Hey, there is undeniable importance to the psychedelic pickles! I mean, think what would happen if you had NORMAL pickles. Why, you wouldn't be able to tell who was associated with what! You might eat COMMUNIST pickles! If their allegiance isn't plainly imprinted on their every being, someone might try something and end up not liking it, then waste the food. CHILDREN IN CHINA WOULD SHANK OLD PEOPLE FOR DYED PICKLES.
... Or they could just stock the sesame seeds and skip the pickle drama all together, but hey, where's the fun in that?
