Filling in for Jimmy Kimmel Tuesday night, Dave Grohl did an amazing job as guest host of Jimmy Kimmel Live.

It was Halloween so Grohl came out dressed as David Letterman. His guest for the night was star of the upcoming film Bad Moms 2, Kristen Bell. Bell dressed as Tom Selleck’s Magnum P.I. character.

During their interview the Foo Fighters frontman mentioned his daughters were huge fans of the film Frozen and he would be the coolest dad ever if he jammed with Bell.

Watch Grohl and Bell perform a mashup of “Do You Want to Build a Snowman” and Metallica’s “Enter Sandman.”

Here is the full interview with Grohl and Bell.
