Get a group of friends together for a zombie make-up party. Once everyone looks good (and by “good,” we mean, “dead”), set a bowl of treats on the porch with a sign that says "Beware of Zombies." Whenever anyone approaches, you and your friends start moaning and crawling out of the darkness from all sides. Fright level: undead. Just be sure not to approach any kid dressed as Daryl Dixon, because that guy knows how to take a walker down.
