My brother's Halloween costume:
We brainstormed it all month.... Originally he was going to be a robot ("Matthew Tron 5000") and act like a robot, but have a ghost sheet OVER him, so he "was" a robot going as a ghost. Unfortunately the end result of the box was a lot bulkier than we intended so we ditched the ghost idea.
Sadly, nobody at the party got the concept at all. Some posed for pictures, but most were too drunk to care. Actually a really shitty night, to tell you the truth.
