Lion In The Jungle

Two guys in a jungle, come around a corner and meet a lion head-on pawing the ground.

One guy ever so carefully reaches into his knapsack and slowly takes out a set of Nike running shoes, never once breaking eye contact with the lion.

2nd guy hisses: "What are you doing, you can't outrun the lion"

1st guy says: "No, but all I have to do is outrun you"!
