** He acquires Piper Chat from Dinesh because Gavin wanted access to chat logs in order to spy on Jack Barker. In his haste, Gavin doesn't realize that he also inherited the under-age users and pedophiles that made Dinesh want to part with Piper Chat in the first place. Once the board realizes that they just bought a system that caters to such scum, they finally fire Gavin and replace him with Jack.

* In the ''Series/StarTrekTheNextGeneration'' two-parter ''The Best of Both Worlds'', both the Borg and the crew of the ''Enterprise'' do this to each other. The Borg use Picard's knowledge of Starfleet tactics to utterly defeat the fleet of ships that meet them at Wolf 359 while the crew of the ''Enterprise'' use a [[ChekovsLecture plan to defeat the Borg]] to trick them so they can save Picard.

----
* The Huntsman from ''Series/TheTenthKingdom''. Earlier in the miniseries, we are told that his magic weapon is a crossbow that, when fired, shoots bolts that will not stop until they hit the heart of a living being. So quite naturally, during the climax when he and Wolf are struggling over the weapon and it is accidentally fired upwards through the skylight, the rule of KarmicDeath (as well as the law of gravity) dictates the arrow comes right back down and stabs the Huntsman in the heart from behind.
* On Creator/SpikeTV's ''Series/OneThousandWaysToDie'', a pair of dimwitted terrorists were blown up by their own bomb when they forgot about daylight savings time while setting the device's GPS-based timer.
* In an episode of ''Series/TheAdventuresOfSuperboy'', a demon turns Loretta York into Yellow Peri, a powerful witch who wreaks havoc. When Superboy confronts them, Yellow Peri sets a photo of him on fire. Like a voodoo doll, this causes him to burst into flames, falling to the floor and screaming in agony. The demon laughs and mocks him. Angrily, Superboy blasts him with heat vision, but it has no effect. The demon [[VillainBall smugly boasts that only magic can hurt him]], and Superboy immediately grabs him, causing the fire to spread to him and reduce him to ashes. Fortunately, [[NoOntologicalInertia with him gone, his curses wear off]], Superboy is healed, and Yellow Peri reverts to Lorretta York.
* In the ''Series/AgentsOfSHIELD'' episode [[Recap/AgentsOfSHIELDS2E6FracturedHouse "Fractured House"]], Comicbook/{{HYDRA}} goon Marcus Scarlotti uses a combat knife attached to a chain (a MythologyGag, as his comic counterpart is Comicbook/IronMan villain [[WhipItGood Whiplash]]) to fight Agent May. Firstly, May manages to turn the fight in her favour when Scarlotti gets the combat knife stuck in a wall, and later uses the chain to restrain him while she beats him unconscious. Also in the episode, Scarlotti's team have been killing people with splinter bombs, devices adapted from ImportedAlienPhlebotinum that [[NoBodyLeftBehind disintergrate anyone it hits]]. When one of them throws a splinter bomb at [[Comicbook/{{Mockingbird}} Bobbi]], Hunter saves her by throwing another member of Scarlotti's team into the bomb's path.
** In the episode [[Recap/AgentsOfSHIELDS2E5AHenInTheWolfHouse "A Hen in the Wolf House"]], Comicbook/{{SHIELD}} implants Raina with a tracker, hoping that she'll lead them to Comicbook/{{HYDRA}} head Daniel Whitehall.. In the episode [[Recap/AgentsOfSHIELDS2E9YeWhoEnterHere "Ye Who Enter Here"]], HYDRA learn about the tracker, and use it to track down the [[CoolPlane Bus]], allowing them to recapture Raina, kidnap [[Comicbook/DaisyJohnson Skye]], and attempt to shoot down the Bus for good measure.
* In season 4 of ''Series/ArrestedDevelopment'' Gob [[spoiler:plots to get revenge on his rival, Tony Wonder. First he says he's going to make Tony fall in love with him and then break his heart; when he learns that Tony's faking being gay for publicity he decides to ruin his reputation by tricking him into having straight sex on camera. ''Both'' plans rebound on him. He's tricked into having sex with Tony, on tape - just as he becomes President of the Bluth company and is warned to avoid any scandals - and in his [[IHaveThisFriend completely hypothetical situation]] to Michael afterwards he implies he's actually fallen in love, only to later get a voicemail revealing Tony's roofied himself to remove the memory of the previous night.]]
* The inventor of the Cybernauts on ''Series/TheAvengers'' gets killed by his own invention, as does his brother who tries to follow in his footsteps.
* ''Series/BabylonFive'': The Soul Hunter in the first season is killed by the very machine he intended to use to collect Delenn's soul.
* ''Series/{{Banshee}}'' has a literal example. During the shootout in the season one finale, a group of Ukrainian gangsters try to use a rocket propelled grenade to kill the good guys. However, a lucky shot kills the guy carrying the rocket launcher and he squeezes the trigger while the rocket is pointed at a nearby wall. The explosion kills the other gangsters.
* In one episode of the new ''{{Series/Battlestar Galactica|2003}}'', in Season 2, a big Cylon Raider fleet fleet is disabled by a Cylon Logic Bomb, which they previously planted on the ''Galactica''.
* On ''Series/{{Baywatch}}'', Stephanie is taken prisoner by an escaped criminal. Hiding in the back of her truck, he orders her to drive off the beach. When Mitch radios Stephanie to tell her to return to headquarters, Stephanie starts to say "I have a code--", but the man cuts her off, knowing full well that she could be naming a code that alerts Mitch to her situation. Instead, the man orders her to tell Mitch that she has found a lost child and is driving him around to find his parents. But as this violates lifeguard policy (which is to take the child back to headquarters), it ends up having the very result the man was trying to avoid--Mitch instantly realizes Stephanie's in trouble and sends the cops after her.
* In the final episode of ''Series/{{Blackadder}} II'', Ludwig the Indestructible prides himself on being a MasterOfDisguise, and plans to use this, and the knowledge that Nursie always goes to fancy dress parties as a cow, to infiltrate Queen Elizabeth's court. Unfortunately, his pride in his disguises means he makes the mistake of disguising himself as a cow, rather than as a mad old woman with an udder fixation.
* On ''Series/TheBlacklist'', the titular villain from "The Stewmaker" [[spoiler:specializes in using chemicals to dissolve the bodies of people killed by a drug cartel. Reddington tracks him down after he kidnaps Elizabeth and kills him by pushing him into his own tub of chemicals.]]
* On ''Series/{{Blossom}}'', the titular character is assaulted by a date when she won't sleep with him. She's reluctant to press charges -- until he threatens her. Her anger spurs to go the police.
* In the ''Series/{{Bones}}'' episode "The Bullet in the Braincase", a sniper who has been using the names of other snipers in order to purchase supplies (and sticking them with the bills) is located when Booth discovers a piece of land bought using his name. When Booth confronts him, the sniper taunts him to jump the fence and enter the property without a warrant. Booth jumps the fence and points out he doesn't need a warrant; after all, the property belongs to ''Seeley Booth''. Cue the OhCrap look and the suspect running away.
* This happens a couple of times in the ''Series/BreakingBad'' finale. [[spoiler:Jesse, having been held captive for months by Todd and Jack, strangles Todd with his handcuffs and breaks his neck. Walt catches a bullet from the machine gun he set up.]]
* Obligatory examples from ''Series/BuffyTheVampireSlayer'' and ''Series/{{Angel}}'':
** Non-death example: In the sixth-season episode "Older and Far Away", Dawn makes a wish to the vengeance demon Halfrek that everybody would spend more time with her. Halfrek makes the dream come true by magically making it impossible for any of the guests at Buffy's birthday party to leave the house. She then comes and taunts them... until she realizes that ''she'' can't escape the house, either, and reluctantly reverses the spell.
** Another non-death example: [[BigBad The First Evil]] attempts to drive Angel to kill Buffy using the same {{mind rap|e}}ing tactics he himself used to great effect. It's happy with him being DrivenToSuicide however.
** Death example: Maggie Walsh is killed by her own creation that she was planning to sic on the heroes.
** Happens to Angel, in every sense of the word. Buffy runs him through with a replica of his own blessed sword, which in turns sucks him through his own hell portal. Putting a damper on this irony is the knowledge that Angel suffers the fate reserved for Angelus, because he regained his soul moments beforehand and that brief vulnerability may well have been what allowed Buffy's victory.
** When Dark Willow catches up to Warren, she begins by torturing him with the very bullet he used to shoot Buffy.
** Giles uses a spell from Roden's spellbook to kill him.
** Buffy puts Faith in a coma by stabbing her in the gut with her own knife.
** Non-death example: After successfully {{blackmail}}ing Angel into springing AxeCrazy HeManWomanHater Billy Blim from a PrisonDimension, Lilah's manipulations come back and bite her in the ass when Billy "[[UngratefulBastard thanks]]" her by first giving the credit to her [[TheRival rival]] Gavin and then [[HatePlague inducing]] him to beat the ever-loving shit out of her while he walks away with a PsychoticSmirk on his face, leading to Lilah [[EnemyMine helping]] Angel Investigations take him out.
* ''Series/ChicagoJustice'': A convicted serial killer tries to get his conviction for murder overturned near the end of "Double Helix" on the basis that someone else confessed under oath to the same crime. However, he was given immunity for other murders based on being completely honest, revealing where the victims' bodies were so their families could get closure. Therefore his admitting he lied violates it, and with his confession to those murders there's more than enough evidence for a conviction. He's remanded to prison and will be extradited into Indiana, where four of the murders occurred. They also have the death sentence.
* In ''Series/TheCloser'' episode "Tijuana Brass", a corrupt Mexican cop looking for an accused murderer (who plans to testify against the drug cartel the cop works for) has the word spread among locked up convicts that whoever kills the guy he's looking for will get a big reward. After his corruption is ultimately revealed and the protagonists arrest him, his former coworkers book him under the name of the guy he had put the hit on, which results in him being murdered in prison.
* An episode of ''Series/ColdCase'' featured a villain who would abduct women and imprison them in a windowless cell for months in order to break their spirit. Once this was achieved, he would [[LockedUpAndLeftBehind leave them there to starve to death]]. However, he stashes his latest victim within hearing distance of a church that rings its bells every Sunday. With this, the woman is able to keep track of the days and retain her sanity. Her refusal to snap rattles him so much that he finally makes a mistake that gets him arrested. To top it off, at the episode's end, we see him being tossed into a cell very much like the one he'd barricaded his victims in -- and he's claustrophobic.
** In another episode, the villain, who had been correctly identified as the prime suspect when the case was still hot, framed someone else for the murder and went to the police himself to get the case reopened, in the hopes of getting the other guy arrested and himself cleared. Needless to say, his doing this backfired.
** Still another had a particularly loathsome killer [[ForcedToWatch forcing his little niece]] to watch the murder to "teach her a lesson." Guess whose testimony turns out to be just the evidence the cops need to put him away?
* On the ''Series/{{Columbo}}'' episode "Double Exposure" the villain (Doctor Kepper played by Robert Culp) incites the victim to go out for a drink using subliminal images of a cold drink during a movie showing. Columbo, in order to reveal him, inserts various subliminal images of the office of the Culp-rit (pun intended) in another movie in order to entice him to retrieve the murder weapon and catch him red handed. It works.
* ''Series/{{Community}}'':
** In the episode "[[Recap/CommunityS1E08HomeEconomics Home Economics]]" this ends up happening to Vaughn. His usual method of revenge for people who piss him off is to write songs with [[CreatorBreakdown rather passive-aggressively spiteful lyrics]] in which he denounces them as a 'B'. Unfortunately for him, he gets a response song written about him in TheTag, which he apparently did not anticipate.
** In a Season 6 episode, Britta gives her convoluted explanation about how she ''thinks'' the phrase "hoisted by your own petard" originated.
-->'''Britta''': [[IThoughtItMeant I guess I just assumed]] that in the old days a petard was a special outfit like a leotard, with a lot of fancy buckles and loops on it, and that rich people would wear them when they were feeling especially smug, but then poor people would tie a rope through one of the loops, and hoist them up a pole and then let them dangle there as punishment for being cocky.\\
'''Jeff''': Never look it up. Your explanation is way better.
** In [[Recap/CommunityS6E11ModernEspionage Modern Espionage]] the enemy paintballer sets up a bunch of mannequins as decoys, only to get so involved in his NotSoDifferent speech that he mistakes his opponents for them and walks out into the open.
* The ''Series/CriminalMinds'' episode "Paradise" featured a killer who would murder guests at his hotel, place their bodies in their cars, and place the cars in a blind intersection nearby so they would be hit by trucks and thus [[MakeItLookLikeAnAccident make the deaths look accidental]]. At the episode's climax he seems to have eluded the FBI, only to realize too late that he's run into the same intersection and is promptly mowed down by a truck himself.
* One episode of ''Series/{{CSI}}'' featured a woman and her father who co-owned a construction company and wanted to end the marriage to the woman's husband without getting a divorce, since Nevada divorce law would give the husband half of her shares in the company. They try to frame him for attempted murder, since Nevada law also requires that criminals not profit from their misdeeds, which would have meant the husband wouldn't get anything belonging to his wife. The scheme backfires horrifically when the [=CSIs=] uncover the woman and her father's plan and charge them with conspiracy, and it's implied that, under the very same law they tried to use to deprive the husband of any part of the construction company, he's going to end up owning the whole thing.
** Meanwhile, in [[Series/CSIMiami Miami]], a wife uses the fact that she's part of a set of triplets to set up what seems to be an airtight alibi for herself (and thus, all of them) for her husband's murder. Except it turns out that the husband has been using a body double because of his high profile job, and the body double was the one who died.
* In the Season 7 episode of ''Series/CurbYourEnthusiasm'' titled "The Black Swan", Larry tells Marty that introductions are a pointless and unnecessary social convention. Later, when Marty didn't introduce the Stonemason as Larry was calling him an asshole, Marty reminded him of his own policy regarding introductions. Larry responds "So I'm hoisted on my petard."
** Larry David is late for a dinner because he's behind someone who takes a long time at a doctor's appointment, so he tells the doctor that patients should be admitted according to their appointment time. Later, he races to sign in at the doctor ahead of someone, but ends up going behind her because of the new policy, which goes with what David had ordered.
* ''Series/DadsArmy'': In order to clear the rubble from a bomb-damaged pumping station, a process which will be very dangerous for the two people at the front, Captain Mainwaring puts pieces of paper in his hat and marks two with crosses to indicate who will be at the lead. When it comes to Private Frazer's turn, Warden Hodges rudely pushes him aside and takes a piece of paper instead. So of course, Hodges gets one with a cross on it.
-->'''Frazer:''' What a pity; I was going to take that one.
* ''Series/DeadLikeMe'': In a non-villainous example, a flashback reveals that Roxy invented legwarmers and was strangled to death with her own invention by her jealous friend.



