-> "''One moooooore thing...''"
-->-- '''Uncle''', ''WesternAnimation/JackieChanAdventures'', having not quite finished the conversation.

Two characters are in a room having a conversation. One of them makes to leave. But as this character reaches the door, he or she turns back to deliver a final line. Often this is some bit of exposition that sets up something later in the episode ("the starboard discombobulator's on the fritz") but that the writer couldn't figure out how to work into the scene's main conversation. Other times, during an argument, it's used to reinforce a TheReasonYouSuckSpeech with what usually equates to [[YouAreBetterThanYouThinkYouAre "The Reason I Don't Suck"]] and/or ArsonMurderAndJaywalking. In some shows there might be several lines of dialog between the two characters as the departing actor tries desperately not to look as though he's loitering in the doorway.

Just to mix things up a little bit, sometimes they'll do it the other way around: the character who remains in the room will call to the character who's leaving just as the latter reaches the door.

This trope is distinctly different from a good old-fashioned exit line, because the line itself isn't dramatic ("You can't fire me! I quit!") and is often in fact something of a non sequitur, which must be eased into with a phrase like "and another thing", "oh yeah", or "by the way."

Sometimes a character actually gets out the door, then comes back in to deliver a line, but this is usually for comedic effect. See DoorFocus.

Not to be confused with ''Literature/AndAnotherThing'', the sixth book in ''Literature/TheHitchhikersGuideToTheGalaxy'' trilogy.

* Manga/{{Alyosha}} leaves the meeting where she tells [=FBI=] Katie Lindberg that she's the infamous assassin Kortik saying [[spoiler: "There are another two Kortiks beside me]].
* In ''LightNovel/{{Bakemonogatari}}'', Senjougahara tells Araragi that she has an idea how to help Hachikuji, but she has one more thing to say before they go:
-->One more thing, Araragi-kun... ''[[GratuitousEnglish I LOVE YOU]]''.

[[folder:Films -- Animation]]
* In ''Disney/{{Cinderella}}'', the WickedStepmother gives the titular heroine a list of chores for her to perform. As Cinderella starts to leave the room, she states "Oh yes, and one more thing... See that [[RightHandCat Lucifer]] [[CatsHateWater gets his]] [[HatesBaths bath]]". Cue OhCrap reaction from Lucifer.
* She isn't leaving, but in ''Disney/TheEmperorsNewGroove'', Yzma finishes up a rant about how stupid and useless [[MinionWithAnFInEvil Kronk]] is with "And another thing! I never liked your spinach puffs! Never!" (This actually [[BerserkButton motivates Kronk to turn against her]].)

[[folder:Films -- Live-Action]]
* Used brilliantly in many of Quentin Tarantino's movies. Uniquely, Tarantino usually uses this trope as a prelude to shit going down.
** Most notably in ''Film/DjangoUnchained"; it is said verbatim by Candie, leading to an entirely unnecessary yet oh-so-rewarding shootout.
** Likewise in ''Film/InglouriousBasterds''. Major Dieter Hellstrom was about to leave, but then decides he'll just have one last drink with the company before he goes. It doesn't end well.
** It's used by the narrator in ''Film/TheHatefulEight'' after the intermission to inform the viewers of a plot point.
* Spoofed in ''Film/AShotInTheDark'' with the help of DoorFocus: Clouseau leaves Dreyfus' office after an argument, the door closes behind him, and we hear "And another thing!" [[spoiler:Since Clouseau doesn't ''know'' it closed, he turns around as he says this, points at Dreyfus -- and thus smashes the frosted glass window in the door. Embarrassed, he leaves without saying whatever that other thing was.]]
* Maggie attempts this in ''Film/TheGreatRace'', but never gets to finish it as Hezekiah drags her from the tent. She does manage to get in a nice air-kick though.
* A CatchPhrase of the Wiseman from ''Film/SuckerPunch''.
* Old Biff to 1955 Biff in ''Film/BackToTheFuturePartII'': "There's one more thing. One day, a kid or a crazy old man who claims to be a scientist is going to come around asking...". This is a callback to an earlier point in the film (though it occurs later chronologically), when 1985A Biff says to Marty: "Oh, and he told me one more thing. He said, "Someday a crazy, wild-eyed scientist,"or a kid may show up asking about that book. "And if that ever happens... ''(pulls out a gun)'' " Funny. I never thought it would be you."
* ''Film/{{Carnage}}'' would end if the visiting couple left the apartment. They're stopped at the front door or in the hallway outside several times by an invitation, an unresolved question, or just an argument. At least once, the husband (who desperately wants to leave) is left waiting with one foot in the elevator.
* Done on the person leaving in ''Film/TheNameOfTheRose''. The Abbot wants to consult the newly-arrived William of Baskerville about a [[LockedRoomMystery suspicious death]], but has been advised against it. Realising the Abbot has something on his mind, William waits till he's leaving the room before asking about the fresh grave outside. Caught off guard, the abbot ends up asking for William's help anyway.

