Before Danny DeVito hit the stage of 'The Late Late Show' (weeknights, 12:37AM ET on CBS), he gave Craig Ferguson a list of topics he'd be forbidden to bring up. Obviously, by reading the list aloud, the host mentioned them all, and DeVito even elaborated on a couple (like wife Rhea Perlman getting her knee replaced).

DeVito also had a list of permitted subjects -- but only "horse meat" was on it. DeVito said he'd started a business selling the stuff, from his car.

Ferguson refused to promote DeVito's latest scheme on the show, especially since last time he was hawking a race horse. (Get it?) DeVito then approached the stage in a horse costume and danced with the host. Quite an odd entrance.
