this isnt my belief but when my sister was little she was practising a song for her christmas play at home for weeks and kept singing 'we are fluffy shepards' we were all quite confused as to why the shepards were fluffy. it wasnt until we went to watch the play and heard the class sing 'we are scruffy shepards' that we realised she'd been singing the wrong words!
