nah if you try to break it up a friend of theirs thinks you are jumping in on the fight and taking a side. Let the drunk guys figure it out if they can.
But as you said its dam amuzing especially when people get beer muscle's haha swing punches and those are dam funny.
Sorry couldnt resist but some people just fight horrible. The quickest way to point A to point B is a straight line. Not many people fight that way. They think they do but.........they dont.
