Ok... just what the hell is a "rainbow sheep"?

According to several newspapers in the United Kingdom, the nursery rhymes are being rewritten so that they will not offend anyone. For instance, instead of singing “Baa baa, black sheep” youngsters in one British city are singing “Baa baa, rainbow sheep”.

Some of the other changes that have been made include changing the ending of Humpty Dumpty so the children wouldn't be upset t at he was dropped and they have removed the seven dwarfs from the title of Snow White.
