I'm going as Bad Santa and I'm going to get **** faced and cuss the whole time. I'm hoping to bang some chick in the back seat of my car. I'm going to stop short of pissing myself.
I went as a Scottish soccer hooligan a couple of years ago and made a kilt out of a plaid blanket and belt. This year I'm wearing this as a Halloween costume. http://bbs.clutchfans.net/showthread.php?t=119073
My financially unsound (poor) friend had a very creative costume last year. His name is Tom and he had a nametag that said "Hell, My Name is Tom". Then he had a small piece of cardboad with a hole in it, went up to random people and looked through the hole. (Peeping Tom) Not many people really got it, and in fact many women found it quite disturbing, especially when he was standing right next to them for a few minutes before their daft drunk asses knew what was going on. I thought it was hilarious. This year I'm going as the same as last that's probably the easiest way to get PLENTY of attention and dozens of photo requests: Waldo. Homemade costume, and it's not some crappy jeans and a red shirt...it's down to the finest detail; Dickie's blue pants, painted red/white stripe shirt, nerd glasses, walking stick, scroll, knitten cap...too much effort not to use it more than once.
