* Lots of comics have this to some degree, but the best example would have to be ''ComicBook/SpiderMan''. All of Peter Parker's girlfriends (except Deb Whitman) have dated other members of his supporting cast at various points. Sometimes multiple members of said supporting cast. ''WesternAnimation/SpiderManTheAnimatedSeries'' rectified this oversight by adding some WillTheyOrWontThey between Deb and Flash Thompson.

* ''Manga/MarmaladeBoy'': throughout High School, OfficialCouple Miki and Yuu go through relationships with much of the rest of the main cast before and after they initially date, before finally getting together officially.

* ''[[Series/{{Degrassi}} Degrassi the Next Generation]]''. See the picture above. Note that the prominent use of gay and bisexual characters, along with several [[CastHerd cast herds]] is almost enough to make the entire thing circle in on itself. We pray they never involve TimeTravel. [[Administrivia/RenamedTropes Was originally the]] TropeNamer.

* ''Manga/MarmaladeBoy'': throughout High School, OfficialCouple Miki and Yuu go through relationships with much of the rest of the main cast before and after they initially date, before fially getting together officially.

* ''Series/{{Popular}}'', though it was a high school show and perhaps a JustifiedTrope. That said, boy, Josh did sure get to make out with/boink what, all the female cast short of April Tuna?

%%* ''Series/BeverlyHills90210'': Both the original and new series have many examples of this.

* ''WesternAnimation/TotalDrama World Tour'': mostly consisting of Gwen, Duncan, Courtney, Alejandro, Heather, and possibly Tyler, Cody, and Sierra.

* At some colleges (even stereotypically unsocial and nerdy ones) this can hold disturbingly true. Even if there are no social cliques, there will be sexual cliques. If you make this graph with math majors, they'll call them [[DoubleEntendre clusters]].

* ''WesternAnimation/StarVsTheForcesOfEvil'': The show starts out with Marco with a longtime crush on Jackie, while Star has a RelationshipRevolvingDoor with her ex-boyfriend Tom and a crush on Oskar for the first two seasons, but is mostly just blissfully single. Star starts getting feelings for Marco in Season 2, making her jealous of Jackie, but Marco doesn't appear to reciprocate. But after Star confesses her crush during "Starcrushed" and goes back to Mewni, Marco's first date with Jackie ends up bombing because Jackie realizes he cares about Star more. Star gets back with a reformed Tom just as Marco realizes he does have feelings for Star, while also bonding with Kelly. Star and Marco end up kissing while stuck in a magical photo booth while Star is still with Tom and Marco is dating Kelly, but don't make anything official. After realizing their dance under the Blood Moon might be the cause of their feelings, Star and Marco undo this and get back with Tom and Kelly respectively, only for them to realize the feelings were real and get together near the finale. And this is just the confirmed canon ships -- there was also plenty of ShipTease for other relationships, like Tom/Marco, Marco/Heckapoo, Janna/Tom, Janna/Star, and so on.

* ''WesternAnimation/{{Archer}}'': There are, mathematically, twenty-one ways the seven main characters (Sterling, Lana, Malory, Cyril, Cheryl/Carol, Pam, and Krieger) could pair off; of these, a third have actually happened. Lana, Cyril, Pam, and Carol/Cheryl have ''each'' had ''half'' of the other six.
** Pam takes a while to get into the game though, during the first season or so her bemoaning the fact that nobody would sleep with her despite this trope was something of a RunningGag.
* ''WesternAnimation/TheSpectacularSpiderMan'': Basically all teens dated more than one person with the sole exception of [[NiceGuy Randy]] [[BetaCouple and]] [[AlphaBitch Sally]] and Hobie Brown, who remained single.
* ''WesternAnimation/TheLegendOfKorra'' has a mild example: Bolin tries to date Korra, but she rejects him because she's interested in Mako. Mako and Asami date, but break up in time for the Book One finale, establishing initial OfficialCouple Mako and Korra. Only for ''them'' to break up in the next book; afterwards, Mako and Asami have a brief fling that is quickly ruined when a semi-amnesiac Korra returns and kisses Mako, believing them to still be together. Mako doesn't mention that they broke up, destroying his chances with Asami, and to top it off, in the finale he and Korra break up for good. The entire mess serves as a great way for Korra and Asami to bond during Book Three, [[spoiler:and the GrandFinale of Book Four has ''them'' get together instead.]]