* On ''Series/SiliconValley'' Hooli CEO Gavin hits this time and again as his every effort to make a name for himself blows up in his face thanks to his own work.
** He boasts of how Nucleus will offer the greatest live stream of a UFC event ever seen. However, because of his terrifying presence, no one on his team has the courage to tell him the program won't be ready for weeks or months and the live stream is a disaster of glitches.
** Gavin promotes Big Head to a key position on the assumption it will help his fight against Pied Piper. However, Big Head is basically a moron who drives the actually competent division head (ticked over being passed over) away. Also, when Nucleus fails, Gavin realizes Big Head has been wasting company time and resources on a potato cannon and has nothing to offer that can be built in less than 30 years.
** Realizing he needs a scapegoat, Gavin talks that division head into coming back, promising to give him full control over the project. The man takes one look at the Nucleus code, realizes how unsalvagable it is and literally races away from the company. Reporting this, Gavin's lawyers (unaware of the truth) think this is a good thing as now "the whole world will know you and you alone are responsible for Nucleus."
** Gavin thinks he's got the perfect ammo against Pied Piper by revealing Hooli has a non-compete clause in employee contracts which means he owns what they came up with while working for Hooli. Sadly, he's neglected to remember that non-compete clauses are illegal in California which means that ''every'' Hooli employee is freed of their contract and the company owns ''nothing'' they came up with. Needless to say, the board is not happy with this.
** He illegally alters Hooli software to automatically delete any news that speaks bad about them...only to have a reporter break the story first and has Gavin ripped on censorship.
** Gavin buys a company to get control of Pied Piper's work...which just means there's a concrete point of price on the work Pied Piper made.
** When it becomes clear Gavin has been covering up how Nucleus never worked amid all his other blunders, the board finally relieves him as CEO. They can't fire him because of his contract so they just "transfer" him to another department...which ends up on the roof of the building with all the other guys Gavin has "transferred" over botched projects in the past.
* In the Season 7 episode of ''Series/CurbYourEnthusiasm'' titled "The Black Swan," Larry tells Marty that introductions are a pointless and unnecessary social convention. Later, when Marty didn't introduce the Stonemason as Larry was calling him an asshole, Marty reminded him of his own policy regarding introductions. Larry responds "So I'm hoisted on my petard."
** Larry David is late for a dinner because he's behind someone who takes a long time at a doctor's appointment, so he tells the doctor that patients should be admitted according to their appointment time. Later, he races to sign in at the doctor ahead of someone, but ends up going behind her because of the new policy, which goes with what David had ordered.
* ''Henry Danger'': Lampshaded in the pilot by [[LargeHam the Toddler]] as he sinks into his own ball pit. He's also blown up by his own bomb underneath the plastic balls too.
* The team of ''Series/{{Leverage}}'' were experts at this. Indeed, the DVD commentaries openly say how they use this.
** In "The Miracle Job" Parker has the idea to use the mark's own want of good publicity to take him down.
** One example in the episode "The 15 Minutes Job" not only do they bring a crisis PR consultant down using his own business methods, they also set him up for a drunk driving accident to make up for an earlier incident in which he'd set someone else up for a drunk driving accident in which he WAS driving.
** In "The Snow Job," a family specialize in bilking people out of their homes. The team set up a con that gets them control of the company and the father arrested for fraud. They then inform the elder son that because he listed the family's home as a company asset to avoid taxes, they now own it and force him and his brother out.
* In the ''Series/StargateAtlantis'' episode "The Tower", the villain dies due to a scratch from his own poisoned dagger. It is likely that this is a deliberate reference to the above-mentioned work of Creator/WilliamShakespeare, where Claudius and Laertes are both done in by the very poison they had conspired to kill Hamlet with. (Well, Claudius also gets ''stabbed'' a little bit. And, in one notable adaptation, [[FallingChandelierOfDoom hit by a chandelier]].)
* The Huntsman from ''Series/TheTenthKingdom.'' Earlier in the miniseries, we are told that his magic weapon is a crossbow that, when fired, shoots bolts that will not stop until they hit the heart of a living being. So quite naturally, during the climax when he and Wolf are struggling over the weapon and it is accidentally fired upwards through the skylight, the rule of KarmicDeath (as well as the law of gravity) dictates the arrow comes right back down and stabs the Huntsman in the heart from behind.
* In ''Series/{{Primeval}}'', Oliver Leek amasses a mind-controlled army of vicious predators from the future in a bid to obtain power. This royally screws up when the mind-control device breaks, and the predators kill him.
** Similarly, the woman who had raised a sabre-toothed tiger from a cub that she found is killed by it at the end.
* In the GrandFinale of ''Series/StarTrekVoyager'', the Borg Queen is tricked into assimilating Future-Janeway, causing her to contract a nanovirus (ten years in the making and about seventeen ahead of its time), killing her... [[DeathIsCheap again]].
** In the earlier two-parter "Year of Hell", the BigBad uses a ship that has the power to RetGone anything. Janeway's HeroicSacrifice causes the ship to target ''itself'' and everything that happened in the episode is undone. Oddly enough, this actually gives the BigBad a ''happy'' ending -- he had unwittingly wiped out his own homeworld and family when he used the ship during a war. With the ship gone from the timeline, the life he lost had been restored. [[spoiler: [[StableTimeLoop Though he is once again working on temporal calculations]]]].
* In the ''Series/StarTrekDeepSpaceNine'' episode "Civil Defence", the crew accidentally triggers an automated defense program left behind by the station's previous commander, Gul Dukat. After the crew's failure to circumvent the program triggers the station's self destruct, Dukat himself shows up and offers to save them if they give his people massive diplomatic concessions. He then attempts to beam off the station to let the crew mull his offer over, only to discover that one of his superior officers installed a similar program in case he ever tried to leave the station after triggering the self-destruct, an act that the superior officer considered to be Dukat abandoning his post. The program prevents Dukat from leaving the station and prevents him from using his access codes to stop the self destruct.
** In "The Die is Cast", the Obsidian Order and the Tal Shiar, the Cardassian and Romulan SecretPolice organizations respectively, launch a preemptive strike against the homeworld of the Founders, the Dominion's leaders. Except that they realize the planet was deserted, with a probe delivering false sensor readings, [[CurbStompBattle leading to a massive ambush by a Jem'Hadar fleet]]. Years earlier, in the ''Series/StarTrekTheNextGeneration'' episode "Chain of Command", the Cardassians also used this ploy to lure Captain Picard into a trap to be captured.
* The villain wasn't killed in the ''Series/DoctorWho'' episode "Dalek", but Henry van Staten surely paved the way for his eventual fate. His policy of using torture on his alien captive caused said alien to go on a murdering rampage when it finally got loose, and his fondness for wiping people's memories and dropping them off in a town starting with the same letter as their last name got turned around on him by his newly appointed [[TheStarscream second-in-command]].
-->'''Goddard:''' And by tonight, Henry Van Statten will be a homeless, brainless junkie living on the streets of San Diego, Seattle, Sacramento... Someplace beginning with S.
** In ''Genesis of the Daleks'', when the Daleks turn on Davros and his followers, Davros (in his one and only moment of compassion) begs the Daleks to have pity on the scientists who helped to create them - but they don't, because Davros did not include pity in their data banks. More or less the same exact thing happens ''every single time he appears''- he makes more Daleks to replace the batch the Doctor has killed, and they turn on and either kill or imprison him soon afterwards. You'd think he'd notice the pattern at some point, but no.
*** By the time Davros appears in "The Magician's Apprentice/The Witch's Familiar", he's actually become GenreSavvy enough to build a force field into his life-support wheelchair, preventing the Daleks from harming him should they turn on him. The Doctor, however, is GenreSavvy enough to know that Davros would do this, so he steals the wheelchair and goes off to confront the Daleks, safe in the knowledge they can't harm him. [[SubvertedTrope Colony Sarff, however, can]]. The trope is still played straight in the end: Davros' ultimate plan is to lure the Doctor into a trap and then harness his regeneration energy, revitalizing not only himself but also every Dalek on Skaro. [[GoneHorriblyRight Including the]] [[BodyHorror horribly decayed]], [[AndIMustScream but still living]] Daleks that make up the city's sewers. The Doctor, knowing this would happen, went along with Davros' plan, and then flees while the vengeful decayed Daleks tear the city apart from within and destroy their fully-functioning brethren.
** Similarly, in "The Age of Steel", John Lumic is defeated because all devices in the parallel universe are capable of interfacing with each other, allowing Mickey and the Doctor to get the code to deactivate the emotional inhibitors into the system.

