Tree

As a blonde crawls out of her wrecked car, the local sheriff asks her what happened.

The blonde began, "It was the strangest thing! I looked up and saw a tree, so I swerved to the right. Then I saw another tree, so I swerved to left. Then there was another tree, and another and another ..."

The sheriff thought for a minute and then said, "Mam ... I don't know how to tell you this, but the only thing even resembling a tree on this road for thirty miles is your air freshener."
