Mork and Mindy was a spin-off of the 1974 series "Happy Days". In episode #110 titled "My Favorite Orkan", Mork was sent to Earth to kidnap Ritchie Cunningham and take him back to Ork. The character, Mork, was so popular that Robin Williams had his own series starting the very next season!

Mork was from the Planet Ork, and he was sent to Earth in his eggshell spacecraft to observe our culture and study our emotions, since Orkans don't have any. He meets Mindy McConnell and she lets him stay in her attic. Mindy tries to keep the fact that her roommate is an alien a secret. However, her Dad is not too happy about the fact that his little girl is living with a guy, so Mindy has to explain to her father mork's true identity! Everyone else thinks that Mork is just some guy who's one step away from a mental institution.

At the end of each show, Mork would have to file a report with the Orkan leader named Orson. After making the report, he would twist his ears and say "Nanoo, Nanoo" which is Orkan for "Goodbye".

Also, Mork and Mindy both appeared on the pilot episode of another Happy Days spin-off called "Out of the Blue". Mork visits his old friend "Random" (An Angel). During the series it's revealed that Ork and Heaven are near each other! "Out of the Blue" only lasted four months.
