When I was young I had one of those little electronic robot building kits. What would normally happen is you would plug wires into a battery pack that would run the control panel for your little robotic arm or whatever.
Well, one day the batteries went dead so I needed another way to get power to it. EVERY kid knows that you can't plug wires (or knifes or anything dangerous) into a wall socket so I went out into the garage and found the longest extension cord I could find. The longer the better, I assumed.
I figured by the time all the electricity when through the entire extension cord it would be safe for the robot arm.
I proceeded to catch my bed on fire.
