Will Smith and Jimmy Fallon Beatbox and Record a Rap Song

Jimmy Fallon brought The Tonight Show to Los Angeles this week, so that means he's been getting a glut of celebrity guests (even more than usual). Will Smith stopped by, and the two of them used an iPad app called Loopy to beatbox and lay down some layered vocal tracks so they could rap over the top of them. Smith eventually leads the crowd in a call and response, and if you're in need of a little pick-me-up before the weekend, Fallon's goofiness is sure to put a smile on your face.
