ASitcom plot where the characters are trying to pull off some kind of easy, straightforward operation; throw a surprise party, open a restaurant, or pick someone up at the airport. Either a series of things go wrong, they screw up through their own natural laziness, cheapness, or stubbornness; or one solitary thing goes awry and the whole simple plan falls to pieces.
Once things have disintegrated, the characters go to ludicrous extremes to fix them, and aFawlty Towers Plot orIndy Ploy evolves.
Contrast withZany Scheme. When the end goal goes through despite this trope, you haveDespite the Plan. When the character expected circumstances to arise and improvised about them, he's playingXanatos Speed Chess.Plethora of Mistakes is this trope applied to crime thriller fiction, and involves everything going wrong for the sake of going wrong in order to teach theAesop that crime doesn't pay. A plan revealed to the audience tends to fail miserably due to theUnspoken Plan Guarantee.
In more serious stories, anything described before the fact as an "in-and-out" operation is almost certain to fall into this trope.
Not to be confused with the film of the same name (which, itself, wasn't very simple). Also not to be confused with the band of the same name. Which is more complicated than a beginner violinist, but simpler than Beethoven.
However, this simple plan turns out to have plenty of unintendedgains, namely the contents of a giant's castle.
Film
TheCoen Brothers have almost made this a trademark of their films, be they comedy or drama.The Lady Killers,Intolerable Cruelty,The Big Lebowski,The Hudsucker Proxy,The Man Who Wasn't There andBlood Simple all play on this trope to a substantial degree.Fargo is probably their best example: Hire two crooks to kidnap your wife, and get your cheapskate Father-in-law to pay the ransom.What Could Possibly Go Wrong??
Which is actually not far off from the plot ofSuicide Kings.
Played straight and very brutally in the movieA Simple Plan: what starts as a plan to split up a huge sack of money found in the woods ends up leaving a trail of bodiesincluding two of the three guys who found the money, and at the end of it all,the money is marked anyway, and has to be burnt.
The poster for the 70's classicDog Day Afternoon even describes the trope as its plot: "The robbery should have taken ten minutes. 4 hours later the bank was like a circus sideshow. 8 hours later, it was the hottest thing on live TV. 12 hours later, it was history."
Neatly done inQuick Change; the complex, intricate bank robbery that the protagonist and his friends have planned goes off without a hitch. However, whatshould be the incredibly simple matter of driving to the airport to make the getaway turns into a convoluted, mishap-ridden nightmare.
Planes, Trains and Automobiles is about a guy who just wants to back home for Thanksgiving. A whole fiasco erupts from this.
Adventures in Babysitting: Heroine is babysitting when her friend calls and asks for a ride out of the city. Heroine takes kids with so that she can still keep an eye on them. Then plot happens.
Bullet Train: Board train. Steal a briefcase. Get off train at next stop. That was all Ladybug was supposed to have needed to do. Of course, things didn't work out that way.
Literature
inThe Adventures of Huckleberry Finn, breaking Jim back out of slavery would be an almost effortless operation for Huck and Tom Sawyer, but Tom insists on doing outlandish things like sneaking tools in through Jim's lunch, trying to dig an entrance hole into the (unguarded and unlocked) slave quarters with pocket knives, and trying to scare the Phelpses into staying inside so they can kidnap Jim without fear of getting caught. All on top of the long process of forcing Jim to keep a prison diary.
Donald E. Westlake likes to use this trope.The Hot Rock and, of course,What's the Worst That Could Happen? are two examples.The Worst is interestingly the one Dortmunder book in which the plan wentperfectly.
Getting the Hrum gold in theFarsala Trilogy. It starts as a plan so simple it could probably be described in less than a sentence and evolves into about a third ofForging The Sword.
This is whatFrasier generally does when it's not doingThree Is Company. Lampshaded at one point when Martin scoffs at yetanother Simple Plan that Niles and Frasier have devised (sharing an office as psychiatrists):
Martin: The book you two tried to write together;that was a bad idea. The restaurant you opened together;that was a bad idea. Butthis... no, that restaurant was still the dumbest.
As indicated above, it also happened frequently inFawlty Towers.
