* ''TheNewAdventuresOfCaptainS'' has the hero constantly beating up enemies inside the world of videogames. When he punches someone in the real world he hurts his fist.
* [[http://www.cracked.com/article_18791_if-movie-characters-didnt-make-horrible-decisions.html This]] Website/{{Cracked}} article lists a number of humourous hypothetical examples, imagining what sort of films fictional characters would watch.
** "An ex-con coach and a team of misfits... No one thought they'd have a chance. They were right."
** Another one why is Ariel from ''Disney/TheLittleMermaid'' [[http://www.youtube.com/watch?v=bYm1GQBgHNk will be a horrible roommate.]] Ariel's CloudCuckoolander personality, her curiousity, and her BuffySpeak not only annoys her housemates but [[spoiler: gets thrown out for her constant singing.]]
* [[http://www.mcsweeneys.net/articles/building-code-violations-for-the-love-shack Building Code Violations For]] [[Music/TheB52s The Love Shack]]
** [=McSweeney=]'s is fond of that sort of thing. Another classic is the report of [[http://www.mcsweeneys.net/articles/back-from-yet-another-globetrotting-adventure-indiana-jones-checks-his-mail-and-discovers-that-his-bid-for-tenure-has-been-denied the tenure committee on Indiana Jones.]]
* ''WebAnimation/HowItShouldHaveEnded'' frequently combines this with FridgeLogic and/or CuttingTheKnot in derailing various movies and such. A few examples include ''Film/TheEmpireStrikesBack'' where Vader could have caught Luke with the force rather than doing nothing when Luke jumped off the catwalk, and the Twilight parody, where Belle gets vamped at the end of the first movie.
* The Prolecto series, at Episode Two and later, falls into this, and at first balances hilarity with reality, but moves towards non-humorous reality later on. For instance, at the end of the first one, they decide to start converting everyone! At the beginning of the second one...[[spoiler: They're in prison for, amongst other things, public nudity!]]
* ''WebVideo/DoctorHorriblesSingAlongBlog'': Near the beginning of Act II, Dr. Horrible gloats about his unstoppable plan to commit a heist using his Freeze Ray. Cue GilliganCut and a bruised Dr. Horrible explaining how he needs to be careful about what he says on his blog because both Captain Hammer and the LAPD watch it.
* The entire premise of the ''WebVideo/{{Smosh}}'' videos, "If X Were Real".
* WereAlive: Angel attempts to use a broken zip line to repel down from the roof of the collapsing Tower, barehanded. The result is he tears up his hands, lands next to the remains of a tanker truck filled with burning diesel fuel, and is left barely clinging to life but slowly dying from his injuries. It's made very clear his injuries would have killed him if Scratch hadn't [[WhyDontYouJustShootHim given him a terminal case of lead poisoning first.]]
* [[http://nequ.deviantart.com/art/Sonny-Gets-Mad-Scienced-144594113 Sonny Gets Mad Scienced]]; a GenreSavvy geek gets kidnapped by a mad scientist for use in horrible experiments that have killed -- or worse -- every one of his predecessors. He's going to use his trope knowledge to break free and save the day before the experiment, right? ... Right?
* ''OrionsArm'' defies RockBeatsLaser by depicting the technologically superior foe (as opposed to {{Insufficiently Advanced Alien}}s) as fundamentally unbeatable by the lower one barring severe extenuating circumstances, [[http://web.archive.org/web/20080414212918/http://www.orionsarm.com/sophontology/intertoposophic_conflict.html going into]] [[http://web.archive.org/web/20080411115346/http://www.orionsarm.com/intro/pluckybaseline.html great detail]] about the trope and why it simply can't work.
* [[http://i3.kym-cdn.com/photos/images/original/000/524/205/0c2.jpg This]] picture shows what would really happen if [[Franchise/SonicTheHedgehog you really ran into gold rings at high speed]].
* In this [[http://www.dorkly.com/video/47881/pokemon-rusty-ep-9-team-rocket Dorkly]] video, Rusty challenges some [[{{Pokemon}} Team Rocket]] goons to a fight. [[spoiler:Team Rocket just shoots Rusty's Pokemon]].
* Ensues in ''{{Literature/Worm}}'' when a member of the ABB tries to use a sword to intimidate and fight Skitter, who controls a giant swarm of insects.
* PlayedForLaughs with one of 1d4chan's home brewed Space Marine chapters, [[http://1d4chan.org/wiki/Reasonable_Marines The Reasonable Marines]]. They act like normal soldiers focusing on stealth and efficiency, trying to avoid combat unless needed, and actually trying to be diplomatic with aliens instead of shooting them on sight. The joke is they are the [[OnlySaneMan only sane group]] in a universe filled with nothing but RuleOfCool and CrazyAwesome lunatics.
