What has been the best act of revenge you have taken against your bad boss?

My supervisor has become a real witch in the past 2 years. She used to be a real sweet lady who I could share things with. She makes snide remarks, looks for minor things and blows them up. I treat her with utmost respect with always kind words and a cheerful attitude, no matter what she has ME do (and not the women in our work center). It drives her CRAZY that she can't tick me off! hahahahahahahaha

it wasn't anything I did, but I saw him a year later selling display ads to small strip center businesses for a throw-away weekly advertiser.

Sa-weet. There is justice in the world.
