How to Outrun a Tiger

Two friends are walking in the jungle.

Suddenly a tiger appears in the distance running toward them. One friend pulls a pair of 'Nikes' out of his bag and quickly puts them on.

With a surprised look, the other friend says, "You don't really think you can out run that tiger with those?"

"I don't need to out run the tiger", his friend replies, "I just need to run faster than you".
