Mork & Mindy was a sitcom about Mork (Robin Williams), an alien from the planet Ork, who lived with his friend Mindy (Pam Dawber) in Boulder, Colorado. The series ran on ABC from 1978 to 1982. The show was a spin-off of the fifth-season Happy Days episode "My Favorite Orkan," which was a showcase for guest star Williams but presented the character Mork as part of Richie Cunningham's dream.
