->'''Edward:''' ''You're the fairest maid I've ever met,''\\
''You were made--''\\
'''Giselle:''' ''To finish your [[LetsDuet duet]]!''

%% One page quote is sufficient. Place additional entries on the Quotes tab.

We've all heard it before... literally. Some people know each other so well, they finish each other's sentences. The effect is usually a demonstration of how close the two people are-- they're so familiar with one another, they even ''think'' alike.

Generally comes in two forms-- the single line and the complex dialogue. The single line goes something like,
-->'''Bob''': Where are my damn--\\
'''Alice:''' Glasses? Check your head.

The complex dialogue is more elaborate:
-->'''Bob:''' Where are my damn--\\
'''Alice:''' Glasses? Did you check your--\\
'''Bob:''' Yes, my head is always the first place I look, thank you very much.\\
'''Alice:''' Mom was right, I should never have married--\\
'''Bob:''' "A forgetful lout like you," yeah, I know.

Closeness and familiarity aren't the only reason for this trope. Others include:

* [[CatchphraseInterruptus Lampshading]] a CatchPhrase or ArcWords
-->'''Alice:''' This looks like a job for--\\
'''Bob:''' Someone else.
* Mocking someone for their clichéd ideas:
-->'''Alice:''' Superman will--\\
'''Bob:''' Rescue you? I think not.
* LastSecondWordSwap ([[SubvertedRhymeEveryOccasion especially when]] the audience was expecting it to [[RhymesOnADime rhyme]]):
-->'''Alice:''' That sexy young farmer has an enormous--\\
'''Bob:''' Potato gun!
* Making a quick gag by having the finished sentence be [[AreYouPonderingWhatImPondering nothing at all]] like what the first person was going to say.
-->'''Alice:''' Maybe we should--\\
'''Bob:''' Tie a banana on its nose and conga under its legs!\\
'''Alice:''' I was going to say call the police.
* Showing that two people who don't know each other are thinking the same thing.
-->'''Alice:''' Maybe we should--\\
'''Bob:''' Cross the streams--\\
'''Alice:''' And reverse the polarity--\\
'''Bob:''' To raise the deflector shields! [[GeekyTurnOn Marry me]].
* And more!

This trait is often found in CreepyTwins, SingleMindedTwins, and SickeninglySweethearts, but hardly restricted to them-- lovers, parents, siblings, friends, co-workers, enemies, even strangers can do this. And while we're at it, it doesn't have to be only two-- loads of people can get in on the act, although it might start to stretch credibility. Also present as a way of showing that two characters are telepathic or are parts of a HiveMind.

If the characters are built around this trope, it's a sign of a big problem when they ''don't'' finish each other's sentences. If one character is a psychic, expect the other to shout something like, "[[PsychicLink Get out of my head!]]" Or even if they aren't psychic, if it happens often enough.

A similar effect is having characters FinishDialogueInUnison. TwoScenesOneDialogue and DistantDuet have characters finishing each other's sentences without even being in the same scene. Compare StrangeMindsThinkAlike, CatchphraseInterruptus, SpeakInUnison.



