Stephenson looks like just an obscure fun guy in the video, but according to his Web site and bio, he's had quite a career. His illness made people think he would die not long after birth, but he's still going strong. He's held various jobs as a political aide for various high ranking people in Washington and works as an inspirational speaker, 'natch.
