Off with the gloves and onto the stage go funny men and women armed with their best barbs and looking for a comedy knockout. TruTV's half-hour competition series features three comics in each episode battling in fast-paced challenges, with points awarded based on positive crowd reactions. One-upmanship is the goal as competitors attempt to land massive comedy blows and whip the crowd into a frenzy of raucous laughter. A final round decides the champion, and the least-funny participant is ultimately forced to face the crowd and apologize. Comic Damien Lemon hosts.

Writer/comedian Guy Branum ("The Mindy Project," "Chelsea Lately") brings his popular live comic show to TV in a mashup of two of the medium's best-known formats. Branum serves as host and master of ceremonies on the half-hour series, an uproarious combination of a game show sprinkled with talk-show elements. In each episode, celebrity guests come to play, not plug, in various challenges on the only talk show that literally counts. Emmy Award-winning writer Karen Kilgariff and author and journalist Casey Schreiner serve as judges, who roast the contestants and award or deduct points from them based on criteria such as telling an anecdote, flirting with the host, name dropping, being underdressed, excessive agreement, and making the audience go "awwww."

Broadway, television and film star James Corden takes over the reins of the late-late-night franchise at CBS from fellow U.K. import Craig Ferguson. The British performer -- whose previous hosting gigs include five years of The Brit Awards -- puts his charm, warmth and creative instincts to use as he interviews celebrities and newsmakers, and hosts musical performances in his post-"Late Show" time slot.
