Borderlands pop culture references

There are a number of pop culture references (memes, movie references, etc) in the game:

A Brief History of Time
Graffiti found on walls: "Turtles all the way down"

The phrase "Turtles all the way down" comes from a tale most popularly related in Stephen Hawking's book A Brief History of Time:

"A well-known scientist (some say it was Bertrand Russell) once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: "What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man, very clever", said the old lady. "But it's turtles all the way down!""

This could also be a reference to a number of the Discworld novels by Terry Pratchett, primarily Small Gods, where the world is supported by four elephants on the back of a turtle, the great A'Tuin.

Additionally, this could refer to the children's book Yurtle the Turtle by Dr. Seuss. In the book, the king of the turtles, Yurtle, rules all he sees, but being a turtle, he can't see very far. He then has the idea to have all of his subjects, other turtles, climb up onto each other's backs, with Yurtle finally being on top, enabling him to see farther. Yet because all these turtles are piled on top of each other, they get very tired and hungry and start to complain, and eventually one plain little turtle named Mack burps, and all the turtles come tumbling down. This has often been compared to any sort of dictatorship and its eventual collapse.

The Canterbury Tales
Weapon: Lady Finger

The Canterbury Tales is collection of stories by Chaucer, about a group on pilgrimage to Canterbury Cathedral. This serves as a frame for shorter stories about the individual characters. "The Prioress's Tale" tells the story of Madam Eglantine, who wears a ring with the inscription "Amor vincit omnia", which translates into "love conquers all". The flavor text of the Lady Finger, Omnia Vincit Amor, means the same. The name Lady Finger may refer to the fingers of the prioress, where the ring was worn.

The Dark Tower
Character: Roland

Roland shares his name with the protagonist from the series of books "The Dark Tower", written by Stephen King. Many other themes and terms are shared, such as the Hunter's fighting bird (David in The Waste Lands).

Coincidentally, Mordecai's Gunslinger COM improves the use of Revolvers, which not only are Roland's (Dark Tower Roland, not BL) preferred weapon, but also affixes the title of Gunslinger, by which DT Roland is formally addressed.

Dragon Ball
Character: Crazy Earl

Crazy Earl is referred to as a "turtle hermit," and Tannis claimed to have given him her underwear. This is a direct reference to Master Roshi in the Dragon Ball comics. Master Roshi sometimes wore a turtle shell, and he collected women's underwear.

Chuck Durden refers to Fight Club. Chuck Palahniuk wrote the book, and its main character is Tyler Durden.

Frankenstein
Enemy: Tankenstein

The name Tankenstein is a reference to Frankenstein's monster in Frankenstein; or, the Modern Prometheus by Mary Shelley. Its appearance matches the widely accepted appearance of the creature. Tankensteins are healed by Shock damage; in the book Dr. Frankenstein uses power harnessed from lightning to reanimate a corpse.

The Hitchhiker's Guide to the Galaxy franchise
Character: Lucky Zaford

His last name is a reference to the characters Zaphod Beeblebrox and Ford Prefect.

Claptrap (Old Haven): "I think you ought to know I'm feeling very depressed."

A phrase often said by Marvin, the depressed robot in Hitchhikers Guide To The Galaxy. The entire speech of this Claptrap is very similar to how Marvin feels in the book and the rest of the series.

''Taylor Kobb's Hacked Claptrap: "... OR... I could stick an electrode up my back panel and call it paradise." ''

Refers to a ploy by Ford Prefect, one of the main characters, in which he disables a security bot by short circuiting its decision making processes, located in a back panel, causing it to find everything impossibly pleasurable.

How Much for Just the Planet?
The "How Much for the Planet?" challenge may refer to How Much for Just the Planet?, a humorous Star Trek tie-in novel by the late John Ford.

Merchant of Venice
Psycho: "Now it's time for my pound of flesh!"

Refers to Shylock's line in the play Merchant of Venice by William Shakespeare. In the play, a "pound of flesh" is to be the payment to Shylock from his client for defaulting on a loan.

