It's an impossible shot. No one could throw those fragments with that much accuracy, all at once, even if they were looking. A human shoulder shouldn't even allow me to throw like that, behind me. Not the average human's shoulder, anyway. I know where every fragment lands to within a tenth of a centimeter.
Every spot is extremely painful and vulnerable without being a serious injury.
Like I said, I don't want that much attention. A story like this will just get dismissed as drunken fable, instead of calling in a death investigation. The way those guys howl and thrash around contrasts very asthetically with the absolute stillness of the other bar patrons. It's very important to make an art out of whatever you do best. Bartender, I seem to have broken my glass.
