-> '''Dean:''' Is your name Pumpkin?
-> '''Triana:''' No, it's Triana. Doesn't your dad have a nickname for you?
-> '''Dean:''' Well, I've heard him call me 'Dave' or 'Don' a few times, but I don't think they're nicknames...
-->-- '''WesternAnimation/TheVentureBros''', "Eeney, Meeney, Miney... Magic!"

Alice is TheDitz, TheFool, a {{Cloudcuckoolander}}... the point is, she's an idiot. And since she's an idiot, she can't remember Bob's name, even though she's known him for ages. She can try, but it's unlikely that she'll ever hit upon the right name - [[YouCalledMeXItMustBeSerious unless things have just gotten real.]] Maybe she actually ''likes'' him and just has an odd way of showing it.

Of course, she may be a ''normal'' person, but even normal people get mixed up with names sometimes. Or she's just a jerk, and doesn't really care about Bob or his name. The outcome is the same - she can't pin the name down. This may be a RunningGag.

Better yet, maybe Bob is an [[LawOfAlienNames alien]], SuperHero, or an otherworldly creature in general, with a strange and/or [[OverlyLongName long]] name - how ''could'' she know it?

MaliciousMisnaming is a SisterTrope in which using the wrong name on purpose is a bullying tactic.

If the misnaming is a one-off incident in an emotional moment, it's WrongNameOutburst. If TheFool genuinely'' thinks'' Person B is someone else, it's ThoroughlyMistakenIdentity.

[[folder:Advertising]]
* In a [=FedEx=] commercial, a guy walks into a [=FedEx=]/Kinko's and sets down a package that he says needs to be shipped to Pahonicks. The rep claims they can ship anything anywhere, but he's never heard of Pahonicks. The customer gets exasperated and says it's the largest city in Arizona, to which another customer says, "You mean ''Phoenix''?" Cue awkward laughter from stupid guy, as everyone looks on in pity.
[[/folder]]

