That cow was pissed! I bet the reason the video ended was because the cow tore the camera man a new asshole!
As a kid, I had to help out on my grandparents ranch during summers. One year my job was to help vaccinate the cattle. I was stationed on a chute with a cattle prod, and I had to persuade cows to enter the cow clampy thingy where they got vaccinated, tagged and branded.
One particularly BIG cow was not interested in entering that chute so I hit him with the cattle prod, right at his arse hole. I didn't really understand the difference between a cow and a bull. That bull tore up the chute, jumped over the remaining fence into the area where the ranch hands were working, and almost killed my grandfather. He tore up a bunch of equipment, and put a big dent in the foremans truck.
I totally lied and said I didn't know why he went nuts........
