The entire game is crammed with them, to the point that it's easier to list which parts of the game ''aren't'' {{Shout Out}}s. Also, we have nowhere near all of the shout outs, so this page will take a very long time to be finished. A [[strike:few]] bunch of examples, sorted by reference subject:

[[foldercontrol]]

[[folder: Anime and Manga ]]

* If a player gets more than 9000 kills online, his profile will read "Kills [[Anime/DragonBallZ Over 9000]]".
* "This is not a planet of [[{{Trigun}} peace and love.]]"
** One of the challenges for inflicting damage is "Human Tsunami". In the series, the main character is believed to be so destructive, he's classified as "The Humanoid Typhoon", making him the first human being to be registered as a natural disaster.
* The black Runner color-scheme names it [[Anime/SpeedRacer "Vehicle X"]]. The black Racer is the X-Racer.

** Plus, the Firefly class mod for Lillith, resident supernaturally-powered girl who specializes in close-quarters combat.
* The [[Franchise/ScoobyDoo Misery Machine]] and anything related to it in ''The Zombie Island of Dr. Ned''. [[http://www.youtube.com/watch?v=bzT85VMiHiw&feature=related An ECHO had one of the former occupants exclaiming Shaggy's trademark "Zoinks!" - and he has a pet skag named Skaggy.]]
** Crazy Earl's little "lap-skag" is called Skrappy.
* In the hospital part of DLC 1, the hospital's name is [[Series/GeneralHospital Generally Hospital]]. And appearance-wise, the hospital is [[Series/TheAddamsFamily creepy and kooky, mysterious and spooky.]]

* "[[Series/StarTrekTheOriginalSeries Damnit Claptrap, I'm a doctor not a mechanic!]]"
* Interplanetary Ninja Assassin Claptrap's habit of calling humans "Fleshbags" may be a reference to ''{{Lexx}}'', in which the cannibalistic Giggerota refers to other humans as such. Alternatively, it may be a reference to something else entirely (see the Video Games entry below).

[[/folder]]

[[folder: Film ]]

* Patricia Tannis says "We'll need a nuclear reactor to generate the [[Film/BackToTheFuture One point twenty-one jiggawatts]] -- Oh, hey!"
* When you talk to Mr. Blake in the ''Robot Revolution'' DLC, he says that without phase one complete, there can be no phase two or three, and [[Film/MontyPythonAndTheHolyGrail phase four is right out]].
* The hidden basement has a leg lamp, a Christmas tree, and a bee bee gun like in AChristmasStory.
** The Rider: You might put someone's eye out.

* [[JohnWoo The Dove.]] [[BottomlessMagazines "Sometimes, I forget to reload."]]
* The Torgue Violator ([[Film/RoboCop1987 "Your move, creep."]]) as well as the Torgue Cobra ("I LIKE IT!", a reference to the [[{{BFG}} Cobra Assault Cannon]] from the movie and the thug who was more than happy to test it out.)
* The S&S Gemini ([[ComicBook/JudgeDredd "Double Whammy"]])
** During the quest he appears in, the PlayerCharacter has to collect poisoned cigars because "some kid could find them".
* The game even has pure visual shoutouts - the Crimson Lance comes with posters that reference Film/{{District 9}}. Considering D9 came out only a few months before the game did, Gearbox was essentially adding in new art assets and shoutouts right up to the last possible moment.
* The [[Film/{{Spaceballs}} Ludicrous Speedway]]

