doubletap is rule 4.
Rule 2: Beware of Bathrooms: Really not just bathrooms any good. apocalyptic zombie survivor should know better then going into a bathroom, small closet or any other small room with only one way in or out. Only thing stupider to go into then a bathroom is a movie theater. Lots of places to run around before you get eaten.
