%%* ''Series/{{Castle}}'': Richard Castle is this, along with his own mother, who is arguably worse than he is. Alexis, Castle's teenage daughter, is undoubtedly the most mature of the three.

%%* ''WesternAnimation/DespicableMe'': Gru and Vector are not true adults, Gru has {{Freudian Excuse}}s and Vector still toys with his superweapons. Gru will become a true adult after the movie.

* While most Pokemon in the ''Anime/{{Pokemon}}'' anime tend to gain a more mature and aloof personality after evolving, there have been exceptions:
** Compared to the rest of Ash's Kalos mon, Goodra remained as playful as it was as a Goomy, which lends to several characters recognising it as such just from behaviour. When it reunites with it's childhood friend, Wooper, it goes into an excitable fit, despite now being over ten times it's size.
** Ash's Lycanroc in the ''Sun and Moon'' series tends to act as much like friendly and energetic puppy as it's Rockruff form and even has a {{Friendly Rival}}ry of sorts with the unenvolved Litten (who maintains a similar scrappy attitude throughout evolving to Torracat and Incineroar).
** Kiawe's team consists of the enormous powerhouse Turtonator and the evolved Alolan-forme Marowak. Both engage in the class' fun and games as much as the cuter Pokemon and are often seen bickering or scrapping like childish siblings.
** Perhaps most surprisingly, the OlympusMons caught by the main cast from the same series nearly all have the same disposition. Perhaps most blatant is Poipole, an elusive Ultra Beast that acts like a {{Keet}} and a little sibling to Pikachu. It returns later during the Alola League evolved into Naganadel, a giant fierce looking wasp/dragon hybrid creature with enough battle prowess to challenge ''Tapu Koko'', and ''still'' acts like a CheerfulChild, smiling and dancing at the audience and other Pokemon during intervals.

* In ''Literature/{{Diary of a Wimpy Kid}}'', almost all of Rowley's friends are little kids.

%%* Despite being an over-1100 years old Time Lord, the Doctor in ''Series/DoctorWho'' demonstrates a few of these trait, in particular the Eleventh Doctor who is a ManChild and very close to children.

[[folder:Films]]

%%* Taken in a somewhat more serious tone with protagonist Buck from ''Chuck and Buck'', who appears to have an endless supply of blow pops, a room filled with children's games and toys, and exhibits other odd habits throughout the movie. Granted, [[spoiler:his childhood wasn't exactly normal]].
* Buddy in ''Film/{{Elf}}'', in which most of his actions are naive, ''adult child''-related, not elf-like. In fact, he is just about an opposite to all of the other elves in the film.
* Maria from ''Film/TheSoundOfMusic'' loves singing and dancing and being a free spirit. This concerned the nuns at the Abbey, as she at first wanted to be a nun.

%%* ''WesternAnimation/DespicableMe'': Gru and Vector are not true adults, Gru has {{Freudian Excuse}}s and Vector still toys with his superweapons. Gru will become a true adult after the movie.
%%* Bert in ''Film/{{Mary Poppins}}'' acts free spirited and childlike at times, but usually in an endearing way.
* Brand in ''{{Film/The Goonies}}''. He spends the first act of the film trying to keep his little brother and his friends in line, but he eventually gets swept up in the adventure as much as the rest of them.

%%* The ''Literature/XWingSeries'''s Wes Janson is often said to be like this; he enjoys life wholeheartedly and likes pranks, puns, and having fun without caring about dignity. A fellow pilot once says that getting him up to the mental age of twelve, maybe thirteen would be impossible. For all that, though, he does know how and when to put on a straight face and get serious. In combat, he's actually something of a ColdSniper.

* Eldon from ''Literature/TheColdMoons'' is a simple, almost childish adult. His low-maintenance personality and active imagination makes him great with cubs. After he steps down as the SketchySuccessor of the badgers, he becomes the caretaker of the cubs along the journey to Elysia. The cubs follow Eldon without any trouble.

* Gordy the janitor on ''Series/NedsDeclassifiedSchoolSurvivalGuide'' who helps with many of the main characters' [[ASimplePlan simple plans.]]

