->''"Then she puts her head upon your shoulder\\
Says she'll marry you when she gets older"''
-->-- '''Peter Cetera''', "Daddy's Girl"

Children have a bit of a strange understanding in regards to sexual relationships between adults. If you don't know about the intricacies of all that kind of stuff, it just seems like the husband-wife relationship is between two people who love each other a lot. Never mind what ''kind'' of love it is. Obviously, since we're talking about little kids here, the effect is usually sweet and endearing rather than creepy.

This trope is the observation of that childhood fantasy, usually but not always made in reflection on past events, as from an adult (or at least teenage) woman's perspective. Usually the character in question looks back on this attitude and laughs -- a boatload of {{Squick}} and concern elicited from viewers if they [[UnluckyChildhoodFriend still have this attitude]] and [[MyGodYouAreSerious mean every]] [[BigBrotherAttraction word of it]].

Bear in mind that a lot of the time fans take things a little too literally. The usage of this trope is more common in Japanese-themed works than in Western ones, although it does appear in the West from time to time.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* ''AngelSanctuary'''s Setsuna and his sister Sara. Carried a bit further [[BrotherSisterIncest because they actually got together]].
* ''CodeGeass'': Euphemia and Nunally talk about how they fought over who would marry their brother Lelouch when they were little girls and laugh about it. Incidentally, in the entire series, those two are the only characters Lelouch explicitly admitted loving... though in regards to the "incident" itself, by the next day both Euphemia and Nunnally had basically forgotten about it and thought Lelouch sitting up worrying who to pick was very amusing.
** Incidentally, since this is the royal family we're talking about, it's not unlikely that such a marriage could actually be expected to happen.
** A flashback Shirley has about her father Joseph also sees her saying that she'll marry him when she grows up, which leads to a good-natured lecture on how Shirley will eventually meet someone she loves differently from him. She was a toddler at the time, so it's all innocent. Of course, she's reflecting on this after learning that [[spoiler:the boy she "loves differently" is the [[WellIntentionedExtremist terrorist]] who unknowingly killed her father with a [[BuriedAlive weaponized mudslide]].]]
* ''Anime/GuiltyCrown'''s Mana Ouma. This, of course, quickly gets into squicky territory when she's driven mad by an alien virus and attempts to rape her own little brother...
* ''Anime/ParanoiaAgent'': One flashback shows how a young daughter told her dad that she wanted to marry him when she grew up. Incidentally, when this girl became a teenager, [[spoiler:[[PervertDad this father would install hidden cameras in her room so he can watch her undress]].]]
** What makes the whole thing even more crazy and horrible [[spoiler:is how the man is no twisted monster, but genuinely loves his daughter and wants best for her, and finds his more physical feelings just as repulsive as anybody else, yet can't entirely resist them. Their phone conversation after she finds out is one of the most messed up, heartwrenching things in the whole messed up, heartwrenching series.]]
* As a child, Yuna Akashi in ''MahouSenseiNegima'' once told her mother that she wanted to marry her daddy when she grew up. Her mother later died, and she's been looking after the household chores for her dad ever since. She has outright stated that she probably ''wouldn't'' mind deep-kissing [[http://www.mangafox.com/manga/mahou_sensei_negima/v28/c253/11.html her father]] Naturally, this admission elicits a {{squick}}ed NoJustNoReaction from Ako. She even carries a picture of her kissing her father around [[VictoriasSecretCompartment in her cleavage]], ''even while trapped in an AlternateUniverse for several weeks''.
* In ''Manga/AishiteruzeBaby'', Yuzuyu declares that she is going to marry Kippei when she grows up (a variation in that Kippei is an older cousin that was [[PromotionToParent assigned to be her caretaker]]).
* In ''Papa To Kiss In The Dark'' the main character Mira says when he was a kid that his dream was to marry his 'Papa' [[spoiler:who ends up being Mira's uncle Kyousuke]].
* In ''GirlsSaurus'', Shingo's little sister wants to live as a married couple with him. They already share the same surname, after all, they'd just have to move far away and keep up the charade.
* During a quick flashback splash page in ''GreatTeacherOnizuka'', class 3-4's resident troublemaker Miyabi remembers a moment where she declared a wish to marry her father.
* A more serious version of this happens in ''Manga/{{Chobits}}'' when [[spoiler:Freya, a robot, decides that her "father" (the man who built her) is her "one special person", and decides to have her memory erased rather than deal with her feelings]].
* Liz in ''KamenNoMaidGuy'' hates large-breasted women because, as a child, she wanted to marry her older brother, who humored her until she [[ACupAngst turned out to be flat chested]].
