DECATUR, Ark.- - It's clear the weekend weather took a toll on the state, but as Taylor Swift famously said, "shake it off."Check out this video of a Decatur Fire Fighter showing off his "kung-fu style." The video is courtesy of Northwest Arkansas's bravest and the has been viewed nearly four-million times. We caught up with the man in the video, Derek Knight, who says he was getting tired and delirious, so he wanted to lighten the mood. "We'd been up for quite some time. It was getting a little weary. I was a little tired and I was a little loopy from being so tired but they started putting music on the PA system on the truck and I started dancing," said Knight. The video is getting traction all around the world. Knight said if it helps people find a reason to smile in all the storms and damage, then he has done his job.
