3. Katamari Damacy Intro
This entry is creepy in a different way: while most of the cases I have written about come from strange stories, scary scenes, or games messing with your head, the intro from Katamary Damacy gets its place in this ranking because of its "extreme colorfulness". It's one of those videos you don't want to be discovered seeing; it's plain weird, and so happy, so lively, so full of energy that it could haunt your sub-conscious forever. Also, the King's pants! Once seen, it can't be unseen!