* On ''Series/SiliconValley'' Hooli CEO Gavin hits this time ''Series/DoctorWho'':
** In the First Doctor story [[Recap/DoctorWhoS3E7TheCelestialToymaker "The Celestial Toymaker"]], the Doctor's companions, Steven
and again as Dodo, have to play a series of games against dolls which the titular Toymaker has brought to life. In the final episode, they must play a game similar to hopscotch against the Billy Bunter-esque Cyril. Determined to win at all costs, Cyril resorts to various underhanded tricks, including placing a slippery powder on one of the triangles, intending for either Dodo or Steven to fall onto the electrified floor. In the end, he is caught out by his every effort to make a name for himself blows up own trap when, in his face thanks eagerness to reach the finish line before his opponents, he forgets about the powder.
** The Second Doctor actually uses this phrase in [[Recap/DoctorWhoS6E7TheWarGames "The War Games"]], after subjecting the scientist
to his own work.

** He boasts of how Nucleus will offer Serially averted by the greatest live stream Master throughout Season Eight. He repeatedly tries to destroy life on Earth by unleashing an alien menace, only to end up helping the Doctor defeat it after realising in the nick of time that it's as much a UFC event ever seen. However, threat to him as anyone else.

Sadly, he's neglected turn on him. The Doctor, however, is GenreSavvy enough to remember know that non-compete clauses are illegal in California which means that ''every'' Hooli employee is freed of their contract Davros would do this, so he steals the wheelchair and goes off to confront the company owns ''nothing'' Daleks, safe in the knowledge they came up with. Needless to say, the board is not happy with this.
** He illegally alters Hooli software to automatically delete any news that speaks bad about them...only to have a reporter break the story first and has Gavin ripped on censorship.
** Gavin buys a company to get control of Pied Piper's work...which just means there's a concrete point of price on the work Pied Piper made.
** When it becomes clear Gavin has been covering up how Nucleus never worked amid all his other blunders, the board finally relieves him as CEO. They
can't fire him because of his contract so they just "transfer" him to another department...which ends up on the roof of the building with all the other guys Gavin has "transferred" over botched projects harm him.

* In
end: Davros' ultimate plan is to lure the Season 7 episode of ''Series/CurbYourEnthusiasm'' titled Doctor into a trap and then harness his regeneration energy, revitalizing not only himself but also every Dalek on Skaro. [[GoneHorriblyRight Including the]] [[BodyHorror horribly decayed]], [[AndIMustScream but still living]] Daleks that make up the city's sewers. The Doctor, knowing this would happen, went along with Davros' plan, and then flees while the vengeful decayed Daleks tear the city apart from within and destroy their fully-functioning brethren.

"The Black Swan," Larry tells Marty that introductions are a pointless and unnecessary social convention. Later, when Marty didn't introduce the Stonemason as Larry was calling him an asshole, Marty reminded him Robots of his own policy regarding introductions. Larry responds "So I'm hoisted on my petard."
** Larry David is late for a dinner because he's behind someone who takes a long time at a doctor's appointment, so he tells the doctor that patients should be admitted according to their appointment time. Later, he races to sign in at the doctor ahead of someone, but ends up going behind her because of the new policy, which goes with what David had ordered.

** In "The Snow Job," a family specialize in bilking people out of their homes. The team set up a con that gets them control of the company and the father arrested for fraud.

* In the ''Series/StargateAtlantis'' episode "The Tower", the villain dies due to a scratch from his own poisoned dagger. It is likely that this is a deliberate reference to the above-mentioned work of Creator/WilliamShakespeare, where Claudius and Laertes are both done in by the very poison they had conspired to kill Hamlet with. (Well, Claudius also gets ''stabbed'' a little bit. And, in one notable adaptation, [[FallingChandelierOfDoom hit by a chandelier]].)
* The Huntsman from ''Series/TheTenthKingdom.'' Earlier in the miniseries, we are told that his magic weapon is a crossbow that, when fired, shoots bolts that will not stop until they hit the heart of a living being. So quite naturally, during the climax when he and Wolf are struggling over the weapon and it is accidentally fired upwards through the skylight, the rule of KarmicDeath (as well as the law of gravity) dictates the arrow comes right back down and stabs the Huntsman in the heart from behind.
* In ''Series/{{Primeval}}'', Oliver Leek amasses a mind-controlled army of vicious predators from the future in a bid to obtain power. This royally screws up when the mind-control device breaks, and the predators kill him.

** In the earlier two-parter "Year of Hell", the BigBad uses a ship that has the power to RetGone anything. Janeway's HeroicSacrifice causes the ship to target ''itself'' and everything that happened in the episode is undone. Oddly enough, this actually gives the BigBad a ''happy'' ending -- he had unwittingly wiped out

He then attempts to beam off the station to let the crew mull his offer over, only to discover that one of his superior officers installed a similar program in case he ever tried to leave the station after triggering the self-destruct, an act that the superior officer considered to be Dukat abandoning his post. The program prevents Dukat from leaving the station and prevents him from using his access codes to stop the self destruct.
** In "The Die is Cast", the Obsidian Order and the Tal Shiar, the Cardassian and Romulan SecretPolice organizations respectively, launch a preemptive strike against the homeworld of the Founders, the Dominion's leaders. Except that they realize the planet was deserted, with a probe delivering false sensor readings, [[CurbStompBattle leading to a massive ambush by a Jem'Hadar fleet]]. Years earlier, in the ''Series/StarTrekTheNextGeneration'' episode "Chain of Command", the Cardassians also used this ploy to lure Captain Picard into a trap to be captured.
* The villain
wasn't killed in the ''Series/DoctorWho'' episode "Dalek", killed, but Henry van Staten surely paved the way for his eventual fate. His policy of using torture on his alien captive caused said alien to go on a murdering rampage when it finally got loose, and his fondness for wiping people's memories and dropping them off in a town starting with the same letter as their last name got turned around on him by his newly appointed [[TheStarscream second-in-command]].

** In ''Genesis of the Daleks'', when the Daleks turn on Davros and his followers, Davros (in his one and only moment of compassion) begs the Daleks to have pity on the scientists who helped to create them - but they don't, because Davros did not include pity in their data banks. More or less the same exact thing happens ''every single time he appears''- he makes more Daleks to replace the batch the Doctor has killed, and they turn on and either kill or imprison him soon afterwards. You'd think he'd notice the pattern at some point, but no.
*** By the time Davros appears in "The Magician's Apprentice/The Witch's Familiar", he's actually become GenreSavvy enough to build a force field into his life-support wheelchair, preventing the Daleks from harming him should they turn on him.

Cut to the end where sometimes they ''do'' get their sabotaged station back, and ultimately get eliminated for it.

Flagg made the mistake of recruiting Major Winchester into spying on Hawkeye; but he sorely misjudged Winchester's character. Winchester duped Flagg into thinking that a camp bridge game (which included the mayor of Uijongbu and his brother, the city's chief of police, as guest players), was a meeting of conspirators, which Flagg then attempted to raid. Even though they found out that Major Winchester set the whole thing up, the two angry South Korean officials vowed to use their US military contacts to ensure that Flagg would be punished; and since Flagg was never seen again in this series, they apparently succeeded.

* One episode of ''Series/{{CSI}}'' featured a woman and her father who co-owned a construction company and wanted to end the marriage to the woman's husband without getting a divorce, since Nevada divorce law would give the husband half of her shares in the company. They try to frame him for attempted murder, since Nevada law also requires that criminals not profit from their misdeeds, which would have meant the husband wouldn't get anything belonging to his wife. The scheme backfires horrifically when the [=CSIs=] uncover the woman and her father's plan and charge them with conspiracy, and it's implied that, under the very same law they tried to use to deprive the husband of any part of the construction company, he's going to end up owning the whole thing.

* Invoked in ''Series/RobinHood''...sort of. Guy of Gisborne gives his sister Isabella a vial of poison, intending for ''her'' to use it. She instead laces the blade of a dagger with it and stabs him in the back. On the other hand, Guy is also impaled on the sheriff's sword, an injury which kills him before the poison gets a chance.
** The Sheriff of Nottingham is blown up by explosives that he himself brought into the castle.
* On ''Series/{{Merlin}}'', Hengist, villain of ''Lancelot and Guinevere'', is killed and eaten by the pet monster he'd spent the whole episode feeding people too.

to:

