(e a 8 de Dezembro,
Pretend to be a Time Traveler: One of the ones I've done in real life was to get my friend to shave his head, draw a bar code on the back of his neck, stagger up to people and say "WHAT YEAR IS THIS" then run off. Then a second person walks up to that same person later with a photo and says "HAVE YOU SEEN THIS MAN"? It helps if you have a little eyepiece or small piece of obtuse technology on you.)
