I am going to go to the thrift store and see what I can find. Last year, I went as a censored person. Basically, I had old sunglasses with a black piece of cardboard. It was epic.
The year before that, I went as a giant midget, but I wasn't committed to that idea.
The year before that, I had a paper bag over my head and I was in the witness protection program. All of those years, it was a last minute idea. In fact, i even tried to go as the Metal Gear Solid box. Didn't work out that well. I hope I have given someone a cool idea.