* ''Literature/ASongOfIceAndFire'': Tywin tells Tyrion, "You will not take the whore to court."
* ''Literature/TheMoonstone'':
** [[spoiler:One of the Indians]] visits the offices of a couple barristers merely to form an excuse to ask one final question before leaving.
** In ''Armadale'', Mr Pedgift senior does this all the time.
--->He invariably kept his strongest argument, or his boldest proposal, to the last, and invariably remembered it at the door (after previously taking his leave), as if it was a purely accidental consideration which had that instant occurred to him. Jocular friends, acquainted by previous experience with this form of proceeding, had [[Administrivia/NamingATrope given it the name]] of '[=PedgiftsPostscript=]'.
* Subverted in ''Discworld/MenAtArms''. Vimes, investigating an explosion at the Assassins' Guild, pulls an AndAnotherThing moment to try to get Dr. Cruces, the Guild leader, to admit there was a theft as well. Dr. Cruces, however, doesn't fall for it, and flatly states, "I never said anything was stolen." [[spoiler:It's true, he didn't say anything was stolen, but that doesn't mean that nothing was stolen. The key PlotDevice was stolen.]]
** In fact Vimes expected Cruces to deny anything was stolen - doing so [[spoiler: was what confirmed what was stolen was important.]]
* Gleefully parodied by Isaac Asimov in his SelfInsertFic "Murder at the ABA", when his written self gets up after chatting to a colleague about the murder that occurred the day before:
-->''I wish I could do the dramatic thing. I wish that at the last minute I could remember something for you, some little apparently unimportant event that would break the whole case, but I can't do it. But why should that bother you? I was ten feet away and completely busy with my own signings. I'm not your best witness. Why don't you ask what's-her-name?''

