Two guys are out hiking. All of a sudden, a bear starts
chasing them. They climb up a tree, but the bear starts
climbing up the tree after them. The first guy gets
his sneakers out of his knapsack and starts putting
them on. The second guy says, "What are you doing?"
He replies, "I figure when the bear gets close to us,
we'll jump down and make a run for it." The second guy
says, "Are you crazy? You can't outrun a bear." The
first guy says, "I don't have to outrun the bear...
I only have to outrun you."
