In a world where people starve, are neglected, tortured, and killed by drones, I find the idea of being offended by a joke vaguely decadent.
Think about your eyeballs when you're trying to sleep, or your eyelids. How tight they're closed. Whether they're rolled back right now or aimed straight at the ceiling? They feel straight. Why do you still see swirls even though it's dark outside your eyelids?
