Late night talk shows are a huge source of comedy. The hosts all have a background in comedy, the writers are all primarily comedy writers, there are comedy guests, stand up performances, comedy sketches, and of course the monologues. This was a huge year for late night, with legendary hosts leaving, new hosts coming on board, and all kinds of shake ups in lineups. With the tenor of late night programming shifting uncomfortably to bar games, it's important to celebrate the greatness, and there was plenty. There were last epic last nights, creative first nights, and some great moments in between. We picked our top ten.
