Jimmy Kimmel is taking this week off of his show to be with his infant son (who needs surgery) so he is having guest hosts all week long. Last night Dave Grohl filled in. It being Halloween, he did it dressed as David Letterman. You can hardly recognize him! Kristen Bell and Alice Cooper were the guests. There were musical collaborations including a Metallica/Frozen mash-up. Check out the video!