[[folder:Anime & manga]]
* In ''LightNovel/{{Bakemonogatari}}'', Hachikuji has a RunningGag of always mispronouncing Araragi's name in increasingly inventive ways, then claiming she "stuttered". It's implied she does this on purpose to tease him, rather than not remembering his name.
* ''Manga/{{Bleach}}'':
** Ichigo does this a lot according to Tatsuki, though not too frequently onscreen -- not only does he get names wrong, but he misread Uryu's name as a GIRL. He also manages to totally forget about a classmate who's been bugging him for years to join his club.
** Ichigo, upon meeting Yasutora Sado, misreads his name card, and keeps calling him "Chad" despite being corrected. The nickname eventually sticks, and in the dub and English manga (in which the classmates [[FirstNameBasis typically use first names]]), his classmates, teachers and Ichigo's other friends call him "Chad", when in the original, they had called him "Sado" -- only his grandfather calls him Yasutora.
** Due to the difficulty of pronouncing his name and her being a {{cloudcuckoolander}}, Orihime always calls Shishigawara "Sushigawara".
** Ichigo, after meeting Kurumadani Zennosuke, ends up often calling him "Imoyama". He gets quite annoyed, saying "If you don't know, just say so! Don't try to guess people's names!!"
* In ''LightNovel/ACertainMagicalIndex'' and ''Manga/ACertainScientificRailgun'', Touma Kamijou has a lot of trouble remembering Mikoto Misaka's name, so he almost always calls her Biri-Biri (Bug-Zapper in the English dub).
** Mikoto is deeply offended about how [[HypocriticalHumor "that guy"]] never uses her actual name, especially when [[spoiler: [[AmnesiacHero he forgets about her entirely]].]]
* In ''Manga/{{Club 9}}'': Haruo Hattori has such a thick country accent that when she introduces herself to Tokyo club hostesses, they immediately start calling her "Hello-chan".
* In the episode of ''Anime/CowboyBebop'' where the crew finds Ed's father, he has an assistant named [=MacIntyre=]. He never gets it right, always forgetting and at times calling him [=MacIntosh=] or something else beginning with "Mac". At least he's ''aware'' of the problem, at one point referring to his assistant as "[=MacInwhatever=]" when he was in a particular hurry and didn't have time to even ''attempt'' to get it right. (The assistant, naturally, yells a correction even as they hurry off.)
* In ''LightNovel/DateALive'', Reine always calls Shido "Shin". He doesn't bother to correct her.
* Because of some initial confusion, all of the Deimon Devil Bats in ''Manga/{{Eyeshield 21}}'' think Raimon Taro's name is "Monta." Sena misread the kanji for his name as "Kaminari Montarou"; Hiruma later uses this mistake to his advantage by claiming it's a nickname derived from football legend Joe Montana (and lies to Monta by saying he played the same position).
* In ''Manga/{{Gintama}}'', Katsura is constantly referred to as Zura (Which can mean "wig") by Gintoki and others, which almost always prompts him to say [[{{Catchphrase}} "It's not Zura, it's Katsura"]]. He's so used to being called by the name he'll sometimes say the phrase even if those in the vicinity aren't actually talking about him.
* ''Manga/GreatTeacherOnizuka'':
** Onizuka frequently calls Principal Uchiyamada "Xavier", after monk Fransisco Xavier, because of Uchiyamada's bald head. He doesn't do it on purpose at all, he seems to just associate the two in his mind for some reason.
** He also can't seem to remember Teshigawara's name at all. His attempts to recall it don't even come close. Just to give an example of how bad it gets, he once refers to him as "''Toxic Socks Warrior''", without any sign that he doesn't think it's his actual name.
* ''{{Anime/Hamtaro}}'': Jingle never seems to be able to remember Hamtaro's name. This leads to problems.
* Assistant chief security maid Yashima Sanae in ''Anime/HanaukyoMaidTai La Vérité''. In Japan, "Sanae" is normally a first name, so people often call her Sanae instead of Yashima even though they've known her for a long time. She [[InsistentTerminology always corrects them when they do so]], telling them that Yashima is her first name and Sanae is her last name.
* In ''LightNovel/IsThisAZombie'', Orito always calls Yuki Yoshida "Tomonori" because the kanji for her name also translate to Tomonori. He continues to do it even after she corrects him. A few other characters pick up the habit from hearing Orito do it.
* In the manga adaptation for ''Manga/KingdomHeartsII'', Donald and Goofy are referred to as Ronald and Zoofy by [[VideoGame/FinalFantasyVII Yuffie]].
* PlayedForLaughs in a ''Anime/LupinIIIRedJacket'' ChristmasEpisode, with the police chief constantly getting Inspector Zenigata's name wrong: "Inspector Pennsylvania", "Inspector Epiglottis"...
* ''Franchise/LyricalNanoha''
** Vita in ''Anime/MagicalGirlLyricalNanohaAs'' always screwed up Nanoha's name before they became allies. "Nantoka" actually means "something" and is used when someone refers to something that they do not know the name of. Also a bit of a pun, since the ''nano'' in her actual name is basically something you stick at the end of a sentence when you're not sure (which was the main aspect of the first season's IdiosyncraticEpisodeNaming).
-->'''Vita:''' Takamachi Nantoka!\\
'''Nanoha:''' It's Nanoha! NA! NO! HA!
** ''Manga/MagicalGirlLyricalNanohaInnocent'' gives us Levi Russell, a DumbMuscle who is just as bad with names in this AlternateUniverse as [[VideoGame/MagicalGirlLyricalNanohaAsPortable her original version was]], constantly mispronouncing Nanoha as "Nanyoha" and Fate as "Hate" despite both's attempts to set her straight.
* Because Luffy of ''Manga/OnePiece'' is a complete airhead, he always calls Boa Hancock "Hammock". He eventually starts to call her by her correct name, which she, due to being crazily in love with him, interprets as a proposal for marriage.
* ''Anime/{{Pokemon}}'': This happens to Butch a lot in both the English and Japanese versions of the anime. He's been called Botch, Biff, Hutch, Bob, Butcher, and many others. In the original Japanese, his name is Kosaburo, but he always gets called Kosanji. Seems to happen so often that he immediately replies "It's Butch!" when spoken to. In an episode of the spinoff ''Pokémon Chronicles'', Butch is actually called the correct name for a change, and he replies with "It's Bu-Oh, wait, that's what you said!" Another time, he called himself by the wrong name when attempting to correct someone when they got it right.
** Also a RunningGag with Stephan in ''Best Wishes''. It would get pronounced as "Steven" or "STEPH-an" and he was quick to correct it to "Steph-AN".
* Main character Madoka in ''Anime/RinneNoLagrange'' cannot for the life of her get Villagullio's name right and he eventually gave up on trying to get her to say it right. Eventually, so does Makoka and just calls him Guivi-nii, though she almost gets it when she tries again in the second season.
* Quite a few of the dolls from the ''Anime/RozenMaiden'' anime have trouble remembering fellow doll Kanaria's name.
* ''Anime/{{S-CRY-ed}}'': Straight Cougar kept getting Mimori's name wrong because he honestly can't remember her name because he's always in a rush.
* ''Anime/SailorMoon'': [[TheDitz Usagi]] does this in a "Sailor Stars" episode with the VictimOfTheWeek, called Garayan, calling him ''Garapan'', which means ''colourful men's underwear'' in Japanese. She just is that much of an airhead.
* In ''{{Manga/Saki}}'', Koromo tends to call Nodoka "Nonoka".
* In ''Manga/SakuraTrick'' Mitsuki can remember that Yuzu's name is [[http://en.wikipedia.org/wiki/Yuzu a citrus fruit]], but not which one.
* ''Anime/SDGundamForce'': Nobody ever gets Bakunetsumaru's name right the first time around. Because it's difficult for people not native to Ark to remember it, they usually call him 'Baku'.
* ''Manga/{{Toriko}}'': Zonge, a wannabe gourmet hunter, is frequently mislabeled as Zombie or a varient by almost everyone except his two sidekicks- even the [[UpToEleven captions]] get it wrong.
* Count Alses of ''LightNovel/{{Tytania}}'' always misremembers Fan Hyulick's name as "Fan Hyulen". He is corrected on a regular basis, but this only serves to irritate him.
* Dita from ''Anime/{{Vandread}}'' is the {{Cloudcuckoolander}} version. Despite the fact that she's romantically interested in the male lead, she can't seem to remember his name and calls him "Uchuujin-[[{{Honorifics}} san]]" ("Mr. Alien") instead.
* In ''Manga/{{Working}}'', Popura is such an airhead she cannot call her co-worker Souta Takanashi properly by his name, instead calling him "Katanashi", much to his frustration. Inami got confused with that until she found out that he only lets Popura call him that. Later, Popura meets three of his sisters at their home:
-->'''Popura:''' You are all Katanashi-kun's family members!?
-->'''Kazue, Kozue and Nazuna:''' It's Ta-ka-na-shi.
* ''[[BakusouKyoudaiLetsAndGo Bakusou Kyoudai! Lets and Go!! MAX]]'' involves a RunningGag where the IdiotHero Gouki always misnames [[TheRival Marina]] "Mariko". [[{{Tsundere}} She then never fails to try to correct him.]]
--> ''Marina'': My name is Marina! [[PunctuatedForEmphasis Ma-ri-na!]]
--> ''Gouki'': I got that already, Mariko!
[[/folder]]

[[folder:Comic books]]
* In ''Franchise/{{Tintin}}'', Bianca Castafiore just can't seem to get Captain Haddock's (or his butler, Nestor's) name quite right. The Captain gets his own back at one point. But what's funny is that she ''never gets it wrong the same way twice.''
* Rung of ''ComicBook/TransformersMoreThanMeetsTheEye'' is never correctly addressed by name when he is conscious or present. The other characters will either forget his name, mispronounce his name, or simply identify him based on his profession. However, characters do not seem to have this problem at all in prose stories or when he is not present.
* [[Comicbook/{{Bone}} "Roque Ja. ROGUE JA. You're not rolling the R."]]

