I heard this earlier today on Radio 4, it's pretty funny to hear them discussing it seriously and the interviewer trying not to laugh.

EDIT: My take on the whole "are infected actually zombies?" argument.
The term 'zombie' refers to a mental state, not a physical state. When people say they feel like a zombie, they're referring to mental weariness more than just being physically tired, and the 'Zombie' cocktail is named so more because of the mental effect of the alcohol, rather than the physical effect, therefore the infected like in Left 4 Dead, Rabid and 28 Days/Weeks Later are zombies due to their mental state, despite not actually being reanimated corpses.
Besides, real life zombies aren't actually people who have died and come back to life, they're people who are under the influence of a powerful neurotoxin, mind control drug and a form of hypnotism, like in the case of Clairvius Narcisse, as documented in the book The Serpent and the Rainbow by Wade Davis.
Also, not all reanimated corpses are zombies. A mindless reanimated corpse is a zombie, but a reanimated corpses without diminished mental faculties is a Ghoul.
