episode after Khan has erected a giant fence between their houses, Hank lets Bobby borrow a ladder so he and Connie can kiss.
** In the "I'm With Cupid" episode there's a Valentine tradition of girls giving carnations to the boys they like. Bobby gets two, so he lends them to his best friend Joseph, since it'll make the latter seem more desirable to a crush he has. Course, when Joseph moves to return them, one of their classmates sees the act and assumes Joseph is confessing his attraction to Bobby. On the plus side, said classmate simply says the act took courage.
%%* This exchange in ''WesternAnimation/JusticeLeagueUnlimited'':
%%-->'''Shayera:''' Why don't you just go talk to her?
%%-->'''Flash:''' What, me? Talk to her? No way!
%%-->'''Shayera:''' Yeah, you'd probably be wasting your time anyway. I hear she's...you know...
%%-->'''Flash:''' *turns to see Fire in a rather provocative position as she's speaking to Ice. Cue wide eyes*
%%-->'''Shayera:''' [[DiscriminateAndSwitch Brazilian.]]
%%-->'''Flash:''' Ha, ha.
%%** More of a MythologyGag, actually. In the comics, Ice (well, the second-and-maybe-fourth superheroine named Ice) pretty much seduced Fire, and they became long-time girlfriends. The pair are also seen living together towards the end of the series, so they're either official HeterosexualLifePartners or it's an [[GettingCrapPastTheRadar incredibly subtle]] case of BiTheWay.
* Happens quite a few times in ''WesternAnimation/TheVentureBrothers'' There's the doctor mistaking Brock for Rusty's partner, the hicks calling Dr. Orpheus gay in the diner, Rusty accusing Dr. Orpheus of trying to seduce him...
** Pete White gets this the most, because of his eccentric style, his lucky [[PinkIsForSissies pink shirt]], and because he [[HeterosexualLifePartners rooms with Billy Whelan]]. In ''Every Which Way But Zeus'', he's called out by, of all people, [[CampGay Shoreleave]]. When Billy's mother is introduced, Billy even has to confess to Pete that he ''told'' her they were gay—it was just easier than trying to explain two straight men living together.
* ''WesternAnimation/{{Sixteen}}'':
** Jonesy and Wyatt were mistaken for a gay couple by two girls they were trying to hit on. Jonesy was not amused.
** Nikki makes a new friend in one episode and there is strong evidence that the girl has a crush on Nikki. Nikki tries to ask her if she is gay, awkwardly stumbling over her words in an effort to avoid offending her. The girl thinks Nikki is trying to ask her out, and declines because she already has a girlfriend.
* Ace and Gary, the members of ''The Ambiguously Gay Duo'' fight villains who are believe that both members of the duo are gay and scheme to out them as such. According to WordOfGod, these villains are only half right but its unknown which member of the duo is the mistaken one.
* In ''WesternAnimation/{{Archer}}'':
-->'''Woodhouse:''' This is Sterling Archer, my...\\
'''Stinky:''' None of my business. Consenting adults and all that.\\
'''Archer:''' Wha...HEY! No one is consenting to anything!\\
'''Stinky:''' None of my business.
* On ''WesternAnimation/FamilyGuy'', Peter tries to help a co-worker.
-->'''Peter''': Derek, how are you getting to the picnic?\\
'''Derek''': I don't know. I don't have a ride.\\
'''Peter''': Hey, John, you got a two-seater, don't you? \\
'''Peter''': Hey, Derek, maybe you go with John? \\
'''Derek''': For the last time, I'm not gay! \\
'''John''': Thanks anyway, Peter. \\
'''Peter''': We'll get him.
* ''WesternAnimation/AmericanDad'':
** In an episode, Terry has to [[FlyingUnderTheGaydar fly under the gaydar]] to keep his bigoted father from finding out he's gay; in the process of pretending, he claims [[TheBeard Francine is his girlfriend]] and Greg (his actual partner) and Stan are "the homos from across the street". Terry's dad goes right along with this despite Stan's absolute lack of performance (he sees Stan wolf-whistle an attractive woman and snarks "Yeah, whistle a showtune, you fairy!").
** There was also that time Stan created his own theatrical one-man show about UsefulNotes/AbrahamLincoln and his fictional bodyguard played by Stan. It's a hit because of all the gay subtext Stan doesn't seem to notice.
* ''WesternAnimation/ClerksTheAnimatedSeries'':
** The series reveals what few fans there are in-universe all think that Dante and Randal are a couple.
** Additionally, the third episode had Dante forced to "admit" he was gay in order to save the entire town of Leonardo from being destroyed.
