The hidden Easter eggs.

Tesla cars can play a menu of fart sounds through the speakers, routed to a chosen seat or even the turn signals.

Every Tesla ships with a hidden Toybox of Easter eggs that you reach by tapping the logo on the center screen and waiting.

Tesla baked playable classic Atari titles into its cars as Easter eggs, letting owners game on the dashboard screen while parked.

Tesla added customizable horn and movement sounds that the car can broadcast to the outside world, with coconut clip-clops among the options as a.

Moth Mode is a tongue-in-cheek dim-display setting that dramatically lowers screen brightness for dark drives, framed as a friendly nod to nocturnal.

Teslas can run a choreographed show in which headlights, taillights, windows, charge port, and falcon-wing doors dance in time to music.

Among Tesla's hidden voice commands, saying "open butthole" pops open the rear charge-port flap, a deadpan joke baked into the software.

For the debut Falcon Heavy, Elon Musk flew his own midnight-cherry Tesla Roadster as the test payload, with a mannequin in a real SpaceX spacesuit.

The Roadster's dashboard screen was programmed to show the phrase "Don't Panic!", a nod to Douglas Adams' The Hitchhiker's Guide to the Galaxy.

The Roadster carried a plate reading "Made on Earth by Humans," a quiet reminder of the car's terrestrial origins as it heads outward into the solar.

As Starman cruised away from Earth, the Roadster's sound system was set to play David Bowie's "Space Oddity" on a loop.

A miniature die-cast Roadster carrying a tiny Starman figure rode along inside the full-size car, a toy-within-the-payload flourish.

The Roadster carries an "Arch," a durable quartz data disc etched with digital copies of Isaac Asimov's Foundation trilogy, designed to survive in.

A small plaque on the payload adapter was engraved to honor the roughly 6,000 SpaceX employees who worked on the project at the time of the flight.

SpaceX's first capsule to reach orbit and return carried a secret payload that turned out to be a wheel of cheese, a tribute to a Monty Python sketch.
