!!Doom
* The infamous [[HarderThanHard Nightmare!]] difficulty wasn't in the original release of the game. People who beat it actually started complaining to Id that Ultra-Violence was ItsEasySoItSucks for the hardest difficulty, so the devs [[GoneHorriblyRight took them up on their challenge]] on patches and future re-releases with a difficulty that [[LampshadeHanging isn't even remotely fair.]]
* The DOOM Wiki's page on the Doomguy had this little Gem:
--> "The introduction of "jump" and "duck" controls in source ports such as ZDoom and Skulltag , although not canon, seem to quash the widespread [[WildMassGuessing rumours]] of the 1990s that the Doom marine was a paraplegic transporting himself by a [[CrazyAwesome rocket powered wheelchair.]]"

!!Doom 2
* From the ending of ''Doom II'':
-->The invasion is over. Earth is saved. Hell is a wreck. [[FridgeLogic You wonder]] [[LampshadeHanging where bad folks will go when they die, now.]]
* [=MAP20=] of ''Doom II'', ''Gotcha!'', becomes this in retrospect- the demons deployed their two most powerful monsters in the same spot, thinking it a foolproof plan. If Doomguy plays his cards right, they'll end up... [[EpicFail fighting each other]].
* The Xbox 360 Arcade port of ''Doom II'' has achievements that quote the Doom comic, including "You Have Huge Guts" for killing a Cyberdemon with your fists.

!!The Film
* During the first-person sequence, Reaper takes a blind corner and comes face to face with a possessed researcher who starts to gloat with an EvilLaugh. Reaper puts the muzzle of his weapon under the guy's chin and calmly blows his face off in mid-laugh before moving along.

!!The [[Comicbook/{{Doom}} tie-in comic]]
* The comicbook in its entirety. Special mentions go to:
** "[[RuleOfThree Stupid! Stupid! Stupid]] Imp! You're stupid! And you're gonna be stupid and '''dead!'''"
** "Imps? Zombies? You think you can get me?!? (''Thinks to himself'') Wait. Maybe they don't think. (''Starts yelling'') Well I do! And I think you're dead! Dead! '''Dead!''' '''DEAD!'''"
** "Rip and tear! Rip and tear your guts! You are huge! That means you have '''HUGE GUTS! RIP AND TEAR!''' Oooh, here comes the night train! Choo choo '''CHA-BOOGIE!'''"
** "[[IncomingHam Knock knock who's there? ME!]] [[MadnessMantra ME ME ME ME ME ME ME ME]]"
** "Aah! [[ChainsawGood Chainsaw! The Great Communicator!]]"
** "Now I'm RADIOACTIVE! [[CaptainObvious That can't be good!]]"

!!Game Reviews
* The [[https://web.archive.org/web/20120104155012/http://www.next-gen.biz/reviews/doom-review EDGE review]], starting with the infamous line "[[ComicallyMissingThePoint If only you could talk to the monsters...]]"
* [=GamePro's=] infamous "[[http://knowyourmeme.com/memes/protip PRO TIP]]: Shoot the Cyberdemon until it dies." [[spoiler:It's fake--the "magazine scan" is Photoshopped together--but it's funny all the same.]]

