Somehow, I don't think you thought your cunning plan all the way through.
Mr. Krabs: Plankton! You knew I would never distrust a dollar! Plankton: That's right, Krabs! Now hand over the Krabby Patty secret formula! [Beat] Mr. Krabs: Or what? Plankton: I don't know. I never thought I'd get this far. Mr. Krabs: Well then, allow me to suggest your next move. [Mr. Krabs flushes Plankton down the toilet]
A situational trope. One character will develop a plan designed to solve a certain problem they're encountering. However, due to their failure to plan ahead, there is a massive gaping flaw in their plan that they, and also perhaps the audience, missed. As a result, they are now in a situation where, rather than winning, they are stuck with either a stalemate or an outright loss. As indicated by the page quote, this may occur because the character never thought that their plan would actually progress as far as it did in the first place.
A more comedic, simple version of Didn't See That Coming. See also And Then What?, when the flaw is not knowing what to do if the plan succeeds. If the person pointing this out is sufficiently annoyed, this can lead to What Were You Thinking?. May also lead to a This Is Gonna Suck for the schemer when he realizes how screwed he really is.

Vegeta during the Saiyan battle in Dragon Ball Z after Gohan turned into a Oozaru. Escaping being crushed multiple times, he did seem proud of himself for a moment after cutting off the boy's tail, thus shrinking him to normal size. Given that, while Vegeta has taken a considerable beating fighting the various heroes, Gohan was the last one strong enough to present any kind of threat to him, it seems that he's won. Then comes the brief realization that Gohan is still semi-gigantic, not maintaining his place in the air and now falling towards him while semi-gigantic. All of this happens in about a second, leaving Vegeta no time to dodge. Not long after a crushed Vegeta is sitting in a crater, struggling to crawl to his ship.
it's a running theme in this series that various character usually don't think their actions through, and end up suffering for it.
Almost happens in Mahou Sensei Negima!. The cast are discussing ways to retrieve Asuna and the Great Grandmaster Key from the Big Bads, and get the idea to use Natsumi's artifact (which makes the enemy completely unable to sense your presence) to get close for an ambush. Unfortunately The Anti-Magic field coming from Asuna would make that plan useless. They almost go with the plan until Ako realizes the flaw. Cue Yue coming up with a workable solution, and a Crowning Moment Of Awesome for everyone involved.
One Piece has the "Fake Straw Hat Pirates" based in Sabaody Archipelago after the time-skip. Since Monkey D. Luffy has attained even more infamy than ever before due to his part in the War at the Summit, one guy going by the name "Three Tongued" Demalo Black got the bright idea of posing as him and setting up a crew to pose as the Straw Hat Pirates, usually getting his way by relying on Luffy's fame to threaten people and recruit fearsome pirates into his crew. Unfortunately, around the time they were recruiting, the real Straw Hats came back, and it got steadily worse when they try to recruit a pair of Ax-Crazy pirate captains who intend to kill the Straw Hats for more fame, and then Marines show up with Pacifistas, with a Marine Captain personally knocking out Demalo Black with his axe for trying to talk smack to him while pretending to be Luffy. Because he forgot when you're one of the most infamous pirates on the planet, lots of actual strong people want to kill you.
During the Paramount War, the heroes expend an extraordinary amount of effort to get Luffy to Ace's execution platform. Only after he gets there does he, and everyone else, remember that Sengoku is standing right next to their goal.
At points in both the first and second seasons of Strike Witches, Minna pulls a gun on Mio in order to try to stop her from getting herself killed in battle. Mio is quite aware of the flaw in this bluff, and it doesn't work either time.
Harumi Kiyama in A Certain Scientific Railgun plays this both ways. On the one hand, she's the only villain who realizes the damage her plot is causing, and actually creates a way to reverse the effects harmlessly once she's finished. On the other hand, she failed to account for what would happen if people randomly fall into a coma—such as if they're driving a car.
In Girls und Panzer, the Oarai student council revives its Tankery program in order to compete in a national tournament which is a lie to cover up the fact that the school will be shut down, but they have made a deal to prevent that if they win. Unfortunately, the student council overestimated how many tanks they had left over, i.e., the ones they weren't able to sell, assuming that the school would have many in reserve from its past participation in tankery. Student Council President Anzu admits that her assumptions were faulty, but she couldn't think of any other way to keep the school open, and at least wanted them to have hope.
In episode 3, with it raining harder and harder, Rize says she'll call for a cab to take Sharo home. Chiya, remembering Sharo exclaiming she didn't want Rize to know where she lives, instead volunteers to take her. However, she attempts to carry her home, and collapses a short distance from the Rabbit House.
In episode 7, the girls work on a large jigsaw puzzle. As they get closer to finishing it, Chiya asks where they're going to place it. The girls are then stumped because they didn't consider what to do with it when they were done. In the end they have Chino's father put it up in the coffee shop to replace another picture of a rabbit.
In the climax of Northwest Passage, Montclave reveals critical information to Simon in the hopes of permanently turning him against his father, Charles Lord. The information is that Simon's parentage is a Luke, I Might Be Your Father situation, since Montglave raped Simon's mother at the time of conception. Unsurprisingly, Simon takes a rather dim view of this knowledge and promptly blows Montglave's brains out.
Batman villain Warren "Great White Shark" White successfully pleaded insanity to escape embezzlement charges. He was sent to Arkham and wound up at the mercy of Gotham's worst psychopaths. Oops.
Doctor Octopus's plan in the Spider-Man storyline Ends of the Earth. With the evil doc dying, Doc Ock plans to flash-fry the Earth, leaving approximately .08 percent of humanity to live on and remember him as the greatest monster that ever lived. However, Spidey points out a glaring flaw in this plan: they'll live. Brain dead, their brains flashfried, too. Doc Ock flips.
In one issue of the Batman: The Brave and the Bold comic, Nightwing leads the Robins from other points in time (Jason Todd, Tim Drake, Stephanie Brown, Damian Wayne and Carrie Kelly) to one of Ra's al Ghul's bases in order to use a Lazarus Pit to save Batman's life. When they encounter the League of Assassins, Damian leaps out, demanding that they stand down as is his birthright as an al Ghul. The assassins look at each other, then charge at the Robins. Damian then remembers that he's not born yet.
In an episode of Bruchbach Serenade, Rick has just finished his summer job at city hall. In order to maximize his earnings, he had made the mayor give a speech that made fun of the audience and incorporated Nazi phrases, so he could sell the audience rotten tomatoes. Now the people in charge refuse to give Rick a certificate for the job.
In Runaways, during their first battle against Excelsior, Chase Stein decides to create a distraction by attacking with the Leapfrog's lasers... which quickly drains the Leapfrog's batteries, forcing the Runaways to flee with their highly distinctive vehicle fully exposed (because without battery power, they can't activate the vehicle's stealth mode) making it easy for Excelsior to track them down.