[[folder:Fan works]]
* in ''Fanfic/AGameComesToEquestria'', this is [[spoiler: Hermos']] problem with his first appearance in the story, having his name mislabeled as "Hymie" [[spoiler: when he entered the [[Recap/TheLastRoundup rodeo]]]]. It isn't until the end of the whole event (and the events that followed) that everypony else gets to know his ''actual'' name.
* Examples from Fanfic/{{the Calvinverse}}:
** Played with in ''Fanfic/RetroChill'': it first appears that Evil Calvin calls Susie "Marcie", but he then reveals he was actually talking to ''Moe''. He then calls him "Mack" and "Ginger".
** From ''Fanfic/CalvinAndHobbesTheSeries'':
*** In a {{Crossover}} with ''Franchise/{{Batman}}'', Calvin calls Alfred "Horus". Whether or not's it's intentional or not is unclear.
*** Brainstorm mistakes Socrates for "Caesar", the only thing he remembers being that "[it] was Roman".
*** When defending Jack Freewater, Calvin keeps forgetting his name until the end.
* In ''FanFic/GensokyosHeart,'' Cirno can't pronounce Patchouli's name right.
---> '''Cirno''': Not now, Path... Pac... Pactouli!
* In ''[[http://www.fanfiction.net/s/8045114/42/A-Marauder-s-Plan A Marauder's Plan]]'', Sirius was having a hard time remembering the name of Fudge's assistant after some inadvertent Dementor exposure. He successively thought of the man as Marty, Monty, Murphy and Murray.
* ''WebAnimation/TurnaboutStorm'':
** [[Franchise/AceAttorney Phoenix]] unintentionally misnames [[WesternAnimation/MyLittlePonyFriendshipIsMagic Fluttershy]] as Butshersty, Flutterscotch, and Firefly at 3 different times. The latter two just so happen to be names of ponies [[MythologyGag of previous generations of]] ''Franchise/MyLittlePony''.
** [[NiceGirl Lenora]] keeps referring to Twilight Sparkle as "Twilight Sparkler" for some reason.
* It's mentioned early on in ''Fanfic/TheNewRetcons'' that John's fellow dentist Everett had to take out a full page ad in the local paper to tell him his name was not "Elliot".
* In fan fiction of ''Literature/TheLordOfTheRings'':
** ''FanFic/TheAwkwardAdventuresOfMeghanWhimblesby'' include her not telling that she is from another world. So Meghan pretends to be from "Ravendill", her wrong name for Rivendell.
** In ''FanFic/GroundhogGDIME'', Charlize from England wants to visit the "Bruinduin", a river in Middle-earth. She is misnaming the Bruinen or the Anduin. Charlize seems to get her own wish and find herself in the Bruinduin, "a small, unimportant river in some obscure part of Middle Earth".
** ''FanFic/{{Lothiriel}}'' by [=JunoMagic=] is about a woman from Germany. Many other Germans call her "Losíriel" because they can't say the English "th" sound.
** ''FanFic/NotAsPlanned'' has a fan who inserts herself into Middle-earth. This girl misnames almost everything because she is too stupid to know the correct names. "Like, it's not ''my'' fault you can't use English names right." She says "Riverdale", "Bramir", "Gamly", when the correct names are Rivendell, Boromir, Gimli.
* In the ''FanFic/TheTrainerFromAFarAwayLand'', [[RunningGag Satoshi can not pronounce N's name right,]] although it's due to the fact Kantonese has the same language limitations as Japanese, meaning he [[JustifiedTrope can't make the "N" sound.]] It happens so often that N gives up trying to correct Satoshi. Satoshi would pronounce N's name as Een-neh, Een-ne, Ennu or Enne.
[[/folder]]

[[folder:Film - Animated]]
* In ''FindingNemo'', the absent-minded Dory can never remember the name of Marlin's eponymous son, calling him at various points Chico, Harpo, Elmo, and Fabio. She eventually gets it right and recognizes him as Nemo near the end of the movie, much to her own delight.
* ''Disney/{{Frozen}}'' has a misunderstanding where Olaf the snowman believes that Kristoff is named Sven, the same as the reindeer. He proceeds to call Kristoff "Sven" for most of the film. Also, Anna calls Kristoff "Christopher" the first time and is corrected.
* In ''TheGreatMouseDetective'' Basil always gets Olivia Flaversham's last name wrong despite her (and later, the other characters) corrections. At the climax, he addresses her father by the proper name, so when he later messes up again when saying goodbye to Olivia, you know he's just being affectionate.
* Reggie Belafonte from ''SurfsUp'' does this; literally a second after being told our hero's name. Cody Maverick becomes Cody Mavencourt. Semi-justified, as the guy(?) cares pretty much zero about the clients he manages.
* In ''WesternAnimation/FlushedAway'', when Toad's mooks capture Roddy along with Rita, he claims to be just an innocent bystander. They misunderstand this as his name being Millicent Bystander, and refer to him as such for the rest of the film.
* ''Disney/{{Aladdin}}'': While Al is pretending to be Prince Ali Ababwa, Jafar keeps calling him Prince Abubu.
[[/folder]]

[[folder:Film - Live-Action]]

