Miley Cyrus Crashing a '50s Dance Is the Funniest Part of SNL's Premiere

You know that scene in Back to the Future when Marty McFly (Michael J. Fox) shocks all the kids at the dance with some rock and roll from the future? Imagine that scene, except with Miley Cyrus rapping and twerking, and you've got one of the funniest sketches from Saturday Night Live's season premiere. We knew from Cyrus's promos that the host would provide plenty of scandalous moments, but this is actually hilarious. Take a look to see new cast member Jon Rudnitsky acting terrified of Cyrus's proposition.
