Look. Back in the late 70's/ very early 80s when Mork and Mindy was a smash hit it seemed like Robin Williams was comically excellent as Mork. He did do very well. But there was a catch. Mork was being written of a lot and the character was getting many funny things to say that actor Williams never actually said. Look at a Cracked Magazine CE 35 ( CE being Collector's Edition). Find it at Internetarchive website. There is a bunch of letters to Mork ( actually they seem to be fake letters written by magazine writers). It seems like Robin Williams as Mork is answering these "letters" but he actually is doing nothing of the sort. The mag writers are!