* A RunningGag of ''Film/BlazingSaddles'' has villain Hedley Lamarr being called "Hedy". Creator/HedyLamarr even sued the studio afterwards.
* In ''Film/TheBucketList'', Jack Nicholson's character, Edward Cole, has a habit of calling his subordinates whatever name(s) he prefers; the way he acts, you'd ''think'' it was accidental if it weren't shown clearly that he ''does'' know their real name (making this a subversion). It's not MaliciousMisnaming because it's not a variation of their real name or meant as an insulting or bullying tactic. He basically acts as if their real name is immaterial.
-->'''Ed:''' Do you know what a philistine is, Joe?\\
'''Richard:''' Sir, it's Richard.\\
'''Ed:''' That's right, Phil. Now, give 'em the spiel.
** Later we find out he's done the same thing to his personal valet, Tommy (though [[DeadpanSnarker Tommy]] might just be messing with Carter):
--->'''Carter:''' Can I ask: Is it Tommy, or Thomas?\\
'''Tommy:''' Actually, it's Matthew, but he finds that too Biblical.
* A RunningGag of ''Film/DOADeadOrAlive'' is people calling Weatherby "Wallaby" or something like that. At the end, his love interest Helena calls him by his name, which leads to him angrily trying to correct her before he realizes she got it right.
* A character in ''Film/TheDukesOfHazzard'' movie misremembers Enos' name as "Anus". WesternAnimation/FamilyGuy did the same joke, and they're probably not the only ones.
* The hero in ''Film/{{Idiocracy}}'' says "I'm not sure if..." to a machine, which proceeds to assume his name is literally 'Not Sure' and [[ScannableMan tattoo this name on his arm]]. Everyone calls him 'Not Sure' for the rest of the movie.
* In ''Film/JohnCarter'', John introduces himself as "Captain John Carter of the Army of Virginia" to the Tharks. The Tharks assume his name is Virginia and never catch on to their mistake. John gets annoyed at first but rolls with it.
* In ''Film/ShanghaiNoon'', Creator/JackieChan's character introduces himself as Chon Wang, but Roy and the other Wild West characters mistake this for Creator/JohnWayne...and comment it's a stupid sounding name.
* In ''Film/{{Skyfall}}'', James Bond introduces M to Kincade, and Kincade thinks her name is "Emma". She shows a slight hint of annoyance before she decides to just let him think that.
* In ''Film/TheDouble'', Simon's boss keeps calling him “Stanley”, despite the fact that Simon has worked for him for seven years.
* In ''Film/LivingInOblivion'', Nicole mistakenly addresses Tito as [[Film/TheWizardOfOz Toto]].

[[folder:Literature]]
* In ''Literature/BloodRites'', Trisha is a self-involved, superficial ditz who keeps getting Harry's name wrong on the set. [[spoiler: This ends up saving Harry from arrest, as she gives the police the wrong name when she falsely accuses him of attacking her.]]
* In Creator/StephenKing's ''{{Carrie}}'', the high school principal is an out-of-touch nebbish. He first calls Carrie "Carrie Wright" instead of White, and then misremembers her first name as Cassie.
* The early books in the ''Literature/{{Fearless}}'' series had a side character named Zolov, an old Russian chess player who repeatedly referred to Gaia as "Cindy", due to his Alzheimer's disease.
* In ''Literature/HarryPotter,'' [[OurGhostsAreDifferent Professor Binns]] is always so caught up in his lecture that he barely notices his students are even there listening to it. On the very rare occasion that they stay awake in class long enough to ask him a question he always gets their names wrong.
** In ''Literature/HarryPotterAndTheGobletOfFire'' [[BeleagueredAssistant Percy]] hero-worships his boss, Mr. Crouch, who always calls him "Weatherby" instead of "Weasley." Made a bit strange because he apparently knows Percy's father Arthur fairly well, though perhaps not well enough to know they're related?
* Sir George, the hero of ''Literature/DragonInDistress'', gets Princess Florinara Tansimasa Qasilava Delagordune's name wrong. No surprise. However, he actually gets it right later.
* Mr. D (Dionysus) Director of [[PercyJacksonAndTheOlympians Camp Half-Blood]] has been known to get camper's names right - but so rarely they are startled and wary when it happens.
* One of the stories in ''Literature/RealQuickFlashFic'' has the narrator keep getting 'triceratops' wrong.
* Waddington's inability to get other people's names right (he keeps calling Finch 'Winch' and 'Pinch') becomes an important plot point in ''The Small Bachelor'' by Creator/PGWodehouse.
* In ''StarTrekDepartmentOfTemporalInvestigations'', Professor [[InsufferableGenius Vard]] refers to Dulmur as Agent Duller, Agent Dummer, and Agent Dombler, among others.
* In ''LightNovel/ValkyrieIntoTheHeavens'', [[TeenGenius Daniel Logan]] is hard to pronounce with a Japanese accent, as a result [[TeenGenius Michiko Hoshimoto]] ends up calling him [[InSeriesNickname Danii...]] The name sticks.
* Early in ''WatershipDown'', there's a memorable scene where the Threarah accidentally refers to Hazel as "Walnut."

