Jack Black stopped by “The Tonight Show Starring Jimmy Fallon” to chat with the Emmy-winning talk show host about his upcoming Universal Pictures film “The House with a Clock in Its Walls.” Fallon gave a shout out to Black’s Grammy-winning band Tenacious D, who has a new album dropping and upcoming tour dates, starting next month.

Fallon surprised Black by bringing out one of the actor and singer's favorite toy instruments, the Sax-A-Boom, which he notably helped make popular during past Tenacious D shows. Fallon asked him if he could play it, and in true "School of Rock" fashion, he happily obliged and delivered an epic performance, while The Roots joined in.