** [=MacGyver=]'s nemesis, Murdoc, often exited the episode this way - -- the main difference being that since it only [[NoOneCouldSurviveThat appeared that he had died]], and they [[NeverFoundTheBody never found his body]], well, [[BackFromTheDead you know what that means]].
* In the Pie-lette of ''Series/PushingDaisies'' Chuck laments that she was hoisted by her own petard - her vacation was also smuggling monkey figurines, which got her killed. It prompts Ned's reply, "What's a petard?"
* Colonel Flagg fell victim to this in his final (and no-doubt most humiliating) scheme on ''Series/{{MASH}}'' When Hawkeye put the welfare of a communist soldier over another patient since the communist was in worse shape then the other patient, this naturally led to Flagg thinking Hawkeye was a Communist Sympathizer. Flagg made the mistake of recruiting Major Winchester into spying on Hawkeye; but he sorely misjudged Winchester's character. Winchester duped Flagg into thinking that a camp bridge game (which included the mayor of Uijongbu and his brother, the city's chief of police, as guest players), was a meeting of conspirators, which Flagg then attempted to raid. Even though they found out that Major Winchester set the whole thing up, the two angry South Korean officials vowed to use their US military contacts to ensure that Flagg would be punished; and since Flagg was never seen again in this series, they apparently succeeded.
succeeded.
* In ''Series/{{Heroes}}'', Mohinder talks about ''Series/{{Medium}}'' episode "You Give Me Fever", the upsides of Nathan Petrelli's plan guy responsible for [[FantasticRacism snatching and interning enhanced humans]], only causing another guy to get snatched kill himself shortly after by the stormtrooper squad.
* In ''Series/{{Life}}'' (season 1, "Powerless"), the main
infecting him with a deadly contagious disease. The villain becomes obsessed with Reese (they both go took a vaccine to protect himself. Allison confronted him but there was no proof other than her visions. The woman was upset until she had another dream. The villain was allergic to the same AA meetings, and he figures that she lied about her dark past), vaccine so he holds her hostage in her kitchen and forces her to drink a massive bottle of vodka, and finally she tells him about her past in a [[TheReasonYouSuckSpeech totally awesome speech]], and when he looks away for a second, she grabs the empty bottle of vodka and whacks him across the head with it, thus giving her partner and his backup time to break in and save her.
* In ''Series/TheCloser'' episode "Tijuana Brass", a corrupt Mexican cop looking for an accused murderer (who plans to testify against the drug cartel the cop works for) has the word spread among locked up convicts that whoever kills the guy he's looking for will get a big reward. After his corruption is ultimately revealed and the protagonists arrest him, his former coworkers book him under the name of the guy
he had put to take steroids to counter the hit on, which results in reaction but it made him being murdered in prison.
* Nonfatal example:
vulnerable to the [[ObstructiveBureaucrat humourless forum administrator]] flu. He was last seen in the children's television program ''Series/LiftOff'' was in hospital dying.
* ''Series/{{Merlin 1998}}'' has Mab. She created Merlin (half-human, half-fae) to preserve
the habit of digging up new things to ban, at one point producing a ban sign with a mirror on it. Then he was convinced to turn it around. Then pure force of LawfulNeutral kicks in.
* One episode of ''Series/{{CSI}}'' featured a woman
old ways. But, her cruel actions, such as killing his mother and her father who co-owned imprisoning a construction company and wanted lady he loved, made him instead want to end destroy the marriage to the woman's husband without getting a divorce, since Nevada divorce law would give the husband half of her shares in the company. They try to frame him for attempted murder, since Nevada law also requires that criminals not profit from their misdeeds, which would have meant the husband wouldn't get anything belonging to his wife. The scheme backfires horrifically when the [=CSIs=] uncover the woman and her father's plan and charge them with conspiracy, and it's implied that, under the very same law they tried to use to deprive the husband of any part of the construction company, he's going to end up owning the whole thing.
** Meanwhile, in [[Series/CSIMiami Miami]], a wife uses the fact that she's part of a set of triplets to set up what seems to be an airtight alibi for herself (and thus, all of them) for her husband's murder. Except it turns out that the husband has been using a body double
old ways. When he succeeds, Mab disappears because of his high profile job, and the body double was the one who died.
* In one episode of the new ''{{Series/Battlestar Galactica|2003}}'', in Season 2, a big Cylon Raider fleet fleet is disabled by a Cylon Logic Bomb, which they previously planted onto Galactica.
* The inventor of Hymie the KAOS robot on ''Series/GetSmart'' gets killed by his own invention. Something similar happens to many {{Big Bad}}s, including "Mr. Big" in the pilot.

** The Sheriff of Nottingham is blown up by explosives that he himself brought into the castle.
GodsNeedPrayerBadly.
* On ''Series/{{Merlin}}'', Hengist, villain of ''Lancelot "Lancelot and Guinevere'', Guinevere", is killed and eaten by the pet monster he'd spent the whole episode feeding people too.



** Morgana succeeds in her plan to make Guinevere look as [[MistakenForCheating though she was cheating on Arthur with Lancelot]] and have her banished from Camelot - unfortunately, these actions put Guinevere in a position where she is able to overhear Morgana's plans to invade Camelot, and race back to sound the alarm.
* On ''Series/{{Supernatural}}'', this happens all the time, normally to the humans who mess with the dark arts. They always get what's coming to them, and almost never from the main characters.
** Plus this is what the Trickster does to his victims. Ironically, it's also how he dies. He tries to trick Lucifer by creating a doppelganger of himself, but since Lucifer taught him how to do that in the first place, he easily sees through it and kills the real one.
** And in the Season 4 finale, Ruby reveals herself as TheMole and is killed by the Winchesters with the same demon-killing knife she's been carrying around for the last two seasons.

* On ''Series/{{Supernatural}}'', this happens all ''Series/ModelsInc.'' ended with Emma Samms' character getting shot by a hitman she'd hired to shoot her ex's new wife-to-be at the time, normally to wedding... but most viewers never saw this, as the humans who mess original broadcast of the episode ended on a CliffHanger at the fatal gunshot. Creator/AaronSpelling had the foresight to film an alternate ending in case of cancellation [[note]]but not enough foresight to also bring closure to Carrie Anne-Moss' storyline; if anything, Emma's death would have made things even worse for Carrie[[/note]].
* Season Ten of ''Series/MysteryScienceTheater3000'' has two examples of this:
** In the episode with ''Theatre/{{Hamlet}}'', Mike challenges Pearl to a Shell Game, winner gets to choose the movie. Mike wins and decides on ''Hamlet'' and mentions "any version". Boy, does Pearl ''give him Hamlet''!
** In the SeriesFinale featuring ''Film/DangerDiabolik'', Pearl goes on a madcap spree, pouring Mountain Dew on Brain Guy's brain, then futzing
with the dark arts. They always get what's Satellite of Love with a remote control. When the controller breaks and engages the reentry protocol, she can't fix it because Brain Guy's brain is still messed up!
** Season 9's episode featuring ''Film/{{Werewolf}}'' had Mike attempt an escape from the Satellite of Love. When Crow and Tom realize that he's not
coming to get them, and almost never from they move the main characters.
** Plus this is what
ladder over Castle Forrester.
* The ''Series/{{NCIS}}'' Season 11 episode "Bulletproof" centred around faulty body armor being sold to US military personnel -
the Trickster does manufacturer had passed the defective batch on to his victims. Ironically, it's also how he dies. He tries their recycling contractor to trick Lucifer by creating a doppelganger of himself, be disposed of, but since Lucifer taught him how to do that in the first place, he easily sees contractor instead sold them through it a middleman (who ended up as the BodyOfTheWeek). At the end of the episode, the team confront the recycling company's director, who hides inside a caravan and kills opens fire on the real one.
** And
agents. The agents return fire, and the director is killed - not by the bullets, but by her defective body armor shattering, causing fatal lacerations. For bonus irony points, Bishop was actually hit in the Season 4 finale, Ruby reveals herself as TheMole lower abdomen, but thanks to her own perfectly-functional body armor, she survived with only bruised ribs.
* A [[MonsterOfTheWeek club owner]] on ''Series/NCISLosAngeles'' hired the BodyOfTheWeek to build bombs to blow up a rival club. [[spoiler:He manages to get locked inside
and is killed by in the Winchesters with blast.]]
* ''Series/OnceUponATime'': Rumplestiltskin's plan to get to
the same demon-killing knife "real" world and find his son ends up backfiring on him when he [[spoiler: ends up trapped in Storybrooke just like everyone else, unable to leave lest he lose all of his Enchanted Forest memories- and therefore his memories of the very son he's there to find]].
** BiggerBad Cora has spent ''decades'' manipulating, abusing, and scheming to satisfy her unquenchable thirst for power and desire to hurt royalty out of revenge for their shoddy treatment of her, a lowborn miller's daughter. This includes using magic to kill Snow White's mother in a slow and painful fashion. Snow White tries to save her mother, and Cora tricks her into taking a black-magic enchanted candle that will save one life by killing someone else. Cora intended to corrupt Snow White in the process. As a child, Snow cannot bring herself to use it and loses her mother. But when Snow White is an adult, has been tormented by Regina (Cora's daughter, and the Wicked Stepmother) for well over 30 years, realizing Cora killed her mother, being ForcedToWatch as Cora and Regina murder her childhood nanny, and realizing Cora's got a scheme in the bag to achieve nearly godlike power by killing Rumplestitskin and gaining his power? Well, that candle ''does'' get used, Rumplestitskin is cured, and Cora's the one who dies by her own magic.
* ''Series/TheOuterLimits1963'' did this twice:
** The VillainProtagonist of "The Bellero Shield" is Judith Bellero, the scheming wife of an idealistic scientist, who learns the hard way that AmbitionIsEvil as
she's subjected to this trope ''twice''. When a gentle alien who protects himself with an impenetrable force field is accidentally drawn to her husband's lab, Judith kills him and passes off the force field as her husband's invention. Judith demonstrates the force field on herself--but realizes too late that only the alien can turn it off! Although the alien turns out to be NotQuiteDead and frees her before expiring, her guilt over the murder [[DrivenToMadness drives her insane]], a la Lady Theatre/{{Macbeth}}, and at the end she imagines herself still trapped behind the shield. "Nothing will ever remove it..."
** In "The Special One", alien invader Mr. Zeno poses as a human teacher to indoctrinate child prodigies. It turns out that the kid he's currently working with was playing FakeDefector all along, and uses one of Zeno's own weapons to force him to retreat to his home planet.
* ''Series/PersonOfInterest'' had Kara strapping a bomb vest on Agent Snow, using the threat of it detonating to make him work for her. Once she's through with him, she leaves the timer on the vest running and tells him that, if he runs fast enough, he might get it disarmed in time. Kara leaves the building after him, only to find him in the backseat of her car when the timer runs out.
* ''Franchise/PowerRangers'' villains tend to do this ''a lot''. Listed are the most notable and far-reaching examples:
** As far back as the pilot episode, the original team at first hardly believed Zordon's story and had little interest in fighting Rita. Then Rita decided to attack them first, and [[JumpedAtTheCall they changed their minds rather quickly.]] This rather bumbling and careless assault by Rita, in effect, created her worst enemies.
** And she wouldn't stop there. Rita was the one who made Tommy into the Green Ranger who would pretty much double the strength of the heroes after his HeelFaceTurn. He would be key to foiling many villainous threats for years to come, not just by Rita.
** Zedd's attempt to get rid of Tommy only hoisted him worse. By removing his Green Ranger powers, Tommy was able to become the more powerful White Ranger. In short, without either Rita or Lord Zedd, the Rangers would have
been carrying around unable to do anything against Master Vile's monsters which [[SortingAlgorithmOfEvil were considerably more powerful and dangerous]].
** In season two, Lord Zedd and Goldar's chased the Rangers to a far-off planet with the powerful DoomsdayDevice Serpentera. Impatient, Zedd decides to use Serpentera's main cannon to create an Earth-Shattering Kaboom despite Goldar's pleas. The Rangers escape with what they were looking for as the planet is destroyed and Zedd chases the Rangers back to Earth. When he tries this again, Serpentera's batteries run out of power, forcing him to retreat! From that point on, Serpentera, which was once a planet-destroying abomination, [[VillainDecay was a big pile of junk]] because the bad guys simply couldn't keep it fully-powered.
** Clearly having learned nothing from what happened with Tommy, Rita tried the same trick with Kat while working with Zedd as a team. It ended much the same way. (Kimberly even mentioned how Tommy joined the team later, and Kat would become the second Pink Ranger.)
** One of the biggest examples happens in ''Series/PowerRangersInSpace''. Dark Spector decided to brainwash away Astronema's HeelFaceTurn using implants. However, this [[GoneHorriblyRight works only too well]], making her a BastardUnderstudy. She used the Psycho Rangers to sap Dark Spector's power, weakening him so that she could [[TheStarscream kill him and take his place.]]
** Also happened later in ''Series/PowerRangersLightspeedRescue'', but this time it's the good guys on the receiving end. The Lightspeed Aquabase was built underwater in order to ensure that the demons would be unable to reach it. However, when the Season Finale arrives, one of the {{Elite Mook}}s uses a magic card that he stuck on the leg of their strongest Megazord to allow their Mooks to swarm the base and destroy it. And their main weapons were the rangers' own zords, which they hi-jacked.
* In ''Series/{{Primeval}}'', Oliver Leek amasses a mind-controlled army of vicious predators from the future in a bid to obtain power. This royally screws up when the mind-control device breaks, and the predators kill him.
** Similarly, the woman who had raised a saber-toothed tiger from a cub that she found is killed by it at the end.
* Happens three times on ''Series/ThePrisoner'':
** In "Checkmate", Number Six determines which of his fellow villagers are prisoners and which are guards by observing their mannerisms (prisoners are meek and submissive, while guards are defiant and confident). Using this knowledge, he recruits a team of prisoners to make an escape... and is foiled when they notice how confident and defiant ''he'' is, become convinced that he is a guard testing their loyalty, and turn him in to Number Two.
** In "A Change of Mind", the new Number Two uses psychological tactics cribbed from the RedScare and the UsefulNotes/CulturalRevolution to turn the whole Village against Number Six, declaring him an "[[IndividualityIsIllegal unmutual]]" and ostracizing him. At the end of the episode, Number Six, pretending to have been converted by the experience, persuades Number Two to call the whole Village together for his public confession and repudiation of his sins. Instead, he uses the opportunity to have someone declare that ''Number Two'' is "unmutual." The villagers, conditioned by Number Two to automatically believe such accusations, form an angry mob and run him out of town.
** In "Hammer Into Anvil", Number 6 uses Mind Games (and the inherent paranoia of the Village) to drive the current Number 2 into reporting ''himself'' to the authorities for incompetence.
* In ''Series/{{Psych}}'''s first season, episode twelve ("Cloudy With A Chance of Murder") features Shawn and Gus as legal consultants to the defense of what seems to be a hopeless case. There's a mountain of evidence against them, and just when they're starting to get an advantage, the prosecution produces a video that provides proof of the defendant's guilt. With Shawn's hyper-observative skills, he uses it to instead prove her innocence and force the real perpetrator to confess.
* In the Pie-lette of ''Series/PushingDaisies'' Chuck laments that she was hoisted by her own petard -- her vacation was also smuggling monkey figurines, which got her killed. It prompts Ned's reply, "What's a petard?"
* Invoked in ''Series/RobinHood''... sort of. Guy of Gisborne gives his sister Isabella a vial of poison, intending for ''her'' to use it. She instead laces the blade of a dagger with it and stabs him in the back. On the other hand, Guy is also impaled on the sheriff's sword, an injury which kills him before the poison gets a chance.
** The Sheriff of Nottingham is blown up by explosives that he himself brought into the castle.
* ''Series/RobotWars'':
** The most common source of this trope was for one robot to try and push another into an arena hazard such as the Pit of Oblivion, only to get caught itself. Cassius 2's loss to Pussycat in Series 3, one of the most {{Shocking Elimination}}s in the show's history, was the result of Pussycat moving out of the way at ''just'' the right moment so that Cassius went charging straight into the open pit.
*** From Extreme 1/Series 5 onwards, the pit was opened by a button on the arena wall, meaning a robot could potentially fall into a pit that it had opened itself. Both The Executioner and Major Tom managed to fall into the pit ''[[EpicFail immediately after opening it]]'', with the latter incident being voted [[Funny/RobotWars the funniest moment of the Fifth Wars]] just
for the sheer comedic stupidity.
** The trope name was said in full on at least one occasion: in Series 2, during Caliban's Gauntlet run, Sir Killalot proceeded to pick it up by its own flail weapon, prompting Jonathan Pearce to say the phrase. Caliban came
last two seasons.with a score of just 0.2m, the worst in the show's history, and was eliminated. A very literal version of the trope.
** Another literal example came in Series 3 when the highly-fancied Razer suffered a mechanical malfunction that left it stuck in its VictoryPose, in which it raises its crushing claw to its highest extent, its self-righting wings extending outwards and its "tail" lifting its wheels off the ground. Unable to move, it was counted out and eliminated.
** Chaos 2's SignatureMove during its title-winning runs in Series 3 and 4 was to [[RingOut flip opponents clean out of the arena]]. Its last-ever battle in the main series was the Series 6 heat final against Dantomkia, and after Chaos 2's flipper failed, Dantomkia threw it out of the arena, subjecting it to the very same fate it had inflicted on so many robots over the years.