* ''Series/{{Blackadder}}''
** In the first series, [[BrianBlessed King Richard IV]] can never manage to remember his son Edmund's name. When he finally gets it right in the finale...
-->'''Edmund:''' Father, you called me "Edmund"!\\
'''Richard:''' WHAT? OH, SORRY, EDGAR...
** Combined with ThrowItIn in season 3, as Creator/HughLaurie actually screwed up his line.
-->'''Edmund:''' You can start by not calling me "Bladder".
* Jerry from ''Series/ParksAndRecreation'' is actually named Gary; the director got his name wrong on the first day and he wasn't assertive enough to correct him.
* ''Series/DeathInParadise'': In "An Unhelpful Aid", Sergeant Young keeps calling Fidel "Freddie".
* ''Series/DoctorWho'':
** Before the Doctor really got to like Ian Chesterton, he would call him things like "Chesterfield", "Chatterton", "Chesserton", and so on. The story is that this began as ThrowItIn of Creator/WilliamHartnell's line-hashings but was soon written into the character. After the Doctor [[TrueCompanions gets to like him]], he gets the name right, [[MaliciousMisnaming unless he's intentionally trying to upset him]] - except for a small and heartbreaking CharacterCheck where he accidentally mangles it in a {{Soliloquy}} at the end of "The Massacre" about how lonely he is, as if he's already forgetting what Ian's name really was.
** In "The Gunfighters", the Doctor constantly calls Wyatt Earp "Mr Werp" because no-one bothers to correct him.
** In "The Web Planet", InsectoidAliens the Menoptera struggle with human names, implicitly due to their very non-human intelligence and insect-like anatomy. Vrestin, the lead Menoptera in the story, mangles Ian's name into something like 'Hair-on'.
** At the end of "The Myth Makers", the Doctor refers to Kat'''a'''rina as "Katrina".
** Referenced in the DocuDrama ''Film/AnAdventureInSpaceAndTime'' when Hartnell is depicted as distractedly calling his new producer by his original producer's name.
* ''{{Friends}}'': Phoebe accidentally calls her boyfriend David by the name of her ex-boyfriend Mike. She tries to cover by claiming Monica calls Chandler 'Richard' (her ex-boyfriend) all the time and it's totally normal. Of course Chandler gets worried and Monica is annoyed given she's never done anything of the sort.
* On ''Series/{{Fringe}}'' Walter is incapable of calling Astrid by her correct name, except once when he was on drugs.
* On ''Series/LostGirl'', in the episode "Mirror, Mirror," Bo is perpetually (and drunkenly) incapable of calling Literature/BabaYaga by her correct name (calling her instead various things like "Baby [[Franchise/StarWars Yoda]].")
* On an episode of ''Series/{{MASH}}'', a visiting surgeon keeps getting BJ's name wrong. The only time he gets it right is when he's drunk.
* In ''MrBelvedere'', Heather's friend Angela constantly gets Mr. Belvedere surname wrong, calling him "Mr. Bellybutton", "Mr. Bellpepper", etcetera. Angela never said the same (wrong) surname twice.
* On one episode of ''TheNanny'', a photographer refers to C.C. Babcock as "Miss Boobcock", which gets reprinted in several places and even on a billboard.
* Trigger from ''Series/OnlyFoolsAndHorses'' always calls Rodney "Dave". The show had endless fun with what one might think would be a repetitive gag by coming up with variations such as:
--> '''Trigger:''' [Del might name his son] Rodney, after Dave over there.
* On ''Series/SesameStreet'', Big Bird often called Mr. Hooper "Mr. Looper", even after Hooper corrected him.
* On ''Series/StarTrekTheNextGeneration'', Lwaxana Troi regularly mispronounces Worf's name as "Woof".
* In ''Series/StarTrekVoyager'', Tuvok says "I am Vulcan", meaning "I am from Planet Vulcan" or "I am of the Vulcan race", but Neelix thinks his name is Mr. Vulcan.
* On ''Series/TheWestWing'', the GeniusDitz Lord John Marbury almost always refers to Leo, the White House Chief of Staff, as "Gerald." He does get Leo's name right at least once, so it may be ObfuscatingStupidity on Marbury's part, but it's hard to say.
* In ''Series/{{QI}}'', in the Series 7 episode "Gothic":
-->'''Stephen''': Alan, you're a zombie, you bite Jimmy ''(points to Jimmy Carr)'', Jimmy, you bite Jack ''(points to Jack Dee)'', Jack, you bite Mel ''(points to Sue Perkins)''.\\
'''Alan'''(points to Sue): Sue.[[note]]Mel Giedroyc was Sue Perkins' former comedy partner.[[/note]]\\

* A RunningGag in Brazilian soap ''Cheias de Charme''. LaughablyEvil villainess Chayene always misnamed one of the protagonists, Rosário, referring to her by many names which first syllable was "Ro-", except the correct one. Once she misnamed Rosário with two different names ''[[UpToEleven in the same sentence]]''.

'''Josh Matthews''': Maxine. \\
'''CM Punk:''': What did I say?\\

* ''Series/SesameStreet''
** During the time that Mr. Hooper was alive, Big Bird almost never got Mr. Hooper's name right. Commonly, he would call him "Mr. Looper".
** Similarly, when Mr. Handford appeared on the show, the other characters would call him "Mr. Handfoot", and he would have to correct them, seemingly to no avail.
** In an episode in which Freddy Flapman, a real estate agent, tries to convince Big Bird to move to a new habitat, a Main/RunningGag throughout that episode is Big Bird getting Freddy's last name wrong and Freddy having to correct him. Freddy ends up doing it to himself at the end of the episode.

** Which started out as a ThrowItIn when an actor said the wrong name during a performance.
* In "Theatre/AVeryPotterSequel", Harry and Ron call Hermione everything from 'Hermy-One' to 'Hermononucleosis'.
* In ''Theatre/{{Wicked}}'', G(a)linda often refers to Boq as "Biq," usually because she can't remember. He politely corrects her every time.
** Similarly, Professor Dillamond repeatedly called Galinda "Glinda" which initially annoyed her. When Dillamond was dismissed from the Shiz faculty as part of the growing mistrust of intelligent animals in Oz, Galinda chose to change her name to "Glinda" out of respect to the professor.
* The eponymous character in TheMusicMan goes by the name of Harold Hill, but the last time Marcellus saw him, he went by the name Gregory. As such, he calls him Greg for the rest of the show. Played with in that the "wrong" name is actually his real name.

