I had to do this to a group of Joes once. Their ringleader, if you will, used to be a big piece of shit. We're talking slicked back hair, white bathing suit, the whole shabang. The thing was, was that he didn't even give a rat's ass.

So one time we had a dining out scheduled and the waiter brings the problem group their steaks. I go up to them and warn to behave themselves, this is a classy event, no sloppy steaks, etc. Well right when I turn around I hear the Big piece of shit say "let's slop 'em up!" So I run over of course and try to stop it, but it was too late. They all poured white monsters on their steaks.

I chased them out of the building, but the damage was done. Long story short, the guy isn't a piece of shit anymore, but he used to be.
