I’d started a new job a month before April Fools. I got to the office very early and then had the idea to put a piece of tape over everyone’s optical mouse laser. I scurried around and got everyone except the office manager, including myself. Then I left.
When I returned to the office, people stifled giggles and watched me go to my desk. I sat down, wiggled my mouse, and said, “Hey, what’s wrong with my computer?” My coworkers started laughing and came over to show me how I’d been “tricked.”
The office manager arrived a little later. I watched with my new chums as she came in, sat down, and started working without any incident. Someone popped their head into her office to ask if her computer was working, and she laughed and said of course it was. I sowed the seeds of discord: “She must’ve done it!”
And that’s how the whole office blamed the office manager for my April Fools joke. I was quite pleased about that.
