Did anyone else think....oh, these idiots!
The moment Rick decided to stop killing the walkers while he was inside his carnival fence (and Michonne was a distance away inside her own fence killing walkers) to instead climb the ride to go attempt to shoot a deer?
Have they just been in this apocalypse for 5 hours? Kill ALL the walkers than go hunt your stupid deer. Deer gets away? OH WELL, WHO CARES!
