Let's take a moment to wonder what was behind this video. What happened way back in 2012 when this video was taken that made that man think "shredding and karate, that'll be my thing." Maybe it was just a really bad day at the mill, afterwhich he came home to his doting wife who looked him up and down and said "honey, I know what you need" before handing him an electric guitar and setting some bricks on fire.
We just don't know.
