A state trooper pulled a car over on a lonely back road and approached the blonde lady driver.

"Ma'am, is there a reason that you're weaving all over the road?"

The woman replied, "Oh officer, 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 side window to the rear-view mirror, the officer replied, "Ma'am, that's your air freshener."
