Tree

A blonde was swerving all over the road and driving very badly, so she got pulled over by a cop.

The cop walked up to her window and asked, "Miss, why are you driving so recklessly?"

The blonde said, "I'm sorry sir, but wherever I go, there's always a tree in front of me and I can't seem to get away from it!"

The cop looked at her and said, "Lady, that's your air freshener!"