* This is treated as a central plot point in ''KagihimeMonogatari'': Kiraha wants to love her brother...in that way. However, she recognizes the repugnance of this desire and nearly allows a villain to take her story simply because it would remove her memories of this. The other main characters are naturally a wee bit bothered to discover Kiraha is a ClingyJealousGirl instead of a clingy jealous sister.
* In ''PrincessPrincess'', Yuujirou's family comes to visit while the princesses have to perform. Because his toddler half-brother barely knows Yuujirou and is surprised to see him in girls' clothing, he's initially terrified by him, but accepts Yuujirou at the end by calling him 'Sister'. He then announces his intention to marry 'Sister', which everyone finds awkwardly funny and cute.
** Tooru's teenage cousin Sayaka has a massive crush on him, which is actually encouraged by her parents, who want them to marry. [[HoYay Tooru's friend has to step in to discourage her.]]
* In ''Franchise/SailorMoon'', especially in the [[Manga/SailorMoon manga]] second arc, [[KidFromTheFuture Chibiusa]] is (sort of) in love with her father, Mamoru, or more specifically his past self, who she seems to regard as a different person, up to the point where she brainwashes him as Black Lady, an aged-up evil version of herself, and remains with the Black Moon simply because this way she will have Mamoru to herself forever. She's mentally only 8 years old at the time and seems to get over these feelings later, especially when she meets Helios and develops a RomanticTwoGirlFriendship with Hotaru, suggesting this is the childish variant rather than an actual incestuous crush.
* The entire premise of the ''LightNovel/SisterPrincess'' series. More explanation: An UnluckyEveryDude finds out he's related to [[UnwantedHarem 12 different sisters]] that are quite young and all wanting to marry him.
* In ''Manga/HayateTheCombatButler'', there's the case of Izumi's dad. He doesn't approve of her liking Hayate, [[http://www.mangafox.com/manga/hayate_the_combat_butler/c171/6.html because he took his little girl's words too seriously, it seems]].
** The same seems to be able to be said about Hayate saying this to [[spoiler:Athena, with her acting ''both'' the mother and the crush]].
** Wataru also made the same declaration to his mom when he was about Izumi's age. He grew out of it rather quickly, mostly thanks to ParentalAbandonment.
** And given how Hayate's looks are shared between Nagi's mother ''and'' father, her crush on him falls into this trope just as well.
** And using the 'child-not-understanding-what-marriage-is' side of the issue, Nagi 'marries' Isumi in one of the title pages. This is another that seems to have fallen to the wayside with age.
* A variation occurs in the manga of ''{{X 1999}}'' when a flashback shows Kamui announce to Kotori that he will become her bride when they grow up. Meanwhile, Kotori's actual brother Fuma thinks to himself that [[LampshadeHanging he's pretty sure it doesn't work like that]].
* ''Boku Wa Imouto Ni Koi O Suru'' (''I'm In Love With My Little Sister'') has a flashback scene where young Yori makes a ring of flowers for his twin sister Iku. The parents call it a lovely crown, but he insists that it is a wedding wreath and that he will marry Iku one day. The parents think it's cute and simply smile. This being ExactlyWhatItSaysOnTheTin when they're older the siblings sneak into the church where their parents were married and exchange rings which is as close as they can get to fulfilling their childhood promise to marry each other.
* The OAV adaptation of the bishoujo game ''Ko-ko-ro...'' plays host to a fairly squick-filled and near-literal example of this trope; Asuka Kuonji, [[BrotherSisterIncest deeply in love with her brother, Souji, and who regularly initiates sex with him]], becomes upset when Souji begins a relationship with his teacher, Mizuki. Fearing losing Souji both physically and emotionally, Asuka nudges him into revisiting the traumatic event that numbed him to the world around him and precipitated the start of their incestuous relationship, so that she can take him back from Mizuki. The plot works, and after Souji has fallen catatonic, Asuka fantasizes about [[spoiler:raping his unresponsive body on top of a church altar, crowing and giggling that she and he are together forever]].
* In ''OreImo'', Kirino always wanted to marry her brother since she was a little girl. [[spoiler: They eventually start dating and hold a fake wedding. They do break up and say they will be normal siblings though it is implied that they are still secretly together at the end of the novel]].
* In episode 7 of ''{{Watamote}}'', the mother finds a home video of Tomoko and Tomoki as a little kids, which the latter sees and is somewhat horrified because of how much more affectionate he was towards his [[{{Otaku}} weird]] sister. In it, he says "When I grow up, I'm gonna marry you, sis!" She's old enough to know at that point that siblings can't marry. Although in the present day, she occasionally tries to invoke BrotherSisterIncest, probably because of trashy video games she's played.
[[/folder]]

