I didn't even know there was a "race" going on between them. However, I turned to Colbert Report and saw Conan, Jon, and Stephen all being crazy last night. It was pretty damn funny too. Colbert was hitting the desk with his belt and Stewart and O'Brian were hitting it with shoes. I wasn't sure why, all I knew was it was funny.
