Best/Funniest Costume You Saw Today?

My favorite today were two ghostbusters walking around together. They had the outfits on with the packs and hoses on their back and everything, it was awesome! I also saw a guy dressed in a Scottish kilt and beret, red plaid. I also heard that there was a storm trooper on my campus, but I never got to see him. :-( darn college campuses are way too big for everyone to get to see the storm trooper!