[[folder:Comic Books]]
* Used in a joke in Larry Gonick's ''ComicBook/CartoonHistoryOfTheUniverse'', where when describing how Egypt was merciful towards their conquered foes by educating them in Egyptian ways, a son asks his father to marry his sister (since Egyptian Royalty is decided by marriage to the royal woman). The father promptly thinks "You call this mercy?"
[[/folder]]

[[folder:Fan Fiction]]
* An ''Literature/{{Animorphs}}'' story involves [[KissingCousins Rachel and Jake]] falling in love with each other, but acknowledging that it probably can't work out with any sort of permanence. Rachel invokes this trope in her narration. "When you're seven, people think it's cute when you say you want to marry your cousin. When you're seventeen, they call you a redneck."
* In some ''Anime/GirlsUndPanzer'' comics, Maho, who cares more for her younger sister Miho than she lets on, is {{Flanderized}} [[MemeticMolester into being]] [[BrotherSisterIncest in love with Miho]] in some comics, such as [[http://danbooru.donmai.us/posts/1310186 this one]] (beware of canon spoilers).
-->'''Maho''': Together with Mother, I am a member of the Nishizumi school, but Miho... is too kind and too cute.
-->'''Shiho''': ...? Very well, I shall go and watch the semifinal match. That girl [[spoiler:should be informed of her disinheritance]].
-->'''Maho''': ''(excited)'' Does that mean I can marry Miho!?
[[/folder]]

[[folder:Film]]
* ShirleyTemple example: in ''Poor Little Rich Girl'', she played Barbara Barry, daughter of a high-powered soap magnate who was rarely home. She says she wants to marry her dad; it was treated as just something a little kid would say.
* The 2008 film ''{{Film/Fireproof}}'' opens with the following exchange (heavily paraphrased):
-->'''Daughter:''' Can I marry Daddy? \\
'''Mother:''' No, because he's married to me. \\
'''D:''' How about when you stop being married? \\
'''M:''' We won't stop. Marriage lasts forever.
* Inverted in the French musical ''Peau d'Ane'' ("Donkeyskin" in English): A king decides to marry his own grown up daughter; when she is reluctant, he asks a scholar whether that's normal. The scholar answers that it's strange because when asked whom they want to marry when they grow up, little girls always say they want to marry their dad.
* A squicky near-miss occurs in the schlock fantasy movie ''[[CaveDwellers Ator: The Flying Eagle]].'' The titular hero and his sister fall in love with each other and tell their father of their intention to marry. The father then reveals that the hero was an adopted ChosenOne who was sent to live with them for his own safety and he gives the kids his blessing to marry. No one in the entire village seems in any way squicked out by this in spite of the fact that the hero and his adopted sister ''believed'' themselves to be blood related, yet wanted to boink anyway.
* ''Wild Strawberries'' a movie about an old man afraid of well, being old, has a scene where the elderly character visits an elderly friend who reads to him some of her children's keepsakes one of which is a scribbled note from a daughter saying 'when I grow up I want to marry daddy'. The lady makes a comment about how sweet and innocent it was.
* This is brought up, but dismissed, in ''On a Clear Day You Can See Forever''. Todd Pringle points out that, since he is just as much in love with Daisy as Doctor Chabot is, perhaps he (Todd) might make a suitable match for her. When Dr. Chabot points out that Todd is Daisy's brother, Todd responds with, "Only by marriage... she's my step-sister, not my blood-sister."
[[/folder]]

