Two campers are walking through the woods when a huge brown bear suddenly appears in the clearing about 50 feet in front of them. The bear sees the campers and begins to head toward them. The first guy drops his backpack, digs out a pair of sneakers, and frantically begins to put them on. The second guy says, ‘What are you doing? Sneakers won’t help you outrun that bear.’ ‘I don’t need to outrun the bear,’ the first guy says. ‘I just need to outrun you.’
