Here is an interesting historical piece. Apparently, it's an 18th century Welsh ink drawing of a mother putting her children to sleep with the story of "Ddua Bawdhoelia". Ddua Bawdhoelia is a legendary black beast so loathesome that if men (or women or especially children) stared at it long enough, they would go mad with madness.
-OOGY STUFF ALERT-
If you are to look farther, you will understand the true nature of Ddua Bawdhoelia...
Yes, I have to admit it, the true Ddua Bawdhoelia is this stupid black toenail I've been sporting for about a month now. I have stared at it long enough, and it is starting to stir my imagination in dark ways. It will truly be ugly if it falls off: Grilliwch! indeed.
