I saw him on Comedy Central's Beth Littleford Special (remember her? She was the Daily Show co-host who would do "Barbara Walters"-style celebrity interviews complete with frosted lenses, pastel overload, and lots and lots of flowers in the background) several years back and he was such an embittered, humorless ass, I've sort of been put off by him ever since.
"Impossible is just a big word thrown around by small men who find it easier to live in the world they've been given than to explore the power they have to change it. Impossible is not a fact. It's an opinion. Impossible is not a declaration. It's a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.”
