He may have been the best standup of all time. The guy burned off his own face while freebasing, and lived not just to tell about it, but to tell jokes about it. From him, I learned the words "motherfucker" and "honky," for which I'll always be grateful. It's impossible to be sad when remembering Richard Pryor. He'd been in pain and barely able to function for years, and while I'm sorry he's gone, I'm happy that he's free.
He was also committed to animal rights and environmental causes. Click here to make a donation to Pryor's Planet, the foundation Richard created to support animal shelters and rescues worldwide.
