History ShoutOut / AdventureTime

* Neddy is likely based off from [[Myth/NorseMythology Nidhoggr]] the dragon that gnaw's on the roots of Yggdrasil.

* Marceline riding the Rock Giant's finger to the music shop nearly resembles the opening sequence of WesternAnimation/{{Superjail}}

** In the same episode, the Wizard Abracadaniel shouts "Cantrip!" upon casting. In D&D, a cantrip is a minor spell typically only useful as a distraction in combat (incidentally, exactly the kind of [[UselessUsefulSpell magic]] [[SpoonyBard Abracadaniel]] uses.)

* In ''Adventure Time: Hey Ice King! Why’d you steal our garbage?!!'' if you try to enter the first dungeon before finding Finn's sword, Jake tells Finn that "It's dangerous to go alone." a famous line from the original ''VideoGame/TheLegendOfZelda''.

* "James Baxter the Horse" is a homage to a {{Creator/Disney}} and Creator/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.

* Scorcher the [[ImplacableMan unstoppable]] [[PlayingWithFire fire-wielding]] [[ProfessionalKiller assassin]] from "Hitman" basically ''is'' Sabrac the, um, [[CaptainErsatz unstoppable fire-wielding assassin]] from ''LightNovel/ShakuganNoShana''.

* For some reason in "Everything's Jake", all the major extra characters of the episode are voiced by Futurama voice actors using the voices of characters from the show. For instance, Jake (voiced by John Dimaggio, voice of Bender) has a best friend with the voice of Phillip J. Fry, encounters and authority figure with the voice of Zapp Branigan, is cautioned by a scientist with The Professor's voice who leaves behind his father with Farnsworth Jr's voice.

** Speaking of anime, let's play a drinking game. Drink for every ''Anime/FullmetalAlchemist'' reference. So, let's see. Two blond brothers, the older one has a mechanical arm; the mechanical arm can become a sword; the family household bursts into flames; untold power coming from red stones [[spoiler: at the cost of thousands of lives]]; [[spoiler: the forceful creation of alternate universes in which one is based in a rural farmtown]]...

* 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]]. Goliad's and Stormo's third eyes that erupt from their foreheads when they use their psychic powers is a reference to the main antagonist's pineal gland stalk in the film ''Film/FromBeyond''.

* The episode "No One Can Hear You", references ''Film/{{Alien}}'' when [[spoiler:the candy people are shown to be stuck to the walls of the sewer with a goo, like the Xenomorphs do the their victims.]] Even the title is borrowed from the {{tagline}} of the movie: "In space, '''no one can hear you''' scream." [[EpisodeFinishesTheTitle Finn and Jake are screaming in the title card]].

* Finn playing with the mini-people in "All the Little People" is very reminiscent of ''VideoGame/TheSims'', the minis even [[SpeakingSimlish speak in gibberish]].

* Earl of Lemongrab is an allusion to Mary Shelley's novel "Frankenstein." Like Frankenstein's Monster, he is a science experiment gone wrong who is rejected by his creator and forced to live in isolation. Lemongrab is also an allusion to Lovecraft's "Herbert West: Re-Animator," in which a mad scientist brings to life corpses, which become screaming, unintelligent psychos after he injects them with chemicals.

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

ShoutOuts in ''WesternAnimation/AdventureTime''.

* [[Film/{{Dune}} The Porp must Flow]] from "Dark Purple".

* In "Too Old", the original Lemongrab's appearance as a bloated Caligula figure that moves around by floating is very reminiscent of [[Film/{{Dune}} Baron Harkonnen]].

** Also the Headless Horseman in ''Film/SleepyHollow'' (which is probably a shout-out too given how much it's influenced by Film/HammerHorror movies).

* The Lich King is a horned, ridiculously scary, skull-faced monarch who can raise skeletons and whose power lies in a pit of green ooze. Compare to [[Disney/TheBlackCauldron The Horned King]], a horned, ridiculously scary, skull-faced monarch who can raise skeletons and whose power lies in a pit of green ooze.

* The Ice King is shown in one episode to have a [[Memes/{{Music}} "Ring, Ring, Ring, Ring,]] '''[[EarWorm banana phone]]'''"

** The look and CallingYourAttacks nature of the "Vampire Kick" may be a reference to ''Franchise/KamenRider''.

** Jake's use of Corn warriors may be a reference to ''TabletopGame/{{Warhammer}}'' and the Chaos god Khorne.

* "City of Thieves":
** May be a coincidence, but ''City of Thieves'' was one of the most popular ''Literature/FightingFantasy'' gamebooks.
** The section when Finn believes himself to have been darkened by the city is a spot-on parody of ''WesternAnimation/BatmanTheAnimatedSeries''.

