Two friends decided to go for a hike in the mountains of Colorado, they put their gear on and headed out.  After hiking for about an hour, they came upon a bear who immediately stood up on its back legs and let out a loud roar.  One of the hikers dropped to the ground, took his sneakers out of his backpack and started to put them on, the other yelled, "are you crazy, you can't outrun a bear,"  the friend replied, "I don't have to outrun the bear, I just have to outrun you."
