Two hunters are in the woods in deer season

Two hunters are in the woods in deer season. The morning hunt over, they head back to camp together. As they make their way along the path, they hear a loud crashing noise and look up to see a very large bear charging down a hillside. Realizing simultaneously, that they are the bear's intended targets, not to mention lunch, one of the hunters immediately takes off his back pack, drops to the ground and begins to change from his hunting boots to tennis shoes. The other hunter bewildered asks "You don't really think you can out run that bear do you?" The first hunter replies, "No, but I can outrun you."
