Pulled a funny on the developer in the cube across from me. Plugged in a second mouse into his computer, and would occasionally wiggle it a bit. He was absolutely sure the office was monitoring everything he did. "It moved again!" Walk around to his side -- nothing. "I'm not crazy. It moved"
We did that in my office one April Fools' Day. Switched the wireless receivers on the mice of two coworkers whose desks were across from each other. It was a funny moment but of course they figured it out quickly!