%%* Lorelai Gilmore of ''Series/GilmoreGirls'' sometimes was this, especially in earlier seasons. Kirk was a more severe example.

* Despite being an over-1100 years old Time Lord, the Doctor in ''Series/DoctorWho'' demonstrates a few of these trait, in particular the Eleventh Doctor who is a ManChild and very close to children.
** As befitting the Doctor's foil, the Master (especially when played by Creator/JohnSimm) is something of a PsychopathicManchild.
** The Doctor is the man who responded to Amy Pond saying "[[SillyRabbitIdealismIsForKids I grew up]]" with "Don't worry, I'll soon fix that" and who uttered the following quote back in his Fourth Doctor days:
--->'''The Doctor:''' There's no point in being grown up if you can't be childish sometimes.
** The Twelfth Doctor begins showing some of these traits in his second season travelling with Clara Oswald, dressing more casually and gaining an interest in rock and roll and electric guitars. In one episode he also openly addresses Clara as he would a teacher.
%%* FDR from the backwards episode of ''Series/{{Seinfeld}}''. He wants Kramer to drop dead, and he wishes on anything he can (wishbone, fallen eyelash, shooting star, birthday cake) that Kramer would drop dead. [[spoiler: This is because Kramer hit him with a slushball two years earlier.]]
%%* ''Series/{{Psych}}'' has main character Shawn Spencer.

%%* [[Series/{{Castle}} Richard Castle]] is this, along with his own mother, who is arguably worse than he is. Alexis, Castle's teenage daughter, is undoubtedly the most mature of the three.
* [[Series/PeeWeesPlayhouse Pee-Wee Herman]], obviously.

%%* [[Series/TheAdventuresOfPeteAndPete "Artie! The Strongest Man...In The World!"]]
* Cliff Huxtable of ''Series/TheCosbyShow'' may be a doctor, but he often has childlike traits. Mostly he uses them only around children.
%%* In ''Series/TheKidsInTheHall'', Bruce tended to play these kind of characters. His monologues tended to be grown men with overly naive and idealistic views and prone to flights of fancy, including [[https://www.youtube.com/watch?v=8avnmkaJI3s "If Elvis Were My Landlord"]].

* Gibson in ''Series/ANTFarm'' acts in this way most of the time. He seems to have a mental age below that of the kids - even assuming the [=ANTs=] were regular highschoolers, let alone of an age when they'd normally be at middle school.

* Fran Fine from ''Series/TheNanny'', which is one reason she's such a great nanny to the Sheffield children.
%% * [[HotWitch Winnie Goodwin]] from the short-lived ABC show ''Series/FreeSpirit1989''.
* ''Series/{{NCIS}}'': Abby is rather childlike in a good way (cute, sweet, innocent, cheerful etc.) In one episode she has to watch over a teenage girl whose friend was kidnapped (to make sure she didn't get kidnapped as well). Unsurprisingly, they hit it off right away.

[[folder:Theater]]
* All the human characters of ''Ms. Bleep'' have regressed to this, having spent an unknown amount of time "trapped in school in perpetuity" with a robotic [[MisplacedKindergartenTeacher kindergarten teacher]] that gives them an electric shock every time they leave or misbehave. Cindy, the resident brown-noser, doesn't even seem to remember the outside world or the fact that she's an adult, and [[spoiler:has no way of comprehending the death of a fellow captive.]] The other two are trying to escape, but they're still jarringly childlike in regard to such subjects as cookies and naptime.
* Mary in ''Vanities'', mainly due to her [[DarkAndTroubledPast difficult childhood]]. She finally matures in the finale of TheMusical.
* Weston Hurley in Lanford Wilson's ''The Fifth of July'' could certainly qualify.
[[/folder]]