During the Civil War arc, Jennifer Walters was outed as She-Hulk (again) by a New Warriors hate site. On the way into her office through an angry mob to help some former New Warriors keep their identities hidden from the public, one of the mob recognized her, grabbing her by the arm and ripping her shirt, proudly exclaiming "I've got She-Hulk!" Jen shifted and hoisted the guy up by his lapels.
She-Hulk: Alright, you've got She-Hulk! Now what?!
Angry Citizen: I. . . uh. . . guess I didn't think this through. . .
Voldemort Goes Back To School: in a state of panic, Voldemort creates massive wards on an abandoned classroom door that only Dumbledore or Grindelwald could hope to break in the hopes of avoiding further interactions with Harry and Draco. He realizes the gaping flaw in his plan when he begins to worry that McGonagall might get around his wards if she were to transfigure the door into something else and as it is Harry circumvents the door and all of his carefully laid warding altogether by dropping in through the window on his broomstick. And because he's so heavily warded the door he's essentially locked himself in.
One of the antagonists of The Nuptialverse story Families is an Immortality Seeker who riled up a huge anti-Princess group and took Twilight Sparkle and Rainbow Dash, among others, hostage in order to force Princess Celestia to divulge the secret of her and Luna's immortality. Celestia's response is to laugh in his face and point out all the holes in his plans, such as having no way to avoid royal retribution after everything was done, almost certainly not having Power Limiters strong enough to hold Twilight, and (accurately) stating Rainbow is useless as a hostage because she would never want Celestia to risk all of Equestria for her sake alone.
First Try Series has Sasuke realizes this during his confrontation with Itachi during the Search for Tsunade arc. Namely Sasuke notes that Itachi used to be in ANBU before becoming a criminal on the run and he's been a Genin for little over six months. Right before he gets hit with a Tsukuyomi he says the trope name verbatim.
Neji in The Darkest Light realizes this after he tries to have Hinata "manhandled" by hiring Naruto/Naruichi to give her a massage. Not only does Naruichi have an acceptable explanation for what Hiashi walks in on, he also has the receipt saying he was hired by Neji.
In Of White Trees And Blue Roses, Rhaegar's abduction of Lyanna blew up spectacularly. Also, the Knight of the Laughing Tree participating in the Tourney of Harrenhal.
Oops has this happen for Harry's (accidentally made) horcrux. It gets Harry to brew and drink a luck potion of the "May you live in interesting times" variety by making him think it was a good luck potion. After Harry calls the horcrux out on not only how messed up his luck usually is but that he's already in Britain during World War II, the horcrux admits that it didn't think things through but in its defense, Harry rarely does either and it is a portion of Harry's soul.
Webwork: The Youkai races all fled to the dimension known as the Emptiness in order to escape humanity's growing dominance of Japan. However, the Emptiness was lacking in food, and all the Youkai were too chaotic to coexist without humanity as a common enemy, so they all ended up turning on and feeding off of each other.
The Iron Giant: Mansley, single-mindedly obsessed with destroying the Giant, personally orders the Nautilus to launch a nuke at the Giant after the military realizes he tricked them, failing to realize at that moment that the missile was locked on to the Giant's current location; as the Giant is standing right in the middle of Rockwell at that very moment, the nuke will take out the entire town, including Mansley himself, when it hits. Fortunately, the Giant intercepts the nuke itself and saves the town.
In Aladdin, Jafar is defeated when Aladdin tricks him into wishing to become an all-powerful genie. Jafar either forgot or was not aware that genies in this setting are bound to a magic lamp and obliged to grant wishes by nature.
Or because of the fact that nobody told him about snowdays, which would probably become the new summer vacation anyway.
Kung Fu Panda 2: Po's plan to rescue the Furious Five where he admits he hadn't thought what he would do when he got close enough to do that. Mainly due to the fact he didn't expect to make it this far.
In Monty Python and the Holy Grail, when King Arthur's knights attempt to copy the Trojan Horse ploy with a giant wooden rabbit, none of them remember that they're supposed to get inside the rabbit until after it's been taken into the castle.
Of course, given the French knights' predilection for catapulting just about everything they can find, actually getting into the rabbit would have been even worse.
In It's a Boy Girl Thing Woody (in Nell's body) decides to get her a reputation for being easy. So he decides to have her sleep with this really sleazy guy. The Didn't Think This Through example occurs just before the deed is to be done when Woody realizes that he is actually going to be the one to experience the drunken sex with a guy. Also counts as an Oh Crap moment.
In Pirates of the Caribbean Elizabeth stabs her host/captor captain Barbossa with a knife. It somehow slipped her mind, that even if she'd succeeded, she would still be on a ship full of vicious pirates, whose captain she just killed, in the middle of the raging sea. Lampshaded by Barbossa: "I'm curious. After killin' me what was it you were plannin' on doin' next?"
Dog Day Afternoon practically runs on this. It was supposed to be just a quick bank robbery. But Sonny - the so-called mastermind - never thought to double check the information about the cash shipments. The vault's supply has already left for the day, and there's almost nothing left. Sonny attempts to black out the security cameras (he was too short to really reach them) only after the robbers had been inside, unmasked, and glove-less for nearly five minutes. Then he tries to cover his paper trail by lighting the traveler's check register on fire...which causes enough smoke to alert people outside that something strange is going on. He didn't think far enough ahead to consider hostages, getting a full layout of the building, the possibility of one of his cohorts backing out of the plan a few minutes in, or that his remaining partner was too psychologically unstable to handle the ensuing standoff with the authorities. He even tells people his real name, his background as a bank teller, and his service in Vietnam, thus making it very easy for the authorities to figure him out. These problems are just the start of Sonny's horrendously botched heist and his desperate attempts to get everyone out of it alive.
In X-Men: First Class, Sebastian honestly believes that he can convince Erik to join him, despite having murdered his mother to activate Erik's powers, and knowing that he has spent his entire life hunting him down. Magneto even says as much:
Some soldiers open fire on Godzilla in Honolulu. They quickly realize the pointlessness and give a face that says this trope.
The female cocoon is taken to a nuclear deposit. Serizawa realizes that was a mistake when checking the data for the male's communication.
The military underestimates the speed of the male and it makes it to the nuke well before it goes off. The nuke is taken to the middle of the city and a plan has to be hatched to get it out.
The Hobbit: To enable the dwarves to escape from the Wood Elves, Bilbo secures them inside barrels so they can float away downriver. Unfortunately:
It was just at this moment that Bilbo suddenly discovered the weak point in his plan... Of course he was not in a barrel himself, nor was there anyone to pack him in, even if there had been a chance!
Not that being packed into a barrel himself would have been an improvement. Getting out again wouldn't have been easy.
