->''"Let me 'splain. ''[beat]'' No, there is too much. Let me sum up."''
-->-- '''Inigo Montoya''', ''Film/ThePrincessBride''

This is a phrase typically used when a character has finished an adventure isolated from the others. Since it is redundant to have him/her explain the events we just saw ourselves, the typical move to have the character answer the others' questions of what happened is with, "It's a long story" with the assumption that he tells it to them later, off-screen.

A variation can be used when the writers need to create a sense of mystery or suspicion about the recent off-screen past of a character. He will reappear or be found/rescued and when questioned by his compatriots will use this line and refuse to elaborate until the court-martial. "It's complicated" works the same way when it's used like this.

Occasionally {{subverted|Trope}} / parodied when one character says this in response to being questioned as to what is going on, only for ''another'' character involved to sum everything up in one sentence, thus proving that it's not actually that long at all.

Another subversion is for the person on the receiving end of the story to say "I have time."

This phrase can also be used as a substitute for the explanation of a NoodleIncident.

Compare ItMakesSenseInContext where this trope is used but not invoked, or ToMakeALongStoryShort, where the events are quickly recapped.

When she's preempted in the ski trip episode, she becomes upset since [[MediumAwareness it's pretty much the only thing she gets to do in each episode]].

[[folder:Comic Books]]
* Subverted in ''Franchise/TheAdventuresOfTintin'': in ''Recap/TintinLandOfBlackGold'', Haddock meets Tintin at the end, and is very adamant in his repeated attempts to explain what happened to him offscreen ("It's quite simple - and, at the same time, rather complicated..."), only to be interrupted every time. Eventually, he gives up, BreakingTheFourthWall to tell the reader "you'll never know!"

[[folder:Fan Works]]
* ''Fanfic/ACrownOfStars'': In chapter 27 [[spoiler:Hikari and Touji]] meet Asuka and Shinji again.

Rayana prefaced her explanation with "It is a long story. Short version for now."
* In ''Fanfic/KyonBigDamnHero'' after Kyon returns to the clubroom with a little cut in the head, a faint line of blood trickling down one cheek:

* Played uncomfortably straight in the [[PollyWantsAMicrophone appropriately-titled]] ''Film/{{Paulie}}'' as he is talking to the janitor.

'''Geordi:''' I'll explain later.

[[folder:Live-Action TV]]
* ''Series/BuffyTheVampireSlayer'':
** Spoofed (what else?):
--->'''Willow:''' Oz is a werewolf.\\
'''Buffy:''' It's a long story.\\
'''Oz:''' I got bit.\\
'''Buffy:''' Apparently not that long.
** And later in the same season:
--->'''Xander:''' Oh God, what'd you do to each other?\\
'''Buffy:''' Long story.\\
'''Cordelia:''' Got hunted.\\
'''Buffy:''' Apparently not that long.
** And then next season on ''Series/{{Angel}}''. (Yes, all three episodes are by the same writer too.)
--->'''Angel:''' It's complicated how this all happened, Buffy, you know? It's kind of a long story.\\
'''Buffy:''' Your new sidekick had a vision, I was in it, you came to Sunnydale?\\

** [[RunningGag And then]] during Buffy's final season.
--->'''Giles:''' I told you my concerns when you recklessly chose to remove the chip from his head.\\

