When I was about five years old I had a "Night Light" that plugged into the power point. I was playing with it upstairs in my bedroom on my own and pulled it apart with a screw driver to see how it worked. I completely dismantled it and had the two mettle prongs that go into the powerpoint in each of my hand. I wanted to see if the light would work outside of its casing so I pressed the two metal prongs into the powerpoint and bang!
I still remember the shock to this day, it is so vivid in my mind. I was so scared that I ran downstairs to where my Mum and Dad were watching television and told them that I just electrocuted myself, my Mum decided this was a good idea to teach me about English and told me that the correct phrase was that I had experienced an electric "shock" because "electrocuted" would mean you were dead. I still do not think either of them had any idea just how close their 5 year old son had been to killing himself. I think in hindsight they must have thought I had got a static shock.
So to answer your question yes, I experienced a huge electric shock when I was young.
