When I was a a kid, I went up on an apartment building's terrace with a friend, to chill, catch some sun tan and listen to some music. He gave me a power chord end to hold and went inside the house to plug the other one into the wall socket (his apartment was on the top level).
What I failed to notice was that my end was partially uninsulated. You can all guess the result. I got shocked pretty badly at 220 V. My right hand was stuck to the chord, muscles contracted... It was impossible to drop it. I remember having time to yell at him to remove the plug two or three times, so I must have been "connected" for 10-15 seconds at least.
All I got from it was a really nasty skin burn (like carbonized skin on my middle finger), so I find this story hard to believe.
