The most fun practial computer joke I did at work was to use the less secure idea with start-up and shut-down applications on the company's Mac's. I just made an alias of computer A's shut-down application and used it in computer B's start-up items folder. So when Computer B stared his computer he also automatically closed down computer A's computer. Of course I did this on more than one computer, I had about 4 or 5 computers set up like this. Left work and waitied for the phone call from the frustrated computer tech (who really didn't know much about Mac's and this was my little game on him to show that he needs to study more). Had him turn off all the plug-ins before starting the computer (of course that took care of the problem, but then no other software was working satisfactory). So on his next call I told him to just turn off the start-up and shut-down folders. After all, they did need to make the deadline for the newspaper.

This reminds me of a practical joke that was played on me.
It was in the first or second month of my job as a supporter in a helpdesk. We supported users from the entire world mainly on mainframe systems.
We had a message system called "Mess" which was a very simple form of a chat that worked by sending a simple text message from one mainframe terminal to another. This was used for quick help to users out in the world. And often worked even when users had problems logging onto other mainframe systems.
Now the joke was played on an afternoon with little work. I was sitting with my back to the "Mess" and in a office next to mine with an open door a co-worker was sitting. He could see me but I had my back to him.
Then the "Mess" beeped, I turned around to see what it was. A user said he had problems starting TSO on mainframe 1, could I please recycle his terminal "abcd".
So I logged on to NetView to see the status of that termnal, it looked fine but the user said he had problems so I recycled the terminal (meaning disabling and enabling network connectivity).
My screen went black and I was back in the login screen............
