I was hunting last weekend and when I got to my stand, I dropped my knapsack and went a few hundred yards away to relieve myself.
When I came back, my knapsack is open, my sandwich is unwrapped and a huge shark-like bite is taken out of it. My pickle is gone and my soda is laying on it's side and it's been left open so the fizz is gone!
Later, from high up the mountain, I heard an enormous un-human belch.
