Mork & Mindy
Mork & Mindy was basically an excuse to let Robin Williams be Robin Williams in a sitcom format. Technically a spin-off from Happy Days (believe it or not, Mork originally landed in Milwaukee… and takes off again to land in Boulder, Colorado), Mork is a clueless but good-hearted alien who is sent to Earth in order to learn about humans. Then Mindy finds him and lets him live in her attic. (We never said this would make any sense….) The show ran from 1978 to 1982 on ABC; 39 episodes below.