* Alistair from ''VideoGame/DragonAgeOrigins''. While courageous and noble and all, his main party gifts are action figures. The Feast Day DLC gives him Grey Warden Hand Puppets that you can watch him play with.
-->'''Alistair''' (upon pulling out his dollies): "What's that? You want me to ''be quiet''?!"
* Possibly Lord Roth from ''VideoGame/InfiniteSpace''. Well, he is really competent that he becomes one of the top zero-G dogs in the universe, but personality-wise, he fits this trope.
* ''[[Characters/MrDriller Taizo Hori]]'' from ''VideoGame/MrDriller'' and ''VideoGame/DigDug'', is as energetic and dumb as a little kid, he even throws childish tantrums when he doesn't get proper recognition. Quite funny considering he's the oldest of the main cast being ''45 years old'' It's probably the reason why his wife left him.
* ''VideoGame/{{SoulCalibur}}'''s Xianghua has a prone move that for all intents and purposes, appears to be a childish tantrum.
* Any adult Sim on ''VideoGame/TheSims3'' that has the "Childish" trait will play with toys, get along better with children, hate doing adult things (like working), and like to make faces at people. This trope also counts when it is a Teen or Elder sim. They are also able to fish in swimming pools.

* In ''VideoGame/FinalFantasyVII'', Barret is 35 and generally interacts equally with Cloud, Aeris and Tifa, who have an average age of 21 (and act like it). This is especially notable with Cid, who's 32 and makes it clear that he views Cloud, Aeris and Tifa as kids.
* In ''VideoGame/DiscoElysium'' it's possible for your middle-aged protagonist to build a natural rapport with characters that are roughly half his age or less, such as the gang of youngsters trying to start a nightclub or Cuno, the local {{delinquent}}. [[spoiler:When your old partner reminds you that you were a former high school gym teacher, Kim notes how that must be why you're so "juvie".]]

* Taiga Fujimura in ''VisualNovel/FateStayNight''., who despite being an adult is almost always in the company of people younger than her, and her maturity level is the same as theirs if not younger. This means that [[ShooOutTheClowns she gets kicked out of the route]] around halfway through each time. Notable childishness: berserker fury over being called Tiger, challenging Saber to a fight and bursting into tears when she loses, the most overboard expressions in the game, and switching the labels on soy sauce and oyster juice. Notably, the visual novel shows that she only acts immature at home and is generally much more competent as a teacher.
* ''VisualNovel/DanganronpaTriggerHappyHavoc'' has Yasuhiro Hagakure, who's 20 years old while the other main characters are high school students (he was held back a few years). Despite being the oldest of the students, he's probably even more ditzy and immature than the rest of them.

* In the LighterAndSofter Comicbook/{{Watchmen}} parody, ''[[http://envyskort.deviantart.com/gallery/#/d1y1h8p G-rated Watchmen]]'', the Watchmen characters are given the behavior and personalities of young children. The authority figures are treated as the "grown-ups", despite being around the same age as the main characters.
%%* For the God of [[ShockAndAwe Lightning]] and Sky, [[{{Godquest}} Volt]] can act like this at times. [[http://nixshadow.com/mspfa/?s=153&p=74 Case in point]].
%%* Ever since his transformation, {{Ratfist}}'s [[spoiler: severed tail]] has been an embodiment of his id, and will spit out every last thought that crosses his mind, conscious or otherwise. Often this hints that he never really grew up (which may explain why he's prancing about in a costume fighting crime); sometimes the hints are fairly benign ("I want to eat an entire pizza") and sometimes it suggests that ''kids can be really fucking terrifying''.
%%--->'''Ratfist''': Wait. I'm not afraid of that cat!
%%--->'''Milt''': Hey, neither am I!
%%--->'''[[spoiler:Tail]]''': Me neither! Let's eat it!
%%* Jared from ''Webcomic/ManlyGuysDoingManlyThings''. Exhibit A: [[http://thepunchlineismachismo.com/archives/905 here]].

* Pinkie Pie in ''Blog/SliceOfLife'', who ends up being a confidante to the Cake twins as a result.

%%* Will from ''LookAVlog'' has elements of this, particularly when interacting with [[DeadpanSnarker Emily]].
%%* WebVideo/RhettAndLink have pulled some rather childlike shenanigans. In fact, their entire career is based on acting silly.
%%* The author of ''Webcomic/{{Hyperbole and a Half}}'' according to herself in [[http://hyperboleandahalf.blogspot.com/2010/06/this-is-why-ill-never-be-adult.html this entry]].

