The group must chose "it". Then the group should form a circle with "it in the middle. "It" then points to a person in the circle repeating the word "zip" or "zap" and counting to five. If "it" says "zip" the chosen person must reply with the name of the person on his right, or if "it" says "zap" he/she must reply with the name on his/her left. If s/he is wrong then s/he goes into the center of the circle.
