Out of the hosts that everyone knows I'd have to say Conan. I have tickets to see the show in November and it seems like it can end up being an awesome night. Out of everything that can be remotely considered a talk show I'd have to say, no questions asked, Stephen Colbert. The mocking, sardonic tone his character was developed upon is just hilarious, even if it's not strictly a talk show. Edit: I screwed up the poll somehow.
