The Roots are featured heavily throughout the show, providing the bumper music in and out of commercials, as well as the opening song "Here I Come" and playing the show off the air. Fallon frequently interacts with the band during the course of the show, and they occasionally provide snippets of music for some monologue running jokes such as Funkin' GoNuts. They also provide music and drum rolls for the games with show guests, along with theme songs for the games and segments like Darts of Insanity, Wheel of Carpet Samples, and Christmas Sweaters.
