When I was a kid we used to holiday at my aunties place. She had an ancient TV, but the knob had come off the channel selector. The only way to change channels was to poke a screwdriver down there to turn it. Trouble was it was like a game of operation, you had to be real steady not to touch the sides and get shocked, even through the screwdriver handle.
That video reminds me of that TV.... so many shocks in my youth.
