Stephen Colbert becomes part of late-night network TV history this week when he takes David Letterman's old seat on The Late Show. It'll be a departure from his Comedy Central series The Colbert Report, in which he put on a different persona than his own, but The Late Show With Stephen Colbert will feature Colbert just being Colbert. If you watched his old series, then you knew him as an arrogant, right-wing nut who would slyly get a satirical point across with his masterful interviewing skills. But alas, we're all going to have say goodbye to that Stephen Colbert in favor of the real him. That's a good thing, because the real Colbert has been baring his real personality in recent months, but if you haven't seen the real Colbert, we're looking at the times Stephen Colbert was actually Colbert.
