This week on The Muppets, Foo Fighters’ Dave Grohl battles Electric Mayhem’s Animal in an epic drum-off that will surely leave you wanting more epic drum-off-ing. Grohl begins the battle by saying, “I’ve been waiting years for this Animal.” His archnemesis Animal responds, “Now we see who best.” Watch the video to find out who best! Wow. A drum battle. I remember when Animal was just a little (Muppet) baby. If Nanny’s ankles could see him now.
