Dog gone mad

Mad dog has finally gone mad. I come through the kitchen door and the dog runs and skids across the wooden floor boards towards me. Some how he does a flip in the air and lands with his back on the floor. He lyes there for a few seconds, both of us still trying to work out what just happened. Then he scrambles onto to his four paws and starts walking in the other direction, with his head held high trying to pretend that nothing happened. As it is my dog sees himself as the top dog in our family therefore always walking round with a proud look on his face. Here is a video were if my dog plus a couple more were let on a beach this is what it would look like.