Moby Dick
Mission: T.K.'s Life And Limb

Baha is Ahab backwards, and in the book, Ahab was driven mad to find and kill the White Whale after his leg was taken from him. Scar also has several weapons embedded into his head, and is extremely tough. Moby Dick was described as having several harpoons in his head, and numerous scars from where many sailors tried, and failed, to kill him.

BioShock
Guardian Angel: "Would you kindly give him a hand?"

This quote is the trigger to the first Claptrap Rescue mission. The phrase "Would You Kindly" was the trigger phrase used by the main antagonist of BioShock, another game published by 2K Games, to force the player's character to perform actions. As with Bioshock, the storyline will not advance until you have completed this mission.

Blaster Master
Blaster Master Outrunner color

The name for this color is a reference to a NES game with the same name, featuring a buggy-like tank with a red color scheme.

Gauntlet
Mission: Earl Needs Food... Badly

In the old coin-operated arcade game Gauntlet, each of the four characters would receive a unique spoken warning when their life was running low. The Elf's warning message was "Elf needs food, badly!".

Half-Life Series
Mission: House of the Ned

Towards the end of the mission, the player has to wait for a slow, hand-cranked elevator while fighting off zombies, something that happens fairly often in the Half-Life titles. Dr. Ned pokes fun at the situation by implying this isn't the first time you'd likely have waited for an elevator during a zombie outbreak.

Halo Series
Enemies: Lance Probe

These enemies have almost identical sounds in regards to their hover jets that they use to fly and their voices, resembling the oracle from Halo.

House of the Dead
Mission: House of the Ned

House of the Dead is an arcade game developed by Sega. Players take on the role of agents trying to kill the monsters created by Dr. Curien, a scientist who tried to discover the nature of life and death, but his experiments resulted in dangerous monsters.

However, it is also possible that the title may be intended to refer to the 1862 novel The House of the Dead by Fyodor Dostoyevsky. (Though given that the book has nothing to do with zombies, it is fairly unlikely.)

Left 4 Dead
Challenges: I hate dogs; I hate bugs

The challenges title might be a reference to Francis from Left 4 Dead. The biker is famous for his "I hate ___" quotes.

Metal Gear Solid 2
Level Cap (as of Gen. Knoxx DLC)

The level cap of 61 is possibly a reference to a notable scene in Metal Gear Solid 2, where upon Raiden's journey into Arsenal Gear, Colonel Campbell speaks strange phrases -- one of them being "I need scissors! Sixty-one!" The MGS2 scene in question can be watched here

'''This might also be a reference to the number of Saturn's moons, total of 61, and one of which is named Pandora. '''

(Alternatively, the 11 extra levels might be a reference to the phrase "These go to eleven", which stands for exceeding expected mileage from equipment and was first uttered in the film This is Spinal Tap, where a guitarist shows off volume knobs that go to eleven.)

Portal
Challenges: Whats in here

The challenges title might be a reference to one of the emotions cores that fall off of GlaD0s, the curiosity core says multiple things in a funny voice and one of the things being "Whats in here?"

Ratchet and Clank
Weapon:Maliwan Rhino

Example: http://ratchet.wikia.com/wiki/RYNO_V

The most powerful weapon in the Ratchet and Clank series, it is commonly a mini gun rocket launcher with numerous barrels (An overkill weapon). R.Y.N.O in the Ratchet and Clank series means: “Rip You A New One”, it is known to be the 'deadliest weapon in the known universe' according to GrummelNet. In Borderlands it is the brand name for the most powerful rocket launchers made by Maliwan as an homage to the Ratchet and Clank series (it is also the most powerful rocket launcher brand in the game, following the tradition of the RYNO series).

Sonic the Hedgehog
Paint Scheme: Racer - Blue Blur

Sonic the Hedgehog, from the self-titled series, is as his name would suggest, a hedgehog. Sonic is capable of phenomenal speed, provided he doesn't stop or collide with anything. One of Sonic the Hedgehog's nicknames is 'The Big Bad Blue Blur', and the Racer's Blue Paint-Scheme is thus named after him.

