Pair the Spares

"Marge: It's about time Mr. Burns found a woman. I can't stand to see a man single. Lisa: Some people enjoy being alone, Mom. Marge: No, everyone should be paired up."

- The Simpsons, "A Hunka Hunka Burns in Love"

Two characters, Alice and Bob, are an Official Couple, but Charlie is also interested in Alice, and Doris is pursuing Bob too.

When Alice and Bob finally go from Official Couple to actual couple, Charlie and Doris are left in the cold. Still, both of them have experienced the pain of heartbreak and unrequited love—so why not hook them up together? They may not have any initial attraction to each other, but they can always hang out and reminisce about their similar failed romances, and somewhere along the way, they might just find mutual love with each other like their former partners have.

While it's nice to see Charlie and Doris get a happy ending of their own, this device can very easily reek of red string puppetry and make viewers suspect that the creator just paired them off to permanently get them out of the main couple's way.

Differs from No Loves Intersect in that the leftover pairings are not immediately obvious and the involved people are initially just part of the Love Dodecahedron.

See Ship Mates for when the fandom does this in Fanfic. Compare Sexual Karma, Lonely Together and Beta Couple.

General
"There is a fifty-fifty chance that the Hero's Sidekick is in love with me. I'll find him a spunky, moderately-attractive tomboy type about his height, and steer them towards each other. If they quarrel, they're in love; if they hit it off, she loves him, but he's secretly unhappy with her and still loves me, and the Hero will need to send them off on a mission together."
 * This is more or less described in The True Love List, the Love Interest's counterpart to the Evil Overlord List. Rule #32 as follows:

Anime & Manga

 * Satoshi and Risa in D.N.Angel. Its begin as anime-only hints in the end (that exchange of looks and smile can't be platonic, really), and become a popular Ship Mates ever since. The existence of the pairing is acknowledged by the manga (sort of) with them having a lot of screentime together and truckload of romantic vibes and chemistry (though D.N.Angel as a whole tend to tease everyone x everyone so whether they end up with each other in the end is still questionable).
 * Hiro and Ayaka from Gravitation. Initially, Ayaka was Yuki's arranged fiancée and Hiro was Shuichi's implicitly bisexual childhood friend; both of them push their partners to be with one another, and began dating each other.
 * Rizelmine's entire Love Dodecahedron gets resolved this way, down to one girl getting paired off with a dog that had molested her in an earlier episode.
 * Ginta and Arimi find love in Marmalade Boy in just this way. After chasing Miki and Yuu, they give up simultaneously on them and then fall in love with each other.
 * The same thing also happens to the American cast, more or less. In that case no one ends up with the person they originally wanted (or appeared to want).
 * The Kidou Tenshi Angelic Layer manga pairs up Tamayo and Oujirou, who had previously shown slight interest in Koutarou and Misaki, respectively. (The anime, on the other hand, flips the pairings, putting Tamayo with Koutarou and Oujirou with Misaki anyway.)
 * Technically, the anime doesn't have Oujirou WITH Misaki, so much as stalking her. Alongside Icchan's Stalking of Misaki's MOM.
 * Mugen Densetsu Takamagahara Dream Saga gives Souta, Yuuki's quiet admirer, to Nachi, Takaomi's Clingy Jealous Girl.
 * In Ranma ½ fanfiction, this happens very often, mostly with Ship Mates type pairings. These writers mainly get their basis from the presence of Ship Tease for gags/storylines and short-lived moments of in-series Shipper on Deck: most of the characters in the Love Dodecahedron know that if their rival falls in love with somebody else, then whoever they want is sure to fall into their arms. This is why Ukyo promotes Ryoga with Akane, why Mousse promotes Ranma and Akane (and probably would support Ranma with Ukyo or Ryoga and Akane, if the ideas ever arose), and why Akane is quite willing to promote the idea of Ukyo and Ryoga or Shampoo and Mousse. Nabiki and Kuno are a popular fan couple due to a combination of some Ship Tease (a manga Filler story has them temporarily become enchanted with each other after being caught by a Love Potion version of the Together Umbrella, while an anime one has Kuno mistakenly being predicted as destined to marry Nabiki), though this invariably ends with Ship Sinking, and the fact that Kuno is Rich in Dollars, Poor In Sense and Nabiki's Money Fetish makes her easy to picture her hooking up with Kuno for his money.
 * The Fruits Basket manga does a pretty amazing job at this - two dozen characters all get paired off before the end.
 * The two exceptions among the main characters are . Among the eligible minor-but-relevant characters, only four are left. Fanfic authors, start your engines.
 * Happens at the end of After War Gundam X. And while it may have been an Ass Pull, it was an awesome Ass Pull.
 * Lampshaded in Mahou Sensei Negima, despite having not actually happened yet. Natsumi reasons that she can't make a pactio (it requires kissing, but not necessarily coupledom) with Negi, because he's the protagonist and she's just "a side character". She then reasons that she could only do it with "the one guy who's in the same 'side-character' position as me" (Kotaro), with whom she has quite a bit of Will They or Won't They? subtext.
 * Macademi Wasshoi has one of the weirder versions of this. At the end of the series, we have Takuto's harem still after him, though with Metallis being a huge supporter of Suzuka. Metallis' former sidekick George has been paired up with Macho Camp angel Hapshiel. It's a healthy, if somewhat bizarre, relationship.
 * There are Naruto fans who pair Hinata with Rock Lee.
 * Itazura na Kiss is guilty of this with.
 * The Mahoromatic epilogue reveals that  married in the future.
 * In Code Geass, it is arguably implied that fan-favorite Jeremiah Gottwald aka Orange-kun surprisingly ends up with Anya. Then again, it's not really made clear. She could just have been unofficially adopted by him or something along those lines. Your Mileage May Vary.
 * Some people assume they pair up (the age difference isn't as big as it looks), some assume he adopted her/they're Like Brother and Sister now, and a large faction of Fanon has decided Jeremiah hooked up with and married Sayako offscreen and the two adopted Anya together.
 * It's more or less common to pair up Gino with Kallen in Fanon, too.
 * Seems to be the main reason for Shugo Chara Encore. Chapter 1: Utau/Kuukai. Chapter 2: Rima/Nagihiko. Chapter 3: Yaya/Kairi.
 * Sailor Moon does this with Umino and Naru. Umino had a thing for Usagi, but she ended up with Mamorou. Naru was in love with Neflite, but he up and died on her. The two end up together despite having shown no attraction to each other in past episodes.
 * To their credit, though, they're the only characters other than the main pair who can maintain a relationship for more than one episode...
 * They get together just in time to vanish from the show almost completely, along with nearly every other supporting character who isn't directly connected to the Senshi. They do tend to get one token appearance per season, though, and they seem more in love each time.
 * In Fullmetal Alchemist near the beginning of the series everyone was familiar with the three bordering canon couples Edwin, Royai and Lingfan, and thought that was all we'd get- but wait what's this? Mei's got a crush on Al? Olivier and Buccaneer have a talk on the rooftop? Bradley actually cares about his wife? Rebecca and Havoc are the cavalry? Ohhh myy...
 * In The Lucifer and Biscuit Hammer, out of the 9 surviving Beast Knights only two of them didn't pair up.

