Sometimes people do stupid things, this is one of them. I have been trying to imagine the circumstances that lead up to this putz pouring two gallons of gasoline on a pile of tinder in a dry field, but I imagine that it probably involved beer.
You would expect this guy to be really badly injured, but I am convinced that there is some kind of cosmic ward of protection that is conjured when you mix rednecks, beer and fire.
Somehow, if you have these three key elements you can do the craziest, stupidest shit and no one will get hurt. Please note that I do not advise testing this theory.
