I don't really know what my favourite monster is, but I can't say I really know of many. When I was a kid I used to come up with all sorts of monsters, but I can barely remember them now. Cookie Monster is pretty awesome though. Heh, and my Dad's nickname for me is Monster
EDIT: I suppose anything with massive sharp teeth and huge claws appeals to me :shrug:
Yay, FFAF! But hey, I find Lady GaGa scary too. Even more that Gillard.
