Sam and Dave are camping in the wilderness. Sam turns and notices a bear about a mile behind them. They decide to pick up the pace a bit. However, it soon becomes apparent that the bear is following them, in fact the bear has broken into a run.

Sam quickly removes his backpack and rummages through it. Astonished, Dave asks what he's doing. Sam replies that he is going to remove his hiking boots and put on running shoes.

"Are you crazy?, you'll never out run a bear by wearing running shoes" says Dave.
Sam replies," I don't have to outrun the bear, I just have to outrun you."