* The gif image [[http://www.youtube.com/watch?v=nD0XqFZ8GmI Martial Arts v.s. Modern Arts]]. If you do those martial arts moves in front of a gunman as an IntimidationDemonstration, you're just going to get shot.
* In the ''Blog/WhatIf'' entry [[http://what-if.xkcd.com/29/ "Spent Fuel Pool"]] Randall Munroe explores the physics-based answer to how safe it is to swim in a nuclear reactor's spent fuel pool. Because water is a good insulator against radioactivity it's pretty safe if you stay away from the casks. He then poses the question to a friend who works at a research reactor.
--> '''Randall's friend:''' In ''our'' reactor? You’d die pretty quickly, before reaching the water, from gunshot wounds.
* ''WebVideo/ASDFMovie'': In the second episode, a bear named Desmond is briefly seen, wondering how he got on the moon. In the seventh episode, we see him again. [[spoiler:He's dead. No air on the moon, you know.]]
** In the fourth episode, aliens attack. A onlooker heroically yells, "Throw! The! '''CHEESE!'''" He throws a ton of cheese... and it all just bounces off the spaceship.
* The story of the first owners of [[SCPFoundation SCP-]][[http://www.scp-wiki.net/scp-1958 1958]]. All but too excited to have a bus that can travel in space, they set off to colonize the stars...neglecting the fact that it still goes at the same speed of a regular bus, and their destination was ''lightyears'' away. They realized it when, after two months of travel with the crew dwindled and nearly starved to death, they realized [[OhCrap they barely made it to the Moon]].
** One of the general themes of SCP is pointing out the horrific consequences of characters and plot devices with fantastic abilities, powers, or properties. A good example is the Keter-class [[http://www.scp-wiki.net/scp-871 SCP 871]]... self-replicating cakes.
* ''Roleplay/DarwinsSoldiers'' has a quite few examples:
** If you do massive damage to a top secret military base in the process of saving it from a terrorist assault, you will suffer severe consequences.
** [[spoiler:Dr. Branston]] was shot in the leg and later dies from his injury.
*** Same for [[spoiler:Hicks]] and some unnamed sniper.
** Air vents are cramped and [[AirVentPassageway using them as passageways]] will make a lot of noise.
*** Air vents in a top secret military base will be too small for someone to fit through.
** Being made of solid metal grants NighInvulnerability...and a total inability to swim due to your increased density.
** TheBerserker will end up with convictions for assault and/or spend time in the hospital.
** Throwing someone [[DestinationDefenestration through a window]] will severely injure or kill them.
** InterspeciesRomance will ''never'' result in children.
** [[spoiler:[[SnakePeople Sergeant Larry Masters]]]] eventually dies of lung cancer bought on by his habit of smoking.
** [[spoiler:[[MindOverMatter Siberys]]]] shows what happens if you quickly cobble together a vaccine/drug and use it without proper testing and/or followup. The vaccine he took works as intended but [[spoiler:he dies from the complications several years later]].
** [[spoiler:Chris [=MacLean=]]] shows what the stress of being responsible for someone's death as well as keeping a deep secret for decades can do. He [[spoiler:[[DrowningMySorrows becomes an alcoholic]] and later dies in an alcohol related accident.]]
* Quackerjack attempts to do a SadisticChoice in episode 6 of ''WebAnimation/{{Ducktalez}}'' with a pair of gondolas as a reference to Film/TheDarkKnight. However, the criminals blow up the gondola with the civilians 3 seconds in.
* [[http://spinpasta.wikia.com/wiki/Jeff_the_Killer:_Rewritten This]] take on the ''WebOriginal/JeffTheKiller'' creepypasta shows about how well a teenager with grievous recently self-inflicted facial injuries like massive incisions to the face and burned eyelids would fare as a killer. [[spoiler: He fails to kill his last two intended victims, and his wounds become severely infected, resulting in sepsis and death.]]
* The ProtectorsOfThePlotContinuum have a room dedicated to making this happen to Sue-perpowered and ill-thought-out OC's. Drank twenty-two bottles of rum in a short span? The Reality Room gives realistic effects on the body. A military recruit with a disdain for authority? DrillSergeantNasty is only the beginning. [[TooDumbToLive Sue made passionate love shortly after a severe flogging]]? Hoo boy.
* [[http://www.youtube.com/watch?v=0rh9LO6VkZk Mario Kart 8 is Great]] starts with the Mario and friends getting ready to race underwater. However, as soon as the green light flashes, [[spoiler: they have already drowned and their bodies are shown floating on the surface]].