[[folder:Anime and Manga]]
* The twins Hikaru and Kaoru in ''OuranHighSchoolHostClub'' do this sometimes. In Haruhi's ''Literature/AliceInWonderland'' dream, they played the Cheshire Cat and appeared alternatingly from different sides, finishing each other's sentences as they talked to Haruhi.
* Happens in the finale of ''StellviaOfTheUniverse'' between Richard James and Carl Hutter when the two are having a few drinks on a desolate space station deck. James raises a toast, starting with "To the future...", and Hutter completes the sentence instantly, in the same tone: "...of humanity!" This is especially poignant, considering how [[spoiler:Hutter is a shape-shifting StarfishAlien in disguise... and James knows it]].
* While not the most typical example of twins, in ''Manga/CardcaptorSakura'', Yue and Cerberus pick a climactic moment during the final judgment to suddenly start finishing each other's sentences--with multiple clauses, no less. In fact, despite their apparent hostility toward each other at the time, it becomes nearly impossible to distinguish exactly ''who'' is speaking at some points.
* ''GunslingerGirl''. Cyborg technician Louis Duvalier has beautiful twin assistants who do this. They even move in unison.
* Koizumi and Otani from ''LovelyComplex'' are so (unintentionally) good at this that they (again, unintentionally) become a comedy sensation at their school.
* Some of Arron and Gurran's early dialogue in ''ArmoredTrooperVotoms'' consisted of this, when it wasn't just TwinBanter.
* In ''Manga/DetectiveConan'', whenever Conan and Heiji get to work together in a case they will often finish each other's deductions, demonstrating not only abilities as detectives, but also their familiarity with each other.
* In ''Manga/ACertainScientificRailgun'', the Sisters initially switch which is speaking every few words.
* Fine and Rein from ''Anime/FushigiboshiNoFutagohime'' tend to finish each other's sentences when they don't SpeakInUnison.

* In the ''ScottPilgrim'' books, Ken and Kyle Katayanagi often finish each other's sentences with their reasoning behind it being that they would always work together after Ramona cheated on them behind their backs. This was obviously not in the movie as the only line the Twins have in the film is "Hah!" during a fight sequence.

* The Weasley Twins, from ''Literature/HarryPotter'' are '''''not''''' an example, even though they are popularly portrayed that way in Fan Fiction. They don't complete each other's sentences in the books; rather, one will follow the other with the next appropriate sentence - they do not share a single mind, but simply think very much alike.
** The ideal is Lampshaded in Fanfic/HarryPotterAndTheMethodsOfRationality, which features a sections focusing on the Twins, and indicating something magical is at work. They don't actually share one mind, but come to the same conclusions when they have the same information. When one of them thinks differently than the other, they both feel uncomfortable until they share what they know and snap back.

* The Fates from Disney's ''Disney/{{Hercules}}'' do this, most noticeably in their introduction, when they're giving Hades the prophecy.
* Tweedle Dum and Tweedle Dee in Disney's ''Disney/AliceInWonderland'' (but not in the original book).
* The twins in ''WesternAnimation/BarbieInAChristmasCarol''.
* In ''Disney/{{Frozen}}'' Hans and Anna combine this with StrangeMindsThinkAlike when Anna completes his line about how people who are in love finish each others - [[Series/ArrestedDevelopment sandwiches]], and Hans exclaims that that's just what he was going to say.[[spoiler: This turns out to be a lie. He's trying to get her to marry him as part of his plan to usurp the kingdom.]]
* In ''WesternAnimation/TheNightmareBeforeChristmas'', the troublemakers Lock Shock and Barrel do this at their introduction.

[[folder:Film--Live Action]]
* From ''ScaryMovie 4'':
-->'''Cindy Campbell''': It looks like we have a lot in...\\
'''Tom Ryan''': ...common.\\
'''Cindy''': We're already finishing each other's...\\
'''Tom''': ...dinner!\\
'''Cindy''': ...sentences.
* The twins from ''{{Snatch}}'' do this.
* In ''Film/StuartLittle'', Mr. and Mrs. Little do this so frequently that they panic when they ''don't''. Stuart cutely lampshades this as he hears his future adoptive parents do this for the first time.
* From ''Film/DeadMenDontWearPlaid'':
-->'''Field Marshal Von Kluck:''' We were able to dupe Dr. Forrest by posing as a humanitary organization, who planned to wipe out hunger, by ageing cheese faster.\\
'''Rigby Reardon:''' But when your father finally saw what they were doing...\\
'''Field Marshal Von Kluck:''' --he began to assemble lists of names of our agents...\\
'''Rigby Reardon:''' --and seemed about to go to the FBI.\\
'''Field Marshal Von Kluck:''' We were zerfore obliged to kidnap him, drug him ang bring him...\\
'''Rigby Reardon:''' --here! First faking his death so there'd be no further investigation.\\

'''Rigby Reardon, Field Marshal Von Kluck:''' --friends systematically began to eliminate everyone who was on that cruise ship.\\
'''Field Marshal Von Kluck:''' Schweinehund!\\
'''Rigby Reardon:''' Jerk!
* In ''{{Film/Bridesmaids}}'', the main character is talking to a smugly newlywed couple and asks where they went on their honeymoon. They both say, "Disney World," and then the wife adds, "Sorry, we finish each other's sentences," as if there was any way they weren't both going to say the same thing.

