Ever have a co-worker “rat” you out to your supervisor? Show him or her what you think of the act by filling his or her office / cubicle full of stuffed vermin. Real rats would work best, but for sanitary reasons we do not recommend going that far. Your co-worker will really be mad when they discover what you did and will probably think again before doing it again. (Also, works well for anyone who just doesn’t like rats… which is mostly everyone!)

Have a co-worker who is getting on your nerves or just want to mess with a buddy at work? Try filling his or her cubicle full of balloons and see how quickly it pisses your co-worker off! Then take a picture of it for posterity’s sake.
