The Roots have had a variety of special guests sit in over the course of their run with host Jimmy Fallon, but last night guest Larry Campbell got to participate in one of the more engaging segments as Fallon revived the “Freestylin’ with The Roots.”

The way it works is this–Fallon quizzes a member in the audience on a couple of random questions and The Roots respond with a freestyle jam based on that theme. Among those played last night were a made up holiday (National Rollercoaster Day) as well as audience member Jimmy, decked out in a “Fallon/Timberlake ’16” shirt, who is foolishly rooting for the Cleveland Cavaliers in Game 6 if the NBA Finals. Jimmy created a new slam dunk called The Triple Lindy of Back to School fame.
