From ''Mork and Mindy'' to Oscar nominations, remembering the late actor-comedian's best
Robin Williams was an unknown stand-up comedian when Garry Marshall cast him as the alien manchild from Planet Ork on an episode of Happy Days, a guest spot that quickly transformed into a spin-off (not to mention a 1979 Golden Globe win and Emmy nomination). It's the first great demonstration of Williams' utterly unique blend of childlike enthusiasm and aggressive absurditynot to mention his gift for spouting a Zeitgeist-defining catchphrase. Na-Nu Na-Nu!