All Your Base
Mission: Dumpster Diving For Great Justice

Based on part of a popular internet meme stemming from wrongly translated phrases in the game Zero Wing. The Japanese to English translation resulted in such sentences as, "All your base are belong to us". The phrase "For Great Justice" was supposed to be "Our hopes for the future..."

Mission: Athena Set Up Us The Bomb 

The title of this mission likewise mimics the Zero Wing mistranslation, "Someone set up us the bomb."

Ding!
'''Achievement - Ding! Newbie'''

In many RPG, CORPG and MMORPG games, players develop characters through a series of increasingly difficult levels. Thresholds in character development are marked by character levels and increases in level are often marked with a bell or electronic chime sound. Players commonly mimic such sounds by verbalising, or typing, the word "Ding!" to announce their character's level increase to their teammates.

Group LF Healer
Achievement - Group Lf Healer

Some games, particularly MMORPGs, have support archetypal characters. These 'healers' are often highly valuable parts of a party's composition, resulting in many groups waiting for healers and advertising with lines such as, "Group LF Healer!" (Abbrev: Group looking for healer)

The Meat Puppets
One of psychos' battle yells is "Time to pound the meat puppet!" This could be a reference to the rock group the Meat Puppets, or to subsequent uses of the term. Cyberpunk author William Gibson was inspired by seeing the name of the band in print to borrow the term to apply to a form of prostitution in which the prostitute had a neural cut-out chip installed that would let someone rent out their body under computer control while their mind was occupied in cyberspace. More recently, the term has been applied to a form of "sockpuppet" (a participant in an on-line discussion under false pretenses).

This is a quote from the character Hudson.

Avatar
General Knoxx could be a possible reference to Colonel Miles Quaritch in Avatar. Knoxx's lines similar to the Colonel; "Kill them all, it's the only fair thing to do.", "It's a shame you would have made a fine soldier."

Also the Devastators have a surprising like-ness to the movies AMP suits.

Back to the Future
Achievement: 1.21 Gigawatts

1.21 Gigawatts is the power requirement for time travel. Although in the Back to the Future movie series, from which the reference originated, it is pronounced as 1.21 Jiggawatts, perhaps lending itself to mean a much larger amount of energy, as it is seen as almost insurmountable as Doc remarks that "the only thing with that kind of power would be... a bolt of lightning."

Star Wars
Taylor Kobb: "a hive of scum and villainy" 

Obi-Wan Kenobi calls the Mos Eisley space port "a wretched hive of scum and villainy" in the original Star Wars movie, Star Wars Episode IV: A New Hope.

The opening scene, where Clap Trap hits his head on the opening gate of Fyrestone is similar to the Storm Trooper hitting his head on the door of the Death Star as they enter the room with C3P0 and R2-D2 (though it could just simply be an unrelated bit of slapstick comedy).

This Is Spinal Tap
The dials on Marshall amplifiers typically have a number range from zero to ten. In the mockumentary This Is Spinal Tap Guitarist Nigel Tufnel boasts that the dials on his amps all go to eleven. This forms the inspiration for the level cap increase by 11 in The Secret Armory of General Knoxx.

The Thaw
House located in Dahl headlands next to the race track with insects and dead bandits inside

Muhammad Ali
Brick's skill, "Sting like a Bee" could be a reference to one of Muhammad Ali's most famous quotes, "Float like a butterfly, sting like a bee."

Adolf Hitler
Crazy Earl has a moustache identical to Adolf Hitler's. Despite also being worn by comedy icon Charlie Chaplin, the social stigma now associated with the tiny, little moustache means only the most maladjusted would ever wear one again.

Fidel Castro
The image of DLC 4 has a claptrap that looks identical to Fidel.

Lynn Abbey
"Old Lynne Abbey" from Altar Ego: The New Religion may be a reference to fantasy author Lynn Abbey.
