If you thought that opening a bottle with your teeth or cutting yourself while shotgunning was dangerous, this is about to be a rude awakening. Without damaging either bottle, this guy opens his beer with a frigging chainsaw. Just casually revs that sucker up and pops open his brew. Needless to say, don't try this at home or at your next rager. You don't want to be the guy who brings a chainsaw to the party, it's bad looks. Check out the video after the jump.
