Occam's Razor
One of the melee weapons called "Occam's Razor" is reference to the theory of William Ockham. His theory called Occam's Razor, boils down to "All other things being equal, the solution that makes the fewest assumptions is the best." In other words, when multiple competing theories are equal in other respects, the principle recommends selecting the theory that introduces the fewest assumptions and postulates the fewest entities. It is in this sense that Occam's razor is usually understood. Or, "all things being equal, the simplest explanation is usually right."

Lunchboxes
These Lunchboxes are actually available from the Collector's and Survival editions of the game, and can be made into an explosive. It isn't recommended that you turn your Lunchbox into an explosive in reality - that would be illegal in most countries and a waste of a perfectly good Collector's item.

Fear Factory Lyrics
In the main quest mission "Galaxy News Radio", you must go to the Museum of Technology. When you access the terminal in the northwest corner near the entrance, the first log entry dated 20770103 ends with "After a complete cleanup on the mainframe's core, I am happy to announce that the infection has been removed... the soul of this machine has improved. - B. Bell, Research Lead" This is a reference to the Fear Factory song, "Archetype", in which vocalist Burton C. Bell repeats the refrain "The infection has been removed, the soul of this machine has improved." This is evidenced by the fact that the mainframe is called the "Archetype Model FF06", Archetype being the album name, FF being Fear Factory, and 06 being the album number. Vocalist Burton C. Bell's name can also be abbreviated to B. Bell, to match the researcher's name in the terminal.

Lucy
In the town "Little Lamplight" the doctor, Lucy, is a reference to the character "Lucy" in the Charlie Brown comic strips and cartoons. Inside of the clinic where she is located, a sign reading "The Doctor is in" can be found, which was often seen on Lucy's stand in the series.

President Eden

V For Vendetta/Guy Fawkes
In vault 87, a character named Fawkes is trapped in cell 5. V was imprisoned in cell 5 (or V) until November 5th in V For Vendetta when he was burned to the point most of his facial features were no long recognizable. Also, his name is a tip to Guy Fawkes who attempted to blow up the Houses of Parliament on November 4th then hung and burned on the 5th, and is the basis for V for Vendetta. That is also one of the ideals V holds close, which he in the end he accomplishes blowing up Parliament but not before his death.

Rick Rubin

One of the notable ones is Harold who appears in Fallout 3 also

Dracula
Lucy West, the woman who kicks off the Blood Ties quest is probably a reference to Lucy Westenra, Mina Murry's friend in Bram Stoker's Dracula who's turned into a vampire and then staked by Van Helsing. The vampires choose to stay out of the sun much like movie versions of Dracula do.

Jericho
Jericho the mercenary in Megaton is probably a reference to the post apocalyptic television series of the same name.

Back to the Future
Butch DeLoria seems to be a clone of the past version of Biff. Further DeLoria is probably a reference to the DeLorian, the car used as a basis for the time machine.

Blade Runner
Chief Harkness in Rivet city is a reference to the movie Blade Runner. The title of his quest is "The Replicated Man". Fans of the Blade Runner movie can see obvious parallels within the quest.

H.P.Lovecraft's Dunwich Horror
In the extreme southwest of the world map you can find "the Dunwich Building,, which once housed the offices of a pretty innocuous company (Dunwich Drilling, a manufacturer of industrial mining and drilling machines). This is possibly the single "creepiest" or "spookiest" location in the game, as the ruins now form a very dark, chaotic three dimensional maze absolutely chock-full of feral ghouls.  The personal logs you find here and an object you find at the very end of the maze form a definite reference to Lovecraft's Cthulhu mythos/setting.  The name of the location itself is a direct reference to Lovecraft's The Dunwich Horror.

Transformers
When following Liberty Prime to the Memorial in the first part of the quest Take it Back!, the robot Liberty Prime can be heard shouting "Freedom is the sovereign right of all Americans", a direct reference to Optimus Primes's famous quote, "Freedom is the right of all sentient beings".