Comics

 * In Invincible, after Mark (the title character) starts dating Amber, his best friend William starts dating Mark's ally/secret crush Atom Eve. It sort of makes sense because they both know Mark's identity, but when Eve realizes how immature William is, they break up after a few issues.
 * And, yup,
 * A December 1993 FoxTrot storyline had Peter in conflict over whether or not he should take new character Mindy, who has a crush on him, to the Christmas dance, thus hurting the feelings of his girlfriend, Denise (who's taking a vacation to her grandmother's). In the end, though, Peter's problem is solved when Mindy falls in love with his friend Steve (and then mysteriously vanishes from the strip afterwards).

Film - Animated

 * At the end of the second Toy Story movie, we already know that Woody would be with Bo Peep, so it left out his sidekick Jessie. But of course, there's the perfectly available Buzz right there ...
 * Which actually does make sense, considering both Jessie and Woody are from the Woody's Roundup family. Unless you were suggesting ...
 * Awfully ironic after watching Movie 3. I think I got "irony" right.
 * (Not really) Their relationship was more of a Last-Minute Hookup. The relationship was given a lot more development in 3.
 * In Gnomeo and Juliet, Juliet's father tries to set her up with Paris. Unlike in the play, he survives and winds up falling for Nanette, Juliet's friend (roughly equivalent to the Nurse).

