Funny story: I was at a costume party, and I was Master Chief from HALO, and I saw another person as Master Chief too! So, guess what...we both entered the contest as the "Twin Master Chiefs" We didn't win any of the trophies, but my DAD won the "Least Effort" on the costume contest (He was wearing a shirt saying "costume not found"), and guess what, HE DIDN'T EVEN ENTER IN THE COMPETITION! The only thing I won that night was a Halloween Twister game, and the guy I was competing against was a chubby man that looked like he ate everything on the McDonald's menu. And that's the story of how I gave up on costume parties for life.
