Last year I was Charlie from It's Always Sunny. It was pretty awesome. Spoiler "I'm living in a world of darkness!" Being obliterated was part of the costume. There was a football game that night, so I wore several layers under the long johns but still froze my balls off. I think I'm going to be a lumberjack this year... it'll be nice to have an excuse to wear warm and comfortable carhartts and flannel out on what will likely be a cold night. I could feasibly make a badass (and fake) double-bit axe with a handle and foam, but that probably wouldn't be very safe in my hands.
