Dave Grohl of Foo Fighters hosted last night’s episode of “Jimmy Kimmel Live.” He stepped in for Kimmel, who is taking time off this week. Because it was Halloween, Grohl dressed up as David Letterman (with the full beard and everything). After a monologue and a segment about Halloween costumes, he was joined by Kristen Bell for a chat and performance of a Frozen/Metallica mash-up. Later, he chatted with Alice Cooper. Foo Fighters backed him up for a rendition of his song “Ballad of Dwight Fry.” (The performance ended with a fake beheading.) Watch clips from the episode below. (MORE HERE)
