Jimmy Fallon hosts the Christmas show, playing an adult trying to crash a dance at his old high school, a retired Regis dropping in on Hoda and Kathy Lee, Russell Brand and then Justin Bieber singing Christmas duets with Michael Bublé, getting advice from his mirror image as he prepares to host SNL, the reluctantly-dancing host at a 1928 Manhattan cocktail party, the keyboardist in a quartet of SNL alums ("I Wish It Was Christmas Today"), and the horse on Broadway's "War Horse." Jude Law impersonates Justin Timberlake on "Weekend Update," Michael Bublé sings, Tommy Palmese does his off-Broadway show, and Jesus visits Tim Tebow and the Broncos in the locker room. Written by