%%* WebVideo/TheNostalgiaCritic is both this and a PsychopathicManchild.
%%** His other alter-ego, Chester A. Bum, is even more qualified for this role.
%%** Also, WebVideo/TheNostalgiaChick's ''WesternAnimation/MyLittlePony'' episode showed that her best friend [[ButtMonkey Nella]] still has (and plays with) her my little ponies. Things got dark pretty quickly though, we only see a bit but one is a hooker with a heart of gold, the stranger looking ponies are treated as freakish abominations, and there is at least one death (implied to be a suicide).
%%** Most of the Website/ChannelAwesome crew fits this to one degree or another. [[WebVideo/AtopTheFourthWall Linkara]] stands out, given that he collects Power Ranger toys.

%%* Jesse Cox of ''WebVideo/OMFGCata'' has frequently been called the most immature person ever by his comedy duo partner Creator/TheCynicalBrit, and he probably is.
* It's deconstructed in ''WebVideo/MyLittlePonyTheMentallyAdvancedSeries'': being One of the Kids does not make Rainbow Dash a good babysitter, as she encourages and takes part in kids' shenanigans, no matter how bad an idea it is. She got banned from babysitting her cousin's daughter because they ate ice cream for dinner and it ended with Dash hospitalized and the kid sick from the ice cream. It's later revealed that she has a court order barring her from being alone with children because of it, which nearly got her in trouble in ''Rainbow Dash Presents: Bittersweet''. [[spoiler:She got off because she wasn't ''intentionally'' watching the foals alone due to them deciding to run away from home.]]

%%* ''WesternAnimation/TheFairlyOddparents'' has Timmy's parents, [[ParentalNeglect who would rather go out and have fun than take care of Timmy]].
%%** In the LiveActionAdaptation, Timmy himself becomes this so he can keep his fairy godparents.

* Captain Sunshine from ''WesternAnimation/TheVentureBrothers'' is a superhero whom is a parody of Franchise/{{Batman}}. [[MistakenForPedophile Everyone thinks he's a pedophile]] due to the way he acts around young boys; as it turns out he's just a big ManChild who's lonely after his first Wonderboy died.

* ''WesternAnimation/MoralOrel'' offers a rather creepy version of this. Doughy's parents, who must be somewhere in their ''thirties'', [[{{Manchild}} act, and dress like they're still in High School.]] This extends to their parenting, (if it could be called that) where they treat Doughy more like an AnnoyingYoungerSibling, than a son.

* ''WesternAnimation/RockosModernLife'': In "Old Fogey Froggy", Mr. Bighead suffers a midlife crisis and attempts to play this role while hanging out with Rocko and his friends.
* Jake from ''WesternAnimation/AdventureTime''. He's a dog, but he's twenty-eight in dog years, and his best buddy is his teen-aged step-brother Finn.
* PlayedForLaughs on ''WesternAnimation/YoungJustice2010'', when [[ComicBook/{{Shazam}} Captain Marvel]] is tasked with mentoring the Team. He adores them and repeatedly tries to hang out with them on missions and social events, while they treat him as either an intrusive spy from the Justice League or, at best, the way most teenagers would treat a grown man who acts like a ten-year-old. The joke, of course, is that Captain Marvel ''is'' a ten-year-old HenshinHero who transforms into [[OlderAlterEgo an adult superhero]], but neither the Team nor most of the Justice League know that. This becomes a serving point for debate of if age should be a factor in recruiting new members, as well as recruiting Marvel or even having him involved in League affairs once the truth comes out.

