The police pulls a car over on a country lane and approaches the blonde lady driver.

"Is there a reason why you're weaving all over the road, madam?", asks the officer.

The woman replied, "Oh thank goodness you're here. I almost had an accident. I looked up and there was a tree right in front of me. I swerved to the left and there was another tree in front of me. I swerved to the right and there was another tree in front of me!"

Reaching through the window to the rear view mirror, the officer replied, "Madam, that's your air freshener."
