I think he was probably ashamed of not being able to conquer his addiction and couldn't go on making jokes about it anymore. I think it was his way of saying it's not really a joking matter for people struggling with it.....His last statement.
there is no universal comic or actor for everyone but robin came close. i think we all came across some role/show/standup/appearance/cameo that he did
that made us smile, laugh, shed a tear or take notice. never came across another comedian that could relate or improv a string of jokes/consciousness
and shift gears up and down as effortlessly as he.
Absolute Genius, Absolute Classic !!! Mrs. Doubtfire, Birdcage, Good Will Hunting, Dead Poets... the list goes on.... It is sad that sometimes, those with such incredible talent also suffer from incredible Demons. Words are not enough.............. Robin, R.I.P.