* Soos from ''WesternAnimation/GravityFalls'' is still into things like laser tag and getting pizza at [[SuckECheeses Hoo-Hah Owl's Pizza-ma-tronic Jamboree]], and is frequently up for any fun Dipper and Mabel get into, whether it's investigating the supernatural or bedazzling his shirt to make him a human disco ball.
* WesternAnimation/JohnnyBravo is a main-character example, who interacts with the neighborhood kids like he's one of them. He also lives with his mother like a child, but he's clearly an adult.
* ''WesternAnimation/TheAmazingWorldOfGumball'':
** Richard spends a lot of time with his sons and sometimes his daughter, mostly because he's a ManChild BumblingDad who doesn't have a job (and actually can't have a job because the universe will be destroyed if he does).
** Rocky, the school's resident man of a thousand jobs (including school bus driver, cafeteria worker, and janitor) is in his early thirties, but is a friend to all the students and always jokes around with them.
* This appears to be WesternAnimation/UncleGrandpa's job. If he's interacting with someone he doesn't live with, he's probably helping a kid.
* The main character of ''WesternAnimation/BoJackHorseman'' is a deconstruction of immature grown men. Being in his fifties but having the mind and outlook of a teenager means he has an uncanny ability to relate to younger people and bond with them, but it also makes him irresponsible and much, ''much'' more susceptible to doing really silly things that put him in a bad spot or ruin his relationships with others. Plus, by hanging out with tweens and teens, people see him as a creepy, pathetic old man ([[ByronicHero which they might be right about]]).

* ''WesternAnimation/ElinorWondersWhy'': Beatriz, from "A Wonderful Journey", likes to hang out with the kids and acts like a kid in some ways, like pretending to be a frog.
* Bandit from ''WesternAnimation/{{Bluey}}'' can be a perfectly functional adult, but most of the time we see him he's with his kids, joining in whatever silly game they're playing at the moment. Sometimes it even weirds out other adults on the show.

* Adults in ''Manga/LuckyStar'' are often this, to the annoyance of [[GenreSavvy Konata.]]
** Her homeroom teacher Nanako Kuroi is envious about students needing to wear uniforms, as she is found choosing clothes a chore. And one time, she decided the game when her favorite baseball team lost did not exist at all. Due to being single, she also spends a lot of her free time on {{MMORPG}}s, where she frequently interacts with her student Konata; though unlike the latter, Nanako is wise enough not to sacrifice working time for playing time, and she'll even use the in-game chat feature to remind Konata to study.
** Konata's cousin Yui Narumi is a traffic cop who DrivesLikeCrazy, and is very cheerful and energetic. Despite being a young woman, she can also be immature, especially compared to her teenage sister and cousin, who she often visits just to hang out with them even though she's older.

%%* Midori Sugiura from ''Anime/MyHime'' is a twenty-something teacher and waitress with a love for history and the occult, but repeatedly tells everyone she knows that she's [[YoungerThanTheyLook really only 17]] (and also, evidently, Manga/SailorMoon.) Nobody believes her in either case... especially [[SchoolNurse Nurse]] Yoko, one of her former college mates.
%%** However, it's highly likely that [[spoiler: Midori might have ''faked'' at least half of her One of the Kids tendencies, using it as ObfuscatingStupidity.]]
%%** In Anime/MyOtome, the sequel to ''Anime/MyHime'', that version of Midori also insists that she's 17. However it's for a much darker reason: [[spoiler: Her people are suffering from a degenerative disease, and resorted to technology to halt it. 17 was the age she was when she started her "treatment"]]
* ''Manga/RanmaOneHalf'' gives us Hinako Ninomiya, the English teacher that is in her late twenties, [[OlderThanTheyLook looks around twelve]], and behaves like a six/seven year old would. Although she only acts in her child form. [[DualAgeModes In her adult form]] she's usually all business, unless she stays in it for too long.
* ''Manga/{{Yotsubato}}'' has Yanda, who during his first meeting with Yotsuba proves that he's just as immature as she is -- and often goes too far in making himself Yotsuba's SitcomArchnemesis by stealing her food and calling her names -- and [[TheBigGuy big guy]] Jumbo, who starts a one-sided competition with ten-year-old Miura over visiting Hawaii. Yotsuba's father, while more responsible than the other two (being Yotsuba's legal guardian and all), is not above playing along with her antics. However, the three are perfectly capable of speaking calmly like normal adults when the kids are not around.
* Kasugano-sensei from ''Manga/{{Sketchbook}}'' acts very childish at times, which also gets commented on by the students in her art club.
* Yoshinoya-sensei in ''Manga/HidamariSketch'' is a very good example. She considers herself a young woman before even thinking of herself as a teacher, delights in [[CosplayOtakuGirl dressing up in costumes]], and is prone to odd looks from her students. Her principal is always ''extremely'' disgusted with her, and HilarityEnsues whenever they meet.
* Kaneru from ''Manga/DoujinWork'' is an {{office lady}} with a very childlike disposition, which makes her bond with TokenMiniMoe Sora very well.

