It's always this way: The team has just made the finals of the big tournament, or the FakeBand has a big gig around the corner. However, the star team member just wrenched his back and is out of the Big Game, or the lead singer has come down with laryngitis.

Cue panic as the group scrambles to find a replacement (and this trope usually has a scene where the group is calling someone with a last name beginning with the letter Z). Down to their last hope, they bring in the LoveInterest of one of the team members. She's the savior of their group...except she stinks...can't score to save her life, can't sing, can barely play tambourine. However, thanks to her [[DungeonmastersGirlfriend romantic arrangements]] and/or the fact that the team forfeits if they do, she can't be kicked out of the group.

The team trudges on, thinking they'll get creamed in the Big Game or the contest...and they either do, but have fun doing it anyway, or they win in spite of her (or even ''because'' of her, bringing [[AnAesop the Aesop]] with it).



[[folder: Anime and Manga ]]
* Subverted in ''Manga/RanmaOneHalf'': after Akane injures herself on the night before the [[MartialArtsAndCrafts Martial Arts Rhythmic Gymnastics]] tournament, she despairs at the thought of finding someone who "...[[SupernaturalMartialArts is good at martial arts]], [[SuddenlyAlwaysKnewThat knows gymnastics]], and [[MsFanservice looks good in a leotard]]" in such short notice. Everyone immediately shanghais [[MyKungFuIsStrongerThanYours Ranma]] into service.
* In the baseball episode of ''Anime/SamuraiChamploo'', all the members of the team quit before the big game against the Americans, so the ninja coach recruits the main characters. Mugen and Jin are the only useful ones however, as the other players are Fuu, an old man, a dog, and Fuu's [[RidiculouslyCuteCritter pet flying squirrel.]]
* In the Dark Tournament arc of ''Manga/YuYuHakusho'', circumstances leave both Team Urameshi and Team Toguro with only four of the required five members as they head into the finals, so each team's sponsor (Koenma and Sakyo, respectively) volunteers to fill the missing rank. Possibly {{subverted}}, as neither one are actually combatants, and both freely admit that they will run like hell rather than set foot in the ring.

[[folder: Film ]]
* ''Film/SpaceJam'': The toons are taken out one by one by one, until finally Michael Jordan's publicist is in the game. When he gets squashed, it looks like they'll have to forfeit...until the miraculous entrance of Bill Murray! Who just fills out the five on the floor as Michael stretches for the winning basket.
* Played with in ''Film/TheProducers'' (2005). When the star of SpringtimeForHitler has a broken leg, the director fills in at the last minute. He turns the show into a roaring success, when it was supposed to fail. Turns out the audience couldn't get enough of CampGay Hitler.
* In ''ShaolinSoccer'', the villainous soccer team named...wait for it...'''Team Evil''' have used their doping-enhanced strength to injure several of the players on the good-guys team - the game's nearly over, but they're short one goalie, and they have to forfeit if they can't find a replacement. Cue the hero's love-interest entering to demonstrate that [[MyKungFuIsStrongerThanYours her Kung Fu is stronger]], and win them the match.
* ''GetReadyToBeBoyzvoiced'': The boy band's frontman falls ill just before Boyzvoice are due to play at the Hit Awards, and is replaced at the last minute with an obsessive basement-dwelling fanboy who won a contest to hang out backstage with his favourite band. Despite a mimed performance with a stand-in for the group's most popular member, their Hit Award appearance cements their position as a europop sensation and catapults them to fame and fortune.
* In ''Film/DodgeballATrueUnderdogStory'', when three of the "Average Joes" team members go missing right before the final match (ironically, one of them was absent because he was called away to be a Hopeless Replacement in a completely different competition), the team's manager Owen is brought in to play in a last ditch effort to fill space.

