Mr Pickles

A man in a cowboy hat stands beside a blue pickup truck in a wooded area, then opens the driver's side door. A black and white dog runs toward him, and as he turns, a stream of blood erupts from his back, spraying the truck and the dog. The man collapses to the ground, and the dog stands over him, looking up. The scene ends with a close-up of a graffiti-covered wall.
