You probably shouldn't watch this video if you're superstitious.
This is another product of my Doctor Who geekfest. One of the episodes has this classic horro movie moment when a guy (who is working on a space station that may or may not be in the process of being overtaken by the devil) starts hearing a voice in his head saying "don't look behind you."
This is what I do for fun. You wouldn't want to meet me in a dark alley.