* On Creator/SpikeTV's ''Series/OneThousandWaysToDie'', a pair of dimwitted terrorists were blown up by their own bomb when they forgot about daylight savings time while setting the device's GPS-based timer.
* The BigBad of ''{{Series/Dollhouse}}'', [[spoiler:Boyd Langton]], spent a good portion of S2 manipulating the main cast into creating and handing over a device capable of wiping and imprinting ''anyone'', not just Actives. Topher uses it to wipe [[spoiler:Boyd]], reducing him to a Doll-state, and he blindly--''happily!''--follows Echo's instructions to strap a bomb to his body and blow up the Rossum headquarters.
* In an episode of ''Series/TheAdventuresOfSuperboy'', a demon turns Loretta York into Yellow Peri, a powerful witch who wreaks havoc. When Superboy confronts them, Yellow Peri sets a photo of him on fire. Like a voodoo doll, this causes him to burst into flames, falling to the floor and screaming in agony. The demon laughs and mocks him. Angrily, Superboy blasts him with heat vision, but it has no effect. The demon [[VillainBall smugly boasts that only magic can hurt him]], and Superboy immediately grabs him, causing the fire to spread to him and reduce him to ashes. Fortunately, [[NoOntologicalInertia with him gone, his curses wear off]], Superboy is healed, and Yellow Peri reverts to Lorretta York.
* Obligatory examples from ''Series/BuffyTheVampireSlayer'' and ''Series/{{Angel}}'':
** Non-death example: In the sixth-season episode "Older and Far Away," Dawn makes a wish to the vengeance demon Halfrek that everybody would spend more time with her. Halfrek makes the dream come true by magically making it impossible for any of the guests at Buffy's birthday party to leave the house. She then comes and taunts them... until she realizes that ''she'' can't escape the house, either, and reluctantly reverses the spell.
** Another non-death example: [[BigBad The First Evil]] attempts to drive Angel to kill Buffy using the same {{mind rap|e}}ing tactics he himself used to great effect. It's happy with him being DrivenToSuicide however.
** Death example: Maggie Walsh is killed by her own creation that she was planning to sic on the heroes.
** Happens to Angel, in every sense of the word. Buffy runs him through with a replica of his own blessed sword, which in turns sucks him through his own hell portal. Putting a damper on this irony is the knowledge that Angel suffers the fate reserved for Angelus, because he regained his soul moments beforehand and that brief vulnerability may well have been what allowed Buffy's victory.
** When Dark Willow catches up to Warren, she begins by torturing him with the very bullet he used to shoot Buffy.
** Giles uses a spell from Roden's spellbook to kill him.
** Buffy puts Faith in a coma by stabbing her in the gut with her own knife.
** Non-death example: After successfully {{blackmail}}ing Angel into springing AxCrazy HeManWomanHater Billy Blim from a PrisonDimension, Lilah's manipulations come back and bite her in the ass when Billy "[[UngratefulBastard thanks]]" her by first giving the credit to her [[TheRival rival]] Gavin and then [[HatePlague inducing]] him to beat the ever-loving shit out of her while he walks away with a PsychoticSmirk on his face, leading to Lilah [[EnemyMine helping]] Angel Investigations take him out.
* In ''[[YesMinister Yes, Prime Minister]]'', Sir Humphrey enacts a masterful gambit to ensure that the Employment Secretary is removed from his post after suggesting a brilliant idea to move large sections of the armed forces OopNorth, which has received much hostility from senior civil servants and military officials because they'll, well, be OopNorth and far away from Harrods and Wimbledon and all the nice cushy things down south which they like. He expertly plays on Hacker's paranoia to make Hacker think that the Employment Secretary is using this plan as part of a coup to secure Hacker's job. It works, the plan is scuttled, the Employment Secretary gone, and Humphrey is left to leave in smug satisfaction of another job well done... until in the last minute of the episode, Hacker realizes that now the Employment Secretary is gone, there's nothing to stop him safely implementing the plan...
* ''ModelsInc.'' ended with Emma Samms' character getting shot by a hitman she'd hired to shoot her ex's new wife-to-be at the wedding... but most viewers never saw this, as the original broadcast of the episode ended on a CliffHanger at the fatal gunshot. Creator/AaronSpelling had the foresight to film an alternate ending in case of cancellation [[note]]but not enough foresight to also bring closure to Carrie Anne-Moss' storyline; if anything, Emma's death would have made things even worse for Carrie[[/note]].
* In ''Series/{{Medium}}'' episode "You Give Me Fever", the guy responsible for causing another guy to kill himself after infecting him with a deadly contagious disease. The villain took a vaccine to protect himself. Allison confronted him but there was no proof other than her visions. The woman was upset until she had another dream. The villain was allergic to the vaccine so he had to take steroids to counter the reaction but it made him vulnerable to the flu. He was last seen in the hospital dying.
* In the final episode of ''Series/{{Blackadder}} II'', Ludwig the Indestructible prides himself on being a MasterOfDisguise, and plans to use this, and the knowledge that Nursie always goes to fancy dress parties as a cow, to infiltrate Queen Elizabeth's court. Unfortunately, his pride in his disguises means he makes the mistake of disguising himself as a cow, rather than as a mad old woman with an udder fixation.
* In ''Series/{{Psych}}'''s first season, episode twelve ("Cloudy With A Chance of Murder") features Shawn and Gus as legal consultants to the defense of what seems to be a hopeless case. There's a mountain of evidence against them, and just when they're starting to get an advantage, the prosecution produces a video that provides proof of the defendant's guilt. With Shawn's hyper-observative skills, he uses it to instead prove her innocence and force the real perpetrator to confess.
* ''Series/{{Merlin 1998}}'' has Mab. She created Merlin (half-human, half-fae) to preserve the old ways. But, her cruel actions, such as killing his mother and imprisoning a lady he loved, made him instead want to destroy the old ways. When he succeeds, Mab disappears because GodsNeedPrayerBadly.
* An episode of ''Series/ColdCase'' featured a villain who would abduct women and imprison them in a windowless cell for months in order to break their spirit. Once this was achieved, he would [[LockedUpAndLeftBehind leave them there to starve to death]]. However, he stashes his latest victim within hearing distance of a church that rings its bells every Sunday. With this, the woman is able to keep track of the days and retain her sanity. Her refusal to snap rattles him so much that he finally makes a mistake that gets him arrested. To top it off, at the episode's end, we see him being tossed into a cell very much like the one he'd barricaded his victims in -- and he's claustrophobic.
** In another episode, the villain, who had been correctly identified as the prime suspect when the case was still hot, framed someone else for the murder and went to the police himself to get the case reopened, in the hopes of getting the other guy arrested and himself cleared. Needless to say, his doing this backfired.
** Still another had a particularly loathsome killer [[ForcedToWatch forcing his little niece]] to watch the murder to "teach her a lesson." Guess whose testimony turns out to be just the evidence the cops need to put him away?

