ex-chief
I hate guys that drive around with those little plates just above their license plate that read ex-chief of the who cares fire department. The only reason to have that displayed is to try to get out of a speeding ticket. No other profession has those little plates. You never see a little plate that reads ex-sanitation engineer. As long as we're going there, how about little plates that say ex-priest or ex-con. At least then the general public will have an idea who to watch out for.
