You're walking home, alone, at night. You decide to take a shortcut through the woods, since your area is generally safe. Yeah, there's the odd robbery every month or two, and there were those loony cultists decades ago, but those times are over, right? Right?
Lost in thought, you realize you're half way to home, and also notice how silent the woods are. There should be at least some insects making their noise or a couple of night birds chirping about.
Suddenly, you hear a very deliberate, very artificial, very dangerous sound: "clack-clack", the sound of a lever-action rifle makes when chambering a new round. You turn around, see this creature, naked, holding a .30-30 Marlin, and he whispers: "Howdy, parndner!"
