We all know who the 'final four' are in this contest but CBS wants the contest to go on a little longer. When Craig Kilborn announced earlier this year that he was leaving 'The Late Late Show', CBS began an extensive search to replace him. Four finalists emerged, actors Craig Ferguson and Michael Ian Black, MTV's Damien Fahey and comedian D.L. Hughley have all been asked by CBS to return for one week tryouts.

The order will be Ferguson, Hughley, Fahey and then Black. Fahey will be at a slight disadvantage since he drew Thanksgiving week and will only get to host three shows.

A CBS spokesman said a final decision will be made in about one month. Kilborn surprised CBS executives when he announced he was leaving the show after five successful years on the air. All four of the finalists have been guest hosts at various times but only one will get a full time gig on CBS.