* ''VideoGame/{{Atelier Iris 2|The Azoth of Destiny}}'''s Max addresses Felt by increasingly bizarre permutations of his name, at one point referring to him as "Klein" (the name of the protagonist from the previous Atelier Iris game). If corrected, he'll call him Felt for the remainder of the current conversation, so apparently he's just that bad with names.
* ''Videogame/BeyondGoodAndEvil''
** The heroine Jade first meets her sidekick Double H after freeing him from ElectricTorture. His brain is... [[EasyAmnesia a little fried]], and after hearing her mention the [[LaResistance "IRIS" Network]], he starts calling her "Miss Thyrus." (He also calls himself "Triple Z" at one point.)
** Jade herself once refers to the suspicious "Mr. de Castellac" who hired her on a mission (which was actually a charade aiming at establishing a contact between her and the IRIS Network) as "de Cadillac".
* In ''VideoGame/DestroyAllHumans: Path of the Furon'', Emperor Meningitis mistakenly addresses Crypto as "Klepto", due to being senile.
--> '''Meningitis:''' Pox? Is that you? What have you done with your body? And what's that with you? Oh, it's your little house boy, ''Klepto!''\\
'''Crypto:''' CRYP-TO.\\
'''Meningitis:''' Whatever!
* ''VideoGame/{{Okami}}'' proves that not even a ''God'' is immune to this trope. Most people you encounter find the name Amaterasu a bit too much of a mouthful to remember. The nicer ones will call you Ammy or (after a previous, respected alias) Shiranui. Less respectful ones settle for Furball.
* ''Franchise/SuperMarioBros''
** In ''VideoGame/MarioAndLuigiSuperstarSaga'', Luigi is often the victim of WhoIsThisGuyAgain. So characters use names like "[[BuffySpeak Mr. Green Mario Brother Guy]]" and "Loo...uh, some other guy!"
** Bowser does this in all three ''VideoGame/MarioAndLuigi'' games. Bowser has fixated on Mario as his greatest enemy, and always forgets Luigi's name. So Bowser uses names like "Green 'Stache" to refer to Luigi.
** In MarioAndLuigiBowsersInsideStory, Bowser himself gets this, as Broque Monsieur always refers to him as "Monsieur Turtle Bits".
** Used repeatedly in ''[[VideoGame/PaperMarioTheThousandYearDoor Paper Mario: The Thousand-Year Door]]''. The Puni elder thinks Mario's name is "Marty-o," the ancient mayor of Petalburg calls him "Murphy" due to his hearing problems, and the Yoshi who joins your party calls you "Gonzalez." That last one is {{justified|Trope}} because said Yoshi is born in a fighting-club type place, the Glitz Pit, where Mario's stage name is "the Great Gonzalez". (Mario didn't choose the name; his manager did.)
** The clueless "detective" Pennington, who thinks Mario is Luigi. ([[spoiler:In the sequence just before the final battle resumes, another character calls Mario by his proper name, and the detective is absolutely stunned at the notion of himself simply being ''wrong''.]])
** And also Zess T. who keeps referring to Mario with names such as "Stompy" and "Sir Crush-A-Lot" after he accidentally steps on her contact lenses.
** And Doopliss. [[spoiler:After he replaces Vivian of the Shadow Sirens, Beldam starts calling him "Freak-in-Sheet".]]
*** Doopliss himself calls almost everyone "Slick."
** In the ''VideoGame/DragonQuest'' crossover ''VideoGame/FortuneStreet'', Bowser occasionally refers to the Dragonlord as "Lizardboss".
* In ''VideoGame/SoulNomadAndTheWorldEaters'', Danette refers to the eponymous World Eaters as "[[BuffySpeak World... Thingies]]", due to her atrocious memory. She also never remembers Gig's name, much to his annoyance.
* Levi the Slasher of ''VideoGame/MagicalGirlLyricalNanohaAsPortable: The Gears of Destiny'', who becomes TheNicknamer because she has a hard time remembering people's name, even simple one's like "Fate", who she keeps mispronouncing as "Hate", before she decides to just call her "[[{{Doppelganger}} Original]]" since it's easier to remember for her.
* In the ''Videogame/FalloutNewVegas'' DLC Old World Blues, Dr. 0 (Zero) is commonly referred to as O (the letter). By the time you meet him, he's still annoyed by it but doesn't care to correct it. You can either convince him to take pride in his name Zero by noting that it reduces all numbers multiplied to it to zero or have him accept O as meaning the "Oh!" of scientific discovery.
* In ''Tales of Lagoona 2: Peril at Poseidon Park'' scatterbrained Mayor Abraham Tobias Peabody kept calling the granddaughter of the park owners Linda, Lorraine and every other L-name ''except'' her ''actual'' name, Leona. At one point he asked his aide "Bubbles" (real name Vinny) "Who's this Leona I keep hearing about?"
* Professor Hotchkiss, a recurring character from the NancyDrew games ''Treasure in the Royal Tower'' and ''Legend of the Crystal Skull'', calls Nancy by a different name every time, even in the same piece of dialogue. An expert on wood whom Nancy consults over the phone in ''Danger on Deception Island'' has the same problem.
* In ''VideoGame/SuperRobotWarsUX'', Richard Kruger tends to call Joey Jonathan, which is a reference to a time when Creator/JurotaKosugi voiced [[Manga/JoJosBizarreAdventure Jotaro Kujo]].
* Twice in the ''Franchise/KingdomHearts'' series.
** In ''VideoGame/KingdomHeartsII'', Captain Jack Sparrow calls Sora "Zola" in one scene. Sora gets annoyed and corrects him.
*** In the [[Manga/KingdomHeartsII manga adaptation]], Donald and Goofy were called "Ronald and Zoofy" by Yuffie. They didn't take that too well.
** A running gag in ''VideoGame/KingdomHearts3DDreamDropDistance'' is everyone referring to Lea by his former name, Axel. He ends up giving in when [[spoiler:Riku calls him by his former name after Lea saves a comatose [[DistressedDude Sora]] from Master Xehanort.]]
* In ''VideoGame/FinalFantasyXIV'', Inspector Hildibrand calls [[VideoGame/FinalFantasyV Gilgamesh]] "Gilligan". Gilgamesh tells him that if he can't get the whole name right, to just call him "Gil"; Hildibrand then starts referring to him as Greg. Gilgamesh ends up just going along with it.
* In ''VideoGame/{{Borderlands 2}}'', the player can find an ECHO recording of Handsome Jack when he was just a low-level Hyperion employee. His {{Jerkass}} boss Mr. Tassiter always calls him "John", which some players believe is actually his real name. However, after Jack takes over the company, he calls his own vice-president by the wrong name, which suggests that this is what was done to him as well.
* In ''Videogame/TheWonderful101'', [[TheRival Prince Vorkken]] always calls Wonder Red "Blunder Red" as well as referring to Earth as "Dearth". Despite being a villain, this is just him being clueless rather than malicious since [[spoiler:he gets Wonder Red's name right, but never really figures out the "Dearth" thing.]]
* Fei Fong Wong, the hero of ''VideoGame/XenoGears'' is frequently referred to by alternate names, typically [[spoiler: by people who've known [[{{Reincarnation}} past incarnations of him]] (example, Krellian calling him Lacan or Emeralda referring to him as Kim,) or by people who only know him by his SplitPersonality (Ramsus only ever refers to him as Id.)]] In addition, his mentor, Citan, is referred to as [[spoiler: Hyuga by all his former comrades from Solaris.]]