Not to mention the entire journey itself. The one weak spot in the dwarves' scheme to get their gold is that Smaug is still sitting on it, and a baker's dozen of dwarves are no match for the dragon, which is why Gandalf insisted that they rely on burglary. However, Bilbo, seeing the size of the hoard he's supposed to steal, states that they should have brought an army of burglars, as there's only so much he can steal at once. Then Smaug smugly asks Bilbo how he's supposed to get his share back home. Only a series of lucky breaks (for a given definition of luck) keeps the adventure from going to waste.
The movie works around this by planning to have Bilbo fetch the Arkenstone, which can be used to convince all the armies of the six other dwarven settlements to come to Thorin's aid.
Twice in Kitty Goes to Washington. Kitty had good reason to banish Elijah Smith back where he came from, but she didn't consider that this would mean the collection of vampires and lycanthropes under his control would then be out of control. Cue chase scene, followed by calling in backup to deal with the fallout. Later, Kitty tries to distract the guards on the first floor of a building by throwing rocks at the upstairs windows, hoping they'll investigate the crash. She realizes belatedly that if they instead put two and two together and look out on the street, she'll get caught red-handed. (Luckily, they're typical guards.)
In the Knight and Rogue Series, when told he must, in order to regain his legal rights, capture a murder suspect he released from jail and become his brother's steward, Michael sets out to bring the criminal to justice. Upon learning she's innocent he decides to not even bother with bringing her to trial, opting to be tattooed as a horrible criminal instead. It's not until afterward that he realizes this will make people hate him by default and take advantage of him due to his being unable to go to the law for help. Bonus points for his father forcing the situation on him in the hopes that only his oldest son will hire Michael for a stable job if he's marked, as he apparently didn't notice that Michael spent the whole past year funding his adventures by stopping for the day in random towns and doing odd jobs for people who don't need to see the area on his arm where he gets marked.
Harry Potter and the Chamber of Secrets: The Trio devises a plan to impersonate students from House Slytherin, so that they can sneak into the Slytherins' dorm and hopefully uncover some information about the titular Chamber. They spend a month concocting an extremely advanced shapeshifting potion, and make some thoughtful arrangements, like stealing appropriate robes and preparing drugged cupcakes to put said students out of commission for the duration of their foray. Finally, everything is ready, and they perform the transformation... whereupon they realise that they have no idea where the Slytherin dormitory is.
In the same book, Harry and Ron miss the train to go to Hogwarts, and in order to get there they steal Mr. Weasley's flying car. They promptly get seen by about seven Muggles across England. As McGonagall points out to them, they had an owl and perfectly legitimate reasons to be late, so they could have just sent a message to be picked up.
On Stephen King's short story The End Of The Whole Mess, this is Bobby Fornoy'sFatal Flaw. His brother reminisces when he was a child and developed a glider, not figuring out that the backwoods of his house were too dense to fly such a thing until he's high in the air and ends up crashing. The story itself showcases Bobby finding out a way to create world peace via a natural water-borne calming agent he discovered... and not detecting until it's too late that the agent triggers early-onset Alzheimer's. Oops.
One Relativity story has, in the climax, all of the heroes trapped at the top of a "parachute" carnival ride. Dark Flame suggests they each get into a gondola and cut the cable, and then they'll be lowered safely to the ground by the parachutes. It isn't until after her cable is cut that she realizes that it's just a carnival ride, the gondolas were designed to be lowered by cables, and the parachutes were just decorative.
Live Action TV
In The Wire, Detective McNulty's cunning plan to fake a serial killer in order to get money for an investigation into a murderous drug crew becomes a textbook example of this. Although command showers him with resources, people gradually get wind that he's giving overtime out to people for different cases, so he ends up getting blackmailed into giving people overtime to go and play golf in Florida. Because the eventual bill runs into the millions, McNulty makes himself liable for not only firing, but serious jail time. Because the case becomes a political football, he ends up having to bullshit the entire police command staff and all of city hall. And because McNulty hadn't thought what he'd do when the drug crew were busted, leaving him with a non-existent "serial killer" to catch, he ends up having to find a way to de-escalate the thing rapidly. For a while, you think he'll manage to stay on top of things. He doesn't. The wheels come off. Spectacularly.
An episode of Blake's 7plays this for laughs with its justification: when Vila asks Tarrant if he can actually dock their tiny ship into the Liberator that they have just reclaimed from Servalan, the following exchange occurs. (Incidentally, it's just a throwaway gag, since the very next scene has them already back on the Liberator safely.)
Spike schemes to both break up the Scooby Gang and plant evidence to lead Buffy into a trap. It takes the Big Bad he's working for to point out that he's given Willow the evidence, and Willow won't be speaking to Buffy now.
Apparently, when she had Willow activate all Slayers worldwide, it never occurred to Buffy at that moment that not all of the newly empowered Slayers would be willing to use their powers for good, with one Slayer in particular, Simone Doffler, becoming a terrorist and obsessed with killing her.
In the Doctor Who episode "World War Three", the Slitheen get into 10 Downing Street, and chase the Ninth Doctor, Rose and Harriet Jones. The Doctor activates a defence mechanism that means there is 3 inches of thick metal between them and the Slitheen - or any way of escape.
The Doctor: They'll never get in.
Rose: But how do we get out?
The Doctor: ... Ah.
In a Saved by the Bell episode, Zack has detention on the day of a trivia contest for a trip to Hawaii. He sends Screech in his place, who comes back to ask him a question. Mr. Belding explains only those in detention can talk to others there, so Screech purposely gets in trouble. When he sits down, Zack tells him the obvious problem with that plan.
On an episode of Seinfeld Kramer is at a department store when he decides to sell the clothes he's wearing to another customer. When he's left naked in the store's changing room with nothing to put on, he whimpers, "I didn't think it through!"
Kramer does this kind of stuff a LOT. Like betting that he would turn his apartment into a triple tiered deck.
In an episode of Top Gear, there was an amphibious car challenge, Hammond's car looked like a boat (with the steering wheel near the back) with an upper portion for the "girls in bikini to go," which he then noticed was so high up he couldn't see over while driving.
Then came Jeremy Clarkson's mobility scooter in Season 18, which was arranged so that the drive wheels had nothing actually pressing them against the ground.
The motorhome challenge: Clarkson designed a three story home on top of his car. It was barely able to clear overhead passes, and proved to be top-heavy, nearly tipping over several times on the road, and finally did during a very windy night.
None of their cop car vehicle-stopping devices proved well planned. Richard neglected to consider that cars can turn; James neglected to consider that cars have windscreen wipers; and Jeremy neglected to consider that a car's axle can handle only so much stress. The net result was that none of them managed to stop the Stig and as an additional bonus one of Jeremy's wheels ended up a substantial distance from his car.
The Big Bang Theory shows Leonard trying to slip out to meet his then-girlfriend and getting Sheldon to cover for him. Given that Sheldon cannot do this convincingly, Leonard almost immediately wonders why he didn't think this through.