** Realizing he needs a scapegoat, Gavin talks that division head into coming back, promising to give
him safely implementing full control over the plan...
* ''ModelsInc.'' ended with Emma Samms' character getting shot by a hitman she'd hired to shoot her ex's new wife-to-be
project. The man takes one look at the wedding... but most viewers never saw Nucleus code, realizes how unsalvagable it is and literally races away from the company. Reporting this, as the original broadcast Gavin's lawyers (unaware of the episode ended on truth) think this is a CliffHanger at the fatal gunshot. Creator/AaronSpelling had the foresight to film an alternate ending in case of cancellation [[note]]but not enough foresight to also bring closure to Carrie Anne-Moss' storyline; if anything, Emma's death would have made things even worse for Carrie[[/note]].
* In ''Series/{{Medium}}'' episode "You Give Me Fever", the guy
good thing as now "the whole world will know you and you alone are responsible for causing another guy to kill himself after infecting him with a deadly contagious disease. The villain took a vaccine to protect himself. Allison confronted him but there was no proof other than her visions. The woman was upset until she had another dream. The villain was allergic to the vaccine so he had to take steroids to counter the reaction but it made him vulnerable to the flu. He was last seen in the hospital dying.
* In the final episode of ''Series/{{Blackadder}} II'', Ludwig the Indestructible prides himself on being a MasterOfDisguise, and plans to use this, and the knowledge that Nursie always goes to fancy dress parties as a cow, to infiltrate Queen Elizabeth's court. Unfortunately, his pride in his disguises means he makes the mistake of disguising himself as a cow, rather than as a mad old woman with an udder fixation.
* In ''Series/{{Psych}}'''s first season, episode twelve ("Cloudy With A Chance of Murder") features Shawn and Gus as legal consultants to the defense of what seems to be a hopeless case. There's a mountain of evidence against them, and just when they're starting to get an advantage, the prosecution produces a video that provides proof of the defendant's guilt. With Shawn's hyper-observative skills, he uses it to instead prove her innocence and force the real perpetrator to confess.
* ''Series/{{Merlin 1998}}'' has Mab. She created Merlin (half-human, half-fae) to preserve the old ways. But, her cruel actions, such as killing his mother and imprisoning a lady he loved, made him instead want to destroy the old ways. When he succeeds, Mab disappears because GodsNeedPrayerBadly.
* An episode of ''Series/ColdCase'' featured a villain who would abduct women and imprison them in a windowless cell for months in order to break their spirit. Once this was achieved, he would [[LockedUpAndLeftBehind leave them there to starve to death]]. However, he stashes his latest victim within hearing distance of a church that rings its bells every Sunday. With this, the woman is able to keep track of the days and retain her sanity. Her refusal to snap rattles him so much that he finally makes a mistake that gets him arrested. To top it off, at the episode's end, we see him being tossed into a cell very much like the one he'd barricaded his victims in -- and
Nucleus."
** Gavin thinks
he's claustrophobic.
** In another episode,
got the villain, who had been correctly identified as perfect ammo against Pied Piper by revealing Hooli has a non-compete clause in employee contracts which means he owns what they came up with while working for Hooli. Sadly, he's neglected to remember that non-compete clauses are illegal in California which means that ''every'' Hooli employee is freed of their contract and the prime suspect when the case was still hot, framed someone else for the murder and went to the police himself to get the case reopened, in the hopes of getting the other guy arrested and himself cleared. company owns ''nothing'' they came up with. Needless to say, the board is not happy with this.
** He illegally alters Hooli software to automatically delete any news that speaks bad about them... only to have a reporter break the story first and has Gavin ripped on censorship.
** Gavin buys a company to get control of Pied Piper's work... which just means there's a concrete point of price on the work Pied Piper made.
** When it becomes clear Gavin has been covering up how Nucleus never worked amid all
his doing this backfired.
** Still
other blunders, the board finally relieves him as CEO. They can't fire him because of his contract so they just "transfer" him to another department... which ends up on the roof of the building with all the other guys Gavin has "transferred" over botched projects in the past.
* When a crowd of zombie slaves regains their sanity in ''Series/SirArthurConanDoylesTheLostWorld'', they turn on their voodoo master, with vicious results.
* In ''Series/{{Spaced}}'', Bilbo mentions a friend of his who trained a dog to attack rich people, only to get mauled by it after winning some money on a scratchcard.
* In the ''Series/StargateAtlantis'' episode "The Tower", the villain dies due to a scratch from his own poisoned dagger. It is likely that this is a deliberate reference to the above-mentioned work of Creator/WilliamShakespeare, where Claudius and Laertes are both done in by the very poison they
had conspired to kill Hamlet with. (Well, Claudius also gets ''stabbed'' a particularly loathsome killer [[ForcedToWatch forcing his little niece]] to watch bit. And, in one notable adaptation, [[FallingChandelierOfDoom hit by a chandelier]].)
* In
the murder to "teach GrandFinale of ''Series/StarTrekVoyager'', the Borg Queen is tricked into assimilating Future-Janeway, causing her to contract a lesson." Guess whose testimony nanovirus (ten years in the making and about seventeen ahead of its time), killing her... [[DeathIsCheap again]].
** In the earlier two-parter "Year of Hell", the BigBad uses a ship that has the power to RetGone anything. Janeway's HeroicSacrifice causes the ship to target ''itself'' and everything that happened in the episode is undone. Oddly enough, this actually gives the BigBad a ''happy'' ending -- he had unwittingly wiped out his own homeworld and family when he used the ship during a war. With the ship gone from the timeline, the life he lost had been restored. [[spoiler: [[StableTimeLoop Though he is once again working on temporal calculations]]]].
* In the ''Series/StarTrekDeepSpaceNine'' episode "Civil Defence", the crew accidentally triggers an automated defense program left behind by the station's previous commander, Gul Dukat. After the crew's failure to circumvent the program triggers the station's self destruct, Dukat himself shows up and offers to save them if they give his people massive diplomatic concessions. He then attempts to beam off the station to let the crew mull his offer over, only to discover that one of his superior officers installed a similar program in case he ever tried to leave the station after triggering the self-destruct, an act that the superior officer considered to be Dukat abandoning his post. The program prevents Dukat from leaving the station and prevents him from using his access codes to stop the self destruct.
** In "The Die is Cast", the Obsidian Order and the Tal Shiar, the Cardassian and Romulan SecretPolice organizations respectively, launch a preemptive strike against the homeworld of the Founders, the Dominion's leaders. Except that they realize the planet was deserted, with a probe delivering false sensor readings, [[CurbStompBattle leading to a massive ambush by a Jem'Hadar fleet]]. Years earlier, in the ''Series/StarTrekTheNextGeneration'' episode "Chain of Command", the Cardassians also used this ploy to lure Captain Picard into a trap to be captured.
* The first season finale of ''Series/StrikeBack'' features the BigBad, Latif, attempting to use VX gas on the leaders of several European countries and the United States by implanting explosive canisters filled with the nerve agent inside a pair of suicide bombers, while simultaneously kidnapping Grant and a Pakistani presidential candidate, all to expose the truth about Pakistan's involvement in a plot to plant [=WMDs=] in Iraq to justify the war. Little does he know that Grant had grabbed an empty container (the explosive core of which is volatile enough to be set off by a direct hit from a bullet) recovered from his Chechen base in the previous episode. So when he tries to force Grant into a car at gunpoint, she points the gun at the canister (still on her, [[IdiotBall somehow]]) and pulls the trigger for him.
* Daniel Hardman of ''Series/{{Suits}}'' deliberately [[spoiler:planted fradulent evidence to implicate his own firm in a cover-up]]. Events were such that blame fell on Jessice Pearce's shoulders, giving Hardman just enough votes to replace her as managing partner. Unfortunately for him, [[spoiler:doing so cost each voting member $100,000 and when it was revealed he was the reason for that loss, the member unanimously fired him]].
** Mike Ross of the same series isn't a villain, he got into the law business to help people. But he IS a fraud, since he got his job by lying about graduating from Harvard, and arranged for Harvard and the state bar to be hacked to forge credentials for him (which show him graduating ''Summa Cum Laude''). Mike's eidetic memory is one of his greatest strengths. He's also a generally nice guy and tries to get along with others, even the firm's ButtMonkey Louis Litt. Litt '''actually''' graduated from Harvard, like everyone else at the firm, with real honors as high as Mike's fake ones, not as flashy or imposing as Harvey but with his own skills at AwesomenessByAnalysis. When helping Louis move, Mike repeatedly asks him about a key, [[spoiler: which
turns out to be a symbol of a Harvard honor society that Mike's forged records show he should be a member of.]] But Mike didn't recognize it. And he can't have just forgotten it, because Mike Ross doesn't forget '''anything'''. So Louis now knows that Mike is a fraud, and Harvey and Jessica have been aiding in that fraud, which he uses to blackmail his way into becoming Named Partner. But in doing so, Louis himself becomes a party to the evidence fraud, and has to help cover it up for his own safety, so the cops need weapon he used against Harvey and Jessica is now a danger to put him.
** A client being used as a scapegoat in a securities fraud case thought he was safe because not only did he not actually commit the crime he was accused of, the only person he ever told about how guilty he felt for participating in his firm's shady dealings was his therapist, and his conversations with her should be privileged and inadmissible. But he forgot that she was paid by his firm, so privilege was waived, and she was forced to testify to what he said in therapy, which his employers spun to use against him. But Harvey (another of her patients), not only cast doubt on her testimony by himself revealing embarrassing information she told
him away?in confidence, but convinced her to help him get the company to back off by threatening to reveal incriminating statements (which may or may not actually exist) from other patients working for the same company, ''which wouldn't be admissible if not for the fact that the company had opened the door by forcing the therapist to testify in the first place''.
* On ''Series/{{Supernatural}}'', this happens all the time, normally to the humans who mess with the dark arts. They always get what's coming to them, and almost never from the main characters.
** Plus this is what the Trickster does to his victims. Ironically, it's also how he dies. He tries to trick Lucifer by creating a doppelganger of himself, but since Lucifer taught him how to do that in the first place, he easily sees through it and kills the real one.
** And in the Season 4 finale, Ruby reveals herself as TheMole and is killed by the Winchesters with the same demon-killing knife she's been carrying around for the last two seasons.
* ''Series/{{Survivor}}'' has plenty of examples:
** The coconut challenge had the Rotu 4 from the fourth season of Survivor lay out the boot order leading the non-members of the tribe to form a counteralliance voting the Rotu 4 out of the game.
** Laura M. try to keep Tina Wesson around during her second stay at Redemption Island during Blood vs. Water only for Tina to beat her in the final challenge.
** Stephen's downfall in his second season has to be be this. First of all, his advantage lead him to become even more of a threat than he did and taking Tasha and Jeremy to the reward challenge lead Spencer feel like he is on the bottom of his alliance and made a move to get rid of Stephen
** From Kaoh Rong, Aubry's aggressive gameplay mixed with her indecisiveness in the beginning of the game as well as doing too good of a job at keeping her scheming secret to the point nobody knew what she did until after the season lead her to lose the game.
** Val from San Juan Del Sur went on to state that she ended up two idols in the game as a way to save herself. Too bad her other tribemates bought that lie leading to her being eliminated from the game.
** From Cagayan, Garrett went on to have a tribe forum to make sure no one freaked out or didn't vote for J'Tia only for Kass and Tasha to blindslide from the game after being brought attention to himself. He also assumed [[EpicFail he was safe and let his idol back at the camp]].