Film - Live-Action
"Tracey: I don't mean to criticise, you probably have other interests outside your work. Mike: None. (looks at Liz, scrambles to recompose) I mean--us-- Tracey: How sweet."
 * An early script for You've Got Mail has Kathleen (Meg Ryan) and Joe (Tom Hanks) trading partners by the end of the film. This was dropped by the time filming was done.
 * Many screwball comedies, from The Philadelphia Story (the reporter and his female assistant are told they should get together, when they've shown absolutely no interest in each other throughout the movie) to The Palm Beach Story (the couple considering a divorce decide to get back together, but tell their paramours they both have identical twins, leading to a triple marriage at the end).
 * Oddly enough in the musical version the assistant has a crush on him for the entirety of the play.
 * Shown absolutely no interest in each other? It's pretty clear that Mike and Liz are in a relationship in The Philadelphia Story.


 * Done for laughs at the end of Baseketball. Coop ends up with his love interest Jenna, and Squeak embraces the possible transsexual he has been sharing looks with. Remer on the other hand looks despondent until he meets gazes with Yvette, a character he has had no interaction with throughout the movie. They immediately begin making out.
 * In Enchanted, leftovers  spontaneously get together. They hadn't even really talked to each other until the end, but hey, fairy tale! So next thing you know, they're getting married. What makes this even more annoying is that this pairing doesn't even follow the "Love At First Sight is impractical, but love after two or three days is fine" message in the film.
 * YMMV as to whether or not this is Broken Aesop. Considering they are seen getting married as part of an epilogue montage that includes  and , it is implied that some time passes, since both of those scenarios would need some passage of time to occur.
 * Even with the implied passing of time, it's still hard to tell whether they broke the Aesop or not, given how it's an Affectionate Parody of Disney's other princess movies, where Fourth Date Marriages are quite common. ...Well, it's probably a parody, anyway.
 * They also explicitly travel to Andalasia to get married (rather than in the "real" world), where the fairytale nature of the realm can make spontaneous love work. It's quite probable that they literally live happily ever after.
 * Although in the novel, the pairing was actually set up quite nicely and built up pretty well in the background of everything else that was going on, the movie version of The Lord of the Rings makes the Faramir/Éowyn pairing seem like a version of this trope. Éowyn loses out on Aragorn and gets his "slightly inferior replacement" of sorts. It's a shame, too, because the imagery of the two recovering together in the Houses of Healing was one of the nicer images from the book, both Éowyn and Faramir got quite the Character Development out of their scenes, and Faramir's proposal to Éowyn is the closest thing the book has to an actual romantic speech. Whereas in the movie, the whole implied romance comes and goes in the space of a single reaction shot. There's more shown in the extended version, but still...
 * Saving Silverman parodies this; the protagonist marries his childhood sweetheart, and the evil Disposable Fiancée is paired off with his best friend, but then Jack Black's character (who has mentioned he might be gay) marries R. Lee Ermey (playing himself, as usual).
 * Taken to its logical extreme in Billy Madison, which ends with just about every character who got at least one line sharing passionate kisses (including an imaginary penguin).
 * In High School Musical 3, all of the main cast is paired except for Ryan, the closest Disney will ever get to having an openly gay character, and Kelsi, who has been the source of a heated debate over whether or not Disney also put a lesbian in the film. So, naturally, Disney covers their butts from the many people who would have objected to having homosexual characters in a Disney film, and pairs them up. That said, all they do is sing a duet together, and have no other screen time together.
 * In the stage version, Kelsi is paired with Jack Scott (who doesn't appear in the films). This is done right at the end with no explanation. The two have about five seconds of dialogue.
 * In the musical Seven Brides for Seven Brothers, this is the premise from the beginning; 6 of the titular brothers, unhappy that the oldest of them is to be wed, kidnap 6 girls from the nearby town and try to Stockholm-seduce them over the winter.
 * Parodied, then played straight with a little justification in Mean Girls. The remainder of the Power Trio (one a gay guy, the other probably not a lesbian) have an Almost Kiss at the final dance, before being mutually disgusted and breaking apart. Then another minor character, who's actually shown an interest in the girl previously, finally gets his chance.
 * Happens in Old School with Frank The Tank and Heidi (Luke Wilson's swinger girlfriend from the beginning of the film). Granted, Frank and Heidi would probably be a pretty good couple.
 * Surprisingly averted in the romantic comedy He's Just Not That Into You. Three characters.
 * In She's the Man, the main characters' mean exes wind up together.
 * Implied with in the film version of V for Vendetta.
 * Also implied with Uncas and Alice in the film version of Last of the Mohicans.
 * Basically the plot of the 1997 Meg Ryan/Matthew Broderick vehicle Addicted To Love.
 * In the final Harry Potter film, Neville throws in a line about wanting to find Luna and finally tell her that he's "mad about her." Though definitely a Fan Preferred Pairing, they never hook up in the books. (The filmmakers says that they only have a summer fling, but who cares what they think?)
 * Done very literally in The Pirate Movie (based loosely on The Pirates of Penzance): in a moment of Time Stop at the climax of the film, Mabel physically pairs each of her dozen sisters with one of the pirates (and in one case, two of the pirates with each other) so that she and Frederick can be together without too many complications.
 * Invoked In-Universe by Phil and Judy in White Christmas -- by pretending to pair themselves off with a phony engagement, they hope to smooth the way for Bob and Betty (partner and elder sister, respectively) to get together. There are of course complications along the way, but eventually both pairs get together for real.