(Also counts as a Real Life example) The Tonight Show - Johnny Carson would often have non-celebrity regular folks as guests (often the most interesting and entertaining part of the show) - one was a self-styled "idea man" who came up with get-rich schemes, none of which really panned out. He had high hopes for his latest - shaving his head and painting advertising on it (this was way, way before shaved heads were commonplace). Johnny commented that, coming on this show, he must have been able to charge some pretty high rates - and the guy froze...he never thought of that. Johnny tried to keep the tone light, but the guy spent the rest of his time there looking like he'd swallowed a foul-tasting bug.
In one episode of 30 Rock, Kenneth pitches an idea for a game show he had to Jack: a show like Deal or No Deal where the contestants must find out which briefcase has a million dollars of gold inside. While filming it, the contestants only need to look for which model is having difficulty holding her briefcase. The show is then quickly canned. Kenneth even lampshades it:
"Ooooh, gold's real heavy, innit?"
In the opening to an episode of The Suite Life of Zack and Cody, Zack wins a bet against his brother, Cody, and now the latter owe him smoothies, which he now has to make.
Zack: Did not think that through.
In the season 8 finale of Scrubs (J.D's last day), Sunny helps trick Dr Cox into admitting he thinks J.D is an exceptional person - within earshot of J.D. Once Cox is done gagging, he has this to say:
Cox: You realize that even though he gets to leave, you have to stay?
Sunny: I didn't think that out.
Cox: No. Ya didn't.
Rome. Brutus and his fellow conspirators kill Caesar, justifying it by declaring him a tyrant. However Marc Antony points out that if Caesar is a tyrant, then by Roman law all his previous acts are void, including the appointment of the conspirators to their positions of power. Rather than risk an election (given that Caesar was well thought of by the common people) they're forced to make a truce with Antony (giving him time to rally the mob against the conspirators with his Rousing Speech at Caesar's funeral).
Have you heard the story of Bottleneck Bob? He tried to rob the train with cattle, but evidently forgot they needed to be corralled somehow: "The cattle ran all over the place / And there was Bob with the longest face"

The major flaw in his scheme doesn't occur to him until just before he goes over the edge...
About midway through BioShock Infinite, Booker makes a deal to get an airship out of Columbia, which in fairness was done right after he woke up from being bashed unconscious.
Elizabeth: (incredulous) You can get us out of here?
Booker: Yes! I just need to... (audible wince) supply enough weapons to arm an entire uprising.
After Booker and Elizabeth risk life and limb to get to gunmaker Chen Lin's impounded tools, they realize that the "tools" are more like machines — way too big and numerous to be transported anywhere, let alone all the way back the way they came from the shop.
Booker: Well we sure as hell aren't gonna be able to carry all this back to the shop. God we didn't think this all the way through...
In Kingdom Hearts: Chain of Memories, Larxene is trying to cheer Namine up about the plan. Namine replies that they want part of Kairi to replace Kairi in Sora's memories so that he'll forget Kairi. Spot the flaw in this plan.
Something you can do in Smackdown vs Raw 2011 ladder matches. Have you and your partner both climb up a ladder. The opponents get up and realize they could just tip the ladder over. Cue doing just that.
In the Mass Effect 3 Citadel DLC Shepard is targeted by someone who wants to be Shepard. No, not Conrad, it turns out a plan to kill and replace Shepard by a Shepard clone. Turns out they're a Bad Boss, worse than pure renegade Shepard and a xenophobe. If the idea is to become the legend then they'd need to gain crew loyalty for the suicide mission, follow the paragon path Shepard had only to find out they're hosed upon learning Shepard's love interest is an alien.
In general, this is the Fatal Flaw of the Salarians. Their short lifespans seem to make it hard for them to think out their actions on a long-term scale.
He later hires you to go kill people with Torgue guns so he can use footage of it in an advert for Torgue guns. A radio advert. This time he doesn't realize it.
In Star Wars: The Old Republic, the Republic has a top-secret prison on the planet Belsavis, where they send people who will never be allowed back into the galaxy again.

Eventually, these descendants started a movement to gain their freedom, which left them open to the Empire's offers...
In the bonus route of Puella Magi Madoka Magica Portable, Homura spends all her efforts to save everyone individually from their despair and/or death, and prevent Madoka from making a contract. Great! Then Walpurgisnacht shows up, and they're not ready to fight her as a team. Homura gives up and bails before the battle even starts.

When you finally succeed, you see the world explode from your space pod.. and are then offered a small menu of cheesy lines you can say with no-one to hear you and your oxygen running out.
This is more or less the defining trait of Wheatley in Portal 2. As a particular example, in one scene after Chell escapes from a deathtrap, Wheatley calls to her to come back. If you actually go back, Wheatley realizes that he cannot reset the trap and he has no other trap prepared, and apologetically resorts to asking you to throw yourself down an obvious pit.

An early strip of Sluggy Freelance starts off with Riff and Torg talking about how Zoe has a date with this guy she has a huge crush on. Riff then mentions that he is going to visit his ex-girlfriend Gwynn at her apartment, which she shares with Zoe. Torg is surprised that Riff going to see her alone like that. Riff insists that they're not alone, that Zoe will be there... at which point he realizes that even though he was aware of both of these pieces of information he only just now realized that they were related.
Female Immortal: I hate being invisible and intangible; it feels like cheating. Male Immortal: We can't exactly claim to be "everyday students" and expect to pass unnoticed in Elliot's house. Female Immortal: We could pretend to be burglars! That would make sense, right? Male Immortal: ... I don't think you've thought this through...
Abraham. Almost everything he ever did and we know about, starting from an enchantment Gone Horribly Wrong for which he became infamous. He (among other things) swore to destroy every creature created by his botched enchantment, the Dewitchery Diamond, on the assumption that the Diamond would be used against curses, thus creating monsters. He hadn't accounted for the Diamond being used to rid people of relatively harmless conditions such as Elliot's use of it to cure his Gender Bender problem by creating Ellen, an (mostly) innocent Opposite-Sex Clone. At one point, he claims he did everything he could to destroy the diamond, which failed. Within ten seconds, someone is able to think of something he didn't: Chuck it into a volcano. Maybe it wouldn't work, but c'mon, it didn't even occur to him? Even if that didn't destroy it, nobody's going to be able to use it for a good long while.

The Anarch: I may have made a slight error in my calculations. Punchline: When you were adding up the numbers, did you remember to carry the stupid? The Anarch: Yes! ... no.
In Schlock Mercenary, the UNS tries to use a court case to trick a nearly all-powerful AI into admitting that he has been performing morally questionable actions (specifically, "disappearing" problematic people).
Kerchak: And then what?
Breya: I... haven't thought that far ahead.
Kerchak: I'll bet you a bushel of pureed bananas he has.
In The Wotch, the Uricarn Demon killed all the other members of his species. He didn't think it through.
Uricarn: I enjoy being your bit of controlled chaos. Beats just wandering aimlessly finding cheap thrills like I was doing after exterminating the rest of my kind... Which was kinda stupid in retrospect. Probably should have let myself grow up a bit before making that decision...*
In Commander Kitty, Nin Wah tries to turn herself over to the Triple-I by teleporting herself to one of their ships... while CK is busy shooting them down.
