when i was a kid, I plugged in something next to my bed. The plug was only halfway into the wall, and my finger touched one of the exposed pegs.
I still remember to this day, exactly how much it hurt. My arm was all flopping around. It was like being punched and stabbed and kicked in that arm all at once.
25 or 30 years later, I still lecture kids nonstop on electric plugs. I literally thought my arm was gonna fly off.