%%* Mrs. Miyaji, and most of the other adults in ''Anime/{{FLCL}}''.
* Jack Rakan in ''Manga/NegimaMagisterNegiMagi'' managed to become a major player in the kid/teen-filled Ala Alba. Keep in mind, he's old enough to be considered an OldSoldier. The other Ala Rubra members (Eishun, Albireo) by contrast had a sense of aloofness to the main cast.

* While Daikichi Kawachi has this as an InformedFlaw in ''Manga/BunnyDrop'', [[ChildrenRaiseYou he quickly grows out of it]] raising Rin. Rin's mother Masako on the other hand, is a much clearer example, with Rin's biological father (and Dankichi's grandpa) stating in a will that Masako wasn't yet mature enough to be a mother, and Daikichi's impression being that Masako simply doesn't realize the problems she's leaving to other people by not taking Rin.
* ''Manga/SoulEater'':
** Spirit frequently acts more childish and inappropriately than the teenage cast. Marie also counts, though is respected by her pupils.
** [[BigGood Shinigami]] also tends to act like this, although it's implied much of it is ObfuscatingStupidity as to not scare his students.

* In ''Manga/ACertainScientificRailgun'', Mikoto Misaka is known among people who are close to her for having some ''really'' childish tastes (such as an obsession with a frog mascot marketed at three-year olds), not to mention her childish inability to accept defeat when fighting [[AntiMagic Touma]]. Kids notice this, [[FriendToAllChildren which is one of the reason she works well with them]].
%%* Ryuuji's mother Yasuko from ''Literature/{{Toradora}}'' refers to herself as "Yacchan", and makes childish requests like wanting her name written in ketchup on her omelettes.
%%* Keroro from ''Manga/SgtFrog'' has some attributes of this, including throwing the occasional temper tantrum.

%%* Masane Amaha from ''Anime/WitchBlade''. Good thing her daughter is WiseBeyondTheirYears.
%%** As time goes on, she [[CharacterDevelopment gets better.]]
* [[IntangibleMan Sein]] of ''Franchise/LyricalNanoha''. She could act her age if she needs to, it's just that she usually doesn't. She even does an all-out temper tantrum when she gets caught red-handed doing one of her pranks in ''[[Manga/MagicalGirlLyricalNanohaVivid ViVid]]''.
--> '''Nove:''' Geez... it makes me feel depressed when I realize that you're supposed to be older than myself.

* ''Literature/DragonCrisis'': Eriko is unable to cook and irresponsible, leaving her younger cousin Ryuuji to be the grown-up one.

