Justin Timberlake amazes me. When you think of all the teenyboppers that began in the business who were unable to prolong their success after their bubble-gum-genre crashed and burned, it’s extremely impressive how much he reinvented his career. He’s not only managed to land major acting roles, but he’s also had continued comedic success on Saturday Night Live with some incredible sketches (who could forget “dick-in-a-box?). So when he joined Jimmy Fallon for the History of Rap Part 2, I almost fell off my chair. It’s damn good, and they even topped the last one. I need not even mention Jimmy Fallon’s talent for impersonations. That guy never disappoints.
