Two guys are out hiking. All of a sudden, at a distance, they see a hungry looking bear running towards them.
They look around but there's nothing to climb.
The first guy gets his sneakers out of his knapsack and starts putting them on.
"What are you doing?" asks the second guy in panic.
"I figure I'll make a run for it."
"Are you crazy? You can't outrun a bear!"
"I don't have to outrun the bear." Says the first hiker, "I just need to outrun YOU."
