You have two cows. Mysteriously, they don't calve, no matter what. Neither do your neighbors'. You are stuck with aging cows that no longer produce milk. You don't import any cows, because you are paranoid that all foreign cows are mad, so you buy robot cows and wonder why they don't produce milk either.
Even in joke, though, the French System sounds a lot better than all others:

> You have two cows. You go on strike because you wanted three cows.
