If Bluesman had added a Folklore prefix to his OP then one of those ever-so hard-working Mudcat Moderators we hear so much about would have removed it as an abuse of offially sanctioned terminology. And yet such Folk Myths and Demons have persisted since time immemorial - however so obvious their source - taking root in an Oral Tradition untroubled by reason. So well done 'catters for keeping such a noble tradition alive and (quite literally one fears, should ever they have the chance) kicking.
