Watch: Student turns his graduation speech into a Taylor Swift flashmob

She's everywhere, that Taylor Swift one.

A recent graduation ceremony at Portsmouth, New Hampshire went from a pretty staid speech about friendship and the road ahead into a full-blown rendition of Taylor Swift's Shake It Off.

Colin Yost, the graduation's valedictorian, managed to rope over 200 of his fellow students into participating in the flashmob which caught parents and guests by surprise.

Hey, it's better than hearing Green Day's Time Of Your Life for the millionth time, right?
