I've noted over the years that zombies also prefer the plump flesh of voluptuous, screaming, blonde, teenage girls who are usually wearing bed clothes of some sort. I guess you could say that zombies have good... taste?
Also, one must question how it is that, although they move so very slowly, they are always able to catch said screaming, running, speeding car-driving teenage girls and rip them limb from limb?
Ah the many secrets of zombies. What fantastic lives they lead...
