"So I'm doing this Polish chick, right. All of a sudden I get this notion that slamming a vase over her head would be sweet. Ya know, like a donkey punch, except with a vase. Long story short, she filed a lawsuit against me for "assault" and "battery." I didn't hit her with a battery. It was a vase! Stupid court."
