Watch Carrie Underwood and James Corden Do Carpool Karaoke and Recreate the ‘Most Annoying Sound in the World,’ From Dumb and Dumber


Painfully eventful, wonderful karaoke session: The duo shows off their virtuosic technique for hitting the "most annoying sound in the world," Carrie talks about that thing Mike Fisher did to Kevin Bieksa last month, and James "Hoss" Corden gets stuck in some boots. Ouch, all around.
