He Rudely Pulls This Lady's Dress Up. When I Found Out Why? I Couldn't Stop Smiling!

I am not going to lie to you, when I first started watching this video I was like what in the world is this. As the video went on I became more and more confused at what was playing on the screen. Why was this guy so mean? Why did he lift up dresses and throw sand at people? He must know that is an inappropriate thing to do, right? He claims otherwise but when we get to the end? It all came together, fantastic video.
