List of Easter eggs in The Sims

An Easter egg is a message hidden in the object code of a program, movie, book, CD, DVD, or video game as a joke, intended to be found by persons disassembling or browsing the code.

There are many Easter eggs in The Sims series. Some of these are hidden in the actual game play and others are hidden in the code.

 * There are several references to the game's creator, Will Wright, including the doll house and the "Whack-A-Will" game from Vacation.
 * The baby doll souvenir from Vacation bears a striking resemblance to the default look of babies in The Sims 2.
 * The "rosebud" cheat might be a reference to the movie Citizen Kane.
 * The "klapaucius" cheat might be a reference to Stanisław Lem's book The Cyberiad and one of its protagonists, the constructor Klapaucius.Hiddenpicturelauncher.PNG
 * If there is a Christmas tree, fireplace, and a table with cookies in the same room late at night, Santa Claus will come, and leave the family a present.

The Sims 2

 * Bella Goth: There are many references to this mysterious Sim in the game. Bella Goth appears on the milk cartons and newspapers in the game. It is rumored that Bella and her brother Michael are standing in the hot air balloon neighborhood object in the game; others suppose this is the Dreamboat and Blonde Bombshell townie characters from The Sims: Hot Date expansion pack. Bella appears in many of the decorative photographs of the game, one being a picture of herself named "Bella Squared". She is also a townie in Strangetown. Belladonna Cove has a statue of Bella holding a PlumbBob. In The Sims 2 for PlayStation 2, the name of a refrigerator is "Chow Bella Bachelor".
 * Onomatology: Several pre-made Sims in the game have puns that allude to a meaning as a name. For example, Rigger Mortis and Earl E. DeMise.
 * Hidden Painting: There is a painting hidden within the game's files that depicts an 18th-century couple. The couple in the painting closely resembles Glenda the Ghost and Gordon the Ghost (NPC ghosts from The Sims Makin' Magic).
 * The Pleasant Family on TV: The Pleasant family appears in commercials on TV. One of the clips depict the two sisters fighting and Daniel making out with another woman. The second commercial advertises a pizza delivery chain.
 * Freezer Bunny: It represents a pink bunny cartoon and first appears on the back of a juice carton in the community lot freezers.
 * Simpsons House: A house on the train table in The Sims 2: FreeTime bears a striking resemblance to 742 Evergreen Terrace, the house of the Simpson family.
 * The Flying Pig: A neighborhood object released with The Sims 2: Open for Business. Appears in neighborhoods with a water tower. It also appears as a decoration on a tree in the FreeTime train table. This may be a reference to Pink Floyd, after an inflatable pig broke free during production of one of their albums.
 * The Spaceship: A neighborhood object/event released with Pets. When a crashed spaceship is placed in the neighborhood, a spaceship arrives with a searchlight to find the crashed ship.
 * The Spaceship's License Plate: Says 'anm8er' (It sounds like "animator"). When an abduction occurs on the lot and the UFO comes to return the Sim, the license plate can be seen.
 * Grim Reaper's Bio: When using the  cheat to view the Grim Reaper's bio, it says that his favorite band is Styx. Note that doing this will corrupt your game.
 * Santa Claus's Bio: When Santa is made selectable and his biography is viewed, it reads, "The Big Man". Please note that doing this will corrupt your game.
 * Hidden Lot in Belladonna Cove: There's a hidden lot at the edge of Belladonna Cove, called Watervista Palace. It can only be seen by using the cameraman mode (Tab), or by using a camera mod that allows the camera to view the edges of the neighborhood. It resembles Baba Yaga's hut.

This is possibly a reference to the ongoing critical debate over the possible sexuality of William Shakespeare, on whose life and plays the neighborhood is based. It could also be referring to the fact that, in Shakespeare's day, only men were allowed to act.
 * Hot Dog Stand Counter: On the counter of the hot dog stand in Apartment Life, players can see some recognizable pictures. The pictures include the photos from the photo album of the Smith family, the Grunt family, the Lothario family, the Broke family, and many more.

 * Phone Book Cover: The phone book children use when playing chess contains a cover with alphabet on it, despite the fact there's also Simlish on it. It says a series of "asdfsf dfasd asdf." It can be implied that the developer only added random letters while designing the phone book.
 * Video Game: A preview of The Sims 3 in its beta version appears as a video game that is shipped with FreeTime.
 * Sir Bricks-a-Lot: One of the toys that can be crafted in Open for Business is Sir Bricks-a-Lot. This is a play on Sir Mix-a-Lot, who is an African-American rapper/songwriter.

