In an episode of "Cheers" Woody tells Frasier he broke his thumb when he slipped on the ice. I noticed it still bandaged a few episodes later. Did actor Woody Harrelson himself break his thumb?

Woody Harrelson broke a bone in his arm when his car flipped in practice for last year's event--which explains one of the casts (the other was the result of a fist fight) he wore in last season's episodes of "Cheers."

Accidents, Unger acknowledged, do happen, "but we continue to pride ourselves on the amount of training/preparation of cars and celebrities." Once invited to compete, he said, all contestants must spend four days at the Drivers Connection, a high performance driving school at Willow Springs Raceway, near Rosamond.
