Many decades ago, while working at Motorola, one of the engineering workbenches gave me a very slight tingle.
I traced down the reason: The hot wire was interchanged with the ground wire!
As a result, the workbench ground and all the test equipment were continuous at 120VAC.
It had been that way for a long time. By luck there was no other grounded object within reach.
This reminds me of one place where I used to live. We were in the upstairs apartment, and them downstairs mentioned getting a tingle from the washer or the dryer, I forget which. So I put a meter between them, and found 120V. Eventually I traced this problem to the breaker box in the basement, where someone had switched around the red and white wires for the dryer outlet, making the dryer shell live at 120V all the time. That didn't take long to fix, but I've often wondered who the hell did that...
