While I was never a great fan of his comedy (tho he did do a very funny sketch with Chevy Chase on SNL, a word association bit), I am very sad to see him go. I saw some news item about him, maybe a year ago, which disturbed me, seeing him so completely immobilized, and realizing that it was multiple sclerosis. Seeing such a graphic reminder of the worst this disease has to offer was frightening.
His daughter Rain, (cool name) has been a spokeswoman for MS awareness, and I hope she keeps at it.
Anyway, I am sad to see him go.
