1. Hershel's Infinite Ammo Shotgun
In possibly the Citizen Kane of Walking Dead errors, I present to you Hershel Greene and his infinite shotgun of doom. Oh sure, you all saw this coming, but if I didn't put it in then I would've caught all sorts of hell. For those who don't know, when the Walkers got bored of being sidelined for farm management in season 2, they decided to re-announce themselves in fine style by turning over the Greene family farm. Obviously, Hershel's not happy about this, so like any true Southern farmer he stands by his porch and shotguns down the intruders. And to be fair, he does it for a long time a really long time. He reaches 25 shots before he eventually has to reload, breaking any sort of weapons-based realism with something approaching Metal Gear Solid logic. He's saved by Rick while he's reloading, and I guess he's got to be thankful he turned up when he did judging by how many shells that magical boomstick houses, the Greene patriarch would've been reloading for a long, long time. http://www.youtube.com/watch?v=Hp0hcqWNjjE
