Over the past few months, Jimmy Fallon has turned into the king of viral videos, putting his guests on "The Tonight Show" up to a series of hilarious sketches that have featured some of the biggest stars in entertainment, from the cast of "Saved by the Bell" to "House of Cards" star Kevin Spacey, plus Jeremy Renner and his fellow Avenger Scarlett Johansson.

Now it's the turn for two of the funniest men in show business, as Jimmy Fallon and Jack Black join forces to sing a frame-by-frame version of Extreme's video of "More Than Words" - a version so fantastic that the band's guitarist, Nuno Bettencout, told Rolling Stone Magazine had "brought tears" to his eyes!

Watch the amazing Jimmy Fallon and Jack Black version of "More Than Words" below.
