Conan O'Brien: A Celebration

In 1993, a redheaded newbie named Conan O'Brien got a shot at his own show, taking the 12:37 a.m. slot on NBC — and he's been a late-night staple ever since. All right, he did take one break recently, following the debacle around The Tonight Show... but now, with his return to TV on TBS' Conan, he's poised to reclaim his position as one of the brainiest (hey, he went to Harvard) yet silliest people ever to get his own show.
