Two men were backpacking in the woods when all of a sudden they happened upon a giant bear. The bear stood up and began to circle towards the men with a toothy roar and claws bared.

The first fellow looks at his friend who has pulled a tennis shoe from his pack and was putting it on hurriedly. "That's not going to do you any good" said the first man, "bears can run over 30 miles an hour."

The second man just pulled out his second tennis shoe and began putting it on. The first man turns again to the first man, as he could feel the bears breath as it circled even nearer and said, "I told you that even with those shoes on you cannot outrun a bear. Bears can outrun a quarter horse.

The second man says as he sprints away, "I don't have to outrun a quarter horse, I just have to outrun you!"
