You Say Peetato

So, we have established from this story that Steven Andrew Plank is a screwed up man. I mean, who throws urine on his dad for cooking potatos on the stove? Where else would one cook potatos? Not only did he throw his dad's own piss on him, but he threw the potatos on him! Gees! What a messed up son. I wonder how long his dad had been living with him. And it's never mentioned how the poor old guy is doing. Was he burned? Even if he wasn't, how exactly do you recover from your son hucking your own pee on you?
