Users and Cables
I've always been equal parts fascinated and horrified at the things I've seen people do with cables. Like bending your standard AC cable to a 90 degree angle just to make the computer fit "perfectly" in a specific spot. One time when working as a repair tech a unit came in where the user was complaining that the USB port didn't work. A quick visual inspection revealed that the pins in the port had been bent up sort of like an accordion. Those are glued onto the plastic bit pretty well, and of course the Type-A connector designed to plug into it has pins that are supposed to slide over top of the port's pins. So I can only imagine the amount of effort it took someone to overcome both the force of the glue AND the inherent strength of the metal the pins are made out of when you're pushing straight on.
