I work out of an office shared by several people. We mess with each other constantly.
We've hidden one of the cordless phones inside one guys computer case. He could hear it ringing, and it was coming from near his computer, but he couldn't find it.
Ran an extension cord to the power cord of a computer monitor at an adjacent desk. Plug the extension cord into a power strip and leave it on the floor under the desk. Whenever the guy at the adjacent desk is working on the computer, the guy at the other desk can switch the monitor off with his foot on the power strip switch. This went on for DAYS.
Before we left for the day, we took a radio and turned it up full volume and hid it in the ceiling tiles. Whenever someone on the oncoming shift keyed up their radio in the office, there was a bunch of backfeed and nobody could figure out where it was coming from. At least for an hour or so.
And this one was incidental. Before leaving for the day, I hid a coworkers cell phone under his keyboard. I figured he would throw a fit, damn near disassemble his desk until he lifted up the keyboard and found his phone, then calm down and wonder how his phone ended up there. It worked out precisely to plan. Except the part about lifting up his keyboard. And calming down. Apparently he moved the keyboard around but the phone somehow stayed under it. He blamed the rest of his shift for messing with his phone and even blamed a couple of them directly for stealing it. And by the time I came back in 12 hours later, he had even called up his provider to cancel his phone plan and order a new one. When I showed him where it was, I could see a momentary flash of rage, then all out humiliation as he realized how inappropriately he had overreacted in the past 12 hours.
