A bunch of college students were flying on Frontier Airlines from Colorado Springs to San Diego for an Ultimate Frisbee tournament. The asked the flight attendant if they could do a "Harlem Shake" video on the plane. They agreed and now there's a video on YouTube.

In what may have seemed like a fun-hating move, the Federal Aviation Administration is investigating the incident. They aren't so concerned that it happened. They just want to make sure it didn't happen during takeoff or landing.
