<human>: Background: I work as part of a small IT team for a department (in a larger company) that mainly looks after localized systems but sometimes we get requests to help with the main IT departments workloads (such as moving machines and collecting their information).

So naturally as part of April Fool's day, I wanted to setup a little prank at my office.

I sent around an email stating that:

*
"Today is the first of the annual Keyboard and Mouse Maintenance checks.
This has been put forward by (the main IT department) in order to ensure that all PC equipment is kept up to a useable and safe standard.
At some point today, the earlier the better, would you please remove the keyboard and mouse from your computers, and attach a sticky with your name on it, then place it on the counter space by IT?
We will then test and make sure the equipment is fit for use, and return the devices back to you. Thank you for your co-operation."
"*

To start with people called it out as a hoax and laughed, but I was not to be beaten!
**Now here's when I went wrong.**

I wrote a second email stating that this was a not a joke and that people really did need to comply as part of health and safety checks on all the hardware.
This time around, the whole bloody department took me serious, and my desk was piled up with keyboards and mice all morning.

**I had stopped a whole department from doing their job!**

I had to run back every few minutes with a keyboard in hand, saying how quickly I've managed to test the equipment.

Just before lunch time, I wrote my last email, stating that the whole thing was a hoax and all that, but I set the email to a delay to be sent 5 minutes after I took lunch.

I came back to the office to a lot of angry faces, and had a stern talking to from my manager about how it was not appropriate to make claims that other departments wanted this to happen.

Provide a brief overview of the text.
