Nerd Stampede!

Not that the injuries were all that weird, but the people and circumstances surrounding it were. There was a stampede at a local comic book convention and the victims were trucked in still in costume. There was a hobbit that got beat down by an ogre of a man, a Dr. Who fan with his ear ripped off and no feeling in his lower body, and a zombie nurse with fake lacerations that fooled Richard at first.
