Welcome to the birthday party prank. My coworker just got a promotion. When people get promotions, they get pretty cocky. So, we took his office and turned it into a 13 year old girl's birthday party. This prank is twofold. First is the initial shock of the balloons and the decorations. Second, there's a treasure map. Because hidden in some of these balloons are some of their personal items. Staplers, phones, keys, even their mouse.
