I have to say there are many shambling mindless Americans these days. Many more than, say, 15 years ago. It seems the zombies do walk amongst us.
Although unlike traditional zombies they don’t seem to seek brainnnnz. Makes sense since they have no use for them. No for eating and not for thinking with.
I have eaten (sheep) brains. Prepared several different ways. I would not consider that a high point in my lifetime dining experiences.
Given that neither sheep not the current American Zombies make much use of their brains, I’d expect Modern American zombie brains on toast to taste about the same as the sheep did.
