Don’t ask me how Brian can smell without a nose… Or perhaps he has an even BETTER sense of smell because there’s no bulky nose in the way? I forget where your scent receptors are located. But that’s probably already too much thought on that subject.
I’m not sure if this is the first strip that offers subtitled zombie dialogue or not, but I really liked that idea and used it quite a bit once I got started on it. I just like the idea that they speak this complex, nuanced language of grunts and groans, unknown to humans.
