What is the worst piece of political correctness you have heard and where are yoou from?

im from England and it is generally accepted that that honour!!!!!! is between a school which banned the nursery rhyme baa baa black sheep and the word blackboard for fear of upsetting the black community and the worcestershire police force which has instructed its officers to stop greeting people with the words' evening all' (an old english traditional police greeting) as this might offend immigrants who are in England and in whose home country it might not be evening. it would be funny if it wasn't so serious, and can anybody tell me in which county political correctness originated. i thought it was America but a friend insists it was Canada, what do you think
