I used to use the holiday to face my worst fear... If I were inclined to do it this year, I would go as George Bush...
In the past I've gone as an old hag, a kidney riddled w/cancer, a freshly dead corpse w/a maggot on the breast (costume used twice w/babies in the maggot costume
), a rat, an alien invader/warrior, a succubus... um, I can't think of any others off the top of my head... I did want to go as an airplane hitting the twin towers in 2001, but was talked out of it by my "friends..."
