I would have thought that it was the 'little boy who lives down the lane', was the one being marganilised here!
The black sheep has the power, because it has something that everyone wants!
I mean, why was that little boy confined to 'down the lane', what had he done?
........in all seriousness, this changing traditional rhymes in the name of Political Correctness is the world gone mad. Besides, is it not giving the youngsters messages that there may be something wrong with 'Black' if we are avoiding even mentioning it?
