Same thing happen couple years ago to a guy who played the character Gaston, at Disney World. Put a fireworks rocket on the top of his head. Used his head as a launch pad. When they called 911, they told them it was not necessary to rush to site since he was headless.
There used to be a photo on the net of someone who lit a
a M-80 while holding it in his mouth, his face was basically pealed back to his ears. Hard to look at.