* ''Series/RobotWars'':
** The most common source of this trope was for one robot to try and push another into an arena hazard such as the Pit of Oblivion, only to get caught itself. Cassius 2's loss to Pussycat in Series 3, one of the most {{Shocking Elimination}}s in the show's history, was the result of Pussycat moving out of the way at ''just'' the right moment so that Cassius went charging straight into the open pit.
*** From Extreme 1/Series 5 onwards, the pit was opened by a button on the arena wall, meaning a robot could potentially fall into a pit that it had opened itself. Both The Executioner and Major Tom managed to fall into the pit ''[[EpicFail immediately after opening it]]'', with the latter incident being voted [[Funny/RobotWars the funniest moment of the Fifth Wars]] just for the sheer comedic stupidity.
** The trope name was said in full on at least one occasion: in Series 2, during Caliban's Gauntlet run, Sir Killalot proceeded to pick it up by its own flail weapon, prompting Jonathan Pearce to say the phrase. Caliban came last with a score of just 0.2m, the worst in the show's history, and was eliminated. A very literal version of the trope.
** Another literal example came in Series 3 when the highly-fancied Razer suffered a mechanical malfunction that left it stuck in its VictoryPose, in which it raises its crushing claw to its highest extent, its self-righting wings extending outwards and its "tail" lifting its wheels off the ground. Unable to move, it was counted out and eliminated.
** Chaos 2's SignatureMove during its title-winning runs in Series 3 and 4 was to [[RingOut flip opponents clean out of the arena]]. Its last-ever battle in the main series was the Series 6 heat final against Dantomkia, and after Chaos 2's flipper failed, Dantomkia threw it out of the arena, subjecting it to the very same fate it had inflicted on so many robots over the years.
* In the ''Series/{{Bones}}'' episode "The Bullet in the Braincase", a sniper who has been using the names of other snipers in order to purchase supplies (and sticking them with the bills) is located when Booth discovers a piece of land bought using his name. When Booth confronts him, the sniper taunts him to jump the fence and enter the property without a warrant. Booth jumps the fence and points out he doesn't need a warrant; after all, the property belongs to ''Seeley Booth''. Cue the OhCrap look and the suspect running away.
* One episode of ''Series/HogansHeroes'' had Hogan explicitly invoke this trope to describe how a plan had gone wrong/would go wrong.
* ''Series/{{Community}}'':
** In the episode "[[Recap/CommunityS1E08HomeEconomics Home Economics]]" this ends up happening to Vaughn. His usual method of revenge for people who piss him off is to write songs with [[CreatorBreakdown rather passive-aggressively spiteful lyrics]] in which he denounces them as a 'B'. Unfortunately for him, he gets a response song written about him in TheTag, which he apparently did not anticipate.
** In a Season 6 episode, Britta gives her convoluted explanation about how she ''thinks'' the phrase "hoisted by your own petard" originated.
-->'''Britta''': [[IThoughtItMeant I guess I just assumed]] that in the old days a petard was a special outfit like a leotard, with a lot of fancy buckles and loops on it, and that rich people would wear them when they were feeling especially smug, but then poor people would tie a rope through one of the loops, and hoist them up a pole and then let them dangle there as punishment for being cocky.\\
'''Jeff''': Never look it up. Your explanation is way better.
** In [[Recap/CommunityS6E11ModernEspionage Modern Espionage]] the enemy paintballer sets up a bunch of mannequins as decoys, only to get so involved in his NotSoDifferent speech that he mistakes his opponents for them and walks out into the open.
* ''Series/TheOuterLimits1963'' did this twice:
** The VillainProtagonist of "The Bellero Shield" is Judith Bellero, the scheming wife of an idealistic scientist, who learns the hard way that AmbitionIsEvil as she's subjected to this trope ''twice''. When a gentle alien who protects himself with an impenetrable force field is accidentally drawn to her husband's lab, Judith kills him and passes off the force field as her husband's invention. Judith demonstrates the force field on herself--but realizes too late that only the alien can turn it off! Although the alien turns out to be NotQuiteDead and frees her before expiring, her guilt over the murder [[DrivenToMadness drives her insane]], a la Lady Theatre/{{Macbeth}}, and at the end she imagines herself still trapped behind the shield. "Nothing will ever remove it..."
** In "The Special One", alien invader Mr. Zeno poses as a human teacher to indoctrinate child prodigies. It turns out that the kid he's currently working with was playing FakeDefector all along, and uses one of Zeno's own weapons to force him to retreat to his home planet.
* Happens three times on ''Series/ThePrisoner'':
** In "Checkmate," Number Six determines which of his fellow villagers are prisoners and which are guards by observing their mannerisms (prisoners are meek and submissive, while guards are defiant and confident). Using this knowledge, he recruits a team of prisoners to make an escape...and is foiled when they notice how confident and defiant ''he'' is, become convinced that he is a guard testing their loyalty, and turn him in to Number Two.
** In "A Change of Mind," the new Number Two uses psychological tactics cribbed from the RedScare and the UsefulNotes/CulturalRevolution to turn the whole Village against Number Six, declaring him an "[[IndividualityIsIllegal unmutual]]" and ostracizing him. At the end of the episode, Number Six, pretending to have been converted by the experience, persuades Number Two to call the whole Village together for his public confession and repudiation of his sins. Instead, he uses the opportunity to have someone declare that ''Number Two'' is "unmutual." The villagers, conditioned by Number Two to automatically believe such accusations, form an angry mob and run him out of town.
** In "Hammer Into Anvil", Number 6 uses Mind Games (and the inherent paranoia of the Village) to drive the current Number 2 into reporting ''himself'' to the authorities for incompetence.
* Season Ten of ''Series/MysteryScienceTheater3000'' has two examples of this:
** In the episode with ''Theatre/{{Hamlet}}'', Mike challenges Pearl to a Shell Game, winner gets to choose the movie. Mike wins and decides on ''Hamlet'' and mentions "any version". Boy, does Pearl ''give him Hamlet''!
** In the SeriesFinale featuring ''Film/DangerDiabolik'', Pearl goes on a madcap spree, pouring Mountain Dew on Brain Guy's brain, then futzing with the Satellite of Love with a remote control. When the controller breaks and engages the reentry protocol, she can't fix it because Brain Guy's brain is still messed up!
** Season 9's episode featuring ''Film/{{Werewolf}}'' had Mike attempt an escape from the Satellite of Love. When Crow and Tom realize that he's not coming to get them, they move the ladder over Castle Forrester.
* ''Franchise/PowerRangers'' villains tend to do this ''a lot''. Listed are the most notable and far-reaching examples:
** As far back as the pilot episode, the original team at first hardly believed Zordon's story and had little interest in fighting Rita. Then Rita decided to attack them first, and [[JumpedAtTheCall they changed their minds rather quickly.]] This rather bumbling and careless assault by Rita, in effect, created her worst enemies.
** And she wouldn't stop there. Rita was the one who made Tommy into the Green Ranger who would pretty much double the strength of the heroes after his HeelFaceTurn. He would be key to foiling many villainous threats for years to come, not just by Rita.
** Zedd's attempt to get rid of Tommy only hoisted him worse. By removing his Green Ranger powers, Tommy was able to become the more powerful White Ranger. In short, without either Rita or Lord Zedd, the Rangers would have been unable to do anything against Master Vile's monsters which [[SortingAlgorithmOfEvil were considerably more powerful and dangerous]].
** In season two, Lord Zedd and Goldar's chased the Rangers to a far-off planet with the powerful DoomsdayDevice Serpentera. Impatient, Zedd decides to use Serpentera's main cannon to create an Earth-Shattering Kaboom despite Goldar's pleas. The Rangers escape with what they were looking for as the planet is destroyed and Zedd chases the Rangers back to Earth. When he tries this again, Serpentera's batteries run out of power, forcing him to retreat! From that point on, Serpentera, which was once a planet-destroying abomination, [[VillainDecay was a big pile of junk]] because the bad guys simply couldn't keep it fully-powered.
** Clearly having learned nothing from what happened with Tommy, Rita tried the same trick with Kat while working with Zedd as a team. It ended much the same way. (Kimberly even mentioned how Tommy joined the team later, and Kat would become the second Pink Ranger.)
** One of the biggest examples happens in ''Series/PowerRangersInSpace''. Dark Spector decided to brainwash away Astronema's HeelFaceTurn using implants. However, this [[GoneHorriblyRight works only too well]], making her a BastardUnderstudy. She used the Psycho Rangers to sap Dark Spector's power, weakening him so that she could [[TheStarscream kill him and take his place.]]
** Also happened later in ''Series/PowerRangersLightspeedRescue'', but this time it's the good guys on the receiving end. The Lightspeed Aquabase was built underwater in order to ensure that the demons would be unable to reach it. However, when the Season Finale arrives, one of the {{Elite Mook}}s uses a magic card that he stuck on the leg of their strongest Megazord to allow their Mooks to swarm the base and destroy it. And their main weapons were the rangers' own zords, which they hi-jacked.
* The ''Series/{{NCIS}}'' Season 11 episode "Bulletproof" centred around faulty body armor being sold to US military personnel - the manufacturer had passed the defective batch on to their recycling contractor to be disposed of, but the contractor instead sold them through a middleman (who ended up as the BodyOfTheWeek). At the end of the episode, the team confront the recycling company's director, who hides inside a caravan and opens fire on the agents. The agents return fire, and the director is killed - not by the bullets, but by her defective body armor shattering, causing fatal lacerations. For bonus irony points, Bishop was actually hit in the lower abdomen, but thanks to her own perfectly-functional body armor, she survived with only bruised ribs.
* A [[MonsterOfTheWeek club owner]] on ''Series/NCISLosAngeles'' hired the BodyOfTheWeek to build bombs to blow up a rival club. [[spoiler:He manages to get locked inside and is killed in the blast.]]



