@blatham,
Well, I don’t know that it’s something that happens every weekend to the same kids but I know I was in a fight or two in college...always while drinking. I bet at least 50% of my guy friends were too. I bet 100% of my guy friends have seen a fight break out with their friends.
I don’t think the bar fight or even getting arrested over it is disqualifying...lying about it may be though, in addition to the other silly and obvious lies he told under oath.
