Helpful hint: I knew someone years ago who would take his electric meter out, turn it upside down, and plug it back in. The four prongs on the back make that easy to do.
His claim was that he would let his meter run backwards for a week and doing that would take two weeks off of his electric bill. Interesting theory.
My uncle happened to manage the General Electric Meter Division in Dover, NH. Several years later I told him the story. He was very excited to tell me that they had fixed that flaw and if you inverted your meter now it would run twice as fast forward.
A large restaurant owner in Saugus, MA paid someone to take his meter apart and change the internal gears so that it ran at about 1/3 the correct speed. That went on for many years until he was caught and convicted.
