-> ''Once, all the mice agreed that life would be better if the cat wore a bell to warn of his coming--until a wise old mouse asked, "[[TropeNamer Who will bell the cat]]?"''[[note]]In RealLife, cats learn to stalk without ringing the bell, but the fable (and by extension, the general premise) hasn't died.[[/note]]

A group agrees that an action would lead to a very desirable result, until they realize [[DidntThinkThisThrough someone has to carry it out]]. (Often a third party, like the intended victim, has to point it out.)

This can range from the realization that it is a SenselessSacrifice that will fail and so not achieve the end, to TheHero or TheLeader refusing to harm the ReluctantMonster and putting it on the DirtyCoward to do it himself, [[HoldingOutForAHero at which point the coward melts off]]. It usually has to be ''one'' person who does it, sticking at the selection point, but being endangered ''en masse'' is also possible. Of course, in some shows the ButtMonkey always gets this kind of job (which usually means a CrowningMomentOfAwesome). This is also a common issue for TheBait.

Compare AndThenWhat. Contrast JustEatGilligan, where a simple action which would resolve the plot is not carried out because [[IdiotPlot no one thinks of it.]] Also contrast MoreHeroThanThou, LeastIsFirst and SomeoneHasToDie.

* In ''Film/{{Tombstone}}'', after Curley Bill kills the town marshall, Wyatt Earp knocks him out and orders him taken to jail. The other cowboys surround him in order to take Bill back, until Earp puts a gun to Ike Clanton's head. Earp admits that they'll get him in a rush, but not before he blows Clanton's head off, so Clanton tells the others to back down.
* This trope playing out is ultimately how the Joker's plan for the two ferries fails in ''Film/TheDarkKnight'', on both the civilian and prison boats. (On both boats, the passengers are provided with a detonator that would destroy the other ferry, and informed that if both ferries are still intact after a time limit, both will be blown up.) In the first case played straight: nobody is willing to actually be the one who ''pushes the button'' even after they take a vote that ends in favor of doing it. While on the other boat there's an inversion: a prisoner steps forward making a speech about being willing to do the hard but obvious course of action (implying he'll "bell the cat"), but [[spoiler:he simply tosses the remote overboard so it can't be used and goes back to praying with a group of prisoners]], giving his previous speech [[HeroicSacrifice a different implication]], and upon retrospect, [[WhatTheHellHero calling the cops out for not doing the right thing to begin with]].
--> "Give it to me, and I'll do what you should have did ten minutes ago."
* In ''WesternAnimation/AnAmericanTail'', all the mice at the rally[[note]]A ''wow-ee''? What's a wow-ee?[[/note]] agree that the cats must go, but when Gussie asks how to go about it, everyone goes mum. [[spoiler:Then Fievel tells her about the Giant Mouse of Minsk.]]

* OlderThanFeudalism: Literature/AesopsFables contains the "Mice in Council" fable listed above.
* In ''Discworld/TheLightFantastic'', a group of men from a mob approach Cohen the Barbarian and one of them tells him to surrender, as he says Cohen can't kill them all. Cohen replies, "Perhaps so, but '''you''' will be dead." The group suddenly decides that someone else can deal with Cohen.
** In ''Discworld/GuardsGuards'', a dragon has just become the monarch of Ankh-Morpork, and has demanded VirginSacrifice [[spoiler:because it's expected of a dragon]]. Virtually everyone present is willing murmur agreement with whatever brave idiot takes the moment to protest this policy. Unfortunately, to everyone's exasperation, no one present is brave or foolish enough to actually protest. Naturally, [[NeverMyFault everyone blames everyone else for this]].
** In another Pratchett work, the ''Literature/NomesTrilogy'', a PowderKegCrowd of nomes talk about getting revenge on humans by torturing a captive human. Grimma stops them by asking individuals suggesting tortures to do it themselves. "Well I didn't mean ''me''..."
* In Creator/RudyardKipling's ''Literature/TheJungleBook'', when the head wolf fails to take down the prey, the pack can take him on -- but, as he reminds them, it is his right that they come one by one.
* In Creator/TanithLee's ''Literature/TheDragonHoard'', Jasleth and other rowers hide to await the sea monster and attack it, but when it actually appears, they nervously offer each other the chance to do it.
* In Creator/SheriSTepper's ''Literature/SixMoonDance'', a GenderSwap results in the ladies suddenly deciding against a plan.
* In ''Wizard's First Rule'', first book of the ''Literature/SwordOfTruth'' series, a lynch mob comes for Zedd, accusing him of being an evil wizard who has to be killed before he destroys them all. Zedd points this trope out by noting that the mob would have to be ''extremely'' brave to come at him, considering all the terrible and deadly powers they seem to think he has. By the end of Zedd's little speech, most of them are profusely apologizing and begging to be let leave.
* In the Israeli short story collection ''[[https://he.wikipedia.org/wiki/%D7%A1%D7%99%D7%A4%D7%95%D7%A8%D7%99_%D7%90%D7%91%D7%95-%D7%A0%D7%99%D7%9E%D7%A8 Abu Nimer Stories]]'' (link in Hebrew), which may or [[BasedOnAGreatBigLie may not]] be a collection of folk stories told by [[TheStoryteller an old Arab from Jaffa]] to the compiler(/writer), features a variation of the story, in which a fox is the one who offers the plan in exchange for a reward, and when the mice ask how to hang the bell he claims it’s ‘just a technical detail’. When he asks for the reward, the mice point out a large [[BlessedAreTheCheesemakers chunk of delicious cheese]] on a shelf the fox can’t reach; when he asks how he’s supposed to reach it, they [[IronicEcho claim it’s ‘just a minor detail’]].

