Once again I relate so hard to that hippohorse thing
Seriously. Fuck those parmesan shakers. You can't use the hole because they get clogged with clumps of cheese, and you can't use the opening because then it just comes out all at once. I've recently just given them up, and instead go for decently sized parmesan flakes. You can't sprinkle them the same, but parmesan cheese flakes drenched in sauce make for a great opener to a spaghetti meal.