** {{Inverted|Trope}} in "The Puppet Show".
--->'''Buffy:''' [[CreepyDoll [Dummies] give me]] [[TotallyRadical the wig]]. Ever since I was little.\\
'''Willow:''' What happened?\\
'''Buffy:''' I saw a dummy. It gave me the wig. There... really wasn't a story there.
* ''Series/DoctorWho''
** "I'll explain later" is a RunningGag in the spoof episode "[[Recap/DoctorWhoTheCurseOfFatalDeath The Curse of Fatal Death]]". The early Doctors would use this back when they had more companions, as there was no point explaining something that the audience had already seen, but the companion hadn't because they had been TrappedByMountainLions.
** "[[Recap/DoctorWhoS31E4TheTimeOfAngels The Time of Angels]]": The Doctor about his TimeTravelRomance with River Song: "It's a long story and I don't know most of it."
** In "[[Recap/DoctorWhoS31E13TheBigBang The Big Bang]]", Amy says this to her younger self, who's just opened the Pandorica to find her adult self inside. Adult Amy then sees a timeline on the museum wall showing she's been stuck inside the Pandorica for almost 2000 years, and quips that the story is a lot longer than she thought.
** In "[[Recap/DoctorWho2011CSTheDoctorTheWidowAndTheWardrobe The Doctor, the Widow and the Wardrobe]]", Madge Arwell tells her son to let dad know she's found a spaceman in a field (the Doctor) but he's injured and can't get his helmet off, so she has to take him to find a police telephone box. When dad asks where mum is, her son wisely replies, "Out."
** In "The Crimson Horror", the Doctor only shows up halfway through the adventure (which is told from the view of the Paternoster Gang). He gives this trope, then adds, "I'll keep it short." Cue HowWeGotHere [[RetrauxFlashback kinetoscope movie]].
** "[[Recap/DoctorWhoS34E9Flatline Flatline]]": Clara responds with this trope after her boyfriend Danny [[KindaBusyHere hears her]] do a SuperWindowJump after she's told him [[BlatantLies she's not doing any more adventures with the Doctor]], who notes sarcastically: "And what long story are you going to tell Danny, huh? Or haven't you made it up yet?"
** "Long story" is a {{catchphrase}} used by the polar scientists in the 2014 Christmas special "[[Recap/DoctorWho2014CSLastChristmas Last Christmas]]" for what the lab is studying and how any of them got there. The Doctor and Clara use it as well. PlayedForDrama as [[spoiler:these are all details that they ''can't'' provide because the lab doesn't exist. They're all trapped in a DyingDream.]]
* Played with somewhat in ''Series/{{Eureka}}'' where Sheriff Carter is stuck in a time-loop, but every time the loop resets the energy effect injures him. At first it's minor, but after one of the later resets he comes out of his bathroom covered in cuts and scratches and tells his daughter it's a long story and he'll explain later.
* ''Series/{{Farscape}}'':
-->'''Chiana:''' What happened to you guys? Why... why didn't you call in?\\
'''D'Argo:''' Well, the restaurant, it, uh, sort of burned down - I don't want to talk about it, it's a long story.
* The scene in the ''Series/{{Firefly}}'' episode "Heart of Gold" where Nandi kisses Mal, doubling as a CallBack to "Our Mrs. Reynolds":
-->''[short kiss]''\\
'''Nandi:''' What is it?\\
'''Mal:''' Just waitin' to see if I pass out. Long story.
* In ''Series/TheFreshPrinceOfBelAir'', Will's "family" spend the evening with an associate who indulges in unending tedious anecdotes, boring them all. So when Will explains that his recent hijinks are "a long story" they just decide not to probe him on it.
* In an episode of ''Series/GreysAnatomy'', Arizona and Mark hem and haw about why they're with Callie on her ob/gyn visit, until:
-->'''Callie:''' ''[points to Arizona]'' Lesbian lover. ''[points to Mark]'' Baby daddy.\\
'''Dr. Fields:''' Aaand everyone's a little wigged out.
* Subverted in ''Series/HappyEndings''; Max puts his typical spin on this trope.
-->'''Max:''' Dude, we can do that all for no money at all. Welcome to Max World, TM, circle r.\\
'''Brad:''' Really? Wait. You trademarked and registered Max World?\\
'''Max:''' It's kind of a long, drawn-out complicated story with a bunch of different parts. Basically, I didn't. Let's go.
* On the ''Series/{{Heroes}}'' series finale, Peter rescues Sylar from a nightmare prison inside Sylar's head. When Parkman, who had put Sylar in the prison, demanded how they escaped, the two of them curtly reply that it's a long story.
* Sometimes, an episode of ''Series/OurMissBrooks'' will end with Miss Brooks returning home in the evening, to discuss the events of the day with her landlady, [[CoolOldLady Mrs. Davis]].
* Functional equivalent: In ''Series/StarTrekDeepSpaceNine'', Dr. Julian Bashir awakens from a coma (in which he has had a vivid dream about his crewmates and battling through the station to save his own life) with the words "You will never believe where I've been." ''[=DS9=]'' uses it several times, but only rarely plays it straight. Worf in particular uses it more than once--because he doesn't ''like'' talking.
* In the ''Series/StarTrekEnterprise'' episodes "Affliction" and "Divergence" Lieutenant Reed keeps getting into awkward conversations due to getting caught running a black op for Section 31 and being thrown in the brig for it. Since everyone is busy dealing with the Klingons, both he and Captain Archer have no time to explain why he's in the brig to anyone... except when one of the Klingons who attacked the Enterprise gets tossed into the cell next to him. When Reed replies to his inquiry on [[WhatAreYouInFor why he's in the brig]] with "That's a long story," the Klingon prisoner in turn replies "Entertain me." Reed then manages to give him a minimal-details summary in one line.
* ''Series/StarTrekVoyager'':
** In the pilot episode, EnsignNewbie Harry Kim wants to know why everyone is snubbing [[BoxedCrook Tom Paris]].
--->'''Paris:''' It's a long story, Harry, and I'm tired of telling it. I'm sure someone around here will tell you before long.
** In "Projections" this line is spoken by the Doctor to Captain Janeway because the [[DreamWithinADream events that have happened are all so convoluted]]. When Janeway does insist on an answer, she quickly loses patience and orders the Doctor thrown in the brig.
** Played straight in "Cold Fire".
--->'''Tanis:''' What would an Ocampa be doing on an alien starship? \\
'''Kes:''' It's a long story. But I'd like to know what an Ocampa is doing on an alien space station. \\
'''Tanis:''' That is also a long story.
** In "Parturition", Janeway summons Tom Paris and Neelix to be briefed on an away mission, only to find them covered in the results of the food fight they've just had in the mess hall.
--->'''Janeway:''' Would anyone care to explain?\\
'''Paris:''' It might be too long to go into right now, Captain.
* Besides being ''{{Series/Forever}}'''s CatchPhrase, Henry says this to Jo when she decides she wants the truth about his strange past.
* ''Series/GameOfThrones'':
** Gendry has been thrown into the dungeons with Lord Davos Seaworth.
--->'''Gendry:''' So how'd you become a lord?\\
'''Davos:''' Oh, that's a long story.\\
'''Gendry:''' ''[glances around at his empty cell]'' [[DeadpanSnarker Better not, then. I'm a bit busy.]]
** In Season 7 when Jon Snow and Tyrion Lannister meet up for the first time since Season One, naturally this trope comes into play, with Tyrion adding, "...and I was drunk for most of it."

