Robin Williams as Mork from Ork - Mork & Mindy TV show. I know he's not one of the movie stars who normally wins hottest man of the year, & maybe he's a weird crush, but I think he's handsome / cute, and I've always had a crush on him ever since Mork and Mindy.
I've been watching a lot of Mork and Mindy on the Hub channel...adored this show so much as a kid--the randomness, Robin Williams' bursts of brilliance, the 70s-chic sets, and Pam Dawber. I now realize that Pam Dawber is the closest thing to a personal style icon I can I.D. from that era. LOVE her!!
