Craig Ferguson got off to a decent start as the new host of CBS's Late Late Show Monday, improving on the show's season-to-date average by 21 percent in viewers and 14 percent in adults 18-49. Meanwhile, one of the finalists for the Late Late gig, former Ed star Michael Ian Black, has landed his own gig at Comedy Central. The cabler has tapped Black, Michael Showalter and David Wain to turn their popular stage show about a trio of modern-day Marx Brothers into a half-hour series.
