In this promo for Jimmy Fallon's Saturday Night Live hosting gig this weekend, the former SNL star is doing his best to decorate the upcoming episode with some holiday flare. However, it doesn't help that he clearly doesn't have any idea how to sing (or play) one of the most iconic Christmas songs, "Jingle Bells." Plus, Fred Armisen is a little too worked up over his affirmation that Santa Claus is real to actually contribute anything to the video...which erupts into a minor tantrum.
Since leaving SNL in 2004, Fallon has returned in a handful of cameo appearances. However, this Saturday will mark his first time hosting the show. Fallon will be joined by singer Michael Bublé as a musical guest. Watch the episode this Saturday, Dec. 17 at 11:30 p.m. ET/PT on NBC.