* Creator/RobertAHeinlein's Lapis Lazuli Long and Lorelei Lee Long are clone sisters who do this. They first appear in his novel ''Literature/TimeEnoughForLove'' and show up in his later novels.
** Castor and Pollux Stone, twin brothers from ''Literature/TheRollingStones'', do the same to their father's annoyance.
* There is a Creator/JamesThurber short story about this, called "The Curb in the Sky," where the trope has harrowing consequences.
* Harry and Hermione do this sometimes in ''Literature/HarryPotter'', such as in ''[[Literature/HarryPotterAndTheDeathlyHallows Deathly Hallows]]'' when they discover what happened to [[spoiler: Gryffindor's sword]].
** In {{Fanon}}, SingleMindedTwins Fred and George Weasley are often written as doing this. In the books it only happened a couple of times and was more like collaborative interrupting. The movies were much more guilty of playing this trope straight with them.
* The twins Beltira and Belkira from the ''Literature/{{Belgariad}}'' and prequels.
--->"Belgarath, our brother," one of them said, "it's been such--" "--a terribly long time," the other finished.\\
"Beltira," Belgarath said. "Belkira." He dismounted and embraced the twins.\\
"Dearest little Polgara," one of them said then. "The Vale has been-" the other started.\\
"--empty without you," the second completed. He turned to his brother. "That was very poetic," he said admiringly.\\
"Thank you," the first replied modestly.
* ''Elenium'' by the same author.
** Danae and Sarabian
--->'Right,' she agreed. 'Tamul skin tone would be better with--'\\
'But not red-red, though. More scarlet, perhaps even--'\\
'No. Maroon's too dark. It's a ball, not a--'\\
'We don't wear dark clothes at funerals. We wear--'\\
'Really? That's a very interesting notion. Why do you--?'\\
'It's considered insulting to--'\\
'The dead? They don't really mind, Sarabian. They're busy someplace else.'
** Danae, however, has the added advantage of being [[spoiler:the goddess Aphrael]], so her intellect would obviously surpass that of Sarabian's, as she says he is not so bad himself when he comments that she is a stimulating conversationalist.
* This was one of the traits that gave ''Literature/{{Mash}}'''s 'Radar' O'Reilly his nickname, and one of the parts of the book faithfully translated into the subsequent film and television series.
* [[DragonRider Dragons and their riders]] in ''Literature/InheritanceCycle'', notably Oromis and Glaedr in ''Eldest'' and Eragon and Saphira in ''Brisingr.''
* A variant in the {{Starcraft}} novel ''Liberty's Crusade''. Kerrigan, being a telepath, tends to finish other people's sentences out of habit, which annoys just about everyone else. When she's leaving for her totally-not-a-date with Raynor after the Antiga mission, Liberty's last bit of advice is "remember to let him finish his damn sentences".
* In ''Literature/TheHungerGames'', [[CloudCuckoolander Wiress]] tends to trail off or just stop speaking abruptly in the middle of her sentences, at which point Beetee finishes them.
* In Spindle's End by RobinMcKinley, Rosie and her best friend Peony take this one step further.
-->You finish each other's sentences half the time -- or sometimes, if you think no one else is listening, you don't bother to finish them because you both know what you were going to say.
* {{Lampshaded}} in ''Literature/ArtemisFowl and the Opal Deception''. Mervall and Descant are twins, which are very rare among fairies.
-->"We're thinking of writing a book, aren't we, Merv? All about how we..."\\
"Finish each other's sentences," completed Merv, though he knew it would cost him.\\
"Shut up, you utter imbecile," snapped Opal, shooting Merv a poisonous glare.
* Reynolds and Claude's promotion interview in the penultimate chapter of ThePaleKing. [[spoiler: Chris]] incredulously wonders how long they had to practice it.
* The Judy Blume book ''Double Fudge'' features [[SingleMindedTwins single-minded twins]] Flora and Fauna Hatcher, who do this ''constantly'' - much to Peter's annoyance.
* The Force-Sensitive Tash Arranda in ''Literature/GalaxyOfFear'' often finds herself finishing people's sentences, whether she knows someone or not. Sometimes this and her [[PsychicChildren other talents]] make her come off as a CreepyChild, but part of the time she doesn't even know she's doing it. It causes her some trouble in ''Eaten Alive'', when Leia Organa starts introducing herself and Han immediately gets suspicious. She also sometimes does it deliberately, as in ''City of the Dead'' when she's annoyed at an HonestJohnsDealership and is pleased by how easily she can keep it up, thinking that the pushy proprietor must be shallow.
* In ''{{Literature/Shatter Me}}'' the healer twins Sonya and Sara both finish the other's sentences as well as speak completely in unison at times.

