How can you dunk one Oreo cookie for five or ten second and it gets all soft and milky and tender.
Then the next three you get from the same pack can be dunked for like a full minute and they stay as hard as concrete?
Then the final one you grab, you assume, is going to be like one of the non-cooperative ones, and you dunk too long and it disintegrates into a gazillion particles in the bottom of your milk.
