One going backwards is right four times. I'm not totally sure this extends your analogy appropriately, but it's an entertaining thought.

  Interesting. - A broken clock is perfectly right twice a day - A clock going backwards is perfectly right 4 times a day - A normal, working clock is probably never perfectly right

    In the second case at least four times, no?