* ''Radio/TheHitchhikersGuideToTheGalaxy'', Fit the Eleventh:
-->'''Hurtenflirst:''' Why do those other two chicks we picked up look exactly like you?\\
'''Lintilla:''' It's a long story.\\
'''Hurtenflirst:''' Quick précis then.\\
'''Lintilla:''' ''Because.''\\
'''Hurtenflirst:''' That's ''neat!''

[[folder:Puppet shows]]
* Subverted on ''Series/TheMuppetShow'' after Captain Link is injured on the set of a "Pigs in Space" skit (it's kind of hard to describe...)
-->'''Den Mother:''' What happened to him?\\
'''Kermit:''' It's a long story... Actually, it's a ''short'' story. He did something ''dumb''.
* Awesomely spoofed in ''Film/TheMuppetMovie'' when Fozzie starts to reiterate the whole plot so far to the Electric Mayhem. Kermit decides to save time by letting them read the script.

* ''Toys/{{Bionicle}}'':
-->'''Axonn''':Just so you know... Brutaka's [[IAmLegion his own "we"]] now. Long story."

[[folder:Video Games]]
* Conker says this in the intro to ''VideoGame/ConkersBadFurDay'', when he begins to explain to the viewer how he became a king and who all the strange people surrounding his throne are. The rest of the game takes place during the previous day.
* In ''VideoGame/KingdomHeartsII'':
** When the gang are in Christmastown, SantaClaus asks [[IdiotHero Jack]] "What sort of trouble did you bring ''this'' time?" Sora asks Jack about it, and Jack replies, "[[WesternAnimation/TheNightmareBeforeChristmas It's a long story!]]"
** The same could be said for the entire series' plot in general.
** Played for laughs in the [[Manga/KingdomHeartsII manga adaptation]] when Sora uses his Keyblade to open a barrier and allow himself and his allies to escape.
--->'''[[spoiler:Tron]]:''' What... what did you do?\\
'''Sora:''' It would take too long to explain.
* ''VideoGame/MonkeyIsland2LeChucksRevenge'' [[ColdOpen starts]] with Guybrush hanging above a huge pit holding a rope with left hand and a huge trunk in the right.
-->'''Elaine:''' ''[from another rope]'' How did you get into this mess?\\
'''Guybrush:''' It's kind of a long story.\\
'''Elaine:''' That's OK, I've got time.\\
'''Guybrush:''' Sigh... ''[credits start]''