[[folder:Live-Action TV]]
* Perfected by Lieutenant Series/{{Columbo}} as a means of turning the screw on a suspect who is already exasperated by Columbo's [[ObfuscatingStupidity shenanigans]], since an ExasperatedPerp is liable to make a [[JustOneLittleMistake crucial mistake]]. Though this became Columbo's most distinctive character trait, it started as a mistake. During the filming of the ''Series/{{Columbo}}'' pilot, "Prescription Murder", Peter Falk simply forgot to deliver his last line before leaving the set, so he turned around, came back, and said "One more thing..." [[ThrowItIn The take was left in]], and became a defining moment.
* Likewise, Detective Goren from ''Series/LawAndOrderCriminalIntent'', also uses AndAnotherThing in the same way as Columbo did.
* Tywin Lannister from ''Series/GameOfThrones'' ends some meetings with an afterthought. His hostile distaste for Tyrion's whoremonging ends two political conversations with his son, and when Tywin is heading for the door after a one-sided audience with King Joffrey, he feels the need to add a last second pleasantry, so he turns back and utters a condescending "Your Grace".
* The medical version (the "doorknob question") appeared in ''Series/{{House}}'': according to the writers (and presumably their medical consultants), many patients come in for a trivial ailment, and then bring up the "other thing" (probably the serious illness they actually ''want'' treatment for, but which embarrasses them) as they reach for the door knob.
* Detective Flack did this once on ''Series/{{CSINY}}''. When he made to leave, the door gave him a EurekaMoment -- he realised that the victim's door had been locked from the outside, so whoever killed him must have had a key.
* ''Series/StarTrekTheNextGeneration'' often raised this to an art form, with whoever Picard was talking with in the ready room would say that one more thing at the door. And the reverse happens just as often, with Picard adding "one more thing" when whoever is in his ready room at the time is almost out the door, especially in the later seasons. In fact, near the end of the series, it's surprising to see anyone coming out of the ready room without Picard adding a comment.
* Happened on ''Series/TheWestWing'' too many times to count. Often the plot of an episode relied on one or more of these moments.
* Kellerman got a CrowningMomentOfAwesome in his first case on ''Series/HomicideLifeOnTheStreet''. Interviewing a suspected murderer/arsonist, he tells the suspect that they don't have much of a case beyond what he's already explained away, and that it looks like he's free to go. As the man is grabbing his coat, Kellerman asks, "Why'd you kill the dog?" [[spoiler: The man's answer, "I didn't know the dog was there."]]
* Frequently on ''Series/{{NCIS}}'', when Gibbs would visit [[PerkyGoth Abby]] in her forensics lab and she would provide some information. Just as Gibbs is about to leave, Abby then chimes in with, "Wait, there's more," and provide another even more vital clue.
* Done in the third episode of Series/{{Sherlock}}. [[spoiler: Jim Moriarty tells Watson and Holmes that he isn't going to kill them right now, and leaves, apparently taking his unseen sniper with him. Holmes runs to Watson and gets off the explosive jacket he is wearing, and everyone breathes a sigh of relief... until Moriarty walks back in, the [[LaserSight little red dots of death]] return, and he says he's changed his mind and he can't let them leave after all.]]
* In ''Series/{{Torchwood}}'', at the end of Episode 1, Season 2 right before John Hart leaves, he tells Jack [[spoiler: "Oh yeah, I found Grey."]]
* In the ''Series/BabylonFive'' episode "[[Recap/BabylonFiveS01E01MidnightOnTheFiringLine Midnight on the Firing Line]]", Sinclair finishes his conversation with Kosh and turns to go. Only then does Kosh deliver his opinion on the matter at issue:
-->'''Kosh:''' They are alone. They are a dying people. We should let them pass.\\
'''Sinclair:''' Who? The Narn or the Centauri?\\
'''Kosh:''' [[MathematiciansAnswer Yes]].
* ''Series/TheGoldenGirls'', season two, episode 14, "The Actor". Blanche, Rose and Dorothy have just learned the visiting actor they've all been (secretly) dating has been dating each other, [[ReallyGetsAround as well as other women]], and have decided to call him out for it during one of his performances, with Blanche rounding her bit out with:
-->'''Blanche:''' And as God is my witness, I will ''never'' shampoo your hair again!\\
'''Dorothy:''' And another thing -- you'll never ''what''?!
* ''Series/{{Seinfeld}}'':
** In the second part of "The Cadillac", Susan Ross, George's fiance, goes to Elaine's apartment to confront Elaine about what she suspects is an affair between Elaine and George (in reality, George was lying so he could go on a date with Marisa Tomei). Initially, the two of them seem to have cleared everything up, as Elaine gave the same story that George gave Susan (that Elaine was having issues with her boyfriend over his importing/exporting business), which pleases Susan, who then turns to leave. As soon as she gets to the door, however, she asks Elaine what the issue is with the business and, since this part of the lie wasn't explained, the lie begins to unravel.
** When George competes for sympathy points against a survivor of the Andrea Doria, he moves the condo board to tears by going through his lifetime of tragedies as a "short, stocky, slow witted, bald man." After concluding, he throws in:
---> '''George:''' ...Oh, and my fiance died from licking toxic envelopes that I picked out. Thank you for your time."
* ''Series/StarTrekDeepSpaceNine''. In the NoirEpisode "Necessary Evil", Odo does this while interrogating a FemmeFatale, in an obvious ''Series/{{Columbo}}'' homage (although Odo's actually a fan of Creator/MickeySpillane).
* Conversed on ''Series/InTreatment'', where Mia has a tendency to say something important when she's about to leave.
* ''Series/{{Supernatural}}''. Sam Winchester tries this in "Heartache", only to be cut short by the person he's talking to, who is clearly intent on not providing any useful information.
-->'''Sam:''' Just one more question...\\
'''Woman:''' There is always one more question in life, isn't there? That's what I find. ''(ushers them out)''

