Genre: Sitcom, Fantasy
Premise: Mork, an alien from the planet Ork on a mission to Earth to study human behavior, travels to 1970s Boulder, Colo., where he meets up with Mindy, a young journalism graduate, after his egg-shaped spacecraft lands there. The bumbling alien is trying to get a handle on Earth culture, and his frequent dispatches back to his home planet give him the opportunity to sound off on human foibles. This spinoff of ``Happy Days'' features Robin Williams as Mork in an early starring role for the comic actor. As Mork would say, ``Na-nu, na-nu!''
