Graduating class breaks into Taylor Swift flash mob

Yes, it seems nearly every 2015 high school or college graduation contains a speech or moment that makes the Internet rounds, and a Taylor Swift flash mob from Portsmouth High School in New Hampshire is the latest example. 

Last Friday, valedictorian Colin Yost (not to be confused with Colin Jost) concluded his speech with four words every senior needed to hear: “just shake it off.” Then, Yost led some 200-plus students in a choreographed performance of Swift’s hit “Shake It Off,” which is no small feat.
