Have to admit, whenever I see the title of this thread come up, I think back to a video George Sodini did:
George Sodini Home Video - Pittsburgh Gym Shooter - YouTube
It was pretty creepy finding the original up on YouTube shortly after the shooting. This isn't it, but does contain the full original inside it. From other news outlets, I guess the guy hadn't had sex in 19 years and was a little fixated on that. In the end, he was a very unhappy, angry person.
