I remember that episode. It was disgusting. It was the last episode of Mork & Mindy that I watched, and it began my contempt for Robin Williams in particular and television programming in general.
It’s almost enough to make a fella kill himself!
When looking back at Robin’s movies, I began reading Roger Ebert’s reviews of some. Even though I (and many others here as well) can certainly disagree greatly with the political views expressed by Roger in some of his movie reviews and elsewhere, he was dead on in his strong critiques some of Williams’ movies with seemingly the same theme over and over with the affable rebel fighting some reactionary, etc.
