What to be for Halloween 09?

What should i be for Halloween this year? I was going to go as Magenta from Rocky Horror Picture Show but the movie Halloween 2 kind of ruined that... haha and it wasnt even a great movie! Anyways im 16 and i was thinking about Lydia from Beetlejuice or just something weird and TimBurtonish. So any creative ideas. I dont want to be anything like "y" or all that scary either but just something sort of twisted and awesome! thanks :D