* ''Theatre/TheWomen'':
-->'''Little Mary''': And another thing, I think this bathroom is perfectly ridiculous!
* ''Theatre/{{Hamilton}}'':
-->'''Burr:''' Hamilton, sit down. "Our client Levi Weeks is innocent, call your first witness." That's all you had to say.\\
'''Hamilton:''' Okay. [{{beat}}] One more thing!

[[folder:Video Games]]
* ''VideoGame/TheLegendOfZeldaPhantomHourglass'' includes a pirate whom you fight on your ship at least twice. Every time you defeat her, she gives one of these lines - most of them quite lame and irrelevant.
* Granin does this in ''VideoGame/MetalGearSolid3''. Snake is leaving, thinking he's done with the drunk scientist, but Granin stops him to give him a key and tells him which way to go.
* At the end of an over half-hour video released in October 2014 that promoted at least fifty things that were to be expected in ''VideoGame/SuperSmashBros for Wii U'', the announcer said, "Time for a special announcement!" as the video was completely black. Then, it fades into a clip showing a model of Mewtwo being rendered, with the video confirming that the [[OlympusMons Legendary]] Franchise/{{Pokemon}} [[TheBusCameBack will finally be returning to the series]] as free DLC in Spring 2014. ''Smash'' fans around the world freaked the Hell out.
* Used in combination with BondOneLiner in ''VideoGame/TeamFortress2'':
-->'''The Engineer, dominating a Heavy:''' And another thing: ''[[PunctuatedForEmphasis You're. Ugly.]]''
* ''[[VideoGame/UnderTale Undertale]]'' has this gem:
-->'''Sans:''' by the way... i was going to say something, then i forgot.

[[folder:Web Comics]]
* In ''Webcomic/TheKamics'' Brunhilda pulls the trick off [[http://www.theduckwebcomics.com/The_KAMics/5420201/ here]].

