Watch Pitch Perfect's Skylar Astin Totally Nail "Mr. Roboto" on Glee

Pitch Perfect star Skylar Astin makes an awesome guest appearance on this week's Glee as the leader of Throat Explosion, a rival glee club. He plays kind of a jerk who challenges the glee club at Nationals, but he does give one heck of a performance of "Mr. Roboto" by Styx and "Counting Stars" by OneRepublic. Seriously, he's so talented, it's completely ridiculous, kind of like the name "Throat Explosion."
