It's a Long Story

""Let me explain. [Beat] No, there is too much. Let me sum up.""

- Inigo Montoya, The Princess Bride

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 / 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 Noodle Incident.

Compare It Makes Sense in Context where this trope is used but not invoked.

Anime and Manga

 * Kanon Ayu tells Yuuichi several times that the reason she's stole Taiyaki is a really long story. He keeps pestering her about it until she gives up and tells him I was hungry.

Comic Books

 * Subverted in The Adventures of Tintin: in Land of Black Gold, 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, Breaking the Fourth Wall to tell the reader "you'll never know!"
 * In the introduction of Empowered, why the lily-white Ninjette has a Japanese name.

 * In Kyon: Big Damn Hero after Kyon returns to the clubroom with a little cut in the head, a faint line of blood trickling down one cheek:

""So..." I said. "What's all this, then?" "It's a very, very long story," Rachel said stiffly. "I'm immortal," I said."

 * Near the beginning of the German movie Im Juli, Daniel attempts to use this as an excuse not to tell the guy he's hitchhiking what happened. The guy then points out they're going to be in a very long car trip anyway, so he might as well start. Then we go to the actual plot of the movie.
 * Played uncomfortably straight in the appropriately-titled Paulie as he is talking to the janitor.

"Guinan: Emotions? Geordi: I'll explain later."
 * From The Wicker Man, "Do sit down, Sergeant. Shocks are so much better absorbed with the knees bent."
 * Awesomely spoofed in The Muppet Movie 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.
 * In Star Trek Generations, Geordi and Data go to Ten Forward after the former installs the emotion chip in the latter. Data tries Guinan's latest syntheholic beverage and makes a face. She asks him what he thinks of it, and he says he's not sure because he doesn't recognize the emotion.

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?

Western Animation

 * In the 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. When he reveals himself, the others naturally ask what happened and Hudson responds, "It's a long story and one best told over a cup of hot tea" after which they go back to the Clocktower for that tea.
 * Justice League: In "Hereafter", 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 giant cockroaches with Heel Face Turn Vandal Savage 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.
 * In one Winnie the Pooh animated 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 The Powerpuff Girls 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 Rashomon Style but leave just before revealing what was so funny. While it is shown that it is because the Mayor has no clothes on, that means the girls must have returned him to his office naked.

 * In one Danger Mouse 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.: "I'll explain later, Penfold!"
 * This is Yang's last line in the "Yellow" Trailer for RWBY.
