Several years ago a co-worker tried to prank me and switched my keys around on my keyboard. I never noticed because I type by feel and not by sight. Well, a few months passed and it was never an issue for me and my co-worker didn’t say anything to me as he forgot about it. Then one morning I got locked out of my computer as I forgot to update my password within the allocated time per my company’s policy. I had to get IT involved to get me access to my computer. The old IT guy who hunts and pecks for keys was at my computer trying to troubleshoot and couldn’t figure out why his admin credentials wouldn’t let him sign into my computer to reset my password. He had to call corporate support and talk to them for 30 minutes and then while on the phone with them, he all the sudden turned to me with a stern look and got red in the face and said sharply “What are you trying to do here!” He had finally realized that a few of the keys were switched around and thought I was trying to prank him. I of course had no idea what he was talking about but thought it was hilarious that someone tried to prank me and inadvertently pranked the IT guy, who was pissed.