In Questionable Content, Angus, Marigold, and Faye get drunk together. Faye asks Marigold if she has ever dated anyone (she hasn't). She says that she think she has a chance with someone and looks at Angus as he returns to the couch. Faye, feeling incredibly awkward walks out and goes home. Thing is, Angus likes Faye (which Faye knows) and Faye may like Angus. Angus doesn't like Marigold like that, but she left them together drunk and alone. When Dora points out the obvious, Faye has the appropriate reaction.
In Ménage à 3, during a Girls' Night Out Zii notices that every man in the bar is buying DiDi drinks and decides to intercept them. Problem is that she does so by drinking them down herself, not the best move especially considering that DiDi has at least 50 pounds on her.
The first story arc of The Inexplicable Adventures of Bob! climaxes with Bob volunteering to save Ahem by fighting a monster. He reassures Voluptua: "Trust me, I know what I'm doing!" The monster appears, and it's a horrific thing with mandibles bigger than his whole body, and he realizes suddenly, "No I don't!"
8-Bit Theater - During their battle with the Lich King, the Light Warriors manage to remove his soul from the earth orb - and then realize they have to get it back in him.
Red Mage: In other words, we've only succeeded in making the invincible king of death even angrier at us.
Thief: Y'know, I really hadn't planned this far ahead in the scenario. I presumed we were going to be dead about five minutes ago.
In The Salvation War, after the demonic general Abigor hears of the defeat of (most of) his cavalry attempting to charge a ridgeline with "cowardly mages throwing mage bolts, with mage-bars in the ground and silvery snakes in the ground that cut up demons and their steeds alike" (paraphrasing here), his plan for the second day of fighting is to extend his lines by thinning them — by the time he was done, an almost-fifteen-mile-long front! — so as to outflank and envelope the enemy, while ordering massed use of demonic bolt "fire" to suppress the mages. Too bad he didn't realize that he would only be able see a small portion of the battle at any one time, and thus would have to keep riding back and forth along the lines, until he was already on the front lines in the midst of the carnage, with multiple rockets headed his way... they missed him, but he immediately and correctly intuited that he had been personally targeted.
Kevin Murphy puts the exact phrase into the mouth of the Scott Ian-looking Geat who makes a spectacularly failed attempt to charge Grendel in the 2007 Beowulf RiffTrax.
In Dragon Ball AbridgedGohan suddenly realized mid sentence that his decision to challenge Recoome to a fight after Recoome had already wiped the floor with Vegeta, a much more powerful fighter, was a bad idea.
Gohan: I'm not going to back down. I might be younger than you, smaller than you, weaker than you, and much less experienced, but I learned more about peach farming than yo-I think this was a horrible decision. Recoome:Recoome agrees.
In Dead Zone Abridged, Garlic Jr's plan was to have his minions kill Kami to avenge his father...then use the Dragon Balls to become immortal.note For the unfamiliar with the show, the Dragon Balls' power is tied to Kami so if he dies, they no longer work After Kami points this out, Garlic is honestly surprised and is glad his minions are "so incompetent".
Later on, he tries to kill everyone by summoning a portal to the Dead Zone... i.e. the perfect prison for an immortal like him. When the plot is revealed to be a movie pitched by Krillin, the latter admits he had "written [himself] into a corner with the whole immortality thing".
The plan that Leeroy's raid group comes up with for taking on the Rookery in the Leeroy Jenkins Video ignores two key facts:
Scattering the whelps of the Rookery only keeps them off you for a few seconds and will likely bring more to bear on you — you really want to hatch as few of them as possible. Fear rotation is rather pointless in the Rookery anyway due to the rate at which the eggs respawn.
The paladin ability Divine Intervention does not allow a protected character to use any skills and is very much wasted on mages (who primarily rely on skills such as AOE attacks) and has the added "bonus" of killing the paladin who uses it, removing a character with the ability to tank and heal from the general fight.
Marble Hornets: Half of what Jay does. For example, breaking into Alex's home. He drops his flashlight, and then runs into the Operator.
Light: Wow, a book that drives people crazy when they touch it! (*touches the notebook*) Death Note? What is this like an advanced calculus notebook or something? I'm so gonna walk around and touch everyone with this and drive 'em... oh, right. I didn't think this one through.
Also in 'Beach Brawl' when Kerry impulsively throws Shovel at frozen Cell, thinking that would shatter him.
Bear: "Even I saw that one coming a mile away."
Lampshaded in thisOccupy Richie Rich post, where Richie demonstrates a button-activated safe-opening system - and the button is not protected at all.
"richie m’boy I don’t think you thought this through very well"
At the beginning of Achievement Hunter's GO! series, Geoff reveals that he would pay for a pizza party for every person who gets five wins. By the end of the twelfth episode, the scoreboard is reading 3/3/2/2/2 and Michael points out that, pretty soon, he's gonna be hosting back-to-back pizza parties. Geoff just looks at the scoreboard in total disbelief.
In one episode of Justice League, Copperhead attempts to gain leverage for an escape by jumping onto Hawkgirl's back, positioning his poison fangs near her neck, and ordering her to fly him out. She flies up a few hundred feet and stops. When Copperhead demands to know why, she notes that his threat is no longer as effective, since if he bites her neck she'll fall to the ground and they'll both die. "Didn't think this through, did you?" After she touches down, Green Lantern congratulates her on the bluff; her reply is a deadpan "Who's bluffing?"
Zim has this as a personality trait; as The Other Wiki once described him, "Zim has a crafty sort of intelligence, but he tends to think precisely one step ahead of his current problem". For instance, Zim builds a stasis-field device in one episode which subsequently explodes, but the fireball is slowed by the stasis field until it's expanding at less than walking pace. However, it will eventually grow to the point where it'll consume Zim's base along with the entire city. The Tallest might call back soon and Zim really doesn't want them seeing an embarrassing screw up like this (though they don't really give a crap). Basically Zim has to get rid of the explosion, do it in a way that doesn't destroy his base, and do it quickly. Zim's brilliant plan to handle this problem? Simple. He'll just cancel the stasis field under the assumption that once the field is canceled, the explosion will be gone forever. This true, but this will also annihilate his base and the whole city. Despite being warned by his computer, and even his Cloud Cuckoo Lander sidekick, that this is a really, really bad idea, he goes ahead with it. Hilarity Ensues.
Family Guy: In the episode "Blind Ambition", there is clip of one of Peter's (or both his) Siamese twin ancestors each fighting opposite sides in the Civil War. The one who fought for the Union killed the other, who continued decomposing until he was a skeleton. "Nope... Did not think that one through," he said to a bartender who asked about the skeleton.
