got the full story from my dad:
-pulled up to the burger king drive through and a guy was just standing in the way. my dad rolls down the window and tells him to get out of the way
-guy goes over to the window of my dad's car and starts yelling at him for some reason
-guy throws a slushie in my dad's face and then starts to walk off
-my dad, and i quote, "just fuckin blacked out" and, in an apoplectic haze, hits the dude with his truck, not hurting him but flinging him a respectable distance and knocking him to the ground. i at this point ask why he didn't just get out and punch him. he says "i don't know something just came over me", while understanding this isn't an excuse to hit people with your truck
anyway my dad's on probation now
