I'm feeling a bit dark today as I'm sure you can see. You must have a sense of humor for these. If you don't, forget it, don't watch them.
"The Tale of How" by The Black Heart Gang. I chose this for it's Boschian qualities. It's also as though Gorey, Tim Burton and Neil Gaiman collided. Also, it's a visual feast. You must listen closely to really get it though.
A good one By Edward Gorey - "The Beastly Baby!" (This baby is Stewie before there ever was a Stewie) Warning, quite irreverent. Any decent person shouldn't think this is funny, but I do!