* Invoked in a BadassBoast in the ''Series/DoctorWho'' episode "The Pandorica Opens". The [[LegionOfDoom Legion of Every Species The Doctor Ever Fought]] is descending on the planet the Doctor's on. The Doctor gets on the radio and reminds them that he's always been able to take the respective species when they weren't working together. [[spoiler: Of course, what he doesn't know is that they're not there to ''kill'' him...]]
-->'''Doctor''': Look at me, [[IndyPloy no plan]], no backup, no weapons worth a damn. Oh, and something else I don't have: [[PunctuatedForEmphasis Any! Thing! To! Lose!]] So! If you're sitting up there in your silly little spaceships with all your silly little guns, and you've got any plans on taking the Pandorica, tonight, just remember ''who's standing in your way''. Remember every black day I ever stopped you. And then, ''AND THEN'', do the smart thing. ''[beat]'' Let ''someone else'' try first. ''[cue shot of all the spaceships flying away]''
** The Pandorica: [[spoiler:built to contain the most feared thing in all the Universe...and what did the Doctor just go to great lengths to remind everyone?]]
** It comes up in "Day of the Moon" when the Doctor, River and Rory show up to rescue Amy from the Silence.
--> '''Doctor:''' I know you're team players and everything, but River will definitely kill at least the first three of you--
--> '''River:''' Oh, the first seven, easy.
--> '''Doctor:''' Seven, really?
--> '''River:''' Mmm, eight for you, honey.
* This is a common trend in many seasons of ''Series/{{Survivor}}'', especially the later ones, and in later episodes; some players might want someone in a position of power gone, but nobody wants to lead the charge against them for fear of being targeted and voted off themselves. This is doubly true if the person in power has an immunity idol, which they could easily use as insurance if they anticipate a coup.
** Subverted in the Characters/SurvivorRedemptionIsland season, in that the alliance that formed to counter Russell Hantz and his "concubines" had no trouble finding a willing member to go out and act as the decoy.
* ''Series/GameOfThrones'' gives us a memory from Cercei Lannister, showing that EvenEvilHasLovedOnes. While she was in labour before giving birth to her son, Joffery, Cercei's brother Jaime (widely recognized as one of the greatest swordsmen in the kingdom) was informed he could not be in the room.
--> '''Cercei:''' He just smiled and asked who proposed to keep him out.
* Inverted in an episode of ''{{Series/Babylon 5}}''. Warships from several different alien races arrive, all demanding to take custody of [[NamesToRunAwayFromReallyFast Deathwalker]]. Ivanova buys time by getting the starship captains to argue with each other over who has first dibs.
** Played straight later, when B5 seccedes from Earth and a strike force is on route to bring the rebellious station back into line. As the station prepares to repell them, Ivanova volunteers to lead the fighter squadron, reasoning with Captain Sheridan that if they are to order their men to fire on their own, then one of them should be there with them.
** A cat gets belled almost every episode. One of the recurring themes of the show (deliberately, by WordOfGod) is that there are mice who bell cats. In the final confrontation with the Shadows, [[spoiler: the best way to lure them into a trap is to "let" them steal the trap's location from the wreckage of a defeated warship. Who will fight a known hopeless battle just so the enemy can pick over their corpse properly?]] The One gives the order, a ranger obeys it, the cat gets belled.
* ''Series/ThirdRockFromTheSun'':
-->'''Don''': But who's gonna do it?\\
'''Tommy''': I'll do it.\\
'''Don''': Could be dangerous.\\
'''Tommy''': [[VerbalBackspace Harry'll do it.]]