[[folder:Live Action TV]]
* In ''Series/HappyEndings'', this comes up when Jane is talking about the sister bond she has with Alex.
-->'''Jane:''' Even when we were kids, we would always finish each other's-\\
'''Alex:''' Pizza.\\
'''Jane:''' I was going to say sentences. But that works too, because I was not much of a crust girl.
* ''Series/{{Psych}}''
** Shawn and Gus do this all the time. When Gus pairs up with Lassiter, they start doing this as well. Subverted when Juliet and Shawn try to pull this off as well.
--->'''Juliet:''' Well, we have a h--\\
'''Shawn:''' --hamburger!\\
'''Juliet:''' ''[at the same time]'' --hunch. What the hell?\\
'''Shawn:''' You made an ''H'' sound.\\
'''Juliet:''' ''[[[{{Corpsing}} trying not to crack up]]]'' And you went with ''hamburger?''
** Later gets a {{callback}} when Gus and Shawn partner back up. More or less:
--->'''Shawn:''' Wanna grab snacks?\\
'''Gus:''' You know that's right. How about--\\
'''Shawn and Gus:''' ''[triumphantly]'' ''Hamburger!''
* Played with in [[Recap/CommunityS1E18BasicGenealogy an exchange]] in a ''Series/{{Community}}'' episode:
-->'''Abed:''' I hope they’re not twins. Twins freak me out. They always know what the other one is...\\
'''Troy:''' Thinking.\\
'''Abed:''' Yeah. And they’re always finishing each other’s...\\
'''Troy:''' Pie.\\
'''Abed:''' It’s creepy.
* ''SpinCity'' got meta:
-->'''Carter:''' Mike, you and Caitlin are in danger of becoming one of those couples that claim you're apart, but in reality you're...\\
'''Stuart:''' ...so close that you finish each other's sentences. And the problem with that is that people like that inevitably end up...\\
'''Carter:''' ...romantically involved.
* A ''Series/MontyPythonsFlyingCircus'' sketch had a housewife receive a visit from a doorman who helped her finish sentences by first finishing them for her, then starting them so that she'd have to finish them.
** Another ''Python'' sketch had an interview show with the host interviewing three men: one who only said the beginnnings of words, one who said the middles, and one who said the ends. After each said their own version of "Good evening," he had them all say "Good evening" together.
--->'''First man:''' G--\\
'''Second man:''' --oo--\\
'''Third man:''' --d\\
'''First man:''' ev--\\
'''Second man:''' --eni--\\
'''Third man:''' --ng.
* ''Series/ArrestedDevelopment''
** Similar to the ''Series/{{Community}}'' example, there was this exchange:
---> '''Michael:''' It's like we finish each others'--\\
'''Lindsay:''' sandwiches?\\
'''Michael:''' ... sentences. Why... would I say...\\
'''Lindsay:''' sandwiches?\\
'''Michael:''' ''That'' time I was going to say "sandwiches".
** The fourth season used this twice, when Tony and Gob figure out how much they have in common and end up simultaneously spouting nonsense in an attempt to evoke this ("The last time... I went... scuba diving... while eating... Captain Crunch"), and in an exchange between Lindsay and Herbert Love that explicitly calls back to the earlier episode:
--->'''Lindsay:''' It's like we finish each other's...\\
'''Love:''' Sandwiches!
* Jack and Ianto do this in ''Series/{{Torchwood}}'' in Day One of Children of Earth
-->'''Jack:''' Persistent--\\
'''Ianto:''' Good sign.\\
'''Jack:''' Dogmatic--\\
'''Ianto:''' Always a plus.\\
'''Gwen:''' Oh, Christ, never work with a couple, you two talk like twins!
* In ''BrokenNews'', the newscasters for PVS News routinely complete each others' sentences, or even words.
* Lampshaded by Brian in a season five episode of ''QueerAsFolk'' after Justin has told him to stop being cynical:
-->'''Brian:''' I'm not being cynical, I'm being--\\
'''Justin:''' --realistic.\\
'''Brian:''' Do you mind if I finish my own sentences? I despise when couples do that.
* Sheridan and Delenn in ''Series/BabylonFive'' do this a little.
* Attempted in ''They Think It's All Over'':
--> '''Rory:''' Gary and I have been working together for so long that we can actually...\\
''[long pause]''\\
'''Gary:''' ...finish each others' sentences?
* ''Series/{{Castle}}''
** It happens so frequently between Castle and Beckett that fellow detectives overhearing their conversation had to Lampshade it:
--->'''Ryan''': Do they ''know'' that they're finishing each other's sentences?\\
'''Esposito''': ''[just shakes his head]''
** Another time, Ryan asks if they practice doing it when he and Esposito aren't around.
--->'''Lanie''': It's so ''cute'' when you guys do that.
* ''Series/{{NCIS Los Angeles}}'' has Nell annoying the hell out of everyone by doing this on her first episode. CharacterizationMarchesOn, though, and now she's just doing it to Eric. It's played for laughs, and incredibly cute. Other partners on the show tend to do this as well.