[[folder:Literature]]
* It happens in ''Literature/TheForsyteSaga'', with Irene's son. Admittedly, it's a little weird that he actually says he wants to be her lover, but he's plainly just picked up the word as meaning romance and love and nothing more.
* In ''The Bagthorpe Saga'', Daisy is convinced that since her uncle Mr Bagthorpe is by far the wickedest man she knows, he must be responsible for 'putting the baby in Mummy's tummy'. Her grandma is alarmed and instantly sets the record straight.
* In the book ''For Your Eyes Only'' by Joanne Rocklin, Lucy's mother is depressed because a man she thought was romantically interested in her ends up dating someone else. Lucy's twin younger brothers try to cheer their mother up by joking that they can marry her when they're older.
* In ''The Locked Room'' in ''Literature/TheNewYorkTrilogy'', the narrator reminisces that as a child he'd wanted to marry Fanshawe, so they could always live together.
* In ''Literature/TheSoundAndTheFury'', Quentin tells his father he had sex with Caddie. His father doesn't believe him.
* Partially motivated by her fear of abandonment Ulyssandra from ''Literature/TheNightAngelTrilogy'' proposes to her twenty year old adoptive father who she has a crush on days before her twelfth birthday.
* The younger brother in ''The Scarlet Ibis'' [[spoiler:you know, the one that dies]] tells his older brother that they'll each marry one of their parents. The older brother brushes it off as "stupid things kids say."
* In ''Literature/ToKillAMockingbird'', Atticus tells Scout about some people who were "double first cousins," resulting when "[[DoubleInLawMarriage two sisters married two brothers.]]" This is too much for Scout to wrap her mind around, and the closest she comes is guessing that if she married her brother Jem and their friend Dill married his sister, their children would be double first cousins.
* In ''Literature/TheSecretGarden'', Colin insists that he will wed his cousin Mary when they grow up. He even tries to force her to promise him this. When she laughs and says they can't, he reveals that he thinks it is the only way to keep her from abandoning him someday. Of course marrying a first cousin was (and still is) completely acceptable socially in Britain.
* There is a late dynasty Ancient Egyptian tale in which Pharoah's son and daughter fall in love and want to marry. This being Ancient Egypt their father's only hesitation is over whether it wouldn't be politically wiser to make marriage alliances with other distinguished families.
* The UrsulaKLeGuin short story "The Birthday of the World", from the collection of the same name, has a royal family (actually they're referred to as God) in which the eldest boy and girl siblings marry each other, in the manner of many royal dynasties of the ancient world. Ze, the only daughter, knows she is slated to marry her brother Tazu, but when she is little, she isn't overly pleased about this and expresses a desire to instead marry another of her brothers, Omimo.
* In ''ATreeGrowsInBrooklyn'', the other little girls in Francie's neighborhood play a game where they have to whisper the name of the boy they want to marry, and the only person she can think of to say if she's ever asked is her father.
* In the JacquelineWilson book ''Midnight'', Violet remembers how as a little girl she wanted to marry her brother Will. She borders on BigBrotherAttraction when she admits that she still (at age fourteen) harbours dreams of them living together.
* In ''ASongOfIceAndFire'', Cersei and Jaime are an example of this type of relationship that continued well into adulthood, sex and all, [[spoiler:plus Jaime secretly fathering Cersei's children]]. It's mentioned that their mother caught them behaving inappropriately with each other when they were children and moved Jaime's room to the other side of the castle to try and stop it, but obviously this didn't work. Cersei also says that despite knowing this relationship wasn't allowed they comforted each other with the fact that the ruling dynasty also practiced brother-sister marriage, though that backfired horribly when the incest produced "Mad King" Aerys Targaryen, who brought down said dynasty.
* Azaka Kokutou in ''Kara no Kyoukai'' has no qualms about admitting she's in love with her brother, Mikiya, and not as a sibling.
[[/folder]]