[[folder: Religion]]
* Many of {{Jesus}}'s teachings in the Bible operate in this way, often with his rivals trying to trap him into supporting an unpopular cause or betray a possible hypocrisy in his teachings, only for Jesus to then turn it back on them in this fashion. In one example, the Pharisees drag an adulterous woman before him and inform him that the law requires her to be stoned to death, intending to trap him out. Jesus responds with "[[ShamingTheMob let he who is without sin cast the first stone]]"; since, of course, everyone eagerly demanding the woman's death are themselves guilty of sins that just haven't been publicly exposed, everyone knows it, and to step up to be the first to throw stones would be to expose themselves as a {{hypocrite}} or worse, no one is willing to go first.

* MouseGuard, the game based on the comic of the same name, is an interesting play on this story. Mice patrol the forest, helping their fellow mouse citizens, fighting weasel bandits, and handling the enormous beasts that trample/invade their villages. So when someone asks who will bell the bear/moose/snake/owl, a member of the Mouse Guard steps forward and says, "Me."

* In ''VideoGame/DragonAgeII'', Sebastian tells Fenris that it's their duty to inform the Templars about "the maleficar" in Hawke's circle of friends. (Whether he means Anders or Merrill is unclear, though the former is more likely given their mutual animosity.) Fenris' response invokes this trope, as his response to Sebastian is basically "If you want to turn in Hawke's friends, be prepared to incur Hawke's wrath."

[[folder: Western Animation ]]

* [[WesternAnimation/LooneyTunes Merrie Melodies]]: "Bell Hoppy," which reverses and humorously twists and parodies this trope. Here, the members of the Loyal Order of Alley Cats Mousing and Chowder Club, who just refused to take Sylvester (in his hapless "giant mouse chaser" persona) as a member, want to bell "the largest mouse they can find" ... only here, it's the starving cats who hope to take advantage with their prey wearing the bell (so they can eat him, natch), instead of the other way around (mice hoping to avoid becoming prey to a hungry cat). Naturally, Hippety Hopper – the baby kangaroo that Sylvester forever confuses for a giant mouse – happens on the scene and the lisping "puddy tat" is drafted to place the bell around his neck. Predictably, no matter what he tries, he ends up wearing the bell and getting clobbered. But then Sylvester uses ''ch-ch-ch-chicanery'' to get the critter to bell ''himself,'' and it appears that Hippety's unknown-to-him fate has been sealed... except that the zookeeper catches the escaped kangaroo and places him in a truck to take him back to the zoo, and Hopper actually likes his new toy. The other cats leap into the street, waiting for their prey... and get run down by the truck!
* That wasn't the first Warners' cartoon about it either. In 1941, "Sniffles Bells the Cat" has a group of mice debating what to do about the resident cat; Sniffles suggests the bell idea and everyone agrees to it, especially Sniffles, who realizes too late that he's not only the one given the bell but has been locked outside the mousehole. He reacts to this about as well as expected, then does run into the cat and gets it belled in spite of himself. Of course in the last scene he regales the other mice about his bravado over said cat, with fingers firmly crossed behind his back.
* Even BugsBunny got into the act. In "Knighty Knight Bugs," the Knights of the Round Table are called upon to recover their beloved Singing Sword. Not surprisingly, they are all too scared to think about the task ("the Black Knight (YosemiteSam) has a fire-breathing dragon!"). In a case of TemptingFate, Bugs, dressed as a jester, enters and announces, "Only a fool..." And promptly gets called such by the king. Guess which [[ButtMonkey Butt Bunny]] gets drafted for the job (on pain of death, no less)?
* MGM's ''WesternAnimation/TomAndJerry'' uses this in "Little School Mouse". Teacher Jerry includes "Belling The Cat" in a survival lesson for Nibbles/Tuffy. It ends poorly for Jerry, but the little grey mouse manages to [[spoiler: get Tom to wear the bell simply through ThePowerOfFriendship.]]
* Simply how the plot for ''WesternAnimation/TheSmurfs'' episode "A Bell For Azrael" starts off: the Smurfs make a bell for Azrael, and they draw straws for who will be the one to bell the cat. As it turns out, Brainy gets the short straw. Fortunately, Brainy manages to get the bell on Azrael without sacrificing himself by having its string loop around his tail.

* Charles Blondin, after tightrope-walking across Niagara Falls, reputedly turned to the gathered crowd and asked then "Who thinks I could do that with a person on my back?" The crowd unanimously cheered at this idea, until he pointed to some poor fellow in the front row and said, "You sir! Hop on!"
* After the death of Pope Nicholas IV in 1292, the deliberating cardinals [[http://en.wikipedia.org/wiki/Papal_election,_1292%E2%80%931294 took over two years to choose a successor]]. A pious hermit named Pierro de Morrone sent the cardinals a letter warning that [[BoltOfDivineRetribution God would punish them]] if they didn't get the job done. They responded by electing ''him'' Pope, much to his dismay. After initially trying to refuse, he accepted the Papacy (as Celestine V), only to resign five months later.