* All over the place on ''Series/{{NCIS}}''. [=McGee=]/Abby, any partners, any time the field agents brief Gibbs, any time Gibbs gives orders and the others anticipate him . . .
* Gem and Gemma from ''Series/PowerRangersRPM'' do this habitually; they don't speak ([[SingleMindedTwins or think]]) as individuals much if at all until Gemma gets a boyfriend. After that, while they show signs of not being a HiveMind, but still do this frequently. Just not ''all the time''.
* Kirk and Spock do this occasionally in ''Series/StarTrekTheOriginalSeries''.
** In ''Series/StarTrekTheNextGeneration'' there is a whole race known as the Binars who talk this way because of their binary/pair based culture and biology.
* ''NoahsArc'': Subverted in the movie where Noah and Wade seem to start to give the same answers to relationship questions, but end with completely different ones. This is the first major sign they're have deeper relationship issues.
* A recurring sketch on ''TheTwoRonnies'' featured Corbett's character trying to tell a story, and Barker's character attempting to finish his sentences and getting it wrong.
* On ''Series/TheWestWing'', Will Bailey and Kate Harper do this in front of C.J., while trying to hide the fact that [[spoiler: they're a couple]]. Both lampshade how bad they are at it.
* ''Series/StargateAtlantis''
** In the episode ''Sateda'', Teyla attempts to do this with Sheppard; however it takes her three guesses to figure out what he's saying, and at one point she offends him by saying he has no friends.
--->'''Sheppard''': Look, Teyla... I'm not really good at, uh... actually, I'm... I'm terrible at expressing... I don't know what you'd call it, uh...\\
'''Teyla''': Feelings?\\
'''Sheppard''': Yeah, sure, okay. The point is, I don't really have good, uh...\\
'''Teyla''': Social skills?\\
'''Sheppard''': Well, that is why I enjoyed flying choppers in the most remote part of my world before all this craziness happened, but, uh, you should know, I don't have, uh...\\
'''Teyla''': Friends?\\
'''Sheppard''': No. I have friends.\\
'''Sheppard''': You, Elizabeth, Ronon, Carson, even Rodney, are the closest thing I have to a...\\
''[she finally gets it]''\\
'''Teyla''': A family?
** Sheppard and Elizabeth manage it more successfully in a few episodes.
* In the ''Series/DoctorWho'' episode [[Recap/DoctorWhoS32E6TheAlmostPeople "The Almost People"]], the Doctor and a doppelganger of the Doctor do this.
** Ten and Eleven constantly do this toward the end of "[[Recap/DoctorWho50thASTheDayOfTheDoctor The Day of the Doctor]]".
* In ''Series/BoardwalkEmpire'', Esther Randolph and her assistant use this trope to great effect as an interrogation technique when trying to needle Ray Halloran for information. Halloran even makes a joke about the two of them being married (they're actually only sleeping with each other).
* There are two main examples in ''Series/{{Bruiser}}''. In the sketches with the cops doing a documentary, Mitchell's cop often has to finish the more talkative cop's (played by Webb's) sentences after he blunders over a saying or description. This trope is also the whole point of a series of sketches starring Charlotte Hudson and Olivia Colman as two friends in a pub discussing their sex lives. They frequently finish each other's sentences, until Colman invariably goes just a little too far.
* ''Series/{{JAG}}'': Jennifer Coates does this several times, after she replaced Tiner as the Admiral’s yeoman in season nine, and is a source of irritation to the Admiral.
* [[TearJerker Heart-breakingly played with]] in the last episode of ''Series/{{Blackadder}}'', Captain [[UnfortunateNames Darling]], long the desk jockey of the season, is being unwilling [[UsefulNotes/WorldWarOne sent over the top, and to certain death]], by his commanding officer, and all his attempted protests are cut off:
-->'''Darling''': But sir, I don't want to...\\
'''General Melchett''': Leave me, well I appreciate that Darling.\\
'''Darling''': No sir, I don't want to go into battle...\\
'''Melchett''': Without me?
* Fitz-Simmons do this a lot in ''Series/AgentsOfSHIELD'', since they're TheDividual. At best, they actually manage to stop at finishing one another's sentences; at worst, they talk over each other to provide synonyms, or sometimes even have a short argument, before ending on the same word - leaving the middle of the sentence incomprehensible to most everyone else.
** In Episode 8 of Season 1, Fitz is sent on his first field mission without Simmons, who out of loneliness and anxiety starts trying to finish Skye's sentences instead, which just ends up getting on her nerves.
--->'''Skye:''' Do you realize you keep finishing my -
--->'''Simmons:''' Sentences? Sorry, bad habit!

