Your most inspiring/touching Robin Williams moment?

It's been awhile I know, but it was a little to painful to talk about it before. Robin Williams was a great comedian and actor, many of the life-changing moments that I've had have been accompanied by one of his movies, be it bicentennial man, dead poets society or even Aladdin. My question is this, which moment in Robin Williams career did you find most touching or inspiring. Both if you've got them. Most touching would be at the end of Bicentennial man, where he is finally given Human "status" Most inspirational was in What Dreams May Come when Christopher (Robin Williams) gives up his chance of eternal paradise to be with his wife. Plenty more but those have to be most inspiring and most touching.
