Poker face fail
Yonks ago, in a different life, I and a colleague got the task of installing some newfangled twisted-pair to replace the coaxial cabling. The offices had nicely accessible, large cable ducts running along the outer walls. And all the outlets, for power, network, telephone, were on the bottom of the duct, with the connectors being plugged in from below - and against gravity. The only obvious problem with those duts were their lids, outright bitches that heavily resisted both, being taken off and put back on. To put them back an aweful lot of fist-hammering was used. Acquired my "iron fist" there in Mr Miyagi-style.
So, one day while happily hammering along, suddenly the face of an accountant went pale, then white. Just when I was starting to worry that he might be dying he turned redish - steaming hot red! Accompanied by a screamed "I lost all of my day's work!" - it was mid afternoon.
That was about when we realised what happened: the hammering slowly but surely drove the power plug of his computer out of the mains socket. An orange socket, the ones connected to the UPS. One of us, I can't remember if it was my colleague or me, calmly said to the destroyed, steaming accountant: "you should regularly save your work - you never know when there's a crash." We left the office, closed the door and in the staircase we got the mother of all laughing fits.
