Ishn't that weird?

I laugh at things like that one scene in the movie Silent Hill when Pyramid Head grabs Anna on the steps of the church and first rips her clothes off, then rips her skin off, rips her bloody corpse in half and chucks it at the door of the church. It's not really a nervous laughter. Not really a funny laughter, but more of a disbelief of something so extreme that it's unreal.