* The first season finale of ''Series/StrikeBack'' features the BigBad, Latif, attempting to use VX gas on the leaders of several European countries and the United States by implanting explosive canisters filled with the nerve agent inside a pair of suicide bombers, while simultaneously kidnapping Grant and a Pakistani presidential candidate, all to expose the truth about Pakistan's involvement in a plot to plant [=WMDs=] in Iraq to justify the war. Little does he know that Grant had grabbed an empty container (the explosive core of which is volatile enough to be set off by a direct hit from a bullet) recovered from his Chechen base in the previous episode. So when he tries to force Grant into a car at gunpoint, she points the gun at the canister (still on her, [[IdiotBall somehow]]) and pulls the trigger for him.
* Daniel Hardman of ''Series/{{Suits}}'' deliberately [[spoiler:planted fradulent evidence to implicate his own firm in a cover-up]]. Events were such that blame fell on Jessice Pearce's shoulders, giving Hardman just enough votes to replace her as managing partner. Unfortunately for him, [[spoiler:doing so cost each voting member $100,000 and when it was revealed he was the reason for that loss, the member unanimously fired him]].
** Mike Ross of the same series isn't a villain, he got into the law business to help people. But he IS a fraud, since he got his job by lying about graduating from Harvard, and arranged for Harvard and the state bar to be hacked to forge credentials for him (which show him graduating ''Summa Cum Laude'').

And he can't have just forgotten it, because Mike Ross doesn't forget '''anything'''. So Louis now knows that Mike is a fraud, and Harvey and Jessica have been aiding in that fraud, which he uses to blackmail his way into becoming Named Partner. But in doing so, Louis himself becomes a party to the fraud, and has to help cover it up for his own safety, so the weapon he used against Harvey and Jessica is now a danger to him.

* On ''Series/EliStone'', Jordan is nearly killed in an earthquake and the experience changes his view on the world. Jordan decides to change the firm to help those who can't afford fancy lawyers rather than their high-priced (and often corrupt) clients. Rather than join him, his two partners force Jordan out of the firm. They come by as Jordan is packing up his office to give a "no hard feelings" talk only for Jordan's daughter, Taylor, to enter with the original partners agreement. Taylor relates how the trio bought the land for their offices years ago in a joint partnership. However, in order to hide assets (one from the IRS, the other from a bad divorce), each partner sold their part of the property deed over to Jordan. So while they may now own the firm, Jordan happens to own the entire ''building.'' Jordan smugly tells his stunned ex-partners they have a week to vacate the premises as he'll be using their space for his new law firm.
-->'''Jordan''': No hard feelings.
* ''Series/OnceUponATime'': Rumplestiltskin's plan to get to the "real" world and find his son ends up backfiring on him when he [[spoiler: ends up trapped in Storybrooke just like everyone else, unable to leave lest he lose all of his Enchanted Forest memories- and therefore his memories of the very son he's there to find]].
** BiggerBad Cora has spent ''decades'' manipulating, abusing, and scheming to satisfy her unquenchable thirst for power and desire to hurt royalty out of revenge for their shoddy treatment of her, a lowborn miller's daughter. This includes using magic to kill Snow White's mother in a slow and painful fashion. Snow White tries to save her mother, and Cora tricks her into taking a black-magic enchanted candle that will save one life by killing someone else. Cora intended to corrupt Snow White in the process. As a child, Snow cannot bring herself to use it and loses her mother. But when Snow White is an adult, has been tormented by Regina (Cora's daughter, and the Wicked Stepmother) for well over 30 years, realizing Cora killed her mother, being ForcedToWatch as Cora and Regina murder her childhood nanny, and realizing Cora's got a scheme in the bag to achieve nearly godlike power by killing Rumplestitskin and gaining his power? Well, that candle ''does'' get used, Rumplestitskin is cured, and Cora's the one who dies by her own magic.
* ''Series/DadsArmy'': In order to clear the rubble from a bomb-damaged pumping station, a process which will be very dangerous for the two people at the front, Captain Mainwaring puts pieces of paper in his hat and marks two with crosses to indicate who will be at the lead. When it comes to Private Frazer's turn, Warden Hodges rudely pushes him aside and takes a piece of paper instead. So of course, Hodges gets one with a cross on it.
-->'''Frazer:''' What a pity; I was going to take that one.
* ''Series/TheInspectorLynleyMysteries'' begins with the bureaucracy of UsefulNotes/ScotlandYard partnering the haughty, aristocratic Detective Inspector "Tommy" Lynley with the cranky, working-class Detective Sergeant Barbara Havers in the hopes that one or both of them would do something outrageous enough to justify sacking them (but preferably her). It [[FireForgedFriends didn't]] [[WorthLivingFor quite]] [[UndyingLoyalty work]] [[TrueCompanions out]] [[LivingEmotionalCrutch that]] [[TheNotLoveInterest way]].
* On ''Series/{{Baywatch}}'', Stephanie is taken prisoner by an escaped criminal. Hiding in the back of her truck, he orders her to drive off the beach. When Mitch radios Stephanie to tell her to return to headquarters, Stephanie starts to say "I have a code--", but the man cuts her off, knowing full well that she could be naming a code that alerts Mitch to her situation. Instead, the man orders her to tell Mitch that she has found a lost child and is driving him around to find his parents. But as this violates lifeguard policy (which is to take the child back to headquarters), it ends up having the very result the man was trying to avoid--Mitch instantly realizes Stephanie's in trouble and sends the cops after her.
* ''Series/{{Banshee}}'' has a literal example. During the shootout in the season one finale, a group of Ukrainian gangsters try to use a rocket propelled grenade to kill the good guys. However, a lucky shot kills the guy carrying the rocket launcher and he squeezes the trigger while the rocket is pointed at a nearby wall. The explosion kills the other gangsters.
* ''Series/HorribleHistories'': At the end of the Greek "Historical Wife Swap", the Athenian man suggests they vote on whose way of life is the best. The Spartan man votes Spartan. His wife votes Spartan. The Athenian man votes Athenian. His wife... doesn't get to vote, she's only a woman!

* In season 4 of ''Series/ArrestedDevelopment'' Gob [[spoiler:plots to get revenge on his rival, Tony Wonder. First he says he's going to make Tony fall in love with him and then break his heart; when he learns that Tony's faking being gay for publicity he decides to ruin his reputation by tricking him into having straight sex on camera. ''Both'' plans rebound on him. He's tricked into having sex with Tony, on tape - just as he becomes President of the Bluth company and is warned to avoid any scandals - and in his [[IHaveThisFriend completely hypothetical situation]] to Michael afterwards he implies he's actually fallen in love, only to later get a voicemail revealing Tony's roofied himself to remove the memory of the previous night.]]
* ''Series/DeadLikeMe'': In a non-villainous example, a flashback reveals that Roxy invented legwarmers and was strangled to death with her own invention by her jealous friend.



* ''{{Series/Fringe}}'' has Harris, the ObstructiveBureaucrat who's been trying to railroad Olivia out of Fringe Division and turns out to have been working in fringe science for quite a while. He's busted when he attempts to weaponize several latent pyrokinetics - and when Olivia shows up to rescue one of them, he locks her in the room with one who's going critical. If she can't direct the energy outwards, then she's useless to Harris's needs, and she'll explode, which will take Olivia with her. Olivia, however, manages to convince the pyrokinetic to focus the energy outwards. Guess who she focuses it on.
** Another example occurs to Alfred Hoffman, TheAgeless Nazi scientist who invents a gas weapon that targets people based on genetic traits. In the climax of the episode, he's preparing to perform an attack on a tolerance conference, only to suddenly fall over dead choking to death from his own toxin. How? Walter used some samples of it to make his own toxin... one that targeted people with Hoffman's exact genetic traits.
* This happens a couple of times in the ''Series/BreakingBad'' finale. [[spoiler:Jesse, having been held captive for months by Todd and Jack, strangles Todd with his handcuffs and breaks his neck. Walt catches a bullet from the machine gun he set up.]]

Kara leaves the building after him, only to find him in the backseat of her car when the timer runs out.
* On the Creator/FoodNetwork cooking competition show ''Kitchen Casino'', the second challenge is called "Kitchen Roulette", in which partway through cooking at their own stations, they will randomly switch and whatever is on the station the new chef ''must'' incorporate into their new dish. It's common strategy for at least one chef to sabotage their station by bringing on a bogus ingredient that is extremely difficult to incorporate into whatever else they're doing, figuring the chances of them getting that station again isn't that good. Cut to the end where sometimes they ''do'' get their sabotaged station back, and ultimately get eliminated for it. Bonus points if one of the judges will actually call them out that they spent too much trying to possibly sabotage their competitors instead of focusing on making a stellar dish like they were supposed to.

As result, the black woman and her three family members and dislocated shoulder lady, who were Sander supporters, voted for Hillary instead to spite him and lose to Hillary.
* The ''Series/CriminalMinds'' episode "Paradise" featured a killer who would murder guests at his hotel, place their bodies in their cars, and place the cars in a blind intersection nearby so they would be hit by trucks and thus [[MakeItLookLikeAnAccident make the deaths look accidental]].

However, he was given immunity for other murders based on being completely honest, revealing where the victims' bodies were so their families could get closure. Therefore his admitting he lied violates it, and with his confession to those murders there's more than enough evidence for a conviction. He's remanded to prison and will be extradited into Indiana, where four of the murders occurred. They also have the death sentence.

* On ''Series/EliStone'', Jordan is nearly killed in an earthquake and the experience changes his view on the world. Jordan decides to change the firm to help those who can't afford fancy lawyers rather than their high-priced (and often corrupt) clients. Rather than join him, his two partners force Jordan out of the firm. They come by as Jordan is packing up his office to give a "no hard feelings" talk only for Jordan's daughter, Taylor, to enter with the original partners agreement. Taylor relates how the trio bought the land for their offices years ago in a joint partnership. However, in order to hide assets (one from the IRS, the other from a bad divorce), each partner sold their part of the property deed over to Jordan. So while they may now own the firm, Jordan happens to own the entire ''building.'' Jordan smugly tells his stunned ex-partners they have a week to vacate the premises as he'll be using their space for his new law firm.
-->'''Jordan''': No hard feelings.
