Whats your best call center or IT story?

I was once called onsite for a network drop not working and I was going in cold without any documentation. Iarriveonsite and they lead me to a office with a desk and network dropnear the desk and another drop near a guest chair and coffee table on the other side of the room. I was told that when the guy at the desk is using his computer guests cant get online and when the guest is online he has no internet. I grab my trustytoner get to work and find that the cable wasspliced into two cables so he essentially had one drop in the office he was trying to put two devices on which was causing a conflict. I rewire everything correctly and get him back up and running and on the way out he says he has one other problem. Everytime he turns off his office light his computer turns off along with his clock he has to reset everyday. It dawns on me at thatmoment he was using an unlicensed electrician to do all the wiring in the building he said the entire building had weird issues with the power. I let him know I can fix the internet but im not qualified to fixstupidity.
