I didn't dress up, didn't have time. But, I did wear my Punisher t-shirt to work and to give out candy. My wife had a teleconference for her work. She wore a Scream mask. She didn't talk, but did gestures like nodding her head for approval, and grabbing the mask chin for contemplation. She made it to the main screen for a minute. And this is a worldwide type conference. Haha
