The pickling pickle
Imagine as a pickle maker, you make an incredible batch of pickles. Now that the perfect combination of flavors and spice have been reached there is a frenzy of eating them, leaving the pickler with none such great specimen left. Imagine again a subpar quality has been fermented; they may sit out until they go bad, or just be thrown out all together. In either such outcome, the pickler is left with no great pickles to be had. Hence the pickler's paradox. aka shai's pickle.