[[folder:Visual Novels]]
* ''Franchise/AceAttorney'':
** ''VisualNovel/ApolloJusticeAceAttorney'' also seems to be a frequent victim of this (rival prosecutor Klavier always calls him "Herr Forehead"), and there's even a scene where Apollo keeps getting the names of other characters wrong, prompting Trucy to say his name wrongly in the same way (such as calling him "Apololo" when he refers to Alita Tiala as "Alita Tialita").
** Morgan Fey keeps calling Detective Gumshoe "Gymshoe".
** Gumshoe continually calls Phoenix "Harry Butz" throughout the first game, not only getting Larry's name wrong, but using it on the wrong person. Mia also misinterprets Larry's name as Harry.
* In ''VisualNovel/LittleBusters'', every time Rin says [[RepetitiveName Sasasegawa Sasami]]'s name she manages to mess it up in some way, usually by saying something that sounds ''vaguely'' similar. The name ''is'' a mouthful, but only Rin, [[NotGoodWithPeople with a general lack of care about other people]] [[UnknownRival and Sasami in particular]] consistently gets it wrong.
* In ''VisualNovel/GrisaiaNoMeikyuu'' "Imouto" Robbie mangles the protagonist's name hopelessly and in ''VisualNovel/GrisaiaNoRakuen'' he also alters the name Sakaki Yumiko into Sakuaki Jubico somehow. And this is the guy on Yuuji's squad that actually does speak Japanese.
[[/folder]]

[[folder:Web animation]]
* In ''WebAnimation/DoraleousAndAssociates'', a RunningGag of the series is that no-one outside the the Associates can pronounce his name right, with "Doralingus" being the most popular pronunciation.
* In ''Machinima/MeleesEnd'', Marth constantly mixes up people's names because he's a complete [[TheDitz ditz]].
* When Strong Bad isn't doing MaliciousMisnaming in ''WebAnimation/StrongBadEmail'', he's doing this. In "long pants", he misreads "Clancy" as "Clanky", and in "geddup noise" he reads "marc baroni AZ" as "Macaroni from A to Z".
[[/folder]]

[[folder:Web comics]]
* In ''Webcomic/DMOfTheRings'', nobody could keep any of the names straight. Notable ones include Aragorn referring to Théoden as "King Crazypants", mixing up Sauron and Saruman, and forgetting the names of their own party members. Rivendell is Rivertown or [[ArchieComics Riverdale]], Théoden is Theogan, and the Nazgûl are [[CrowningMomentOfFunny Nargazoids]].
-->'''Aragorn:''' [[Franchise/EvilDead Hail to the king, baby]]! Aragorn, son of Andúril is back!\\
'''DM:''' ... Andúril is the name of your ''sword'', dumbass.
* ''{{Drowtales}}'' has Zith, a cameo character who [[http://www.drowtales.com/mainarchive.php?sid=9470 chronically mispronounces everyone's names]], to the point that the page has an author's note on the bottom explaining all the misspellings were intentional. Her concept art features her calling Quain'tana "Quainana" much to the Ill'haress' disdain, but seems to be [[BunnyEarsLawyer good enough at her job otherwise]] given Quain's intolerance for incompetence. Also something of a FandomNod since many members of the comic's forum have trouble spelling character's names.
* ''Webcomic/ElGoonishShive'': Bunnies (that is, [[FanCommunityNicknames EGS fans]]) do this sort of thing a lot on the forum. The most common seems to be calling Susan "Sarah" or Sarah "Susan".
* Characters in ''Webcomic/MenageA3'' fairly frequently mangle each others' names, usually as a sign that someone is or was drunk, has just met somebody else, or is just plain careless -- sometimes all three. Notably:
** [[http://www.ma3comic.com/strips-ma3/didi!_you_are_in Zii gets Gary's name wrong shortly after meeting him.]]
** [=DiDi=] has so many boyfriends that she can't remember their names. For example, she calls Erik "Armand", "Philippe", "Derick" and "Jerry".
** Sonya mangles new character Peggy's name heavily [[http://www.ma3comic.com/strips-ma3/here_to_do_a_good_deed here]] and [[http://www.ma3comic.com/strips-ma3/didi_haj_dibsh here]], simply because she's very drunk at the time. (This also generates an InJoke reference to author/artist Giz's past work on ''Webcomic/PennyAndAggie''.) She still hasn't got Peggy's name quite straight [[http://www.ma3comic.com/strips-ma3/i_am_in_a_bind_-_start_of_vol_6 the next morning]].
* Reginald from ''Webcomic/{{Nedroid}}'' takes this to the extreme when, at the end of an evening of romance, he accidentally calls his date Becky "Lord Voldemort".
[[/folder]]

[[folder:Web original]]
* In Blog/AskKingSombra, a Running Gag is that Sombra [[http://25.media.tumblr.com/437baa39def8db467dd8e843102f07b5/tumblr_mkpmb7Azd71rj4ht7o10_250.png can never remember Coffee Talk's name]], mangling it into things like Hockey Puck, Toffee Socks or Coughing Rock.
* The [[LetsPlay/MenDrinkinCoffee MenDrinkin'Coffee]] often do this to themselves, calling themselves "the Coffeemen," "Coffedrinkers," "Men who also drink coffee," and "the three dumbasses," to name a few.
[[/folder]]

