We had a prank war going on in our office that lasted for weeks. It started with small things, like putting a fake spider in someone’s drawer or swapping out their computer background. But it escalated quickly. One day, someone filled a coworker’s cubicle with balloons. Another day, someone put a bucket of water on top of the door so it would fall on the next person who walked in. It was all fun and games until someone got hurt (nothing serious, just a sprained ankle from slipping on a banana peel). We decided to call a truce before things got even more out of hand.
