* In ''ComicBook/ArkhamAsylumASeriousHouseOnSeriousEarth'', the scene where Batman stabs his own hand with a shard of glass had the script call for Batman to draw a small amount of blood to snap himself out of his daze. Dave [=McKean=] however, drew the scene with Batman driving the shard straight through his hand. Grant Morrison was delighted by this (since it made an already freaky scene absolutely nightmarish), and kept it in.
* ComicBook/LexLuthor was originally drawn with [[EvilRedhead red hair]], but was abruptly changed to [[BaldOfEvil bald]] after an artistic mistake by illustrator Leo Nowak. Not only has it stuck with Luthor's popular image ever since, but was indirectly responsible for Luthor taking the Ultra-Humanite's place as Supes' arch nemesis as DC didn't want two bald mad scientists battling Superman (and thus Ultra-Humanite gained his trademark tendency to BodySurf and was PutOnABus for several decades).
* During one arc of ''ComicBook/{{Invincible}}'', [[spoiler: Omni-Man]] marries an insect-like alien, and there's a panel of him kissing her and Invincible looking disgusted. According to the sketchbook in the back, the artist made this as a joke and Robert Kirkman decided to keep it in the actual issue.
* ComicBook/{{Wolverine}}'s iconic mask was due to this trope -- when he joined the ComicBook/XMen in ''Giant-Size X-Men'' #1, he was meant to keep the same mask design that he had when he first appeared in ''ComicBook/TheIncredibleHulk'' #181. However, the person who drew it, made the ears and eyes too wide. However, when it was shown, they thought that it made him look like Franchise/{{Batman}} and it was kept in.
* In the script for ''ComicBook/TheAtlantisChronicles'' an ''ComicBook/{{Aquaman}}'' spinoff, Peter David [[http://www.dcinthe80s.com/2016/03/peter-david-reveals-dcs-big-plans-for.html described]] the "face" of the meteor that destroyed Atlantis. He meant it metaphorically, but the artist, working from a script translated into Spanish, took him literally and drew the meteor with a skull face on it. When he saw the art, David said "Keep it," reasoning that the only thing more terrifying than a meteor heading right for you is a meteor heading right for you WITH A SKULL ON IT.
* Done in-universe in two Italian ComicBook/DisneyMouseAndDuckComics stories:

* Creator/GeorgePerez was designing ComicBook/{{Starfire}} when Joe Orlando passed by, looked at the sketches and suggested that Perez make her hair longer. Perez listened.

* ''ComicBook/{{Planetary}}'' #7 was supposed to have a ComicBook/JohnConstantine {{Expy}} shave his head and ditch his trenchcoat to become [[ComicBook/TheInvisibles King Mob]]. Artist John Cassaday instead drew him as [[ComicBook/{{Transmetropolitan}} Spider Jerusalem]]. Creator/WarrenEllis was amused enough to let it slide.

* In the script for an issue of ''ComicBook/{{Aquaman}}: The Atlantis Chronicles'', Peter David [[http://www.dcinthe80s.com/2016/03/peter-david-reveals-dcs-big-plans-for.html described]] the "face" of the meteor that destroyed Atlantis. He meant it metaphorically, but the artist, working from a script translated into Spanish, took him literally and drew the meteor with a skull face on it.

** InUniverse example in ''Literature/TheSilmarillion''. Aulë, one of the Valar sent to craft the world before the coming of the mortal races, created the Dwarfs in secret so he'd have students to teach but could not give them souls. The god of the setting, Eru Ilúvatar, adopted them and gave them souls himself even though they weren't originally part of his plan for the world. This caused some strife down the line, but since [[SatanicArchetype Melkor]] had already screwed things up beyond recognition and they were specifically built to resist his corruption it worked out okay. The Ents also weren't in the original plan, but were made at the request of Aulë's wife Yavanna as guardians of the wild places.

Differs slightly from attaching HilariousOuttakes to the ends of shows. Related to NoFourthWall and EnforcedMethodActing - especially in cases of pain and surprise. See also RuleOfFunny, RuleOfCool.

* The Slap Chop commercial features Creator/VinceOffer throwing a competitor product [[BlindShoulderToss over his shoulder into the sink]]. The Spanish-language version of the commercial leaves in a blooper where it ''[[https://www.youtube.com/watch?v=b86SOHZ0nIA#t=1m2s smashes the venetian blinds behind him.]]'' It was presumably kept in thanks to how 31 flavors of [[SugarWiki/FunnyMoments hilarious]] it is. This was referenced in a later commercial for the Da Vinci Pro Cutting Tool, where Vince throws a $200 food slicer out the window.

* ComicBook/{{Wolverine}}'s iconic mask was due to this trope -- when he joined the ComicBook/XMen in ''Giant-Size X-Men'' #1, he was meant to keep the same mask design that he had when he first appeared in ''ComicBook/TheIncredibleHulk'' #181.

The preservation of ad libs, improvisations, and the occasional accident or mistimed what-have-you for dramatic or comic effect, sometimes at the expense of continuity.
