Zombies don't poop. In fact, they don't suffer from any of the inconveniences we mere mortals are bothered with.
Watched episode 1 of the new season last night. TWD airs on a channel I don't have in my bundle, but I have other ways of watching what I want to watch. Good to be back into this great series. I have zero knowledge of the TPBs/comics, which is probably a good thing, because I can just enjoy it for what it is: damn fine zombie gore on the small screen!
