There's just a week and change to go before Conan O'Brien's new show, Conan, debuts on TBS and O'Brien has been talking up the show through some hilarious TV ads, a 24-hour Conan cam and by answering fan questions through Twitter, Facebook and YouTube. In the seventh edition of "Conan Takes Your Questions", he unveiled his costume for this Halloween. Who's he going as? Conan O'Brien, of course.
