Na-Nu Na-Nu. After an appearance on "Happy Days," Robin Williams brought his wild antics as the quirky, misfit alien Mork to this popular 1978-82 sitcom. Sent to Earth from the planet Ork to study human behavior, Mork lands his egg-like spaceship in Colorado where he befriends--and later falls in love with--Mindy McConnell (Pam Dawber). With Conrad Janis, Elizabeth Kerr, and, in the fourth season, Jonathan Winters as Mearth.