 * Chance Cards: The chance card for the Master of Ceremonies position in the Entertainment career track refers to The Simmy Award from The Sims: Superstar.
 * Job Titles:The "Dread Pirate" job in the Adventurer career track is likely a reference to the Dread Pirate Roberts in The Princess Bride.
 * Wall Lamp: One of the wall lamps is called "Prisoner of Azkalamp". This is a reference to Harry Potter and the Prisoner of Azkaban, the third novel in the Harry Potter series by J.K. Rowling.
 * Floor Lamp: There is a floor lamp called "Rave Against the Machine", a reference to popular American rock band Rage Against the Machine.
 * Desk Lamp: One of the desk lamps is called "Pix-Arm Drafting Lamp". This is a reference to Luxo Jr., the mascot of the Pixar Animation Studios.
 * Dresser: One of the dresser is called "Hold Me Closer" by the "Tiny Dresser Co.". This is a reference to Elton John's song Tiny Dancer with the lyrics Hold me closer tiny dancer.
 * End Table: There is an 8-sided end table called 'Crazy 8'. Crazy Eights is a simple card game. This could also be a reference to the 'crazy 88 gang' from the film Kill Bill vol. 1.
 * Whistling: Sims with enough Music and Dance enthusiasm will occasionally whistle a segment of the buy mode song from The Sims.
 * Teasers: There are two teasers in FreeTime that hint to The Sims 3 prior to its release. The first one is a poster with a green PlumbBob of The Sims 3 logo. The second one is a painting with two presets, one of which closely resembles Sunset Valley, albeit with differences.
 * Stonehenge: One of the new neighborhood decorations in The Sims Castaway Stories is an exact replica of Stonehenge.
 * Dummies: The white bus used as a carpool in the athletic career has two Sims inside that closely resemble children from The Sims. They are not real Sims, but are "dummy" Sims, and exist only as a texture.
 * Unlikely Whale Sculpture: The sculpture's description refers to The Hitchhiker's Guide To The Galaxy, in which there is a section based on a sperm whale and a bowl of petunias being called into existence high up in the sky. In the book, the whale ponders who it is and it's purpose in life whilst falling, which the description alludes to.
 * The Aerodynamo: The description of this item, specifically the reminder to not use it as a giant fan, refers to this scene from the animated TV series Futurama.
 * Servo: The cost of building a Servo in The Sims 2: Open for Business, §3000, is a possible reference to Tom Servo, a robot from the TV series Mystery Science Theater 3000.
 * West End Girls: The song "Suburbia" by West End Girls, which was included in non-US releases of The Sims 2: Pets is a Simlish cover of the song of the same name by the British synthpop band Pet Shop Boys. The band West End Girls was also named after a Pet Shop Boys song.

Sims

 * Vincent Skullfinder, from MySims, is a deceased Sim buried in Pleasant Rest Graveyard.
 * The Goth family is incomplete. There is a Sim in Goth's graveyard named Lolita Goth. Some players believed that she is Gunther's sister, in replacement of Frida Goth, because Frida didn't appear in The Sims 3 yet, only until she reappeared in Supernatural. Some players believe that Lolita is Gunther's ex-wife. For theories, see Lolita Goth/theories.
 * In Late Night, there is a possibility that Sims will exclaim, "This place is hotter than Hank Goddard that one time he caught on fire!" when visiting a random hotspot. It is also possible they will exclaim "This place is as hot as Connor Frio with a bad case of hypothermia".
 * Some worlds have an abandoned mine somewhere in the town. The abandoned mine has a blocked entrance, scattered pickaxe, lantern, and eerie glowing eyes inside the mine.

 * "Where's Bella?" is a reference to the Bella Goth's disappearance in The Sims 2, as well as Martin Handford's Where's Wally? books.
 * "Murder in Pleasantview", by Alexander Goth. Possibly a reference to Bella's disappearance in The Sims 2. It's also interesting because Sunset Valley in The Sims 3 occurs before The Sims 2, while Bella is a child, and Alexander shouldn't have been born. Given that, it may have been a subtle hint to the time machine in The Sims 3: Ambitions, which can bring back books from the past or future.

 * When children or teens have a school trip to the graveyard mausoleum, they may receive a painting. The painting has a figure of a ghost with a green color and what appears to be a black coloration in his stomach just to the left of the mausoleum. It is speculated that this reveals a new type of death in an upcoming expansion pack, and that it is most likely a ghost Sim who died of illness as featured in The Sims 2.

 * "The Detention Hall" movie poster available in Buy Mode is based on the poster for the 1985 movie The Breakfast Club.

 * In The Sims 3: Pets, there is a painting referencing Jurassic Park.

Objects

 * The Access Aperture Door (available after purchasing Lunar Lakes), could possibly be a nod towards Valve's Aperture Science Facility shown in both Portal games, yet the word is also used to describe an opening which allows light to enter; possibly meaning a fancier word for door.
 * The Lucky Door is said to be made by Mr. McMann from Pleasantview after he won in Bingo seven days in a row.

Its description is "There's an entrance that knows, if you're wealthy with gold, then you're buying an Archway to Heaven". This is a reference to the first few lines of "Stairway to Heaven"; "There's a lady who's sure/All that glitters is gold/And she's buying a Stairway to Heaven".
 * There is an archway that is a direct reference to "No Surprises" by Radiohead. It comes with the base game and is called the "No Surprises Please, Archway" Its description is "Doors are scary, so you need to know what's behind them.

The Red Faction reference is slightly odd, considering EA had nothing to do with the game; it is published by THQ and designed by Volition.
 * When receiving a certificate for mastering Athleticism, the athletic institute is named "Grodiek Institute", a pun on a creator of the game, G. Rodiek.
 * While it may be just a name, Morrigan Hemlock may also be a reference to Dragon Age: Origins.

 * The background music used in the elevator from Late Night is the theme song from The Sims.
 * There are a number of hidden chambers in tombs in World Adventures. It has a shape of pentagon and an "R" symbol on the floor. It's an initial of Ray Mazza, who designed the tombs.

Homages to art, film, and literature

 * Attack with The Claw is an action available to Sims interacting with toddlers (as of Generations). This is a reference to the Jim Carrey movie "Liar, Liar".

 * It should be noted, that Game of Thrones (without the "A") is the title of the TV series made from the novels A Game of Thrones, premiering 2 years after the release of The Sims 3. In addition, the genre isn't fantasy like the original, and there's no connection between the names of the authors, being Guy le France in the game.
 * Also, the allusion wasn't carried over into the translations of the game, at least the Dutch and the German one.
 * Dragon Valley and the Baby Dragons seems to be inspired by Game of Thrones.
 * A downloadable item in the Sims 3 Store has a cube-shaped table lamp called "The Comrade Cube".

There is an option to 'direct them to the judgement area,' which parallels the threat of execution the characters face in the movie.