Pat was gay but now he's bi\\

* ''Webcomic/MenageA3'' andd its spin-off and sequel comics, ''Webcomic/StickyDillyBuns'', ''Webcomic/SandraOnTheRocks'' and ''Webcomic/PixieTrixComix'', being essentially one giant extended RoommateCom in SexComedy mode, inevitably demonstrates this trope when the relationships don't overlap enough for LoveDodecahedron to be in force instead.

The '''Dating Do Si Do''' is the tendency for a long running piece of fiction to recycle characters. In shows dealing with relationships especially, the tendency is that the longer the story goes on, the greater the likelihood that ''everyone'' will at some point have been in a relationship with (or at least slept with) everyone else. Well, usually not ''quite'' everyone, but still, the number of people having been in a relationship with other people is probably greater than could be expected under normal circumstances.

As can be noted, this is especially common in long-running series that still keeps a fairly regular cast.

* Played with in ''Series/{{Friends}}''. Almost all of the straight, non-incest pairings had a ShipTease, though most were PlayedForLaughs, and almost all the characters have kissed each other. But only three pairs (Ross/Rachel, Monica/Chandler and Joey/Rachel) were treated seriously and actually happened. Given the show ran for ten years, the writers did pretty well at ''not'' having the characters constantly date each other.

* This is mostly averted in the ''Series/NoahsArc'' series, but played very straight in the movie with lot of sexual crossovers between [[spoiler:Noah, Wade, Baby Gat, Chance, Ricky, Brandon, and Eddie (basically all the main characters except Alex)]].

* ''Series/{{Angel}},'' like ''Series/{{Buffy|the Vampire Slayer}},'' is full of this. Cordelia was in love with Angel, [[{{Squick}} slept with his son]], and had some {{UST}} with Wesley back in their Buffy days. Fred had a crush on Angel, and dated Gunn and then Wesley (who had been sleeping with Lilah). Darla was Angel's sire and his lover for 200 years; Lindsey was briefly infatuated with Darla (possibly as a transference of his [[HoYay obsession with Angel]]), and was later a couple with Eve, who slept with Angel. Angel and Spike were both in love with Buffy, and both had been involved with Drusilla, [[HoYay and then there was that one time...]] When a new person asks if they have a chart, Gunn responds "In the files. I'll get it for you later."

* Addressed in ''Series/LastManStanding''. Kristin and Kyle dated during the first season, [[AmicableExes breaking up amicably]] at the end. After some progressive ShipTease, Kristin's sister Mandy started dating Kyle. Unusual for the trope, [[EveryoneCanSeeIt Mandy has to admit to herself]] that she likes Kyle and, from there, goes to Kristin for permission to pursue him. Kristin is more worried about Kyle than Mandy, as he is a NiceGuy and she is know to be a big flirt. While by and large it all works out, tension still flares up from time to time because of that history.
* On ''PetticoatJunction'' Steve dated the eldest Bradley sister, Billie Jo, for a while, but later as they drifted apart, he fell in love with her baby sister Betty Jo. Naturally their mother was a little upset about this development. To his credit he eventually married her.
* Throughout its eight-year run,''Series/TheVampireDiaries'' was the absolute master of this trope, despite starting off with one solid OfficialCouple, Stefan/Elena. You can pick any two characters of the opposite sex from the main and recurring cast, and there's a pretty good chance they've been romantically linked at some point. It gets especially bad in later seasons, where the show seems to [[PairTheSpares pair up any two people who are both single at the same time]], regardless of whether or not they've ever shown interest in each other before that season. The most egregious examples of romantic musical chairs among the main cast on this show include:

* ''WesternAnimation/{{Archer}}'': There are, mathematically, twenty-one ways the seven main characters (Sterling, Lana, Malory, Cyril, Cheryl/Carol, Pam, and Krieger) could pair off; of these, a third have actually happened. Lana, Cyril, Pam and Carol/Cheryl have ''each'' had ''half'' of the other six.

