Two campers were hiking in the forest
When all of a sudden a bear jumps out of a bush
And starts chasing them.
Both campers start running for their lives,
When one of them stops
And starts to put on his running shoes.

His partner says,
"what are you doing?
You can't outrun a bear!"

His friend replies, "i don't have to outrun the bear,
I only have to outrun you!"