Frequently occurs, and isLampshaded, inFarscape. As Aeryn puts it to John "Your plans never work! Not the way you detail them!" Eventually he admits this when anunspoken plan actually works as planned, "Yeah, it's a first, isn't it?"
There is even an episode subtitled "A Not So Simple Plan".
Played painfully straight on theMy So-Called Life episode "Life of Brian" where the simple plan is to go to the school dance. One kid changes dates, which sets off a chain reaction of people changing theirs, until nobody is happy with what results. Despite sounding comedic, the episode showed what it would be like to actually have to deal with that in real life.
The collapse of "simple plans" was a common plot point inFirefly, although usually due more to bad luck than anything else. This led Mal to gripe in the episode "Safe," upon finding himself in yet another shootout, "Why don't it ever go smooth?"
He suffers this to the point where it's made into a character trait ("Things Don't Go Smooth") in theSerenity RPG. Mal has the severe version of this trait. Player-made characters can take this drawback as well, giving theGame Master an excuse to ensure thatHilarity Ensues no matter how well the players plan their various hijinks.
Many an episode ofDrake and Josh uses this trope, memorably one where their attempt to deliver a cake to their elderly aunt's wedding leaves them stranded in the middle of nowhere and blowing up the car they borrowed.
A somewhat common theme inLeverage. Of course there's a reason it takes five of the world's best thieves to pull these cons off. Even the simplest plans have potential to go all to hell for reasons as simple and unpredictable as a mook of the bad guy calling his cousin or as large as someone trying to crash land the plane they're on to run a con.
Lampshaded to a degree inThe Mentalist, a drama. Patrick Jane refers to one of his schemes as being a "simple plan" and Lisbon says that she likes it simple. It's when he starts getting out the costumes and such that she gets worried.
On oneFriends episode, the plan is to throw Rachel a birthday party. Things start getting messy when the parents refuse to be in the same room and two parties get planned and then...
Happens all the time inStargate SG-1, nicelyLampshaded in the episode "Off the Grid" after a plan has gone pretty badly wrong:
Jackson: Uhh…I have a question: Why would we make the Gate magically disappear BEFORE we had a chance to escape through it? Worrel: Bad timing? Jackson: Th-that's got to be the single stupidest thing I've ever heard. Worrel: Do things always go according to plan in your world Dr Jackson? Jackson: [beat] No. Not usually, no.
When not forming theirzany schemes, the study group inCommunity has come up with some great ones:
Jeff: "So, what, to even the score I have to drunk dial her? Isn't that absurdly simplistic? Would it even work?"
Virtually every episode ofIt's Always Sunny in Philadelphia revolves around the gang hatching some sort of plan. Usually involving monetary gain or revenge.
Doctor Who. Anytime the TARDIS lands and the crew has something relaxing or normal planned—going to the beach, visiting their family, maybe just picking up some milk—will end up with them all running for their lives.Every. Single. Time.
In "The Doctor's Wife", the TARDIS, temporarily put in a human body, says that she doesn't bring the Doctor to where he wants to go, but where heneeds to go.
TheMythBusters have often come across myths that, on the surface, seem easy enough to test...and then some factor they hadn't counted on makes it a nightmare.
Adam: You shouldnever expect Plan A to go off without a hitch! Me and Jamie, it's usually Plan D.
In Season 3 ofJustified a corrupt prison guard and his prison nurse buddy have the great idea to break Dicky Bennett out of prison, have him lead them to the $3 million his late mother hid away and then kill him. They do not count on the fact that they will have to takeDewey Crowe with them or that US Marshal Raylan Givens will suspect them right away. They also do not realize that most of the money is already gone or that the person holding the rest of the money feels honor bound to keep Dickie alive and is much deadlier than they are.
Tabletop Games
The RPGExalted has a dramatic example: as penalty for their actions in overthrowing the Primordials, the Sidereal Exalted, Heaven's bureaucrats, were cursed so that whenever they get together in large numbers to create a plan, it usually goes horribly, horribly wrong. How horribly wrong? Well, seeing as their last great get together resulted in the death of Creation's god-kings (mind you,they kind of deserved it) and could be indirectly blamed for an apocalyptic disease, an invasion byThe Fair Folk, the fall of a Golden Age of magic and technology, and untold amounts of Creation's landmass dissolving back into the Wyld, they can only go up from here.
