Dave Grohl hosted Jimmy Kimmel Live last night while Kimmel himself is absent due to his son's upcoming heart surgery. Yesterday being Halloween, Grohl dressed as Dave Letterman and that's not even the most outlandish bit from the shot. Grohl teamed up with Kristen Bell, who voiced Anna in the smash hit film Frozen, for a medley of Metallica's "Enter Sandman" and Frozen's "Do You Want To Build A Snowman."
Needless to say, it's amazing.