[[folder:Web Animation]]
* In ''WebAnimation/{{RWBY}}'s'' "Yellow" trailer, Yang Xiao Long says this when Ruby Rose asks her, "What are you doing here?"

[[folder:Web Comics]]
* Served with a bit of LampshadeHanging in [[http://freefall.purrsia.com/ff500/fv00431.htm this]] strip from ''Webcomic/{{Freefall}}'', changing the focus to Sam and Helix while Florence explains how she ultimately arrived at Dr. Thurmad's house.
* In ''Webcomic/SchlockMercenary'', after the battle with diamond beetles on the Princess Tyola:
-->'''Dr Bunnigus:''' Why raid food stores? Why not use our original bodies for mass?\\
'''Schlock:''' You don't want to hear it. It's a long story.\\
'''Dr Bunnigus:''' Try me.\\
'''Schlock:''' Well, after I ripped everybody's heads off and froze them, I ate your bodies so I'd be big enough to take on the beetle-monsters.\\
'''Dr Bunnigus:''' ... Where does this story start being long?\\
'''Schlock:''' Did I say long? I meant disturbing.
* ''Webcomic/CharbyTheVampirate'' sums up Mye's terrifying night with [[http://www.charbythevampirate.com/comic/375/comic_archive chibi drawings]]. It is long indeed, as it started a good [[http://www.charbythevampirate.com/comic/307/comic_archive 75 pages earlier]].
* ''[[Webcomic/RoomiesItsWalkyJoyceAndWalky It's Walky!]]'' does the big setup version [[http://www.itswalky.com/d/20040113.html here:]]
-->'''Rachel:''' Okay, Joe, I think it's time we told you the sad truth Robin has had to face throughout her childhood. It's a long and sordid tale, and every twist and turn will break your heart.\\
'''Agatha:''' Robin's father slept around.
* Subverted in ''Webcomic/{{Homestuck}}'' when Aranea is asked how the [[spoiler:pre-scratch trolls survived the scratch]]. She, as a writer with a somewhat overdramatic flair, claims that the story requires a lot of detail and context to tell properly. Meenah shoves a hand over her mouth and tells the whole story in a few sentences. Aranea is Not Pleased.

[[folder:Web Original]]
* This is Captain Susano's response in ''Script/AHDotComTheSeries'' upon being asked why his [[NoSwastikas Cyborg Robots With Green Blood]] have started acting like Film/TheThreeStooges.
* ''WebVideo/BumReviews'': This is how Chester A. Bum handwaves some of his more... ''esoteric'' claims.
-->'''Chester A. Bum:''' I had no genitalia once! Long story.

* Subverted in ''WesternAnimation/{{Archer}}'':
-->'''Mallory:''' And since when do you carry a switchblade?!\\
'''Archer:''' It's a long story, Mother!\\
''[flashback to Archer noticing the switchblade in a display window]''\\
'''Archer:''' Neat!\\
''[end flashback]''\\
'''Archer:''' Well, not so much long as just not very interesting.
* In one ''WesternAnimation/DangerMouse'' episode, Penfold basically turns his back for a moment and then sees that D.M. has escaped from the trap he was just in, and fixed their car as well. Penfold asks how he did it, and D.M. says, "I'll explain... later, Penfold." Penfold: "But how did you fix the car?" D.M.: [[LampshadeHanging "I'll explain later, Penfold!"]]
* ''WesternAnimation/TheFlintstones'' episode "Happy Housewife", where Wilma stars in a TV show about making husbands happy through cooking, only she's been neglecting Fred. The president of a rival TV station takes this to mind and visits Fred:

'''Fred:''' ''[slow-burn]'' Ya really wanna know? Then sit down, buster, have I got a story to tell you!
* In the ''WesternAnimation/{{Gargoyles}}'' episode "The Price", Hudson escapes from Xanatos' captivity and finds that clan is mourning the destruction of a statue of himself they thought was him in a permanent stone state.