** The teddy bear/cassette player may be a reference to Teddy Ruxpin, an animatronic toy extremely popular during the mid-1980s.

* "The Tower" looks like it's made out of VideoGame/{{Minecraft}} blocks.

** The song that Jake and Finn sing when they're first transformed is "The Queen of Night" from Mozart's "The Magic Flute."
** And it's not too hard to see the influence of [[Anime/NeonGenesisEvangelion Komm Süsser Tod]] in the Food Chain song.

* In "Morituri Te Salutamus" just before one of the fighters dies, he says something along the lines of, "''[[EtTuBrute Et tu, Verus?]]''" which is a reference to ''Theatre/JuliusCaesar''.
** There's also Finn introducing Jake by saying [[MemeticMutation "Yes, this is Dog"]].

* In "Beyond This Earthly Realm", Jake sounds like [[Franchise/StarWars a Wookiee]] when he yawns.
** While we're talking about "Earthly Realm", Ice King says that Finn "[[Music/MCHammer can't touch this!]]"

** It also possibly pays homage to ''Literature/TheRoad'' as well as some zombie movies such as ''Film/TwentyEightDaysLater''.
** Probably unintentional, but the episode also seemed to have a few vague similarities to trailers for ''VideoGame/TheLastOfUs''.

* In "Puhoy", Finn comments that Jake's pillow fort is [[BiggerOnTheInside "Smaller on the outside"]], which are the words used in the ''Series/DoctorWho'' Christmas Special "The Snowmen" by current companion Clara Oswin Oswald.

* When Finn, Jake, and PB enter Wizard City in ''Wizards Only, Fools'', it looks like [[Film/HarryPotter Diagon Alley]].
** Also in "Wizards Only", the underwear thrown on Finn in prison might be a shout-out to the less child-friendly assault on Clarice in ''Film/TheSilenceOfTheLambs''.

* In "The Vault" The Regression sim game looks a lot like ''VideoGame/SuperHexagon''

* "Food Chain": Caterpillar-Finn and his bride Erin fall through the air holding hands like [[Anime/SpiritedAway Chihiro and Haku]] (or alternatively, like [[Anime/EurekaSeven Renton and Eureka]]).

* In the episode "Jermaine", the whoppin' big sword seen in Jermaine's house resembles Cloud's Buster Sword from ''VideoGame/FinalFantasyVII''.
** Also in "Jermaine", the teddy bear/cassette player may be a reference to Teddy Ruxpin, an animatronic toy extremely popular during the mid-1980s.

* In "Five Short Graybles" has Princess Bubblegum making a [[WallaceAndGromit familiar toothy smile]] while enthusiastically saying "CHEEEESE".

* The title of the Season 9 episode "Always BMO Closing" references the famous line "Always be closing" from ''Theater/GlengarryGlenRoss''. In the episode, BMO and Ice King pretend to be salesmen.
** At the end of the episode, Ice king says "[[Theater/TheIcemanCometh The Ice Man leaveth]]."

* In "Memories of Boom Boom Mountain", the Head Marauder calls Finn a "chicken" as he walks out of the village to see who is crying. Finn slowly turns around with a DeathGlare on his face and asks: "What did you call me?" This scene is VERY reminiscent of Marty [=McFly=]'s reaction to being called the same thing in the ''Franchise/BackToTheFuture'' trilogy. The fact that the Head Marauder is voiced by Thomas F. Wilson (aka. Biff Tannen) certainly helps.

* In "The Duke", one of the potions Finn and Jake are messing around with is labeled "[[WebOriginal/LOLCats Caturday Surprise]]."

* After being freed from prison in "What Have You Done?", the Ice King loudly proclaims "[[TabletopGame/DungeonsAndDragons CAST DETECT SECRET DOORS!]]" before blasting a hole to freedom.
** Mind you that happens in a room that has been proven to have at least 2 real hidden doors.

* Finn's plastic surgery turns Lumpy Space Princess into a [[WesternAnimation/DuckTales Gizmoduck]] lookalike.

** And Jake initially wants to wish for a sandwich, which was also Homer's attempt at a foolproof wish in the ''TreehouseOfHorror'' parody of The Monkey's Paw.