Literature

 * Author J.K. Rowling of Harry Potter fame said in an interview that although she left open the possibility of a relationship between many characters such as, she didn't explicitly state one in the wrap-up because it "felt too neat."
 * Inversion in OotP: the spares hook up before the Official Couple.
 * In Twilight, pretty much every character gets a Love Interest. Except Leah. Some have criticized this, since it seems to tie into a theme of romance being the only important thing in a person (especially a woman)'s life. Even the baby gets betrothed! At a few days' old! To !
 * As mentioned in the Film section, Eowyn/Faramir from Lord of the Rings (though to a much lesser degree). Apparently this happened because Tolkien originally intended for Eowyn to die fighting the Witch-King, but his wife thought that was too despressing, and that Eowyn should get a happy ending too.
 * In the Belgariad, this ends up happening to many of the supporting characters, such as,  , and  . In fact, several of these characters aren't even mentioned until the second quintet, which suggests that the characters were created specifically for this trope.
 * Justified in that The Destiny is a huge Shipper on Deck. Polgara remarks that people who aid Destiny will be rewarded by finding happy love. At no point does anyone entertain the notion of being happy alone.
 * Beldin is quite happy alone. Belgarath also spend lots of time wandering the earth or doing research in his tower with little to no interaction with the outside world and liked it this way. But they are happier when Destiny-shipped.
 * In Agatha Christie's Appointment With Death,  get paired up in the epilogue. This probably isn't all that unlikely, but it comes out of nowhere nevertheless.
 * Generally subverted in PG Wodehouse's books (Blandings Castle, Jeeves and Wooster, etc), in which a typical plot might go as follows: A loves B, and C loves D. But just before the book starts, A and B break up over something, and A, seeking to show he's not heartbroken (though he is) proposes to D, who is temporarily convinced that C is a complete bastard. Then everything gets disentangled. Subverted in that the eventual pairings are set up quite early on in the book. This formula is then livened up by wonderfully eccentric characters, hilarious plot twists, and fabulously funny writing.
 * The Fionavar Tapestry series of books begins with five protagonists transported from Canada to the magical world of Fionavar: over the course of the trilogy, two die and one decides to stay in Fionavar after hooking up with a local woman. The remaining two decide to return to Canada, and on the last page they decide to go on a date, with no particular buildup to this in the preceding 700+ pages.
 * Taken to an extreme in Orson Scott Card's Homecoming Series. She's a functionally asexual scientist! He's a gay librarian! They Fight Crime! They get married! They have kids!
 * Orson Scott Card seems to be a fan of this in general. He ends the Ender's Game series in Children Of The Mind with a double marriage that seems to serve little point but to pair up all the remaining single characters of young adult age, among them an embodied fragment of another character's psyche and the recently created biological avatar of the future-internet's artificial intelligence.
 * Nicely averted in Jennifer Crusie's Bet Me. Despite the main couple and many of the side characters hooking up,  remains with temporary boyfriends by the end of the book.
 * From The Wheel of Time
 * Depending on which version of the King Arthur myth you read, Sir Gareth either marries his Damsel in Distress Lyonesse or his Damsel Errant Lynette. Either way, his brother Sir Gaheris marries the other one.
 * Lampshaded in The King's Damosel by Vera Chapman, in which Lynette marries Gaheris but is in love with Gareth (since they've, you know, actually spent time together). Luckily, Gaheris is as uninterested in the marriage as she is.
 * Averted in Betsy Tacy. Multiple couples and pairings are suggested or named throughout the high school books, but only four of those couples ultimately marry. All other characters marry someone they met after high school.
 * Throughout Rachel Hawkins' Hex Hall series, Sophie has a Love Triangle going on with Archer Cross and Cal. Further complicating things is the fact that  Archer's ex-girlfriend Elodie is magically bound to Sophie.

