The Chattanooga firefighters know a thing or two about "Stayin' Alive" – both when it comes to saving actual lives and regarding the Bee Gees. In a June 29, 2013 video from the city's fire department, a group of firefighters perform an epic "flash mob" to the famous disco anthem. (It's pretty darn hilarious watching them getting super groovy in full uniform.)

However, this video serves a bigger purpose than pure entertainment: the Chattanooga Fire Department uses their dance moves to illustrate the importance of CPR, both through a skit as well as a scrolling message at the end detailing CPR instructions.

According to WRCB, this video is a tradition for every graduating class of Chattanooga firefighters, and this particular video sums up "their experiences during the six and half months in the fire academy."
