Years ago, when polish jokes were the rage, I was at a nightclub, and a group of us were around the pool table telling those jokes. A guy came up to me really mad, told me he was polish and didn't appreciate the humor. He was really worked up and challenged me to go outside over it. Whatta you do? So, we went out, and the guy pulled a razor on me, I think he would have cut me if he'd have found a place to plug it in.