[[folder:Live-Action TV]]
* In a deleted scene from the ''Series/{{Firefly}}'' episode "[[CrowningMomentOfFunny Our Mrs. Reynolds]]," River, in one of her more...[[{{Cloudcuckoolander}} whimsical moments]], asks Shepherd Book to [[http://www.youtube.com/watch?v=cdiNqkehGpk marry her to Simon]]. She then [[PillowPregnancy stuffs a pillow under her shirt and pretends to be pregnant]] [[ShotgunWedding to justify it]]. Of course, she ''is'' a Cloudcuckoolander and her brother ''is'' the only one she really connects with [[spoiler:until the end of TheMovie]].
* Among the numerous incest jokes in ''Series/ArrestedDevelopment'' there's a flashback to a magazine cover featuring Buster and his mother Lucile at a dancing competition (I think) with the headline "Why I want to marry my mother".
** Lindsey, upon learning she's adopted, tells her mother she plans to marry Michael. He turns her down not because they grew up together and are like brother and sister, but because he doesn't like older women (though raised as twins, she's actually three years his senior).
*** That may have less to do with her being older and more of him avoiding getting together with his adopted sister.
**** And even more to do with him avoiding getting together with ''Lindsay specifically''.
* A ''Series/MysteryScienceTheater3000'' host segment finds Crow asking Mike for Servo's hand in marriage. Probably the least weird example, considering Servo and Crow are both ''robots''.
* ''MisterRogersNeighborhood'' once featured Fred singing a song about a little boy asking to marry his mother, who in turn makes an effort to explain their relationship.
* In one of the later seasons of ''StepByStep'', Lily informs her father Frank that she's gay because she loves her mother Carol. He gives her a somewhat simplistic explanation of the difference between familial and romantic love and asks her if she wants to marry her mother. She tells him that she doesn't. Because she would rather marry him.
* In one episode of ''HomeImprovement'', Mark, who was about seven at the time, refers to his mom as his "woman":
-->'''Mark''': I have a woman - Mommy.
-->'''Randy''': Your mommy can't be your woman, doofus.
-->'''Tim''': [[DeadpanSnarker A lot of men pay a psychiatrist a lot of money to figure that one out.]]
* In the show ''BrothersAndSisters'' Kitty mentions such a plan. During their childhood, she would pretend to marry her brother Kevin, and they would then be immediately the parents of five children just like their parents. Not quite an example since they were only playing.
* PlayedWith in some Taiwanese dramas. Fortunately [[NotBloodSiblings one side is an adopted child, so the two are not related in any way.]]
* ''Series/TheBorgias'': A fourteen-year-old Lucrezia tells her brother that she'll never love a husband as she loves him. The siblings then find love interests with [[DoppelgangerDating eerie similarities to one another]].
* In an episode of ''Series/{{Mongrels}}'', Nelson asks his father for his sister's paw in marriage. Dad's response: "I think I'm going to be sick!"
[[/folder]]

[[folder:Music]]
* Combined with DualMeaningChorus in Steve Wariner's "[[http://www.cowboylyrics.com/lyrics/wariner-steve/im-already-taken-2921.html I'm Already Taken]]". In the first two verses, the narrator tries to ask out a little blonde-haired girl and gets the title response. By the third verse, she's now the mother of their boy, who asks innocently, "mommy, will you marry me?"
* Adam Sandler sang a song on Saturday Night Live where he (as a child) plans to 'go out' with his mother. In the second verse, he's entered school and wants to go out with his gym teacher. By the third verse, he's grown up and decides he'd like to try for his mother again.
[[/folder]]

