The video was posted Monday by Funny or Die. It’s a remarkable, comedic imitation of Crosby and Bowie’s beloved 1977 Christmas special in which they sang “Peace on Earth/The Little Drummer Boy.” In it, Ferrell plays Bowie and Reilly performs as Crosby.

The mimicry is impressive, with almost every line exactly repeated. Reilly fittingly dons a V-neck sweater, and Ferrell sports Bowie’s blue blazer and a British accent. The two stay faithfully in character until the end, when they curse at each other and Ferrell knocks over a Christmas tree.

The video had gotten 135,000 hits by Monday night.
