The Mold

You figure that bears are stupid animals and that if you pick up a branch and brandish it you will appear to the bear much larger than you actually are. You pick up the largest branch you can find and start swinging it in a circular motion. The bear seams undaunted and charges you. You keep swinging the branch until the bear reaches you and with one swipe knocks your head clear off. Turns out that when a mother bear is defending her cubs a mere branch won't scare her off.
