History ShoutOut / AdventureTime

** It also possibly pays homage to ''Literature/TheRoad'' as well as some zombie movies such as ''Film/28DaysLater''

* The Nightsword that Peppermint Butler gives Finn in "Marcie and Hundson" has a built-in compass, like the Red Ryder BB gun in ''Film/AChristmasStory''.

** It also makes a few SuperMarioBrothers references, like level-1, and the Bomba (Bob-omb).

** Also from "Mortal Recoil", the view through the Ice King's "wizard eyes" could be a reference to Creator/HPLovecraft's short story "From Beyond".

* Ash erasing Marceline's memory of her breaking up with him was slightly inspired by EternalSunshineOfTheSpotlessMind.

* "Mortal Recoil" contains a bunch of clear references to ''Film/TheExorcist'' and ''TheGrudge''.

** On the opposite end of the spectrum, Finn's casts breaking is really similar to ForrestGump's leg braces.

Finn has an Ioun Stone orbiting his head

** The animated book is reminiscent of MickeyMouse.
** [[MisterRogersNeighborhood "Everything is true in the garden of your mind."]]

* "Little Brother": Kent's archetypical HerosJourney with HighFantasy elements through a tight, dark, brown, tubular space is reminiscent to ''WesternAnimation/SouthPark''[='s=] Lemmiwinks adventures.
** The Rat King bears more than a passing resemblance to [[Anime/{{Godmars}} Emperor Zuul]] of all things. (They even fight in an area that resembles the background of their final fight in SuperRobotWarsZ.)

** In the same episode, the Bath Boy Gang Leader hold an [[CaptainErsatz uncanny resemblance]] in mannerisms, body shape, and voice to King Herod from JesusChristSuperstar.

* "Up A Tree" has the occupants of the tree doing an IAmLegion chant that sounds very familiar: [[Franchise/PiratesOfTheCaribbean In the tree, part of the tree. In the tree, part of the tree.]]

* "James Baxter the Horse" is a homage to a {{Creator/Disney}} and {{Dreamworks}} animator of the same name. Finn looks up to the fictional James Baxter like how Creator/PendletonWard looks up to the real James Baxter - who animated and voiced his namesake.

* Clarence and Ghost Princess' story is basically that of [[TheIliad Achilles]] [[Myth/ClassicalMythology and Penthesilea.]]

* The episode "Goliad" and its eponymous character are named after Goliad, Texas. While [[RememberTheAlamo the place figures in Texas history]], there's no intended deeper meaning in the show; [[http://www.formspring.me/jessemoynihan/q/334526374276526286 the episode's writer just thought]] "Goliad" [[AwesomeMcCoolname sounded cool]].

* The origin of the Gumball Guard in "Rattleballs" is a shout out to the Manhunters from the ''Comicbook/GreenLantern'' mythos. They even have the same color scheme as the Manhunters.

** Also from "Mortal Recoil", the view through the Ice King's "wizard eyes" could be a reference to HPLovecraft's short story "From Beyond".

** The entire memory sequence is a reference to ''BeingJohnMalkovich'', what with the shifting gravity, various doors through memories, and the nature of being inside someone's head.
** It can also be seen as a refrence to {{Inception}} with the extraction of an idea from a dream.

** It might be a coincidence, but the title of the episode is similar the [[Music/NWA]] song [[Music/StraightOuttaCompton "A Bitch Iz A Bitch"]].

*** That episode is also as close as you can get to a {{Superjail}} episode.