Live Action TV

 * Ned's Declassified School Survival Guide: While Ned and Moze officially hook up, Ned's ex-girlfriend, Susie, and one of Moze's fanboys, Loomer, get back together.
 * Drake and Josh, "Playing The Field": When Drake and Tori get back together, Drake hooks her date up with his Operation: Jealousy date.
 * Firefly has Simon attempting to make a joke about this to Kaylee in "The Message." It does not go well.
 * In the final season of The Nanny, Niles (the Snarky Butler) and C.C. (the Evil Would-Be Love Interest) end years of antagonism by getting married.
 * Parodied/exaggerated in Friends. Ross’s doppelganger Russ, newly dumped by Rachel, is saying goodbye to the gang. Julie, the woman Ross broke up with to be with Rachel, turns up. Russ and Julie look into each other's eyes, and in mere seconds are completely in love.
 * Also in Friends, Joey comments to Phoebe that "Ross and Rachel are together, Chandler and Monica are getting married, maybe you and I should...". She replies that they do, "all in good time".
 * Joey actually averts this. By the end of the series, he's the only friend not in a serious relationship.
 * Lost: Jack and Kate get off the Island and hook up (for a while), leaving behind Kate's other love interest, Sawyer, and Jack's other love interest, Juliet. Sawyer and Juliet eventually get together, but it's a testament to the acting ability of Josh Holloway and Elizabeth Mitchell that the Sawyer/Juliet relationship comes out of nowhere (unless you'd been brushing up on this trope) and yet many viewers felt they were more convincing, more dramatic and way less annoying than the Jack/Kate relationship, which had been around from the pilot episode.
 * Parodied on an episode of the sitcom Working, where after a ban on inter-office relationships is lifted, everyone quickly pairs off in order to release the sexual tension that had been building. The Butt Monkey is too slow, and the only one left is a Little Old Lady.
 * The Doctor Who story The End of Time shows Martha Jones and Mickey Smith being married, even though Martha was previously (supposedly happily) engaged to someone else and their interaction during the show was minimal. Word of God states that her honeymoon mentioned in Torchwood was actually to Mickey, and both characters were initially intended to appear before Noel Clarke and Freema Agyeman were unavailable.
 * In Scrubs, after J.D. and Elliot get together for good, their exes Kim and Shaun also become a couple.
 * Earlier, Season 3's finale played with this by having Sean drive Danni (JD's girl of the season) home.
 * Spaced hints at this in the second series, with Mike and Marsha. While their interaction throughout the series is easily open to interpretation, their last scenes in the final episode give at least some evidence to a potential relationship.
 * Jossed by Word of God, as Mike has been revealed to be gay, thus explaining his Ho Yay with Tim.
 * Fans of Degrassi the Next Generation are fond of this, pairing (for instance) Emma with Jay so as not to interfere with Ellie/Sean. (Emma is paired with Sean. Ellie is not paired with Jay.) Similarly, practically all Spinner/Manny shipping is to stop anything from happening between Craig and Manny. Craig/Manny shippers are conversely fond of Jimmy/Ashley and Sean/Ashley, while Emma/Sean shippers are fond of Craig/Ellie.
 * In series example. At the end of Season 9, long standing couple Jay/Manny had their best friends (Spinner and Emma) get married. Some fans were not pleased by this. In that it Ruined FOREVER the chances of Emma/Sean and broke up fairly long lasting Spinner/Jane.
 * A better example would be Jimmy/Hazel. Spinner and Jay aren't exactly best buds. It's just that Jimmy was angry at Spinner for the whole paint and feathers incident. At the same time, Sean had lost his mind after killing Rick.
 * In The X-Files, Dogget and Reyes, the two agents that replace Mulder and Scully, are romantically involved during their one season onscreen. It would have been interesting to see where that relationship had gone, had the show's ratings not been so low and the show cancelled.
 * It was obvious from the onset that Reyes was meant to be Doggett's love interest. Chris Carter said that Doggett was not meant to replace Mulder or be a love interest for Scully. So it seems Reyes, while mostly being brought on to replace Scully on The X-Files, also had the added bonus of placating outraged MSR shippers.
 * Glee pairs Brittney and Artie as well as Sam and Mercedes for seemingly no other reason than this trope.
 * Some Castle fans view the Espositio/Lanie pairing this way, since Castle/Beckett is the Official Couple and Detective Ryan is engaged. However if you watch closely to first and second season episodes, Esposito is flirting with Lanie.
 * Lampshaded on Home Improvement: Tim points out Jill's attempts to Pair the Spares, and Jill responds, in an angry tone, "Because I want everyone to be as happy as we are."
 * In Our Day Out, two students of opposite sexes each have a crush on one-half of a teacher couple. One of the teacher couple encourages the students to get together, and they do.

