Years ago I was messing with the wiring on my stereo. I removed the speaker cables from the amp’s binding posts - yeah, they were monster cables. ;D
Anyway, over time, the cable developed a 90° bend that perfectly matched the spacing of 120VAC outlets. When I let go of the cable end, it miraculously fell right into an open outlet on a power strip. It momentarily sent 120VAC @ 60Hz to one of my Klipsch Heresy II’s. Scared the living hell out of me, my wife, and the cats!
The speakers are still rocking to this day in my exercise room.