* ''Series/BuffyTheVampireSlayer''. Name any two characters ([[HoYay including characters of the same sex]]), and they'll either have been {{canon}} at some point or have a (sometimes very small, but still there) {{fanfic}} following.
** Lampshaded in the final season: "Is there anyone here that hasn't slept together?" [[note]]Well, Xander and Buffy haven't, but not for lack of trying on Xander's part.[[/note]] [[HoYay/BuffyTheVampireSlayer And Xander and Spike (who shared a one-room basement apartment for several months) just stare at each other...]]

* ''Series/{{Angel}},'' like ''Series/{{Buffy|the Vampire Slayer}},'' is full of this. Cordelia was in love with Angel, [[{{Squick}} slept with his son]], and had some {{UST}} with Wesley back in their Buffy days. Fred had a crush on Angel, and dated Gunn and then Wesley (who had been sleeping with Lilah). Darla was Angel's sire and his lover for 200 years; Lindsey was briefly infatuated with Darla (possibly as a transference of his [[HoYay obsession with Angel]]), and was later a couple with Eve, who slept with Angel. Angel and Spike were both in love with Buffy, and both had been involved with Drusilla, [[HoYay and then there was that one time...]]
** When a new person asks if they have a chart, Gunn responds "In the files. I'll get it for you later."

* ''Series/{{Glee}}'': Let's see... the show explored Finn/Quinn, Finn/Rachel, Rachel/Will, Puck/Rachel, Puck/Quinn, Puck/Mercedes, Rachel/Jesse, Puck/Santana, Brittany/Santana, Finn/Santana, Kurt/Brittany, Terri/Will, Emma/Will, Emma/Ken, Will/Shelby, Quinn/Sam, Artie/Tina, Mike/Tina, Sam/Quinn, Artie/Brittany, Emma/Carl, [[OverlyLongGag Will/Holly, Rachel/Blaine, Sam/Santana]] [[spoiler: Kurt/Blaine, Santana/Karofsky, Sam/Mercedes]]. All in the first two seasons. Lampshaded more than once by Emma.

* In ''Series/TheMagicians2016'', just in the first season we get Quentin and Alice in a relationship as well as Penny and Kady, plus Quentin has a three-way with Margo and Eliot and as revenge, Alice sleeps with Penny. Later seasons give us AlternateTimeline Penny and Julia, Margo and Josh, and [[spoiler: Quentin and Eliot have feelings but Eliot rejects him before Quentin's death.]]

* ''WesternAnimation/TheSpectacularSpiderMan'' - basically all teens dated more than one person with the sole exception of [[NiceGuy Randy]] [[BetaCouple and]] [[AlphaBitch Sally]] and Hobie Brown, who remained single.

* ''Series/{{Bones}}'': Angela and Hodgins dated, then Angela dated Wendell then she dated Hodgins again. Cam dated Booth (twice), who then eventually dated Bones. Cam eventually went on to date Arastoo. Off in their own little corner is Daisy and Sweets who dated for quite a long time on and off. Sweets dated Jessica Warrwn for a bit, then reunited with Daisy before his season 9 death. Jessica later dated Aubrey.

Let's see... the show explored Finn/Quinn, Finn/Rachel, Rachel/Will, Puck/Rachel, Puck/Quinn, Puck/Mercedes, Rachel/Jesse, Puck/Santana, Brittany/Santana, Finn/Santana, Kurt/Brittany, Terri/Will, Emma/Will, Emma/Ken, Will/Shelby, Quinn/Sam, Artie/Tina, Mike/Tina, Sam/Quinn, Artie/Brittany, Emma/Carl, [[OverlyLongGag Will/Holly, Rachel/Blaine, Sam/Santana]] [[spoiler: Kurt/Blaine, Santana/Karofsky, Sam/Mercedes]].

* In ''Series/{{Coupling}}'', Susan dated Jeff, Patrick, and Steve; Steve dated Susan and Jane; and Patrick has been involved with Susan, Jane, AND Sally.

* ''WesternAnimation/TheLegendOfKorra'' has a mild example: Mako and Asami date, but break up in time for the Book One finale, establishing initial OfficialCouple Mako and Korra.