* ''WesternAnimation/{{Daria}}'':
** [[DumbJock Kevin]] and [[TheGenericGuy Mack]] were briefly mistaken for a couple while attending a bridal expo together. They were actually there to see their respective girlfriends in a fashion show.
** PlayedForDrama in "Is It Fall Yet?," when [[CoolLoser Jane]] befriends [[DepravedBisexual Alison]]. Alison gets Jane drunk (note that Jane is too young to drink) and comes on to her, claiming that she [[{{Gaydar}} never hits on straight chicks]]. Jane briefly begins to question her own sexuality, but eventually realizes that Alison was trying to do just that to help seduce her.
** Briefly in "Lane Miserables" when Jake answers the front door assuming it's one of Quinn's dates and sees a woman at the door.
-->'''Jake:''' Wow, I really ''don't'' know my kids!
* ''WesternAnimation/{{Futurama}}'':
** This happens to Kif Kroker in "Amazon Women In The Mood" when he, Bender, Fry, and Zapp Brannigan are sentenced by the Femputer to death by "snu-snu". While Fry and Zapp switch moods ranging from glee to terror, Kif just shows absolute terror and when Zapp sees the terrified looks on Kif's face, Zapp says "what are you gay?" to Kif when its clear that Kif is in love for Amy but has been having trouble confessing his feelings for her throughout the episode due to anxiety.
* ''WesternAnimation/TimeSquad'': This happens to Buck Tuddrussel at least twice in the series. He has had a lot of blatant subtext with CampGay robot Larry 3000. The subtext is so thick that other characters think that theres something going on between them. Tudrussel and Larry have been mistaken for ancouple engaged to be married by Albert Einstein, who refers to Larry as "the missus" and then Dr. Sigmund Freud approached Tuddrussel and Larry's "relationship" like he would towards a married couple. Tuddrussel has shown attraction towards multiple women in the show though.
* ''WesternAnimation/TotalDrama'':
** ''Revenge of the Island'' has an odd variant: [[DumbJock Lightning]] constantly mistakes [[BrawnHilda Jo]] for a guy. Things get very awkward when, in a thinking-they're-about-to-die situation, she confesses that she's never kissed a guy.
--->'''Lightning:''' Hey man, it's cool. Lightning doesn't judge.
** Geoff and Brody are such close HeterosexualLifePartners during ''The Ridonculous Race'' that some of the other contestant think they're a couple.
* A ParentalBonus joke in ''WesternAnimation/TheLooneyTunesShow'' episode, "Jailbird and Jailbunny"; Bugs and Daffy escape from jail and Bugs wants to turn himself in, but the police officer he talks to doesn't recognize him since Daffy dyed his fur to disguise him. Bugs asks the cop if he's not an escaped convict, why is he chained to Daffy? The cop's response: "Your personal lives are your business."
* In one episode of ''WesternAnimation/MyGymPartnersAMonkey'' when Adam almost accidentally kisses Jake while fantasizing about kissing Kerry:
-->'''Jake:''' Don't get me wrong, Adam; I know I'm quite a looker, and I like you and all... (comically deeper voice) but not that way.
* On ''WesternAnimation/TheClevelandShow,'' Junior changes his style and starts going by "[[GenderBlenderName C.J.]]" in an attempt to be cooler. He winds up befriending a girl from another school and asking her out to her prom...only for it to come out that she's a lesbian, and thinks he's one too. HilarityEnsues.
* In ''WesternAnimation/MikeTysonMysteries'', Mike thinks Yung is a lesbian when he sees her watching the WNBA. It doesn't help her case when [[AmbiguouslyGay Marquess]] also enjoys watching the WNBA.
-->'''Mike''': Oh, my God! Are you a lesbian?\\
'''Yung''': No, I'm not a lesbian.\\
'''Mike''': You're a lesbian and you're afraid to come out to me.\\
''(Mike looks at the empty beer cans, cigarette butts, prescription medications and bottles, and a bong around the living room)''\\
'''Mike''': Is that why you [[MistakenForJunkie drinkin' and druggin']], because you have so much shame?\\
'''Yung''': This is all Pigeon's, not me.\\
'''Mike''': Yung, I will love you no matter who you choose to lay with.
* ''WesternAnimation/BobsBurgers'' has an episode where Bob's Thanksgiving turkey keeps mysterious being sabotaged by someone in the family, forcing him to keep going back to the butcher to buy a new one. This leads the butcher to believe that Bob keeps coming back to flirt with him, at first offering to set him up with a friend but he eventually gets worn down by Bob and offers to go on a date or sleep with him. Bob actually briefly considers his proposition before awkwardly leaving with his turkey.
