Portsmouth High School's class of 2015 made the most of their graduation ceremony with an electrifying flash mob.

The seniors went with Taylor Swift's 'Shark it Off' as their song of choice.

The fun started when veledictorian Colin Yost reminded the staff and students that "all you have to do, is shake it off." And from there it was a party scene!
