Happy Halloween!

Halloween kind of crept up on me this year.  In past years, I've gone to a party thrown by a guy at work, and getting ready for that seems to get me ready mentally (not that there's much to "get ready" for, just costume/candy mindset).  This year, we didn't go to the party, so I wasn't ready.  I always have a Spider-Man costume at a moment's notice, but usually only use that as a fallback, especially since there's no mystery as to who's in the Spidey suit every year. What will/did you go as?