[[folder:Western Animation]]
* This trope was parodied mercilessly on ''WesternAnimation/SouthPark'' with a scene that ended in ''four'' successive And Another Things.
* ''WesternAnimation/CloneHigh'' did the same in in the premiere, as JFK kept coming back into the bathroom to reiterate the fact that Lincoln and Gandhi weren't invited to his party, and then because "I forgot to wash my hands!"
* Uncle from ''WesternAnimation/JackieChanAdventures'' easily established "One more thing!" as one of his [[CatchPhrase catchphrases]] by the end of his first scene in the series.
** In the French version, this is changed to ''"Je n'ai pas fini!"'' ("I'm not done yet!"), with similar results.
** Especially funny when the "one more thing" was to smack Jackie in the head.
*** In fact, there was one episode in which Tohru actually called him out on this. As a result, the master and the apprentice could no longer do their teamwork, and Tohru was kidnapped. When it happened, Uncle blamed himself while noting his tendency to overrepeat "one more thing" (not without saying "one more thing" before, of course) and ''whacking himself in the head repeatedly''.
** This seems to be something that Uncle picked up as he got older. When he wore the Dog Talisman of immortality in one episode, he regained the vitality and mindset of his youth though his outside appearance remained unchanged. Jade [[OutOfCharacterAlert notices that he hasn't said "And one more thing" for a while]].
* In ''WesternAnimation/{{Daria}},'' Daria Morgendorffer's mother and her principal don't get along very well. When they end up in a tent alone together in one of the ClassTrip episodes, it looks like they'll be at each other's throats immediately, but the show subverts expectations by showing them to have...a pleasant conversation. An ''awkward'' conversation, to be sure, but a pleasant one. Helen ends up (unintentionally) admitting her age and her insecurity about it, and that doesn't escape Ms. Li's notice when, moments later, the scene devolves into a shouting match. As Helen is turning to leave, Ms. Li stops her to say, "And by the way, ''you look '''fifty'''''." Helen's mouth turns into an "O" of shock.
* There was a WesternAnimation/BugsBunny cartoon where Bugs got a job as an organ grinder's monkey, managing to anger a gorilla in the process. When Bugs is done [[KarmicTrickster telling the gorilla off]], he adds "And another thing...stop breathing on my cup!"
** Bob Clampett's ''Tortoise Wins By A Hare'' (1943) has Bugs disguised as an old timer trying to learn Cecil Turtle's method of beating the hare. His final line (indicating he knew it was Bugs all along): "Another thing...rabbits aren't very bright, either!"
* In the ''WesternAnimation/{{Gargoyles}}'' episode "Turf", Angela has to tell the Trio off. While they were showing off and generally acting like idiots, the bad guys got away. She tells them that they have to focus on catching the bad guys, she is not a prize to be won, "And one more thing...STOP CALLING ME ANGIE!"
* On ''WesternAnimation/TheSimpsons'', Nelson engages in PerpSweating when he suspects Bart and Lisa of killing Martin. The whole thing is a spoof of ''Series/{{Columbo}}'', complete with Nelson engaging in an AndAnotherThing.
* In one of Creator/TexAvery's George and Junior cartoons, George goes into a cave to lure out a chicken and instructs Junior to hit the first thing that comes out. He then turns around to say "And another thing"... and that's when Junior clobbers him.
* During one episode of ''WesternAnimation/{{Metalocalypse}}'', Dethklok walks in on a sadistic fashion designer [[spoiler: [[GenuineHumanHide skinning models alive]].]] They can only stand there and scream. Except for Nathan, who makes sure to say:
-->'''Nathan Explosion''': Oh, my god, what a horri- you're fired, by the way!
* In the ''WesternAnimation/FamilyGuy'' ''Film/ReturnOfTheJedi'' spoof, Yoda continues to give dying gasps saying "Luke..." before sharing information before he finally dies.
* In the ''WesternAnimation/StevenUniverse'' episode "When It Rains", the Crystal Gems are heading out, leaving Steven to hold down the fort, when Garnet remembers something important:
-->'''Garnet:''' Oh! Steven, there's one more thing I have to mention!\\
'''Steven:''' What is it?\\
'''Garnet:''' ''[makes HeartSymbol with her hands]'' [[SugarWiki/HeartwarmingMoments I love you!]] 'Bye!
[[SelfDemonstratingArticle Oh, and one more thing...]]
[[folder:Real Life]]
* This is a common strategy for stage presentations, to the point where it's become expected. The announcement will usually be the biggest one of the event. Steve Jobs was fond of this, as is Nintendo -- ''VideoGame/TheLegendOfZeldaTwilightPrincess'' was famously announced this way.
* Similarly, politicians often leave the "big" reveals until their end of speeches; for example, the 2011 UK budget left a cut in fuel duty until the very end of the budget. The end result is a noticeable "oh snap" moment among observers, including there at the speech and elsewhere, watching live. It also makes for prettier news coverage.
* This is known as a "[[http://www.webmd.com/fitness-exercise/features/are-you-too-embarrassed-to-ask-your-doctor doorknob moment]]", where the very act of leaving prompts one party in the about-to-be-terminated conversation to offer information that had not come up, though it is more often the person who is not walking out the door that offers up new information.
