Laughter. There's just something absurd about sticking the butt plate of your armor into the face of a corpse. Here's an IRL equivalent... Truck driver is tooling down I-5. A raccoon wanders out into the road. Truck rolls over raccoon, kills it instantly. Truck driver gets out of truck and goes over to raccoon. Truck driver squats-stands-squats-stands-squats-stands. Everyone watching thinks truck driver is a total idiot and laughs at him.