[[folder: Live Action TV ]]
* On ''Series/FamilyTies'', Alex needs a third for a quiz bowl team, and is forced to use Mallory. He coaches her extensively and she ends up being the star of the team after Alex suffers stage fright.
* This was subverted in an episode of ''Film/{{Clueless}}'', during a big school basketball game when the star player is out. Friends Sean and Murray fill in as replacements, and happen to be really good and beat the other team.
* In ''HollysHeroes'', being short a player forced Holly to field the team's statistician on the basketball court, only for her to turn out to be a brilliant goal shooter (but terrible at the rest of the game). She was used a regular player for the rest of the series.
* ''{{Kirk}}'': The bowling team is in the finals, but their best bowler just threw her back out. In comes Kirk's main squeeze, who stinks...until she's given some reverse psychology by Kirk, and pulls out the victory for their team.
* In the ''Series/StarTrekDeepSpaceNine'' episode "Take Me Out to the Holosuite", after cutting him from the team earlier because of his lack of skill, Rom is brought on as a last-minute substitute by Captain Sisko after he himself gets booted from the game. Rom makes an accidental bunt that lets Nog score the Niners' only point.
* In ''{{Glee}}'', [[TheDitz Brittany]], of all people, is bribed into joining the [=McKinley=] academic decathlon team as an emergency replacement. As it turns out, she knows a ''lot'' about cat diseases, winning them the semi-finals almost singlehandedly.

* In the ''Radio/CabinPressure'' episode "Fitton", standby passenger Mr. Goddard arrives after the staff of MJN Air have given up on his showing up and after Martin has got spectacularly drunk. Douglas, who doesn't drink, is perfectly capable of doing all the flying, but they need a sober warm body in the captain's seat. [[CloudCuckoolander Arthur]] and Martin trade uniforms, and Arthur impersonates a pilot (poorly).


[[folder: Western Animation ]]

* Parodied on ''WesternAnimation/{{Futurama}}'', "Time Keeps On Slipping". Fry volunteers to sub in a basketball game so the team won't forfeit. The team is leading by a large margin and the game is nearly over, but Fry costs them the game anyway, and he doesn't understand how that happened (see episode title).
* A good decade or two before that, guess who did something similar in a short in the ''[[{{Peanuts}} The Charlie Brown and Snoopy Show]]''.
* Subverted (or inverted? Or just parodied?) in an episode of ''WesternAnimation/SouthPark'': The boys need to win a dance contest, and try to recruit Butters, who's [[InformedAbility a world class tapdancer.]] He refuses because he accidentally killed 15 people last time he danced, so instead they recruit a dancing duck. Then, in the climax, the ''duck'' is injured, and Butters subs in for him. [[spoiler:Let's just say he had a good reason for [[RefusalOfTheCall refusing the call]] the first go-round.]]
** Also inverted in an episode where the entire South Park Little League team is sick to death of playing baseball, and are trying their hardest to ''lose'' the final game, as the winning will keep playing other teams. They get the brilliant idea of getting Kyle's unbelievably unathletic cousin, but even that doesn't work out as it turns out the other team had the exact same feelings for the game, and were better at playing badly. [[spoiler: Fortunately, Stan's dad gets in a fight with another fan, which causes the South Park team to be disqualified.]]
* In ''WesternAnimation/TheLegendOfKorra'', [[TheHero Korra]] first joins the Fire Ferrets when their third member fails to show up and they have two minutes to come up with a replacement. Unfortunately, she has no idea of the rules of pro-bending and quickly commits multiple fouls. Even when settling for just not getting knocked out, she still has trouble until her airbending training kicks in and allows her to dodge long enough for her teammates to win it. By the next match she actually knows what she's doing and becomes a competent teammate.
* ''An Extremely Goofy Movie:'' In the final race, the Gammas succeed in launching PJ out of the arena, forcing Max to call on Goofy to replace him so that they don't forfeit.


[[folder: Real Life ]]

* After the death of BruceLee, many actors with similar physical appearances or names popped up in hopes of becoming "The Next Dragon." JackieChan was the most popular, due to his movies' content having nothing to do with Bruce Lee, but many at the time still considered him a hopeless replacement. It took some time before he was able to make those movies; that his earliest leading roles in China ''were'' direct attempts to make a formulaic "Bruce Lee movie", and that he ''was'' unable to duplicate the actor's intensity and (in-character) fury had a lot to do with it.
* Sid Vicious was a hopeless replacement for Glen Matlock, the original bass player for TheSexPistols.