Theater
""No sooner met, but they looked; no sooner looked, but they loved; no sooner loved, but they sighed; no sooner sighed, but they asked one another the reason; no sooner knew the reason but they sought the remedy." --Rosalind"
 * Taken to a science by Gilbert and Sullivan. They do this in nearly every one of their plays. In the final number, all the pairs are established, and the crowds pair off as well.
 * In The Sorcerer, they go so far as to pair somebody off with the local Notary, who doesn't even get a name.
 * Of particular note is Patience. Attempts to Pair the Spares are the basis of an entire musical number. No matter which way the couples are made, there is always one man left over.
 * The final lines of the show: "Each of us will wed the other, / Nobody be Bunthorne's bride!" Given that the operetta's titled Patience, or Bunthorne's Bride, this is a pretty major subversion.
 * Convincing a character that Pair the Spares really is the way to go and she'll be a lot happier that way is the basis of the entire finale of The Mikado, including the immortal lyric: "You've a very good bargain in me."
 * Parodied in The Pirate Movie, where Mabel, after being told she can't marry until her older sisters have married, freezes her dream and pairs everybody else off. Including, since there are more pirates than sisters, pairing two of the male pirates together.
 * Subverted in The Yeomen of the Guard, where everyone ends up with the wrong person, and poor Jack Point is left out to dry.
 * At the end of Ruddigore, Rose goes back to Robin, so Richard decides to marry one of the bridesmaids instead.
 * Ruddigore is probably the play that most rigorously enforces this trope—even the haunted portraits of the barons of Ruddigore get married (to more bridesmaids!) at the end.
 * This is incredibly awkward to act when you are involved in an amateur production composed of children aged between nine and fourteen. Even more awkward when the school has to stick together a chorus composed mostly of girls due to a lack of male enthusiasm.
 * In some shows the pairs aren't explicitly stated in the script, but that generally won't stop most theater companies from pairing people up anyway. There are only two pairings at the end of The Mikado: The romantic lead Yum-yum and Nanki-poo, and the plot obstacles Katisha and Ko-ko. But typical amateur productions also pair up most or all of the other leads, and the entire men's chorus of Gentlemen of Japan with the women's chorus of Schoolgirls, for the closing number.
 * Not really part of the story itself, but in adapting La Boheme into Rent, this is done. In Boheme, the musician Schaunard and the philosopher Colline are happily single secondary characters (and make plenty of wry comments about their friends Rodolfo and Marcello, and their relationships). Their analogues in RENT, Angel Schaunard and Collins, are a couple.
 * In Wicked, Galinda's attempt to pair off her Stalker with a Crush Boq with Nessa, Elphaba's unbalanced sister, proves one of the most disastrous on fictional record.
 * Oklahoma!! has Gertie Cummings, who flirts with Curly in the first scene, and Ali Hakim, the threat to the Beta Couple of Will and Ado Annie, married before the final scene by means of a Shotgun Wedding.
 * Directly invoked in the lyrics of the Act II Finale of Spamalot, where the male and female chorus members pair off for a big group wedding.
 * In Cole Porter's musical Anything Goes, the characters Hope and Billy knew they were a perfect match before the play opens, but after being apart for a while, Hope gets engaged to a stuck-up wealthy Englishman named Evelyn, and Billy is propositioned by his longtime friend, a sassy nightclub evangelist named Reno. In the end, Evelyn is revealed to have gypsy ancestry and be hiding a spontaneous wild side. He marries Reno, Billy marries Hope, and Billy's boss marries Hope's mother.
 * In Oscar Wilde's The Importance of Being Earnest, all the crazy hijinks due to all the "Bunburying" get sorted out and the young people are satisfied by the end. So of course, the PRIEST and the NANNY embrace passionately too.
 * He's not a priest, he's some sort of Protestant minister (probably Church of England) so it's completely fine for him to get married. Also, the two of them had been flirting very awkwardly (and without much success) throughout the play, so the finale was just gave them the extra nudge they needed to get together.
 * In Kander and Ebb's Musical, Curtains, after Bobby finds his love, Georgia, is back with her ex-husband, he starts a romance with Bambi, the last single female role.
 * Even William Shakespeare got into the act on occasion. In As You Like It, after Orlando's brother Oliver does a Heel Face Turn when Orlando saves his life, he hooks up with Rosalind's cousin and best friend Celia.