!!Game Mods
* The Rickroller. We would say "nuff said," but no; [[http://www.youtube.com/watch?v=SL0VncaV0D0 you've gotta see this one]].
* One visual glitch is that, regardless of where on the image an enemy's weapon is, its attack emerges from its midriff. This resulted in unintended humour in the "Ultimate [[Franchise/TheSimpsons Simpsons]]" Doom mod, where the Cyberdemon is Mr. Burns... and [[PhallicWeapon his rockets emerge from his crotch]].
* TheCraftyTitan's Doom Hack... better known as [[VideoGame/{{Touhou}} Yukkuri]] Doom, in which everything runs on RuleOfFunny and the Yukkuris are in no short supply. Oh and the rocket launcher is replaced with [[VideoGame/MetalSlug RAWKET LAWNCHAIR]] literally. https://www.youtube.com/watch?v=dske-7XjaiA part of the game in action.
* Russian Overkill gives the player intentionally [[GameBreaker game breakingly-powerful]] weapons, items which can casually give the player hundreds or thousands of HP in health and 100% damage reduction armor, and [[YouNukeEm allows you to launch several flavors of nuclear weapon]] into your foes. What do they get? Health multipliers if you're feeling generous. Even the notorious nuts.wad becomes a joke with the [[NoKillLikeOverkill absurdly overpowered arsenal]] you have available to you. Some highlights of your very extensive arsenal include:
** A character who can launch [[Machinima/TheGmodIdiotBox explosive, homing CRT monitors]]. Or drop [[{{VideoGame/Worms}} a certain highly-explosive donkey statue]].
** A character who can [[Film/ThreeHundred Sparta kick]] hard enough to one-shot a Cyberdemon.
** A replacement for the invulnerability sphere that makes you scream at the top of your lungs while heavy metal blares in the background.
** A ''quadruple barreled'' hunting shotgun with an alternate fire that lets your character wield '''''four''''' of them at once. The recoil sends them soaring.
** An automatic shotgun that can launch a spread of empty shell casings.
** An automatic shotgun that can launch a giant, bouncing shell casing that spews hundreds of normal sized shell casings in all directions to the tune of 1812 Overture.
** The most powerful weapon of all is a beacon which drops a Hindenburg-sized (and shaped) nuke that falls to the tune of Ride of the Valkyries before exploding with enough force to potentially wipe out entire maps. Even the above-mentioned nuts.wad, with over 10,000 monsters, will have upwards of 8,000 of them killed in one blast if used right.
*** Naturally, the player is not immune to their own ordinance and they quickly become a greater threat to themselves than the enemies ever were.
* Based on a [[http://iddqd.ru/pic/kartinki/DooD.jpg rather infamous manipulation of the cover art]], we get the performance art masterpiece that is: [[https://www.youtube.com/watch?v=LEDegd4HIn4 DooD]] Everything is mirrored down the vertical middle of itself. The monsters, your character's model, the weapons, individual map textures... even the ''map itself'' was redesigned to work after being mirrored.
* The politically-incorrect [[https://www.youtube.com/watch?v=614akDkzvtE /pol/.wad]] made by some imageboard users has a lot of blackly amusing details in its design. For example, there are 'dark' versions of the Barons of Hell that turn into buckets of fried KFC when slain, Wolfenstein 3D Nazi guards are used in one portion of the map, one of the enemies is basically Shrek, and a number of irreverent soundbites were added. By far the most absurd and surreal part? The [[http://www.youtube.com/watch?v=-XhsuJLA3ko climax of the custom level]]. Having collected all the keycards, you return to the main chamber and hit the main switch. You will be immediately bombarded with the song 'Navras' by Juno Reactor, while the walls open up to reveal image macros of Ron Paul in his memetic incarnation of Doom Paul and you get besieged by several Ron Paul-ized Icons of Sin spawning demons into the room. After a long space of time wherein you have to survive the barrage of demons, the exit will eventually be revealed.
* If you thought that /pol/.wad was controversial, we also have [[https://mega.nz/#!C8twCZyb!yfDzaYu9NafZVCl982Y-D66k-873MmIfrt0sU0HnerQ Trump]][[https://www.youtube.com/watch?v=hR8QSJ1shO8 Doom]] which features Creator/DonaldTrump as main character, but not as a VillainProtagonist, but rather, a HeroProtagonist, where you have to fight Bernie Sanders, and yes, UsefulNotes/HillaryRodhamClinton, bacause they let aliens to invade earth with their help, and now Donald have to stop them before is too late. In your way you will encounter peculiar enemies, like Bernie soldiers(which are reskins from the [[VideoGame/Wolfenstein3D SS Soldiers]]) or black imps, even the normal imps are redisigned, [[CrossesTheLineTwice AS ILLEGAL MEXICANS!]]. The CrowningMomentOfFunny can be the weapon of the trump glove which every time you fire he says "[[CatchPhrase YOU'RE FIRED]]"
** And if you choose Skeleton Warrior difficulty, [[EasyModeMockery you get a game so trivially easy,]] [[FailureIsTheOnlyOption that the game decides that you won't win no matter what.]]
