Although comedian Marc Maron tweeted about the news, he gave a more poignant and in-depth statement via his podcast, WTF With Marc Maron. Marc spoke with Robin in April 2010, but he released the conversation with a new intro just yesterday.
In said intro, he said, "Robin Williams was really one of the greatest comedians ever, ever, ever. In the history of the world, as far as I know it. Because he had all the things that [were] necessary to be a great comedic artist. He was sensitive, he was perceptive, he was empathic, his mental agility was astounding. He was full of love . . . And we felt it. And there was a humanity to Robin Williams. Robin Williams changed everything. There's nobody that wasn't touched by Robin Williams at some point. He was the king."
