In the late 90s, there were some monitors in our library that had some serious grounding problems. You could literally touch the screen with one finger, touch your victim with the other hand, and have your pal repeatedly turn the monitor off and on rapidly at the physical spring-loaded switch - and at some point, they’d get an uncomfortable-but-not-painful shock.
Highly entertaining, guaranteed a bollocking, and after that it was back to the degaussing CHUNNNNNNNGUNGUNGUNG sound. Satisfying as fuck.
Now that’s something I’d have expected to see a wave of now, and a comm called jesuswithajob or something. lols.
