Higurashi Kira, god forbid how terrible this is, but I have to watch it, half out of curiosity half for laughing at how bad it is.
Maria Holic I'm near completing, I watch the odd episode when I feel like it. Not the funniest, but still pretty good. It can make me laugh at times which is more than many others.
Panty and Stocking. Got to be in the right mood for this show, but when I am it's hilarious.
Shinigami no Ballad, started recently, so far it's pretty god damn awful. I will probably finish it though just because it's only 6 eps long. But eh... no motivation to watch the 3rd ep after the first two were so difficult to get through.
