Run Fast

Two guys were walking through the jungle. All of a sudden, a tiger appears from a distance, running towards them.

One of the guys takes out a pair of 'Nikes' from his bag and starts to put them on.

The other guy with a surprised look on his face exclaims, 'Do you think you will run faster than the tiger with those?' His friend replies:

'I don't have to out run it, I just have to run faster than you.'
