What We've Learned From Zombie Movies

"Shotguns used in 75% of all outbreaks." I keep telling you guys that shotguns are the anti-zombie weapon. Except for Graybush whose accuracy deteriorates drastically as soon as he gets one in his hands. Headshot with a pistol from 100 ft away? No problem. 10 ft away with a shotgun? That's one safe zombie.