[[folder:Western animation]]
* In the ''WesternAnimation/DextersLaboratory'' episode "Old Man Dexter", as Dexter is deemed too young to watch late-night TV, he scientifically ages himself... [[GrumpyOldMan a little too much.]] As such, senility kicks in as he asks his sister to help him up on the living room couch.
-->'''Dexter:''' A little help there, um... [[SpeciesLostAndFound Dodo?]]\\
'''[=DeeDee=]:''' [=DeeDee=].\\
'''Dexter:''' [[BabyLanguage Daa Daa?]]\\
'''[=DeeDee=]:''' [=DeeDee=].\\
'''Dexter:''' [[ToiletHumour Doo Doo?]]\\
'''[=DeeDee=]:''' [=DeeDee=].\\
'''Dexter:''' Yeah thanks, Billy.
* WesternAnimation/{{Duckman}} constantly forgets the name of his son, Mambo, calling him by other unusual or ridiculous names like La Bamba and Mandingo. In one episode, he forgets Charles' name instead.
* On ''WesternAnimation/TheFairlyOddParents'', several characters have forgotten Timmy's name. [[AsianAirhead Trixie Tang]] is the one that comes to most fans' minds, but several others have forgotten at one point: Cosmo, his parents, Adam West, and Quddus (in the TRL interview).
* One ''WesternAnimation/HouseOfMouse'' animated short, "computer.don", was about Donald Duck buying a talking personal computer that can recognize people's names, but the computer misunderstands Donald's SpeechImpediment and consistently refers to him as "Duo."
* "[[WesternAnimation/SuperMarioWorld That's]] '''''[[WesternAnimation/SuperMarioWorld WIZARDHEIMER!!!]]'''''"
* In "The Greatest Story Never Told" of ''WesternAnimation/JusticeLeagueUnlimited'', episode centerpiece ComicBook/BoosterGold is constantly referred to or otherwise mistaken for Green Lantern despite his gold-and-blue color scheme.
* ''WesternAnimation/TotalDramaIsland'': Lindsay is getting everybody's name wrong. Although she can usually remember somebody's name if they're (at the moment) important to her. For example she remembers Heather's name throughout the whole TDI season; when she calls her "Hannah" in the special Heather is clearly shocked, because is means Lindsay is no longer her puppet. It's PlayedForLaughs much more in ''World Tour'', where she just can't get her boyfriend's name right. She calls him Noah, a character she's had no on-screen interaction with. Ergo, she can remember a name or a face, but never both!
* In ''WidgetTheWorldWatcher'', the male elder keeps forgetting and mispronounces Widget's name every time they meet.
* ''{{WesternAnimation/Motorcity}}'': Texas frequently calls Julie by other names, such as "Babs" or "Lisa." He does call her Julie every now and then.
* In ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' Billy gets a new friend (a parody of HannaBarbera characters) who introduces himself as "Wiggy Gee Jed". Billy calls him "Wiggy Jiggy Jed".
* Characters often get WesternAnimation/BeavisAndButthead's names wrong, such as "Buffcoat and Beaver", "B and Butter", and "Buttbrain and Beatrice".
* In ''ThePenguinsOfMadagascar'' episode "Misfortune Cookie", Julien keeps getting Rico's name wrong and calling him "Chico" or "Freako".
* A RunningGag in ''WesternAnimation/HeyArnold'' is that Helga's parents always call her by her older sister's name: Olga.
** Arnold himself also gets misnamed at times, usually by characters that don't know him too well.
* For some reason, a popular gag in western animation is to have grandparents misremember their grandchildren's name as "Billy". ''WesternAnimation/SouthPark'' and ''WesternAnimation/DextersLaboratory'' are two shows that have done this.
* "[[SpongebobSquarepants It's ''Tennisballs!"]]
* ''WesternAnimation/{{Daria}}'''s title character has this by way of PhraseCatcher--in early episodes people she didn't know had a tendency to always call her something else. In one later episode a substitute thinks she has a "hippie name" and insists on calling her "Darlene."
** Originally [[HippieTeacher Mr. O'Neill]] could never remember any of his students' names, but that [[EarlyInstallmentWeirdness only lasted about two episodes]] before the writers decided it wasn't that funny.
* One episode of ''WesternAnimation/{{Rugrats}}'' had Grandpa Lou's sister come to visit. The entire time, she kept calling Didi different names. When she leaves and ''Stu'' accidentally calls her a different name, she freaks out and shrieks "It's ''DIDI!''"
** This actually causes most of the problems in the episode "Angelica Breaks A Leg" - the doctor there keeps calling the Pickles "Peaches" and ends up getting X-Rays mixed up as a result.
** In the movie, a news reporter gets all the babies' names wrong: "Young Tammy, baby Dale, the twins Bill and Jill, little Chunky, and poor Amelia."
* In the ''WesternAnimation/WhatACartoonShow'' short "Snoot's New Squat", Snoot's superior officer keeps getting his name wrong, calling him "Agent Squint" and the like.
* In the ''WesternAnimation/Ben10AlienForce'' episode "Alone Together", Ben introduces himself to Reinrassic III, one of the Highbreed, by saying "I'm Ben. Ben Tennyson". Reinrassic III keeps calling him "Ben Ben Tennyson" as a result from that point onward.
* ''WesternAnimation/AdventureTime'': Tree Trunks keeps referring to Lemongrab as "Lemon Carb". This is not malicious, but more an indication of her borderline senility.
* Mr. Maellard, owner of the park, on ''WesternAnimation/RegularShow'' messed up Benson's name constantly, however after Benson saves his life in "Benson Be Gone" he begins to say his name correctly.
* The titular Mayor of ''WesternAnimation/TomGoesToTheMayor'' never remembers Tom's name when he encounters him at the beginning of each episode. He usually rattles off some potential T names or words, until Tom corrects him. Further, Tom's name is almost never correctly spelled when written down, though it always phonetically correct.
* The turtles consistently fail to remember Baxter Stockman's name in ''WesternAnimation/TeenageMutantNinjaTurtles2012''.