** The challenge of shooting 25,000 times is titled "Who made that man a gunner?"

* [[MadMax Mad]] [[Creator/MelGibson Mel]].
** Before facing him, the player is forewarned that he is a "LethalWeapon" in any vehicle, and after his defeat Helena is thankful that somebody "with a Film/{{Braveheart}}" stood up to him.
** The fact that he's a vehicular combat expert is probably at least a little in reference to Mel Gibson's infamous drunk driving incident. Or maybe he's just a [[MadMax Road Warrior]].
* The Pestilent Crux Shotgun has the caption [[Film/MontyPythonAndTheHolyGrail Bring out your Dead!]]
* The Eridian Lightning has the caption "I feel like [[Film/MenInBlack I'm gonna break this damn thing]]"
* The Chiquito Amigo's 'Say "Hello"' caption seems innocuous enough, until you take into accound that Chiquito Amigo translates as 'Little Friend' to which you realise its a subtle reference to [[Film/{{Scarface}} Tony Montana's]] infamous line "Say Hello To My Little Friend!"
* The quote for the Hyperion Invader "BAM BAM BAM BAM BAM!" resembles a scene in the movie ''Film/ReservoirDogs'' where hired gun Mr. White, furious at Mr. Blonde's earlier shooting of several hostages, re-enacts the scenario by using his hand as a gun and shouting "BAM! BAM! BAM! BAM!"

* Steele-Trap says "[[KneelBeforeZod Kneel before Steele]]" while fighting her.
* A (falsely) injured rebel Claptrap you can save sings "[[Film/TwoThousandOneASpaceOdyssey Daisy, Daisy, give me your answer do...]]"
* [[Franchise/{{Godzilla}} Skagzilla]] and [[{{Mothra}} Mothrakk]].
* The achievement/trophy entitled "[[Film/MontyPythonAndTheHolyGrail There Are Some That Call Me... Tim.]]"

* One of the challenges for buying and selling items is titled "[[TradingPlaces How Much For The Gun?]]"
* In ''Claptrap's New Robot Revolution'' Tannis babbles something about re-routing the [[Film/GalaxyQuest Omega 13]] to the snooze button.
* Yet another of Tannis' Robolution request is for "[[Film/{{Ghostbusters}} parts to ensure the protection grid holds on her device's ecto-containment unit, safeguarding against total protonic reversal, which would be extraordinarily bad]]."
* The achievement for killing 25 enemies with shock weapons is named [[Film/BackToTheFuture 1.21 Gigawatts]].
* The legendary pistol [[Film/TakeTheMoneyAndRun Gub]], which has the special weapon effect "Abt Natural."

[[/folder]]

* There are a large amount of Shoutout to Franchise/TheHitchhikersGuideToTheGalaxy. One of the Claptraps you can rescue repeats nearly word-for-word Marvin's speech when he first meets Arthur Dent. And I've seen a couple of signs that say "Don't Panic", in large friendly letters to boot.
** Tannis needs you to get parts for her Infinite Improbability Drive in ''Claptrap's New Robot Revolution''.

* Written on the walls of some of the early houses are the words "turtles all the way down".
* Whitting's Elephant Gun could be based on Ernest Hemingway's "Hills like White Elephants". Evidence of this includes: 1. The gun's name is "Whitting's Elephant Gun", which could reference "Hills like White Elephants" 2. Ernest Hemingway was a noted "Big Game Hunter", which is also the title of the mission where you have to kill Skagzilla, which leads to you acquiring the gun as a reward and 3. The mission is given by a man named Ernest Whitting.
* The mission in DLC 4: [[ComicStrip/SpyVsSpy "Spa vs. Spa."]]

[[/folder]]

* The game opens with the Guardian Angel saying "[[VideoGame/BioShock1 Would you kindly]] fix that poor robot?".
** The audio recorders look a lot like the ones you would find in Rapture, as well.
** [[http://borderlands.wikia.com/wiki/Power_To_The_People This quest]] could very well be a reference to the shops found throughout Rapture.
** Atlas is in control, and it initially seems to be helping you (well, the guns, anyway), but later it's trying to kill you.

* The [[VideoGame/CallOfDuty Circle Of Duty]] missions in DLC 3; the last mission is even called "Circle of Duty: [[MedalOfHonor Medal of Duty]]"
** In the second game, Axton has an ability in his Gunpowder tree called Ranger. Its icon is two crossed rifles resembling the M16 with a star next to the top, left and right sides of the rifles. The RealLife U.S. Army Rangers do not have any sort of logo, but [[http://images.wikia.com/callofduty/images/2/2f/Rangerslogosp.png they get a similar one]] within VideoGame/CallOfDuty: ModernWarfare2.
* [[VideoGame/HouseOfTheDead House of the Ned]] in DLC 1.
* The Torgue Twisted [[strike:Redeemer]] Redemption has the caption [[VideoGame/UnrealTournament "Monster Kill!"]]