-->'''Butcher''': Oh my God, we're doing this!\\
'''Bob''': No, we're not.\\
'''Butcher''': Hey, what do you wanna do? You wanna go to the beach?\\
'''Bob''': No. Maybe. Wait, I'm straight. I mean, I'm [[AmbiguouslyBi mostly straight]]. You should call Tony.\\
'''Butcher''': Let's grab a coffee. No, let's just have sex! Oh God, this feels so great!\\
'''Bob''': I should just-, sorry I gotta go cook this. Also, I'm married. But if I wasn't... Who am I kidding, you're out of my league! It would never work.\\
'''Butcher''': What are you talking about?!\\
'''Bob''': I really gotta go!\\
'''Butcher''': I'm gonna see you tomorrow!\\
'''Bob''': Probably not. ...I'll call you!
* ''WesternAnimation/GravityFalls'': [[TheMenInBlack Men in Black]] agents, Powers and Trigger in one episode disguise themselves as a married couple during their investigation of the supernatural incidents occurring at Gravity Falls. They eventually drop the act but they bickered LikeAnOldMarriedCouple when they got into an argument on where Trigger left Powers' phone. Tambry walks in on the agents and then immediately walks out while telling them that she is "not even gonna ask" after seeing the agents bickers in a closet combined with the fact that Trigger was wearing a dress at the time.
* ''WesternAnimation/TheAmazingWorldOfGumball'': In "The Uncle", Ocho informs Gumball that his uncle is [[Franchise/SuperMarioBros Mario]]. Gumball declares "MARRY ME!" as Teri and Masami walk by, and Teri casually remarks "Called it". Masami tells Teri that [[SideBet she owes her $20]].
* The ''WesternAnimation/FredsHead'' episode "Fred TV" revolves around a reality show editing Fred's life to make it sound like he's hiding the fact he's gay. They promise to fix their mistake in the next episode...only to not only make the implications worse, but imply his parents are homophobic and have thrown him out on the streets.

[[folder:Real Life]]
* Voice actors Jeff Nimoy and Creator/QuintonFlynn unknowingly walked right into a yaoi movie together, which led to some speculations. However, they turned the accusations to their advantage and made a hilarious song out of it.
* In the seventies a rumor started as a joke caught hold, that Jim Nabors and Rock Hudson were going to get married. Both were gay, but there is no evidence that the two were ever in a romantic relationship.
* Plenty of actors known for playing flamboyant and/or villainous roles get this. Creator/MichaelSheen, Creator/ClaudeRains, Creator/DavidTennant, Creator/TomHiddleston... wait, the Britishness may be playing into this. Of non-Brits, Creator/JohnLeguizamo is frequently mistaken for gay. Creator/ConradVeidt [[NoBisexuals also gets this]], especially for ''Film/{{Casablanca}}''.
* {{Inverted|Trope}} in [[http://notalwaysright.com/definitely-not-right/999 at least one]] Website/NotAlwaysRight story. (With a bit of YouFailLogicForever to sweeten the deal.)
* Creator/PatrickStewart [[http://www.huffingtonpost.com/2014/02/19/patrick-stewart-outed-gay_n_4814994.html?ir=Gay+Voices had fun]] with the UK Guardian over this.
* Creator/GinaGershon played a bisexual character in ''Film/{{Showgirls}}'' and a lesbian in ''Film/{{Bound|1996}}'', and was apparently so convincing in her portrayals that she often gets hit on by women. She laughed it off in an interview, stating, "I kinda wish I could be a lesbian. So many girls come up to me all the time, I keep thinking, 'God, I should be a lesbian.' But unfortunately, I'm straight."
* In 2005, New York Mets catcher Mike Piazza held a press conference to declare his heterosexuality.
-->"[[Music/BelleAndSebastian Piazza, New York catcher, are you straight or are you gay?]]"
* Music/KTTunstall was mistaken for gay after her Eye To The Telescope album; many of the songs are ambiguous in this regard, and the cover art depicts her wearing a pair of rainbow suspenders.[[note]] "suspenders" here is American English for ''"braces"'', not "lingerie". Here she's actually in a man's shirt with braces, not the sort of suspenders a woman wears below the waist.[[/note]] Despite her statements to the contrary, [[MisaimedFandom many people think she's just in the closet.]]
