A blonde woman is pulled over on a by a police officer for swerving. He asks her, "Mam, why were you swerving all over the road?"
She looks relieved, "Sir! I'm glad you're here. I looked away for a second then there was a tree right in front of me. Then I swerved left and another tree was right there. Then right, then left."
The police officer bends over and looks into her car and reaches for the rear-view mirror, "Mam, this is your air freshener."
