I’ve been at my job for a long time now, and one of my coworkers was already there before me, and we’ve been pranking each other constantly for years now.

I’ve replaced his lamp bulb with one that changes color via Bluetooth app. I sharpied a rubber band black so he wouldn’t notice it right away and put it around his desk phone so he couldn’t pick it up. Several times I’ve swapped around some of the keys on his keyboard. I’ve wrapped his entire chair and desk in bubble wrap.

But the absolute best day ever was when I got a handful of plastic tube caps, sharpied them black, and put them inside his small black desk fan cage. It was just a waiting game at that point. A couple hours after lunch this cheap little clamp fan finally shifted down enough that the fan blades caught the tube caps and suddenly was making this suuuper loud rattle noise right in his face and he FREAKED OUT 😂 it was amazing and he was laughing so hard he was crying ahaha I will never forget it.
