From a promotional postcard for their hit sitcom Mork & Mindy, Robin Williams and Pam Dawber pose on bikes — Williams, an avid cyclist during his lifetime, sits on his backwards. Mork & Mindy ran from 1978 to 1982 on ABC. Williams played an alien from the planet Ork who moves in with Dawber’s Mindy McConnell, an aspiring journalist living in Boulder, Colorado. Cultural confusion and extraterrestrial one-liners ensue. Na-nu na-nu.
