Entire High School Lip Dubs Katy Perry's 'Roar' In Just One Take (VIDEO)

So this is impressive.

The students and staff of Lakewood High School in Colorado got together to film a lip-synched version of Katy Perry's hit 'Roar' (well, the school mascot is a tiger called Growly). And not only did they choreograph it wonderfully, it was all done in one take. And it involved over 2,000 students.

From the jocks to the debate team, gymnasts to frisbee-throwers, it's an amazing, uplifting feat (and a fascinating, brief insight into American high schools).

Bravo, director/producer Courtney Coddington.