** This perception of KT wasn't helped when she posed for a photoset with fellow singer Music/JossStone. Somehow Joss appeared ultra-feminine; Tunstall somewhat butch and mannish in mens'-style clothing. ''Possibly'' completely accidentally, [[https://sites.create-cdn.net/siteimages/5/5/8/55872/73/4/4/734414/278x368.jpg?1 the result]] looked like a [[ButchLesbian butch]]-[[LipstickLesbian femme]] partnership and fuelled rumours that both heterosexual singers were in a relationship - with each other.

* Around the time that Music/MelanieC, formerly of the Music/SpiceGirls, put her first solo album out, her stylists started putting her in some very soft-butch clothing for record art and press photoshoots, and even threw in some rather LesYay-loaded poses with female models. This naturally led to an awful lot of prurient tabloid speculation, which made a definite contribution to her unhappy mental state at the time.
* Former astronaut Michael Collins references this trope in his memoir ''Carrying The Fire'' when he describes how NASA started having simultaneous sleep periods for astronauts after Gemini 5; he says they had to be careful about the terminology because someone might misunderstand if they heard that a crew was "sleeping together."
* Musician Billy Squier's 1984 video for "Rock Me Tonite", directed by Kenny Ortega, featured him waking up from a bed with satiny pastel sheets and dancing effeminately around the room in a pink tank top (not quite the concept he had told Ortega he wanted to do). While the song was his most successful single ever, it was also his ''last'' hit single. Everyone thought he was gay, he could no longer sell out concerts, and the video is widely considered one of the worst ever since it ruined his career.
* Because of his overall looks and flamboyant personality, singer Mika was thought to be so. He later put the rumors to rest stating he's not straight, but then again he's not gay nor bisexual either (His declarations seem to place him somewhere among the lines of either polysexual or pansexual with the typical "no labels" argument). Later on, in August 2012, [[SubvertedTrope he came out as gay]].
* Seattle actor Jeremy Adams, who played a CampGay character in Mark Siano's cabaret show ''Modern Luv'', is heterosexual in the real world.
* [[Series/SesameStreet Bert and Ernie]]. On the one hand, WordOfGod may never have been ignored so much. On the other hand, all those TalkingInBed sketches only hurt their case. The Sesame Workshop's official line has for years been "They are not gay, they are not straight, they are puppets. They don't exist below the waist."
* Being an unmarried politician over the age of thirty usually leads to automatic gay rumors. US Senator Lindsey Graham (R-SC) is a commonly cited example, one of the few bachelors to pursue the presidency, and has frequently denied being gay. A friend and fellow Air Force officer was interviewed about this and stated Graham is "Nothing but heterosexual. There are stories that I cannot share to prove it but he is."
* Jonathan Davis, lead singer of the rock band {{Music/Korn}} had this problem early in the band's career, because of his flamboyant way of dressing during concerts, including wearing dresses. The band even had fun with this belief by making a [[https://www.youtube.com/watch?v=4OV-3Tgr3lc troll conspiracy video]]. However, Johnathan is married with children, and he had a reputation with female groupies beforehand. Clearly, this has been a problem for him going as far back as highschool, if the song "Fagat" is any indication. "I'm just a pretty boy. I'm not supposed to fuck a girl."
* Glenn Erickson, author of the DVD Savant film column, once [[http://www.dvdtalk.com/dvdsavant/s665hour.html shared an anecdote]] that while attending UCLA, he started receiving mail praising his stand on gay rights. Turns out another Glenn Erickson, a member of the Gay Student Union, had written such an article for ''The Daily Bruin''. Erickson considered writing a clarification, but decided he'd rather be mistaken for gay than mistaken for a homophobe.
* Music/WeirdAlYankovic got hit with this in the late 90's. He recounted that some of his mother's friends told her "Well, he's almost forty, and he's not married, and he lives in Hollywood. You ''know'' what that means."
* During the 2015 Academy Awards, Graham Moore, the winner of Best Adapted Screenplay for ''Film/TheImitationGame'', stated in his speech, "When I was sixteen years old, I tried to kill myself because I felt weird and I felt different and I felt like I did not belong." Given the film he'd written was about a closeted gay man who was driven to suicide by his orientation, many news outlets interpreted it as him coming out as gay. He later clarified that he is straight.
* Music/FranzFerdinand have spent their whole career having to point out that none of them are actually gay or bisexual, due to the very blunt and convincing male-homoerotic lyrics of "Michael" on their first album (they now claim that it was meant to be a tribute to Music/TheSmiths' more homoerotic material).
* During Operation Julie, a drug investigation by UK police in TheSeventies, a group of undercover officers on surveillance risked attracting hostile local attention when they were assumed to be members of a 'gay cult'. So several female officers where brought in, including one Sgt Julie Taylor whose name was eventually given to the operation.
