Halloween?

Here I am, miles upon miles upon kilometers from home, where all of my costume clothing is in boxes, and I have a Halloween party to go to on Saturday night. Who can I dress as this year? My only ideas are the most obvious choice of this year: Sarah Palin (but do I have a suit? and how does she get her hair to do that anyway?) and the most obvious choice of last year: Amy Winehouse. Yes, I can probably tease my hair into a modified beehive and put on some eyeliner, but could I find a bunch of fake tattoos to put all over my arms? Do I have sufficiently slutty clothes? Its a tough one this year.
