Another commencement, another flash mob.

The seniors at Portsmouth High School in New Hampshire broke out into a synchronized dance routine during their graduation ceremony, because I guess that's what you have to do to get your diploma nowadays.

This particular routine does have a good hook, emerging out of valedictorian Colin Yost's speech. Yost closed by saying, "All you have to do is shake it off," before kicking off the Taylor Swift dance. Apparently, he planned the whole thing, organized his 230 classmates, and emailed a secret instructional video so they could learn the moves. This kid is going to kill freshman year of college.
