brain damage

A man in a white shirt stands at his office cubicle, then repeatedly swings a long, thin object, possibly a ruler or stick, in a wide arc above his head. He brings the object down in a striking motion toward his desk, then raises it again, repeating the swing. Other office workers are visible in adjacent cubicles, some looking toward him. The scene takes place in a brightly lit office with green walls and white cubicle dividers.