* ''WesternAnimation/JusticeLeague'':
** In "Hereafter", Franchise/{{Superman}} is blasted into the future. The world mourns his loss and the League has to stop supervillain rioting in Metropolis. Meanwhile Superman has a nature hike across a crazy post-apocalyptic landscape, and fights [[BigCreepyCrawlies giant cockroaches]] with HeelFaceTurn Comicbook/VandalSavage as they try to power up a time machine. Superman appears a few days later with a beard, ragged clothes and pops up just in time to take a bullet meant for Batman. What happened to him? "It's a long story." Even better, he starts to try to explain, but it's all: "and then Vandal Savage and I fought some giant cockroaches" and he gives up because everyone's just staring at him. And his...wolfskins and his ''beard''. He left the sword behind, though.
** A lot of Franchise/{{Batman}}'s anecdotes are subtle [[ShoutOut references]] to ''WesternAnimation/BatmanTheAnimatedSeries'' and his [[Franchise/{{Batman}} comic adventures]], truncated with either this or YouDoNotWantToKnow.
* In one ''WesternAnimation/TheNewAdventuresOfWinnieThePooh'' episode, Pooh's friends think he's moving away, so they hold a going-away party for him and see him off. Pooh never intended to move away, but plays along and returns back home after about two seconds. His friends ask him why he's come back so soon. Pooh replies, "It's a long story," probably because he can't think of a good explanation (or for that matter, fully understand it himself as he's a bear of little brain) of how they were mistaken.
* In ''WesternAnimation/ThePowerpuffGirls'' episode "The Bare Facts", the Mayor thanks the girls for saving him from Mojo Jojo but asks why they were laughing at the time. They say it is a long story, while the Mayor has time to listen. The three explain the events in RashomonStyle but leave just before revealing what was so funny. [[NakedPeopleAreFunny While it is shown that it is because the Mayor is naked, that means the girls must have returned him to his office without letting him put his clothes on first]].
* ''Franchise/ScoobyDoo'': In "Decoy for a Dognapper", Velma is groping around for her glasses, which a bat had dropped on Scooby's face. Shaggy retrieves it and gives it to Velma:

* ''WesternAnimation/StarWarsRebels'': At the end of [[Recap/StarWarsRebelsS3E12Warhead "Warhead"]], after having called the rest of the ''Ghost'' crew back early from a training exercise, and a transmission from [[ReverseMole Fulcrum]] congratulating him, Zeb says this when asked what happened.
* In the episode "War Dawn" from ''WesternAnimation/TheTransformers'' the Aerialbots go back in time and meet Optimus Prime nine million years in the past.

* ''WesternAnimation/TheVentureBros'' had this in ''Twenty Years to Midnight'':
-->'''The Grand Galactic Inquisitor:''' Good news, sample subjects of earth! The glorious moment of judgment is upon you!\\

'''The Grand Galactic Inquisitor:''' [[RunningGag Ignore me!]]\\

'''Rusty Venture:''' Long story. Just ignore him.
* {{Subverted}} [[PlayedForLaughs For Laughs]] in ''WesternAnimation/DaveTheBarbarian:'' Fang reveals that she can play the lute, and says that it's a long story. As she tells it, we get a 10-secondish {{Flashback}} of her about to crush a bug, only for it to offer to teach her to play the lute if she spares it. Cutting back to the present, Fang [[LampshadeHanging admits]] that the story actually wasn't very long.
* PlayedForLaughs in ''WesternAnimation/PhineasAndFerb''. In one episode, [[MadScientist Doofenshmirtz]]'s FreudianExcuse is unusually long and complicated, including [[CallBack tying in to backstories from previous episodes]]. At one point he notes that there's a part that he doesn't want to even get into, but short version: he'd been disowned by [[AbusiveParents his family]] and was temporarily [[RaisedByWolves raised by ocelots]].