 * Also, to a lesser extent, in Measure for Measure.  and Isabella are paired off together, though Isabella had intentions of becoming a nun and he's obviously way too old for her. There is also Lucio, and Random Prostitute A, but Your Mileage May Vary about this one...
 * Subverted in Sheridan's The Rivals, in which all the major characters but two are already paired by the end as part of the story. This leads another character to suggest that spares Sir Lucius O'Trigger and Mrs. Malaprop pair up, but Sir Lucius responds with disdain.

Video Games

 * Fire Emblem: Genealogy of Holy War has Badass Bookworm Azel trying to woo over White Magician Girl Edin, while his childhood friend and Rebellious Princess Tiltyu chases after the Priest Claude. Depending on the players' actions, they may succeed their wooing. But should they fail... both of them can hook up together. And they're actually predestined, meaning they can be hooked up very easily due to game mechanics.
 * Since the first half of the game revolves around making sure that all your female characters are paired up with a husband, the gamer can actively engage in this trope if he/she realizes that they did not pair up somebody yet and all the "normal" options are taken.
 * Some of the Harvest Moon games (especially the Mineral Town ones) fall into this trope. After you've chosen your bride, your romantic rivals will often end up marrying their crushes (e.g. if you decide not to pursue Elli, then the Doctor gets her, and if you don't flirt with Ann, then she winds up with Cliff) a few weeks after you have your ceremony.
 * Subverted: If you don't choose Cliff for a certain event, he will leave for good and Ann will remain single.
 * If you show no interest in the human love interest (Ashley if you're male, Kaidan if you're female) in Mass Effect, they will show hints of mutual attraction.
 * Flame and Ember from Spyro: A Hero's Tail are almost always shipped together, despite the two never showing interest in each other, and Ember's crazy obsession with Spyro. This is mainly because Spyro gains a canon love interest, Cynder, in The Legend of Spyro reboot series, even though Flame and Ember don't exist in that continuity.
 * Note that Ember is canonically paired with Bandit the Armadillo.
 * In the remake of Lufia 2 Rise of the Sinistrals, Maxim's Unlucky Childhood Friend Tia gets together with Dekar immediately after Maxim and Selan's wedding.
 * In Mass Effect 3, if you did not romance either over the course of the game, they will have dialogue between one another that sounds incresingly flirty. Eventually
 * Mostly nonromantic example - in Hatoful Boyfriend, at the end of the Bad Boy's Love route, the birds who were most significant in each others' plotlines are shown together - brothers Sakuya and Yuuya, Foe Yay couple Kazuaki and Shuu (who have a relationship "outside normal standards of morality"), and Victorious Childhood Friend Ryouta with Hiyoko. San and Anghel, who barely interact, are shown together too, simply because they're both the two characters too weird to coexist happily with anyone else (Anghel is either Longing for Fictionland to the point of madness or a full-blown Talkative Loon with extremely vivid Hallucinations depending on interpretation; San is a throwback to before birds were fully uplifted and thus is The Ditz. The ending portrays them as compatible due to Anghel being too crazy to notice San's stupidity and San being too stupid to notice that Anghel is crazy.

