You're being chased. Quickly, you run inside a building and close the door. But how do you keep the door closed with such a wimpy lock? Haphazardly nail random boards across the doorway!

This is a common trope in animation. Because of {{Hammerspace}}, the character can get the needed hammer in an instant, plus a pile of boards and nails. The boards will always crisscross and overlap, as if the character doesn't have time to be precise with their work due to the dire nature of the threat on the other side. Often the boards are placed in ways that would make them bulge out and very hard to nail down. In RealLife, this is a semi-realistic trope - boarding up a door is a fairly good way to barricade it, and if you have some people to hold the door closed as you do it, then it can make a reasonably speedy improvised weapon. Variations have been used in several mediaeval and early modern sieges.

The character has to watch out for who is assisting him with the barricade, though. [[TheCatCameBack Sometimes it's his pursuer]], which would in these cases overlap with AbsurdlyIneffectiveBarricade.

!!Examples

[[folder:Anime and Manga]]
* In anticipation of a typhoon, the Moroboshi family in ''Manga/UruseiYatsura'' board up all of the doors and windows this way. In Japan, storm shutters generally come standard on houses, making this RuleOfFunny.
* The anime of ''RanmaOneHalf'' has a similar episode. There's one sequence where Ranma accidentally ends up barricading himself into a hallway and several other characters in awkward positions (Akane and Nabiki in their rooms, Soun Tendo outside, Genma out of the toilet when he really needs to go).
** This also happens in one arc of the manga where [[RelationshipSabotage Ranma and most of the Tendos are trying to prevent Hinako from proposing to Soun]]. After Hinako goes outside to gain energy from two fighting dogs, Ranma and Akane hurriedly nail wood to the door and leave a note telling her to stop trying to become Soun's wife. They finish, just before Hinako blasts right through it with a chi attack.
** In another chapter, Akane gets fed up with [[DirtyOldMan Happosai]] and [[JerkWithAHeartOfGold Ranma]], so she kicks them both out of her room and boards up the door. However, it turns out that Happosai managed to not get kicked out and is looking at her lecherously. She screams Ranma's name and Ranma easily breaks through the door in his haste to get to her.
* ''Manga/SayonaraZetsubouSensei'' inverts this trope when Kafuka and Itoshiki-sensei, at Kafuka's suggestion, build a berserk board barricade...to keep a [[{{Hikikomori}} harmless]] [[InsistentTerminology "zashiki]] [[BrickJoke warashi"]] locked insider her home. ItMakesSenseInContext.

[[folder:Films]]
* In ''Film/TheMask'', the eponymous hero races out of the park, closes the doors, boards them shut, chains them shut, and for good measure, locks the door. The rest of the police force was right behind him the entire time.
* Non-comedic example: In ''NightOfTheLivingDead'', Ben uses these to board up the doors and windows of the farmhouse.
** In Creator/TomSavini's 1990 remake, they try to use interior doors to board up the windows only to learn that they're all cheap hollow-core luan doors that couldn't stop a kitten.
* Subverted in ''ScaryMovie 3'': A character boards up the front door to his house, but another character is able to open said door normally regardless.
** Mainly because he put the boards across the door, and never actually nailed them to the doorframe.
* German soldiers are seen doing this in ''The Bunker''.

[[folder:Literature]]
* Vernon Dursley does this in the beginning of ''Literature/HarryPotterAndThePhilosophersStone'' in an attempt to stop Harry's letters from getting into the house. [[RuleOfFunny It doesn't work, of course.]]

[[folder:Live-Action TV]]
* In ''Series/TheGoodies'', in the episode Bunfight in the O.K. Tearooms a random resident is seen boarding up his house from the outside. HilarityEnsues as he jumps into a nearby barrel instead.
* Invoked in the ''[[BlackAdder Blackadder Goes Forth]]'' episode "General Hospital".
-->'''General Melchett:''' Great Scott! Even ''you'' know [the secret British plan]! Ah! Ah! Bolt all the doors! Hammer large pieces of crooked wood against the windows! This security leak is far worse than we imagined!

[[folder:Video Games]]
* In ''VideoGame/UrbanDead'', characters can build barricades out of literally anything. In about one sixth of the amount of time it takes to stand up.
* In ''VideoGame/{{Minecraft}}'', while not always using boards, one can build a wall very quickly to keep a monster away.
* For that matter the same goes for it's 2d counterpart ''VideoGame/{{Terraria}}''. Especially useful during the much-dreaded Blood Moons.
* This is how they try and keep the zombies out in NaziZombies (Call of Duty World at War/Black Ops). Indeed, its such a fundamental part of the game mechanics you get points (to buy weapons) from nailing boards down and a power up called Carpenter auto repairs all windows in the level in this style at once.

[[folder:Western Animation]]
* Done in a few ''WesternAnimation/TinyToonAdventures'' episodes.
* Common gag in ''WesternAnimation/LooneyTunes'' cartoons, desperate characters may even resort to producing bricks and mortar from {{Hammerspace}} and adding a brick wall to the fortifications
* ''CampLazlo'', where the Bean Scouts barricade the door of their cabin to keep the Squirrel Scouts out. In order to get the wood for the barricade, they completely dismantle the back wall of their cabin.
* In a segment from ''WesternAnimation/TheSimpsons''' "Treehouse of Horror III" episode spoofing the aforementioned ''Night of the Living Dead'', the family board up the windows in this manner, but when Marge asks Homer if he's boarded up the front door, he absent-mindedly mentions that he hasn't.
* Wakko Warner takes this trope a step further in the ''WesternAnimation/{{Animaniacs}}'' episode "Temporary Insanity". In a bid to beat his siblings to the phone (Just roll with it) he first shuts the door, pulls a steel gate in front of it, then a steel door, and then an elevator door! As a finishing touch, he adds a wall of bricks.
* Happens several times in ''WesternAnimation/TomAndJerry''.
* In the ''WesternAnimation/SouthPark'' episode "Butt Out" Cartman wants to star in Rob Reiner's anti-smoking commercial yet the other boys don't want anything to do with him at this point. When Kyle tells him this, Cartman thinks Kyle is trying to trick him because he wants the part himself. That night Cartman boards up Kyle's door so he can't get out. Kyle, who is already outside, reiterates what he said before and it seems for a second that Cartman is considering not to show up. He then continues with his hammering.
* When a priest on ''RobotChicken'' sees a family playing "[[FictionalVideogame Humping Robot]]" he boards up the door and pours gasoline on the ground. [[KillItWithFire Before he throws a match inside]], he changes his mind and decides to join them.
* In an episode of ''{{Catscratch}}'', when Waffle mentions he's friends with Squeakers the mouse, Gordon and Mr. Blik board up the door. But when Waffle mention's he's actually ''inside'' the house, they unboard the door, go outside, and board up the house with ''a tree.''
* In the ''SpongeBobSquarePants'' episode "I Was a Teenage Gary", Squidward barricades his front door and window to keep a transformed [=SpongeBob=] from getting in. The [=SpongeSnail=] manages to get inside by slipping through a knothole in the wood.
** In "Squid's Day Off", Squidward boards up his door with wood, chains and police tape to keep himself inside and enjoy his "day off" without running back to the Krusty Krab to check up on [=SpongeBob=].