* The challenge award for gets 250 kills with Incendiary weapons is named "[[VideoGame/MortalKombat Toasty!]]"

[[/folder]]

[[folder: Tabletop RPG ]]

* The Powered Armour suits used by the crimson lance in the latest DLC look an awful lot like [[TabletopGame/{{Warhammer 40000}} Adeptus Astartes power armour]], also the suits care called 'devastators' which happen to be names of the Adeptus space marines who carried the biggest guns.
** Once the Crimson Lance start spawning in the Salt Flats, they are surrounded by what look like very thinly disguised [[TabletopGame/{{Warhammer 40000}} Space Marine]] drop pods.

[[/folder]]

* Mad Moxxi's first husband is described as a cheat. In the cutscene, he is killed with the KonamiCode.

[[/folder]]

[[folder: Tarot ]]

* [[TarotMotifs Tarot cards]] get a shout out when you find [[spoiler: T.K. Baha]]'s body in a position almost exactly like The Hanging Man.

[[/folder]]

[[folder: Real Life ]]

* The Atlas Patton. ("May God have mercy on my enemies, because I won't" was supposedly said once by General George S. Patton, hence the name. TheOtherWiki claims it was also once uttered by Queen Elizabeth the First.)
** Double reference in that the Patton ''always'' spawns as a revolver with a nickel-plated body and an ivory grip, referencing the two revolvers (in the same style) which Patton himself owned.
* The two "Claptrap, Behind the Scenes" miniclips are {{Shout Out}}s to the infamous Creator/ChristianBale rant.
** The second one also contains a shout out to the infamous [[Series/TheOReillyFactor Bill O'Reilly]] rant, "We're doing it live!"
* When one of the rebel Claptraps die, they might say "I see three... flashing red lights..." [[{{Xbox360}} Now what does that sound like to you?]]
* Roland and Axton have an ability called Metal Storm [[http://en.wikipedia.org/wiki/Metal_Storm Metal Storm which is also the name shared by a weapons company]].
* Whitting's Elephant Gun: an Elephant Gun is actually a real life type of rifle for hunting big game (e.g. [[CaptainObvious elephants]]), Skagzilla could easily be classified as such.

* In DLC 3, at "Road's End", the player will spot a highway sign reading "Fort Knoxx - 20km". Fort Knox is an actual United States Military post, known for its proximity to the United States Bullion Depository. General Knoxx's unique, highly-valuable pistol ("Knoxx's Gold") is a further reference to this location.
* There is a location on Pandora known as "Treacher's Landing", which is a possible reference to Arthur Treacher's chain of seafood restaurants.
* You fight a massive Scithid on the [[WhoShotJFK "Trashy Knoll".]]
* Marcus wants you to gather up Skag musk-glands and Rakk-hive ambergris to brew up a "...truly potent cologne." The mission name? "Old Spicy".
** So, [[{{Anchorman}} does it smell like pure gasoline?]]
* One of the challenges for scoring kills is titled "Your Kung-Fu is Best". This is a reference to [[http://en.wikipedia.org/wiki/Kevin_Mitnick Kevin Mitnick]], a computer security consultant and author. He was previously a well-known computer hacker and 'phreaker', and prior to his arrest, he left a message on the investigating detective's answering machine, stating "My kung-fu is best!"
** Another challenge (this one for dealing Shock damage) is titled "UsefulNotes/NikolaTesla is a friend of mine."
** Yet another (for sheer number of enemies killed) is titled "Now I am become Death...", a phrase uttered by J. Robert Oppenheimer.

--> More than a few brave men have turned chicken at Sanders Gorge... and even more have made that truly awful joke.
