Invite an Alien to Live with You Day – July 21, 2025

Invite An Alien To Live With You Day is celebrated every year on July 21, to remember the four-year-long Pam Dawber and Robin Williams show “Mork & Mindy.” The show is about an alien from the planet Ork named Mork, played by Williams, on a mission to Earth to study human behavior. Mork travels to 1970s Boulder, Colorado after his egg-shaped spacecraft lands there. Here, he meets up with Mindy, played by Dawber, who is a young journalism graduate who lets him live in her house.

The episodes revolve around Williams’ hilarious portrayal of a bumbling alien trying to get a handle on Earth culture along with his frequent dispatches back to his home planet.

History of Invite an Alien to Live with You Day

“Mork & Mindy” is an American television sitcom whose first episode aired on A.B.C. on September 14, 1978. It was created as a spin-off show following a highly successful episode of the comedy show “Happy Days.”

Mork first appears in the season five episode “My Favorite Orkan” of “Happy Days” in February 1978 and is a take on the 1960s sitcom “My Favorite Martian.” This was around the time when “Star Wars” had been released and the show wanted to feature a spaceman to capitalize on the popularity of the film which was — and still is — all the rage.

Williams’ character, Mork attempts to take Richie Cunningham back to his home planet Ork as a specimen but is foiled by Fonzie. In the first broadcast it turned out to be a dream of Richie’s, but when Mork proved so popular, the version was later re-edited to show Mork performing a classic memory wipeout and erasing the experience from everyone’s minds.

The character of Mork was played by the then-unknown Williams who garnered praise and attention for his portrayal of the alien. The now-iconic actor immediately impressed producers and viewers with his undeniable comedic ability.

According to a popular anecdote, when Williams was asked to take a seat at the audition, he sat on his head and producer Garry Marshall cast him on the spot. Marshall later commented that Williams was the only alien who auditioned.

Storylines are usually centered around Mork’s attempts to understand human behavior and American culture, while Mindy helps him adjust to life on Earth.
