BEST Politically Correct Halloween Costume EVER

My college friend that lives out here just invited us to an After Halloween-Halloween Party on Friday and we decided we needed to come up with a last minute costume idea. Nothing scary. Nothing that requires face paint or a mask. Nothing sleazy or revealing.

Well, we started brainstorming what we could throw together on a whim and the following conversation took place:

Emmmm: We could be something "DC."

Kimmmm: How about the Washington Monument?

Emmmm: How?

Kimmmm: All we have to do is wear something white that's pointy at the top and have a light that flickers.

Emmmm: Okay, let me get this straight. You think we should wear a white gown or robe, a white hood that comes to a point at the top, and carry around something that flickers, perhaps like a torch? And you don't see any problem with this???

Needless to say, the Washington Monument idea fell through, but we're still looking for ideas. This is where we need your help. Please post comments if you have any great (preferably funny and original) last minute Halloween costume ideas.
