Plot: The halls were decked with celebrity “cameos” as real-life musical guest Michael Bublé took his current chart-topping Christmas album to the next level by featuring some special guests. But the crooner just couldn’t seem to get his sidekicks in line, whether it was a scat-happy Sting, a smitten Taylor Swift, or Russell Brand, who doesn’t actually sing a word. Fallon got to pull out his celebrity impersonations, and Bublé was able to show a little acting prowess.
Best Line: “Now why would an angel want to get high? They wouldn’t need to, would they? They’re already in the clouds, it’s kind of their thing.”
