Thanks, George.

Via Harry Shearer, who has this to say:

I marveled at the quality that I've come to admire more than most others in this business: his persistence. George seemed to love what he did, and so he kept doing it at a very high level...

George grew tougher and sharper over the years, putting more of himself, and his intellect, at the service of his always nimble, always adventurous comedy mind. And, while his comedy was dark, his spirit with his peers was generous.
