35 year old Derek Klingenberg, a farmer in Kansas has a video showing how he brings the cows home. He can literally bring his cows in from the field by playing the trombone. In the video, he's all alone playing the 'Lorde' song Royals. First off the guy can play a trombone, secondly - it works!

How does it work? Cows are very curious animals and they know that if they do come, they will get a treat. Some molasses. Hell, I'd come too!
