I'm saddened to hear the news about his passing.  In my experience I believe that comedians get into the field due to an aspect of the desire to help people and give them a few laughs.  Don't think I recall his comedy acts but reading through the tributes I get the sense that people liked him alright and that he was a good guy.  His tagline is great - "that's not right."  As if he internalized a solid sense of right and wrong.  So I didn't know his work but I think I like him.
