George Carlin

We saw George Carlin a few years ago.  It was after his first heart attack.  He was very angry in his later years.  If you listen to his earlier stuff, he was happy and his voice was not so tight.
 Maybe because he no longer used drugs or alcohol.  But he had a distinct edge about him in his later comedy routines.  I see the same thing happening to Robin Williams.  He's getting angry and has lost the playfulness to his comedy.  Again, maybe it is because he is off the drugs/alcohol too.  He also had a heart attack or some heart problems.    

His thoughts about hell:  " I'm not concerned about all hell breaking loose,but that a PART of hell will break loose... it'll be much harder to detect."