[[folder: Mythology and Religion]]
* In Literature/TheBible, King David's son Amnon lusts after his sister Tamar, and eventually [[RapeAsDrama rapes her]]. In that society, being an unmarried non-virgin generally meant being considered DefiledForever, even for princesses. Tamar pleads with Amnon to marry her and "take away her shame," saying that their father would allow it, but Amnon pushes her aside, [[ImAManICantHelpIt blaming her for his actions]]. It bites Amnon BADLY in the ass later -- as Tamar's ''other'' older brother [[KnightTemplarBigBrother Absalom]] soon learns about this and "recovers" Tamar's dignity via murdering him.
[[/folder]]

[[folder:Newspaper Comics]]
* ''ComicStrip/TheFamilyCircus'' had a comic where one of the little boys said something like, "When I grow taller than Mommy, I'm gonna marry her!"
[[/folder]]

[[folder:Video Games]]
* In ''VideoGame/TheLegendOfDragoon'', "Oh, my dear daughter, I miss those days when you used to say, "I'll marry you, papa.""
* In ''[[VideoGame/FireEmblemElibe Fire Emblem: Blazing Sword]]'', this shows up with Priscilla and her long lost brother Raymond, [[ThatManIsDead now known as]] Raven. The ambiguous context of their support conversation makes it unclear whether she is just observing their ChildhoodMarriagePromise or actually expecting Raven to deliver on it. Considering [[BrotherSisterIncest/FireEmblem the franchise]], it's probably the latter.
* Comes up in both ''VideoGame/{{Persona 3}}'' and ''[[VideoGame/{{Persona 4}} 4]]''. In the former, Maiko, a girl that the Main Character can Social Link with will declare her intent to marry the protagonist if he maxes her out (in the ExpansionPack her father will accuse you of pulling WifeHusbandry on purpose). In the latter, the protagonist's seven-year-old [[ValuesDissonance cousin]] will state how she wishes to marry him at the end of the game before he goes back to the city, with her father laughing it off but also not-so subtly stating that he's against such a union (Unless the player also managed to max ''his'' social link, in which case her father's objection is that she's too ''young''. He has no problem with them getting married when she's an adult).
[[/folder]]

[[folder:Visual Novels]]
* ''Hatsukoi'' the [[DevelopmentHell half translated visual novel]] Anzu fills out a marriage license and has her brother sign it when they're kids. This is the start of her route when he finds it and realizes she's treasured it for years.
* Akiha in {{Tsukihime}} would very much like to marry her brother, [[spoiler:the adopted one. In her own route, he reciprocates her feelings, while the blood-related one seems to very much want to marry her, or at least has plenty of subtext to that effect. Unfortunately he's some kind of killer demon vampire thing, and also a complete lunatic, and she makes it very clear that she does ''not'' return his feelings.]]
[[/folder]]

[[folder:Western Animation]]
* ''MuppetBabies'': For some reason, HalfIdenticalTwins Scooter and Skeeter played the king and queen in the "Literature/SleepingBeauty" FairyTale in 2 different episodes -- one when Rowlf lost his voice, and one when Piggy had chicken pox.
[[/folder]]

[[folder:Other]]
* There's a joke in which a young boy announces to his father that when he grows up, he wants to marry Grandma. The father, aghast, replies, "You can't marry my mother!", to which the boy asks, "Then why did ''you'' marry ''my'' mother?"
* The well-mannered and charming boy in [[http://notalwaysright.com/a-polite-snack/24724 this]] Website/NotAlwaysRight story takes his mother on dates, apparently to practice his etiquette.
* A joke in Readers Disgest has a young boy ask if he can marry his mother than his sister. When told he can't marry a family member, he says: "You mean I have to marry a total stranger."
