Some stupid fool sees a bull roaming the streets. Remembering the "reward for capture of runaway bull" sign that he had seen in a local shop earlier that afternoon, he gritted his teeth and got ready to lasso the wayward bull with his bare hands. Unfortunately for him he didn't consider that he is a total pussy in comparison to a wily bull, and the hill knocked him the fuck out. Perhaps even ended his miserable life, but that's purely speculation.
