Backfield in motion

So I went to the park today with my gigundo bar review book. After awhile, my mind started to wander and as I read the same sentence over and over again I became aware of a periodic ::thunk:: behind me. I turned around and saw an old man with a football. He would take the football in one hand, and after what looked like a baseball pitch wind-up he would chuck the ball through the branches of a nearby tree. The football would hit the ground with a ::thunk:: a dozen yards or so from the old man and he would slowly walk to retreive it. Then he would throw the ball into the tree again from the other side.

As crazy as it sounds, it looked like fun.