Web Comics

 * In Boy Meets Boy, Skids vents his frustration about his unrequited feelings for Harley out on Tybalt, the ex-boyfriend of Mikhael, Harley's current boyfriend. To make things even more complicated, Tybalt has also tried to seduce Harley and initially views Skids' lingering attraction to him as an obstacle. Long story short, the two become close friends and share a kiss near the end of the strip's run.
 * In I Was Kidnapped by Lesbian Pirates from Outer Space, the artist parodies this by setting Alice and Dr. Wendy up on a date and.
 * Khaos Komix has an interesting aversion in which Mark and Amber, while dating one another, get their best friends to go on a double date with them. The twist is that Mark and Amber break up that very night to be with their respective 'spares' in the end.
 * The goal in the "Serious Business" story arc in the Insecticomics is to pair the spares. All of them, even the ones who weren't unpaired to begin with, and in as many combinations as possible.
 * In-story example, from Girl Genius: As the Heterodyne Boys have been Shrouded in Myth, since Bill married Lucrezia shortly before their disappearance, his brother Barry was given the stock character of “The High Priestess” for a love interest in most present day dramatizations of their adventures. As the Myth Arc unfolds, it hints at what (if not exactly who just yet) the original High Priestess was, and thus what sort of secrets they were after.
 * In-Universe that's the plan of Princess Xerxsephnia von Blitzengaard, who was somewhat obsessed with Gilgamesh Wulfenbach "since she was a child", and now faces the fact that Gil is obviously infatuated with Agatha. If her cousin Tarvek wins Agatha, Seffie will be close to Gil (as their clan's ambassador) and do her best to make sure he won't stay lonely for very long. She even defied the Grandmother for this, though if the plan works, their clan's matriarch presumably won't object much, as either is among the most powerful Mad Scientists around and should be considered "a good match". As Seffie put it, «I have always been destined for a political marriage. This is the one I want.»
 * Sonichu takes this to a major extreme. At first, the only pairing was the titular character and Rosechu. However, by issue 9, Episode 19, Chris has paired just about everyone of his creations with a girl and remedies the last one, Magi-Chan, in the next episode. He... just doesn't like anyone being alone.
 * Toward the end of Fans Book 5(the strip's original Grand Finale, before it was revived), Tim ends up married to Julia. In a conversation between Guthrie and Meighan, it is more or less revealed that Meighan had hired Julia(an old friend of hers from college) for the express purpose of setting her up with Tim.

Western Animation

 * Code Lyoko: While they don't hook up, Yumi's and Ulrich's Romantic False Leads, Sissi and William, have a heart-to-heart chat at the pool commiserating about their unrequited crushes, realizing they both desperately want the same thing: for these Just Friends to get over each other.
 * Sissi and Odd unknowingly dated online. Perfect plot wasted.
 * In Re Boot, Mouse was first brought in as a former flame to Bob, making Dot jealous. In Season 3, during their travels, Matrix and AndrAIa encounter Ray, who the former instantly pegs as a rival for her affections. Naturally, the two end up together.
 * Kim Possible: After the Kim and Ron hookup in The Movie, they started pairing spares. Bonnie got matched with Señor Senior Junior in a late Season 4 episode, and in the Graduation Grand Finale episode they paired Felix (and his cool wheelchair) with Zita Flores (who hadn't been seen for about 70 episodes), Drakken and Shego was implied during that finale and Word of God confirmed them as hooking up. A stand alone episode involving nerdy Cousin Larry also had an implication that he was going to get involved with a friend of his. This basically left only Monique and Wade as unattached, and probably only because of their age difference.
 * On The Simpsons, at the end of the episode parodying the Big Brothers institution, Homer's Little Brother and Bart's Big Brother seem to be left out in the cold... until Bart points out that they would both do well together.
 * Before Bart matches them up, they actually spend a few moments bemoaning their situation in a way that, if they were actually paying attention, would indicate that they were perfect for each other—and then cheerfully bid each other farewell.
 * Parodied in the episode "The Canine Mutiny", in which Bart obtains an extremely well-trained rough collie named Laddie, and gives up Santa's Little Helper, who ends up living with a lonely blind man. At the end, when Bart manages to get SLH back, Laddie shows up (now working as a police dog) and appears to take an instant liking to the blind man, making it look like we're in for a heartwarming "Pair The Spares" conclusion. Turns out, Laddie is merely fulfilling his duties as a sniffer dog...
 * A recent episode depicts Marge and Homer five years in the past, almost cheating on each other at the same time at the same motel. When they run into each other each tries to hide this fact, and Homer's almost-mistress winds up locked in a box with Marge's almost-lover. Back in the present, the two are happily married with a daughter.
 * In Tiny Toon Adventures episode "Prom-ise Her Anything" Fifi was Hamton's prom date. Mostly because they're both the third person in their 3 man teams, with Buster/Babs and Plucky/Shirley
 * In the most recent Scooby Doo show, Mystery Inc., Velma and Shaggy have apparently become a couple.
 * Futurama uses this to resolve.
 * Bebe developed a crush on Skeeter at some point during Doug. This may have been requited.
 * Daria's finale movie somewhat randomly had Upchuck get together with minor character / Ensemble Darkhorse Andrea. The "Future Alter Egos," though not firmly canon, go even farther by pairing Allison with Lindy. Sort of a Theme Pairing for morally ambiguous characters who showed up in the respective movies?

Real Life

 * In the wake of the wedding of Prince William and Kate Middleton, even the legitimate media is gleefully speculating about William's younger brother Prince Harry possibly getting together with Kate's younger sister Pippa Middleton, despite the fact that they're both seriously seeing other people.