American Dad!: The episode where Francine gets poorly-aimed Laser-Guided Amnesia, she runs off to Burning Man with Hayley's boyfriend. This exchange happens when Stan meets up with Hayley at Burning Man:
After Roger releases a bunch of murderers to make Stan's haunted house more scary, he admits that he never thinks things through.
In the first episode of Lazer Tag Academy, Draxon Drear travels back in time to capture his ancestor who invented the Starlyte (which he used to travel back in time) and threatened to kill her if the authorities in the future did not surrender. The flaw in his plan should be self-evident.
Sponge Bob Square Pants: For a copepod who goes to college and makes highly elaborate plots to get the Krabby Patty formula, Plankton can be a little slow when it comes to thinking ahead of his goals. For example, a robot made to look like a customer enters the Krusty Krab. Eugene Krabs, smelling an obvious trap, takes the place of the register. To his astonishment, the robot just asks for coral bits and even pays him money after it's given its order. Suddenly, Plankton, who somehow managed to hide inside the dollar bill (even for someone his size, there must have been some hammerspace in there), pops out and gloatingly orders Krabs to hand him the secret formula. Krab's response: "Or what?" Plankton: "I don't know. I never thought I'd get this far." Krabs: "Well then, allow me to suggest your next move" (flushes him down the toilet).
The Fairly OddParents: In "Timmy's Secret Wish!", Foop, having become a lawyer, exposes the secret wish Timmy made to freeze the world in Comic Book Time so he would be able to keep Cosmo and Wanda forever, as part of his latest plan to get rid of Poof, as, since Poof only exists because of a wish Timmy made, he would be undone like all of Timmy's other wishes. Foop succeeds, but it's only afterwards that he remembers that, as Poof's Evil Counterpart, he would be undone as well.
Zuko: I thought you thought this through. Sokka: I thought you told me it's okay not to think everything through! Zuko: Maybe not everything, but this is kind of important.
In The Legend of Korra, this is a notable character trait of Korra's for most of the first season's run. And Amon takes advantage of this at every turn.
In the third season new airbenders start to appear, and naturally Korra and Tenzin want to collect them to rebuild the Air Nation. Their approach is to go to these airbenders and ask them to become air nomads. Somehow, the offer of leaving their homes and families to live a monastic, vegetarian life of meditation on a mountain does not get many takers. Or any.
The Bugs Bunny cartoon Jack Wabbit And The Beanstalk has Bugs challenging the giant to a duel. "Take twenty paces, toin, and fire. Got that, shorty?" As the giant takes his paces, he disappears into the horizon and Bugs thinks he's outsmarted the giant. But then the giant reappears over the other horizon—the twenty paces were enough to circumnavigate all the way back.
Jake: Nah... That could never happen. Finn: You didn't think this through enough. IT COULD HAPPEN!
Turned into a Running Gag with Mojo Jojo in The Powerpuff Girls. To the point where when a spree of robberies occurred in Townsville, the girls quickly ruled him out as a suspect because it was too well thought out.
Wacky Races - Every single time Dick Dastardly Stops to Cheat. It's never enough that he is ALWAYS miles ahead of every other racer, he not only has to stop to lay a trap, but also stays behind to see the payoff, which ALWAYS puts him in last place. The most absurd example was the episode where he got stuck in the mud, and pulled out by a farmer with a donkey. He decides to buy the donkey, thinking that the farmer will no longer be able to pull the other racers out. Never mind that 1) almost half the racers have some gimmick that allows them to get out on their own, including a dragon that can dry it up completely, 2) the farmer OBVIOUSLY has several beasts of burden besides the one he sold and 3) Just what the heck will he do with a frickin' donkey?!
4) after Dastardly's first opponent (Penelope) crossed the mud (with help from the farmer), he actually waited until all others passed before trying to resume his racing.
In answer to 3, he rode the donkey to the finish line because the donkey destroyed the Mean Machine.
In The Avengers: Earth's Mightiest Heroes Absorbing Man occasionally absorbs things he really shouldn't. When fighting the Hulk as metal, he absorbs rock. The Hulk promptly breaks his arms off. The metal form might not have let him win, but was at least keeping him in one piece. Much later he absorbs Mjolnir, and Thor reveals that he can now control Absorbing Man just like he does Mjolnir, and starts hitting people with him.
In an episode of Rugrats the babies imagine shrinking down and traveling into Chuckie's stomach to take out a watermelon seed he accidentally swallowed. Angelica however reveals her intention to actually water the seed so it grows and causes Chuckie to explode. She succeeds and gloats evilly, until Tommy points out it's going to explode with her inside it.
In Aqua Teen Hunger Force, after mangling his neighbor's body and several false starts, Frylock rebuilds Carl by giving him a military suit and arming him with weapons of mass destruction.
Frylock: I give you the ultimate in military hardware complete with laser cannon, indestructible titanium exoskeleton and motion-activated plasma pulse rifles. Shake: And you're gonna plug him in!? Frylock: You're right. Damn, what the hell was I thinking?
In an AnimaniacsPinky and the Brain short Brain devises a plan to infiltrate Fort Knox and make off with all of its gold. The duo actually succeed in getting into the vault, but Brain forgot about them having to carry the gold, and since they're mice you can see where this is going.
In one episode of DuckTales, the Beagle Boys manage to get inside the Money Bin and trap Scrooge outside. When they call Glomgold to gloat, Glomgold points out that they have no way to transport the money ("What are you gonna do? Carry it in your wallets!?") and that Scrooge will have an army ready to take his Bin back.
In the South Park episode "Summer Sucks", after fireworks are banned, the Mayor attempts to glorify the use of ash snakes with a giant sized one for the Fourth Of July. It works and creates an enormous display of ash... and keeps going... and going. The now somewhat nervous Mayor asks the creator when it will stop, he explains that he has no idea since he never made one this big, leading him to quote this trope to the exasperated Mayor.
In Dexter's Laboratory, this was very often one of Dexter's fatal flaws despite being a genius. Justified seeing that he was only about eight years old, and so he was bound to make mistakes.
In Sym-Bionic Titan, In order to contain a mutated and violent Ilana, Octus traps her inside the barrier that is his body. However, he failed to consider that it would allow her to attack his "head", and pretty much names the trope.
Phineas and Ferb: Doof tried to drill a tunnel to China and forgot about the lava from the center of the Earth. Doof falls into this a lot.
In the Second Dimension movie, Doof mentioned that he once tried to use an army of robots to conquer Danville, and put the self-destruct buttons on their feet so no one could reach them. You can guess what happened when they started walking...
In the Transformers Animated episode "Sari, No One's Home", Sari gets trapped alone in the Autobot base with Mixmaster and Scrapper. Unable to contact the Autobot team (her cellphone was broken), she decks herself out with a helmet, roller blades and a hockey stick to drive them out herself. As soon as the eight year-old human attacks the two story robot, her hockey stick breaks.
Sari: Okay. That's as far as my plan got.
