Two men are out for a walk in a forest when they’re confronted by a huge grizzly bear.
“Stay calm,” says Tom to Jim. “Don’t move a muscle.”
Jim takes off his rucksack and starts to put on a pair of trainers. Tom says, “Get real Jim, there’s no way you can outrun a grizzly bear.”
“That’s true,” Jim replies, “but all I have to do is outrun you!”
