"accidentally catching fire". As opposed to doing it on purpose I guess.
A performer accidentally catching fire during a fire-spitting stunt
Should've doused him with the plentiful diarrhea in the area, would've been out in a second.
Paraffin (kerosene) is the fuel of choice. Naphtha is less toxic, but is more flammable. If you want to be a real idiot, like this Indian, go with the petrol. It will burn off the stink, too.
They have a gigantic 50 gallon drum of water within 1 foot from him and they still let him burn!! Utterly amazing
