Surprise parties usually mean confetti and everyone jumping up as you walk in the door. This party involved Nerf guns and a house full of zombies. Sam Ross loves zombies so his wife had all of their friends dress up for his birthday. Then she left the Nerf weapons at the door so he and his buddy could clear out the house and save her. They go room to room and have a blast getting scared half to death by their friends.
