He also played some nasty SOB's in "Poltergeist", "Little House on the Prairie", and most memorably "The Jeffersons" wherein he portrayed a KKK official. I'll never forget the end of that episode. The character has a heart attack and collapses. George saves him by giving CPR. Later when he finds out he says, "You should have let me die". Shocking for the time and even by today's standards.
