'Mork And Mindy' was an American SF-based sitcom produced during 1978 - 1982. Unusually it was a spin-off from an non-SF show - the 50's nostalgia sitcom 'Happy Days'. So successful was the episode, which featured Robin Williams as an alien called Mork from planet Ork (sic), that a spin-off series followed within the year. Pam Dawber was cast as Mindy McConnell and the show reset in the present day. Although clearly just a vehicle for Williams' manic comedy, the show was an international success, and even allowed for some social commentary between the laughter.