* Handa, the 23-year-old main character of ''Manga/{{Barakamon}}'', is one of these, often hanging out with seven-year-old Naru and her friends.
* Kei's mom in ''Manga/TheBeautifulSkiesOfHououHigh''. She's also considerably ignorant to go along with her immaturity.
* Kagura from ''Manga/{{Gintama}}'' is often showing hanging around the neighbourhood children and playing games with them. Arguably Sougo too since he acts very childishly sometimes, especially when he's around Kagura which can cause them to descend into playground-scale wars.
* In ''Manga/OnePiece'' 19-year-old Luffy and 8-year-old Momonosuke get into several funny and heated arguments because Luffy is just as immature as Momonosuke and probably even dumber.
* While most Pokemon in the ''Anime/{{Pokemon}}'' anime tend to gain a more mature and aloof personality after evolving, there have been exceptions:
** Compared to the rest of Ash's Kalos mon, Goodra remained as playful as it was as a Goomy, which lends to several characters recognising it as such just from behaviour. When it reunites with it's childhood friend, Wooper, it goes into an excitable fit, despite now being over ten times it's size.
** Ash's Lycanroc in the ''Sun and Moon'' series tends to act as much like friendly and energetic puppy as it's Rockruff form and even has a {{Friendly Rival}}ry of sorts with the unenvolved Litten (who maintains a similar scrappy attitude throughout evolving to Torracat and Incineroar).
** Kiawe's team consists of the enormous powerhouse Turtonator and the evolved Alolan-forme Marowak. Both engage in the class' fun and games as much as the cuter Pokemon and are often seen bickering or scrapping like childish siblings.
** Perhaps most surprisingly, the OlympusMons caught by the main cast from the same series nearly all have the same disposition. Perhaps most blatant is Poipole, an elusive Ultra Beast that acts like a {{Keet}} and a little sibling to Pikachu. It returns later during the Alola League evolved into Naganadel, a giant fierce looking wasp/dragon hybrid creature with enough battle prowess to challenge ''Tapu Koko'', and ''still'' acts like a CheerfulChild, smiling and dancing at the audience and other Pokemon during intervals.
* Ilulu of ''Manga/MissKobayashisDragonMaid'' is stated to be the same age as Tohru, roughly the dragon equivalent of a sixteen year old. However, due to past childhood traumas, [[{{Manchild}} she's emotionally stunted]] and she's shown to vastly prefer the company of younger children such as Kanna and her elementary school friends. She ''can'' be mature, but even then her preference for the company of kids comes through. Her choice of job, part-timing at a candy store, allows her to contribute to the household, as Tohru insisted she do, but also means she can work in a place children often visit.
-->'''Ilulu:''' Kids... you know... I like them... I like playing with kids... but when you have a job you can't play... so at least I want to be in a place where kids look like they're having fun... is what I thought.
* Deconstructed in ''Anime/NeonGenesisEvangelion''. Misato is in her late 20s and interacts fairly equally with young teenagers, but it's a result of her own emotional damage and failure to grow up, and incorporates some rather unwholesome sexual elements as well.
* Sawako "Sawa-chan" Yamanaka from ''Manga/KOn'' tries hard to be a mature adult around her coworkers and most of her students at school, but when she's alone with the Light Music Club her more immature side comes out. There are quite a few jokes about her [[OldMaid getting upset about her age and not having a love life]], and she gets way too excited about shoving the girls into [[CosplayOtakuGirl costumes she made]].
* ''Manga/GreatTeacherOnizuka'': Onizuka spends more time goofing off with his students and even cutting class with them than he does actually ''teaching''. Despite being overly familiar with them, it doesn't stop him from being a PapaWolf when it comes to his students.

%%* Lou's mom in the French comic book ''ComicBook/{{Lou}}'' In addition to being a video game addict, she generally tends to behave in a more immature way than her 12-year old daughter.
* Grandpa from ''ComicBook/TheBeano'' acts like a child and plays with children but as his name suggests is elderly (although he is never shown to have Grandchildren) and also has an even older dad who used to beat him with a slipper if he misbehaved.

* Yukari Tanizaki from ''Manga/AzumangaDaioh'' could be considered to embody this trope, as she's not much more mature than her students, although she is still treated by her students with respect due to being a teacher (by everyone except [[JerkAss Tomo]]). A respect she abuses without shame.

%%* Ryuuji's mother Yasuko from ''LightNovel/{{Toradora}}'' refers to herself as "Yacchan", and makes childish requests like wanting her name written in ketchup on her omelettes.

* ''LightNovel/DragonCrisis'': Eriko is unable to cook and irresponsible, leaving her younger cousin Ryuuji to be the grown-up one.

Also compare PranksterParent.

* Sawako "Sawa-chan" Yamanaka from ''Manga/KOn'' tries hard to be a mature adult around her coworkers and most of her students at school, but when she's alone with the Light Music Club her more immature side comes out. There are quite a few jokes about her [[ChristmasCake getting upset about her age and not having a love life]], and she gets way too excited about shoving the girls into [[CosplayOtakuGirl costumes she made]].
