It seems like we've all had our 'Darwin Award' moments when we were younger.
Best that than what I saw on TV today (did anyone else see it, I think it was MSNBC?) - this bubba type was talking about how his drinking water contained flammable chemicals, and to prove it he used his cigarette lighter to light it on fire.
Of course, a huge fireball engulfed his hand and arm. "Damn, that was the biggest one I ever done!", exclaimed he.
While you and I might have done the same demonstration, I dare say that we'd have at least used a barbecue lighter or long match to ignite the water!
