Too funny.  Dave Grohl sat in for Jimmy Kimmel last night.  for Halloween he dressed up as a very convincing David Letterman.  Now besides being on of our favorite rockers Dave is also a dad of 3 little girls.  That said you can imagine his thrill to have Kristen Bell as his guest.

Dave said that having Kristen there with him was the biggest thing to his girls, Violet, Harper and Fifi.  She starts with Snowman which Dave says is his Highway to Hell.

They mash it with Metallica's Enter the Sandman.  Brilliant.
