Well that was dumb...

Ye Olde Electric Shock story, nothing like one of those to get yer heart pumping.
This one’s a Beaut too
My first job out of high school as an electrician‘s helper, I don’t know how we land the job but it was already half finished, but it was a machine shop that Pratt and Whitney was going to use. My boss set me up with a scaffold on wheels, 4 tiers high. He told me he had some errands to run, and to start wiring up rows of fluorescent light.
I was the only one there, so I backed my car right into the shop, popped the hatchback, turned my speakers around, started rocking out and got to work. I was going along good for a while -wire a light, no reason to get down, grab the steel roof trusses and scoot the scaffold along to the next light.
I get done with one light stand up on the platform grab the rail of the scaffold with one hand, and grab the steel truss with the other and Wham! I’m buzzing like a hive of angry bees. It was all I could do to let go of that ****. I’m damn lucky I didn’t then fall off, so I sat there for what seemed like an eternity with my knees shaking like hell. I got down and went and got some lunch, and around that time my boss shows back up and I tell him what happened. We start probing around and find that there was a loose wire in one of the lathes. The whole machine was energized and my scaffolding was bumped up against it.
I feel like I cheated the Grim Reaper twice in less than a minute on that one.