Randy Cunningham: 9th Grade Ninja: In The McHuggers Games, the Ninja stole a McHugger from Hannibal McFist before the product was available in stores. Knowing the Ninja, like every other highschooler in Norrisville, would be attracted to the publicity event created to advertise the McHuggers, Viceroy sent a robot to the event and programmed it to attack whoever was wearing McHuggers, thinking the Ninja would be the only one. He forgot that, given the publicity campaign's goal, the spokesman would be wearing one as well.
In another episode, McFist made Viceroy make a giant robot that was just like an armadillo after watching a documentary. Armadillos have very poor eyesight, so until Randy showed up to destroy it, it was mostly flailing around blindly.
McFist fall into this a lot. Randy and Howard can be a bit impulsive as well.
In an episode of Xiaolin Showdown, Omi wishes to use the Sands of Time to return to the past. Only, his older self took it when he returned to the future. So Omi uses an alternative, tried-and-true method that lets him effectively travel forward in time (freezing himself for a few decades) so that he may retrieve the Sands of Time from his older self. You may have spotted the flaw in this plan already: with Omi frozen, there was no Omi left to grow old.
Celestia's plan in the My Little Pony: Friendship Is Magic Season 4 finale fails at every step. Send Discord to capture Tirek? They become allies. Transfer all the alicorn magic to Twilight? She trades it for hostages. Prevent Tirek from knowing about Twilight? He just has to look at the stained glass window. Tell Twilight not to let her friends in on the plan for their own protection? They immediately suspect that something's wrong, and get captured by Discord soon afterward. The only way Twilight was able to win was by unlocking the Harmony Box, and it was Discord, not Celestia, who told her how to open it.
Most people make this mistake in everyday situations when they know the results of a missed variable can be ignored or worked around (e.g. if you reach for a tool that you forgot to prepare, just get up and retrieve it). Bad things tend to happen only when too many of such mistakes line up and cause a chain reaction.
A rather better military example would be Project Pluto, the supersonic low-altitude nuclear-powered nuclear ramjet missile developed by the U.S. military (the fact that they seriously considered building that thing counts already). Project Pluto's real problem was that it was overtaken by ICBMs during its development. Aside from the difficulty in test firing it (which wasn't as crippling as it sounds, it might be an environmental disaster on wings, but this is during an age predating the green movement, meaning that a bit of isolated water in the Pacific would do), the project had a serious chance to turn out as a practical Nuke 'em to hell option. Its just that ICBMs are more practical, being faster, cheaper and harder to intercept; they may not irradiate such vast swaths of enemy land by merely flying over them, but once the major cities are gone, that hardly matters anyway.
Australia's problem with the Cane toad. Because of Cane beetles destroying sugar cane crops, a bunch of Cane toads were imported to get rid of them. Only problem was that the toads couldn't even jump that high, so they ended up being unable to eat the beetles that were on the tall stalks... which caused them to eat everything else. And then they started infesting and taking over... combined with how they're highly poisonous and can poison any animal that eats them. Yeah, that solution was not exactly the best thought out.
It doesn't help that cane beetles and cane toads aren't active at the same time of day, so they don't ever even interact.
Pause to think about that for a second. They found an animal too poisonous for Australia, home to the most venomous spider known (the Australian funnel-web spider), and even the duck-billed platypus has a venomous spike in its webbed feet.
Another Australian one: The Murray River was destroyed in an attempt to bring over European farming techniques without realising that Australian soil was ill-suited to the endeavour. Clearing of trees for land led to salt buildup, which poisoned the water and ended up clogging the river.
And yet another: Despite already knowing that Australia is the driest continent in the world (seriously, check out the sheer amount of desert there is), no government there had a sufficient water-saving plan aside from the restrictions. This came back to bite them in the arse when the country was engulfed in an extreme drought, the likes of which had not been seen for the past several centuries. Of course, now they have the exact opposite problem...
The Lake Peigneur disaster was caused by someone drilling for oil through a lake into a salt mine. Admittedly, they knew not to drill through the salt mine and just messed up when they were figuring out where to drill, but still.
During WW2, the Russians strapped explosives to dogs trained to run at tanks. Once the tank ran over the dog, the pressure-activated explosives would total the tank. The only problem? They trained the dogs using Russian tanks made to look like German ones. But Russian tanks used diesel engines; German tank engines used petrol. When in doubt, they went with what smelled familiar. Hoist by their own petard indeed.
Actually, the above example is apocryphal - the Russians barely used the whole "dogs with explosives" thing and rejected it as impractical. The Russians used old, petrol-engined tanks for the dog experiments since they had just introduced the new V-2 diesel engines on their T-34 and KV-1 tanks (older tanks like the T-26 and BT series used gasoline). Not so much "hoist by their own petard", but "hoist by war myths".
Considering Rule 34, it would have been smarter to just skip the demonstration altogether.
Quaker Oats buying Snapple for $1.7 billion. Unlike every other drink in Quaker's line-up (including, for instance, Gatorade), Snapple has to be refrigerated. It was only after the deal had gone through that Quaker realized that it had a shipping fleet of exactly zero refrigerated vehicles. Refrigerated distribution outlets soon realized this as well, and colluded on a high price to deliver the Snapple. Eventually, Quaker sold it for $300 million to another company, long after Snapple's trendiness had faded.
Nazi Germany had a problem: with the US being officially neutral but unofficially supporting the Allied war effort, German u-boats could not be used to their full effectiveness in the Atlantic. Japan attacks the United States and war breaks out, and Hitler thinks this solves his problem as he can declare war on the US because Japan is an ally, and thus finally give his naval forces the freedom they need to effectively cut off Great Britain. Of course, this also means the single largest economic and manufacturing power on the planet now doesn't have to pretend to play nice either.
Yet another WWII example is the study the Japanese commissioned on US industrial production in 1940, presumably hoping to avert this trope. The discovered, to their delight, that the so-called industrial giant of the USA was actually producing only slightly more than Japan. Huh, they think, maybe the Americans aren't an industrial powerhouse after all...unfortunately, what they failed to realize was that Japan had been at war for 3 years and was operating at unsustainably high levels, whilst the USA was at peace and barely pulling out of the Great Depression, and therefore operating at a very small fraction of its full potential. Wah-wah.
This was pretty much Benito Mussolini's war career. He is even sometime blamed for Hitler losing the war.
One particular example is how it related to the German invasion of Russia. The supply trains for that were geared for the summer months, expecting the invasion to end in a German victory before the brutal Russian winter hit - but then the invasion itself was pushed back to late June, due to Germany wasting time helping Italy out with their March 1941 invasion of Yugoslavia and Greece. As such, the Germans were still fighting in Russia when that brutal winter hit, and they had no winter clothing for their infantry or winterizing gear for their tanks.
