Two friends are hiking in the woods and come to a river. They take off their shoes and clothes and go for a swim. As they come out of the water, they spot a hungry bear that immediately starts to run toward them. One of the men flees immediately, but the other pauses to put on his shoes. The first man screams at the second, “Why are you putting on your shoes? They won’t help you outrun the bear!” To which the second man calmly responds: “I don’t need to outrun the bear; I just need to outrun you.”
