Community:Fallout 76 Easter Eggs

Alien
In the AVR Medical Center, one can find a Jangles the Moon Monkey doll lying on a stretcher with a toy alien attached to its face on the first floor, reminiscent of a facehugger from the Alien franchise.

Albert Einstein
Inside the doghouse of the isolated cabin is a mathematical formula written in chalk: $$R_{\mu \nu} – \tfrac{1}{2} R g_{\mu \nu} + \Lambda g_{\mu \nu}  = \frac{8 \pi G} {c^4} T_{\mu \nu}$$. This is an Einstein field equation, first published by Albert Einstein in 1915.

Breaking Bad
Just north of Sugar Grove, there are several partially buried blue barrels with money on top of them and a skeleton nearby in a lab coat. This references the scene from Breaking Bad in which Walter White buries barrels full of money in the desert.

Distant Drums
The memetic "Wilhelm Scream" is briefly heard in a promotional video for Fallout 76.

Doom
A set of wooden blocks in the apartment building with the Nuka-Cola billboard on the east side of Morgantown spells out "BFG," a reference to the weapon first appearing in the Doom franchise, published by Bethesda Softworks since 2010.

The Elder Scrolls V: Skyrim

 * The raid decals used by the raiders are strikingly similar to the Shadow marks used by the Thieves Guild in Skyrim, down to sharing the "loot" and "empty" marks.
 * At the Mount Blair trainyard, there is a series of wooden blocks that spell out "WE KNO" next to a framed picture with a bloody handprint on it. This is a reference to the Dark Brotherhood's mysterious note in Skyrim.
 * On a path west of Vault 96, there is a carriage carrying three dead settlers that resembles the intro scene of Skyrim. It is a possible location to wake up at after drinking Nukashine.
 * One question in the Medic Pioneer Scout exam involves a patient that has been shot in the knee. One incorrect answer is to "advise Ricky to give up on adventuring," a reference to the memetic line "I used to be an adventurer like you. Then I took an arrow in the knee..."

Fallout: New Vegas
One of the raider tribes that previously existed in Appalachia was the Gourmands. This appears to be a reference to the White Glove Society and their restaurant The Gourmand, that previously appeared in New Vegas, given the preference of both groups for eating human flesh.

Harley-Davidson
Harley Wheeler, a prisoner at Eastern Regional Penitentiary, was sentenced to seven years imprisonment for five counts of grand theft auto. Considering their name and crime, Harley is most likely a reference to Harley-Davidson, Inc., a motorcycle manufacturing company.

Headlight fluid
Headlight fluid, a trolling bait and meme used to send someone on a search for something that doesn't exist, is referenced in the R&G Processing Services terminal entries, when Manager Jarrett Delgado suggests giving a job to Pat Rhodes involving the nonexistent item. Headlight fluid was popularized through its appearances on radio shows and the Rooster Teeth series Red vs. Blue.

Google Home argument
The random encounter with two Mr. Handy's talking back and forth in an endless loop is a reference to a January 2017 video stream of two Google Home devices (also named Mia and Vlad) stuck in a loop asking each other questions.

It
Inside of a fridge at the Whitespring golf club, there is a clown holding a red balloon in reference to Pennywise the Clown from Stephen King's It, who is often menacingly portrayed with a red balloon.

Jim Croce
Leroy Brown, a guard at Eastern Regional Penitentiary, shares a name with a character in the song "Bad, Bad Leroy Brown" by Jim Croce.

The Legend of Zelda
Vendor bot Raiders reference a famous line in The Legend of Zelda, saying "it's dangerous to go alone."

Loss.jpg
There is a picnic table at a campsite west of the pumpkin house with seven beer bottles on it that are positioned in reference to "Loss," an infamous comic that often takes a minimalist form in Internet memes, using just seven lines in a sequence.

Monster Factory
Near the Kanawha Nuka-Cola plant, there is a house the references the webseries Monster Factory by Polygon. There are several characters from their Fallout 4 series at the house.

Monty Python
The lumberjack protectrons at Gilman lumber mill will occasionally say "Lumberjack protectron works all night and also works all day," a variation on a line from "The Lumberjack Song."

Murdoch Mysteries
At the Top of the World, there is a customer comment terminal. One of the entries contains references to the CBC mystery show Murdoch Mysteries. The heading reads "W. Murdock & J. Ogdin," which are references to the titular character of the television show (William Murdoch) and his wife, Dr. Julia Ogden. The text also refers to a "Crab-tree Burger," which is a reference to another character on the show, George Crabtree. Finally, one of the burger ingredients is listed as "Canadian Bacon," which is a nod to the show's origin and shooting location.

The Office
In the Camden Park terminal entries, Marty Porkins is promoted to the position of Assistant to the Park Manager, before the title is changed to Assistant Park Manager. This is a reference to a running gag from The Office, in which Dwight Schrute (in the U.S. version) or Gareth Keenan (in the U.K. version) repeatedly claims that he is the Assistant Regional Manager, forcing others to correct him with his actual position, the Assistant to the Regional Manager, a much less valuable title.

Peanuts
In the woods near Vault 76, there is a doghouse with a skeleton sprawled on its roof, baseball items lying on the ground outside and a birdhouse on a nearby tree. These are references to Snoopy, Woodstock and other characters from the comic strip Peanuts.

Star Trek: The Next Generation
Tanagra Town and the "Darmok + Jalad" graffiti in the bus stop are references to the Star Trek: The Next Generation episode "Darmok."

Throw Momma from the Train
The note Untitled is a reference to the opening scene of Throw Momma from the Train, in which character Larry Donner suffers from writer's block and can only come up with "The night was" on his typewriter.

Toy Story

 * East of Bleeding Kate's Grindhouse, there is a Comrade Chubs teddy bear sitting on the front of a truck on the highway. This is a reference to the ending of Toy Story 3, where the antagonist, teddy bear Lotso, is found by a trucker and tied to the front of his vehicle.
 * In the Whitespring Resort, there is a large toy shop in which block letters with the words "Syd" may be seen. This is a reference to the character from Toy Story.

We Bare Bears
In a tower at the Palace of the Winding Path, where the child's note is found, there is a stack of three teddy bear variants that resembles the main characters of We Bare Bears, an animated television series that began airing in 2015.
