There was always that one kid that you knew while growing up that would fight his dad. Maybe would Dad would get drunk and pick a fight. Maybe the kid was an a-hole. But regardless, they'd eventually come to blows.
In this video, it appears as though Dad is the aggressor. He's calling his kid names and Junior holds back for a while, but once it gets physical, IT GETS PHYSICAL. Dad is probably really regretting this whole interaction now.
