Get creative,even if it's not scary. A girlfriend of mine did a great edward scissorhands one year. Another friend of mine put a bunch of purple balloons all over her and went as grapes. You could be a 1920's housewife - especially if you're a man - or a street beggar. If you have a lover or friend you can be siamese twins or John and Yoko, or both! You could be Preparation H Raymond or the Masturbating Bear (ever see Conan O'Brien?) Or you can get really crazy and figure out a way to represent, say, that tingling feeling when your foot's asleep. Lots of ideas. Just please don't sell out and buy a completely unorigional pre-bagged costume. If you absolutely have to go as a witch or Spongebob Squarepants then atleast make the outfit yourself. Hope you like any of the ideas, good luck!
I once went as a piece of sushi. I had a white robe with a texture like rice, a reddish piece of foam on my back (the tuna), a sash of black around my waist (seaweed), and my entire head including hair painted green (a blob of wasabi). And I made a purse that looked like a packet of soy sauce.
...then the next year my costume was that I had Bush in my pocket (I was the special interests). A leopard-spotted cowboy hat with an oil rig built on top, a toy gun in my pocket (the NRA), and fake money with Bush's face on it. Oh, and a suit jacket, bolo tie, jeans, cowboy boots, and a belt with a BIG belt buckle on it.
