Minor quibble: This implies that electricity only takes the path of least resistance. Electricity actually takes all available paths in inverse proportion to the impedance of the paths. This is why grounding rods don't keep you from being electrocuted. I'm looking at you, sketchy lamp-post.
Good clarification. When I was a kid I found out that standing on the edge of the kitchen sink and touching the pull chain on the lamp in the soffit overhead would 'tickle'. I was so proud when I told mom and dad! :P