This sort of nonsense is de rigueur inParanoia, but occasionally, you can get asubversion.
The introduction of theShadowrun Fourth Edition rulebook has an experienced runner asserting that the scariest words in the world are"It'll be easy." Then goes on to detail a supposedly easy corporate espionage and sabotage mission that, due to a double-cross bythe Johnson's Humanis-connected assistant, ended with two of the narrator's team being fatally shot, as well as the teamalmost being responsible for the mass murder of a sizable amount of the ork and troll population because of the assistant's poisoning of the stuff that was supposed to go into the rival company's drink to make it taste bad.
Christian intends to learn enough of Cyrano to stopPlaying Cyrano and woo Roxanehimself.
De Guiche plans to visit Roxane instead of going to war.
Roxane plans to deceive De Guiche so he would let the Gascon Cadets out of the war by telling him this would be the bestRevenge against Cyrano becauseWar Is Glorious.
Le Bret and Ragueneau plan to leave Roxane unaware of Cyrano’s mortal wound when they left the nunnery to attend him.
Video Games
The Playstation gameIncredible Crisis revolves around a day in the life of the Tanamatsuri family. The Simple Plan is to get home in time for grandmother Hatsu's birthday party, but the other members of the family get involved in one bizarre misadventure after another. To name just a few: Taneo, the father and a grade-ASalaryman, gets chased around by a giant globe that fell off a statue, and at one point ends up going the wrong way down a busy highway on a stretcher; Etsuko, the mother, gets kidnapped by robbers and eventually ends up piloting a jet fighter into battle against a giant rampaging teddy bear; Tsuyoshi, the son, gets shrunk by weird alien rays, and has to dodge insects while trying to make his way home safely; and Ririka, the daughter, has to protect a tiny UFO while helping it reunite with the "mother" ship.
There is of courseConker's Bad Fur Day where Conker's plan of simply going home after a night of drinking doesn't work at all.
The real-life development of the game is arguably an example as well, since the development team started out with the goal of making a generic cute-animal 3D platformer. Quite a lot of delays later, it didn't quite turn out that way.
Combined with amassive dose ofGenre Savviness inSluggy Freelance. After a relatively simple plan to steal aMad Scientist's Displacement Drive Vehicle goes awry and ends up destroying the vehicle and scientist's entire island complex, Torg learns the experience. So, when he decides to try and take down Hereti-Corphe figures the best way is to pretend thatthey have a Displacement Drive Vehicle, too, try and steal it, and cause so much unintentional pandemonium that it brings the whole company down.
The tendency for simple plans to go horrible wrong islampshaded inthisWapsi Square strip. Said simple plan results in being shot at and bringing down a group of smugglers in Cairo.
The plot ofProblem Sleuth starts because Problem Sleuth wants togo outside.
InSchlock Mercenary, Tagon's Toughs are genera savvy enough that if told something should be simple, they immediately start planning for the worst. And not even senior members of the Toughs are allowed to say "What's the worstthat could happen?"

MostStrong Bad Emails are like this. A simple e-mail asking if he's ever been on a road trip leads to him and The Cheat being stuck in the car all day, and a pretend pizza place to meet some girls results in an actual, well-reviewed pizza place.
Survival of the Fittest has an ongoing subplot about escape that is quickly going in this direction.
Anika just wanted to get some water for her parents. Then an eagle mistook her toy for lunch.
Western Animation
Somewhat subverted in theJem episode, "Broadway Magic" in which using a forged letter from "Rio", the Misfits are able to lock Jem in the crown of the Statue of Liberty. However, the Misfits are unaware that Jem's earrings are part of a illusion-creating computer. The show plays this trope straight in many episodes.
Subverted in an episode ofStorm Hawks, where the plan to infiltrate a Cyclonian prison base is (to the audience) simultaneously planned out and executed thanks toFlash Forwards, thereby invoking the spirit of anUnspoken Plan Guarantee.
Every episode ofRegular Show so far has fit this trope to an extent.