Before the winter, there was the autumn, where Germans followed the trope perfectly by neglecting to produce tech capable of moving through Russian mud. Before that, there were the infamous Russian roads. The result was Franz Halder first writing in his diary that some vehicles break apart without enemy action, while others can't keep up with the infantry, and later writing that the situation can only improve once it gets cold enough for the roads to freeze over. That's right, he believed winter will be the solution to the problems caused by this trope.
Criminals. This tends to happen to them a lot. In example:
A few would-be ATM thieves in South Africa decide to use explosives to open up an ATM. Once the bomb goes off, the money would be theirs for the taking! But, somewhere in thinking how awesome it would be to blow up an ATM with a bomb, they forgot to make an important consideration. Namely; paper money tends to burn. Hilarity Ensues.
There have been several cases of people walking into a business, filling out a job application with their real name, address, etc., and then holding the place up at gunpoint. Of course, it doesn't take too long for the police to find them.
One example was a bank robber who decided to rob a bank, that was across from the FBI headquarters, on pay day. Oops.
Another robber went up to a bank with a stick-up note... written on the bottom of his pay slip, which had his name, address, postal code, and telephone number on it. Of course, he doesn't compare to the robber who held up the bank coming right from his work at a construction site... still wearing his hard hat, which had his name on it. Neither of them are quite as stupid as the criminals who decided to draw masks on their faces with black marker.
Another robber had the absolutely brilliant idea to rob a gun shop. He found out the hard way that the guns are not for display purposes only. Not only did he rob a gun shop, but he walked past a marked police cruiser to get there. They say he was so surprised at seeing a cop that he opened fire. Six customers and the cop drew and 4 of them returned fire. He did not survive.
Then there was the time a robber tried to rob a shop, whilst wearing a crash helmet. A crash helmet that had his name emblazoned across the front.
One bank robber decided to rob the place from the drive-thru tube system. He decided it was best to put a stick-up note and the gun in the pneumatic tube and send it to the teller.
Official policy of communist states to deal with disaster? Issue a nationwide bulletin that absolutely nothing has happenedand everything is fine, and censor any attempt to bring it to the public's attention. Well the public still becomes aware of it, but by that time, it's too late to do anything about it.
Mikhail Gorbachev, the last leader of the Soviet Union, can be credited with the peaceful dissolution of one of the worst regimes in human history, thanks to his efforts to save it.
Phase one was uskorenie, "speeding up," an attempt to clear out the old party leadership (by firing them through corruption charges) in order to bring in some new blood. However, the replacements were a little younger but still belonged to the fossilized one-party system, and now they were concerned that Gorbachev might go after them next.
Following this came glasnost, "openness," the elimination of censorship in the Soviet Union. This attempt at reform allowed the Soviet people to fully recognize just how broken their system was, that following communism left them unable to feed themselves. It opened a floodgate of anti-communist sentiment, rising nationalism from non-Russian soviets who wanted their own nation-states, and increasing criticism of Gorbachev's reforms.
To try and cut back on military spending, Gorbachev cut support to Third World client states, and more importantly ended the Brezhnev Doctrine, through which the USSR would invade any Warsaw Pact "ally" who dared attempt to modify communism in any way. Without the threat of Soviet military intervention propping them up, Eastern Europe's communist regimes collapsed almost immediately.
Attempts at privatization and economic reform were confused and haphazard thanks to a legal vacuum for legitimate businesses, so that politicians and The Mafiya benefited the most. This resulted in yet more turmoil and discontent, and set up the rise of the oligarchs that dominate The New Russia's economy.
The kicker was an effort to democratize, maybe introduce a federal system to the USSR. Unfortunately building up the state in a one-party system ended up eroding Gorbachev's power base even further and empowering rivals like Boris Yeltsin, and nationalist and non-communist parties made startling headway at the polls. The state of Russia tried to secede from the Soviet Union, Gorbachev tried to backpedal but it was far too late, the KGB tried a coup but didn't have the nerve to see it through, and thus the Cold War ended shockingly quickly, shockingly peacefully, and more or less by accident.
The Mongol Invasion of Japan. Kublai Khan was in such a rush that he ordered the Chinese boat builders to make a huge fleet (a fleet second only to the invasion fleet that launched the Invasion of Normandy) within a single year. The Chinese laborers had to supplement the sea-worthy boats with river boats that had no keel, and thus were unworthy for sea travel. Bad enough when you are crossing an ocean, even worse when that ocean is prone to violent storms and typhoons. The now-famous kamikaze led to the single greatest loss of life in a disaster at sea in recorded history, with many of the over 3,000 ships sinking with most of their crew.
Italian general Pietro Badoglio in World War I expected the Austrians to possibly break through in the Caporetto sector, and had prepared an ambush with tons of artillery to annihilate the Austrian troops, then gave the artillery commander orders to not open fire unless he ordered him to, and returned to his headquarters to wait for the enemy offensive. When the Austrians did break through at Caporetto, he gave the order... only to discover that the Austrian preparatory shelling had interrupted the phone lines, the noises of the battle covered his sound-based signals, and the heliograph's signals were blocked by the fog. The Austrians realized there was a trap only when they saw the guns and the artillery commander surrendered to them. Since then, in Italian, 'Caporetto' is synonymous with 'utter and complete defeat'.
The 1939 IRA Christmas Raid on the Phoenix Park Magazine in Dublin. After subsisting on a crate of ammunition here and a crate of ammunition there for years the IRA decided to end its ammunition problems once-and-for-all by robbing the Irish Army. Which went surprisingly well for them, netting thirteen truckloads of ammunition with no shots fired. What they had neglected to consider was exactly how they were supposed to hide thirteen truckloads of ammunition. Most of the ammunition was recovered within four days leading to a slew of arrests.
In the late 1990s, Disneyland was developing a new ride called the Rocket Rods, a high-speed thrill ride that would take riders beyond speed of most roller coasters. Sounds cool, right? Well, they were going to use the track that was originally for the People Mover, a slow, leisurely trip around Tomorrowland. The decision was made to use the track as is and build the new ride on it. As a result, since there were no banked turns, the ride vehicles would get up to speed, and then have to slow down to make the curves, and there were a lot of them. In addition, the track itself was not built to handle high speeds and began to deteriorate. Between this and the ride's very buggy control program, it was spending just as much time shut down as active, and was closed down in 2000, after only two years of operation. The thing is, it might have been successful if Disney officials had taken the more costly route of tearing the track down and building the one they really needed, with banked turns and able to handle the stresses it would be put under. As it is, the Rocket Rods stands as a monument to the poor planning and management that plagued Disneyland around the Millennium.
The infamous ARMM of Usenet. Unleashed on March 30, 1993, ARMM was a bot that attempted to automatically flag automatically generated messages for deletion. Notice the lack of the word "other" in there. That's right, ARMM triggered on itself, producing a recursive explosion of nested cancel messages that clogged lines and servers alike, with a confirmed kill of at least one poor mailserver that couldn't handle the traffic. As this was the Nineties, the gigantic recursive messages actually cost users extra money thanks to per-line charges on their Internet!
