Air Freshener

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 !
