We have all heard that there are certain times you should confront a wild animal with loud noises and trying to appear larger, then there are other times when you're supposed to play dead. We can never remember which one to do with the correct animal. One woman did remember and at just the right time too! A woman caught in a frightening video trying to outrun a bison at Yellowstone National Park proved that if all else fails — “play dead.” A bystander caught this footage of two visitors to Yellow stone just this last Friday, when one of the beasts began chasing them. You can see the two people take off running, but one of them trips and falls. That's when she remembers to play dead. And it works!
