He yam what he yam
He was one of the first comedians I actively recognized and sought out. I've still got my CD of 'Live at the Met'. In 1995 I had the good fortune to be at an event where he was on one of the panels. I couldn't tell you now who else was on the panel with him, or what the subject was. But I will never forget Robin Williams pretty much taking over the stage and going into an off the cuff Jacques Cousteau riff about Dale Chihuly's sea anemone-like glasswork. He was as manic and non-stop in person as he ever was on film. Afterwards I had the chance to shake his hand and tell him how much I loved his comedy. It's still a personal highlight.
He was one of us. A gamer and a fan. He famously named his daughter Zelda after The Legend of Zelda. He read Isaac Asimov's Foundation and Warren Ellis' Transmetropolitan. He played Dungeons & Dragons and World of Warcraft (apparently he was the Prince of Trolls in Mannoroth trade chat. I can only imagine). And now he's gone. Taken from us by the darkness in his mind. He will be missed.