* In a TV Week interview, Hamish Blake and Andy Lee were talking about their close friendship.
-->'''Andy''': We--\\
'''Hamish''': --finish each other's sentences.\\
'''Andy''': I wasn't going to--\\
'''Hamish''': --say that.\\
'''Andy''': Well done, you got that one.

[[folder: Newspaper Comics]]
* A ''ComicStrip/{{Dilbert}}'' [[http://dilbert.com/strips/comic/2002-04-16/ strip]] features a guy who does that in a sinister way:
-->'''Dilbert:''' I think I should take...\\
'''Sentence Finisher:''' Money from orphans?\\
'''Dilbert:''' No. I mean, I need...\\
'''Sentence Finisher:''' A large sack and an alibi?\\
'''Dilbert:''' You keep finishing my sentences with...\\
'''Sentence Finisher:''' Uncanny accuracy?

[[folder: Stand-up Comedy]]
* This is a crucial part of the stand-up act of Randy and Jason Sklar, as they are identical twins with exactly the same voice who seem to run on the exact same wavelength at all times. They practically turn finishing each other's sentences into a zen artform.
* Tim Hawkins jokes about newlyweds who do this in [[http://www.youtube.com/watch?v=zzAY1ZGvhwo&list=UUDYmrqySCqrHnah4LNUPt4w&index=50 one of his routines]].

