Stephen Colbert may be an award winning superstar, but when Oprah calls, you do the interview on her terms! Stephen shares his experience on Planet Oprah with Dave, leaving this viewer to conclude that once a diva, always a diva. Oprah is fairly stuck on herself too. Just kidding, as you well know, we love Stephen; and I thought Oprah had given herself a big going away party some time ago. Perhaps she does live on another plane of existence?