* One performance of ''HenryVI Part II'' has Suffolk dragged offstage and killed before delivering his last line, leaving it to be completed by the pirate captain, which adds a wonderful creepiness to the scene.
-->'''Suffolk:''' Great men oft die by vile bezonians:\\

-->'''Roger:''' Oh, the wax. It's--\\
'''Mimi:''' Dripping. I like it, between my--\\
'''Roger:''' Fingers.
* ''The Serpent'', a dark version of the [[Literature/TheBible Adam and Eve]] [[AdamAndEvePlot story]].
** The Serpent manages to do this to ''itself'' [[EvilGloating every time it speaks]]. The Serpents' lines often also [[MeaningfulEcho overlap words]] and start before the previous line finishes.
--->'''Serpent 3:''' You might\\
'''Serpent 4:''' Might do it if God didn't know?\\
'''Serpent 2:''' But you want to.\\
'''Serpent 1:''' And [[TheOmniscient he knows]] [[ForbiddenFruit you want to]].\\
'''Serpent 5:''' [[SchmuckBait Is a crime]]\\
'''Serpent 4:''' Only a crime\\
'''Serpent 5:''' [[NotCheatingUnlessYouGetCaught When you're caught?]]
** The [[GreekChorus chorus women]] also do this, though without the overlap.
--->'''First WC:''' Old stories have a secret;\\
'''Second WC:''' They are [[EpiphanicPrison a prison]]:\\
'''Third WC:''' Someone is locked inside them.\\
'''Fourth WC:''' Sometimes, when it's [[ItsQuietTooQuiet very quiet]], I can hear them breathing.
* In ''Theatre/TheGondoliers'' by Creator/GilbertAndSullivan, when Marco and Giuseppe agree to jointly become the King of Barataria, they announce this in a verse where each of them sings only every other bar. It works like this, with Marco's part in plain text and '''Giuseppe's''' in boldface:
-->''Replying, we '''sing'''\\
'''As''' one indi'''vidual,'''\\
'''As I''' find I'm a '''King,'''\\

'''Rosalind:''' The fact that we sometimes--\\
'''Robert:''' --finish each other's sentences?

* In Website/ThatGuyWithTheGlasses 3rd year anniversary special ''WebVideo/SuburbanKnights'', the two groups, on a quest to find a hidden treasure, in seperate locations, invoke this trope.

'''Nostalgia Chick''': ...got to be...\\
''[cut to WebVideo/ToddInTheShadows]''\\
'''WebVideo/ToddInTheShadows''': ...fucking...\\

'''NC''': ...KIDDING ME!!\\
''[camera cuts to show they are right back where they started]''
* Parodied in WebVideo/TheNostalgiaCritic's review of ''The Odd Life of Timothy Green''. Constantly annoyed at how the lead couple can always perfectly complete each other's sentences, he imagines what it'd like to see a couple completely misinterpret them. Cue skit.
-->'''NC''': It didn't matter where it came from.\\
'''Rachel Tietz''': ''[as his wife]'' He was ours.\\
'''NC''': We were his.\\
'''RT''': We were a family.\\
'''NC''': It was the greatest day since--\\
'''RT''': --he discovered Viagra.\\
'''NC''': ''[{{beat}}]'' ...that wasn't what--\\
'''RT''': --a penis should look like, until he started taking it.\\
'''NC''': If you let me finish--\\
'''RT''': --he would say all the time, but nothing ever came out!\\
'''NC''': We shouldn't talk about this--\\
'''RT''': --without visuals! ''[pulls out drawing depicting a crying NC and angry wife in bed]''\\
'''NC''': Jesus Christ!\\
'''RT''': He would cry every night until I showed him the online ad!\\
'''NC''': Dammit, honey, this is already hard enough!\\
'''RT''': --was the name of the brand we got!\\
'''NC''': This, this is--\\
'''RT''': --why we can't have children.
