A policeman was following a car along a fairly straight road when it started swerving erratically to the left, then to the right. The policeman stopped the car and said to the driver "Miss, why are you driving so erratically?".
"To avoid the trees in the middle of the road" came the reply.
The policeman looked around and scratched his head, then said "I'm sorry to tell you, but the only thing for miles that resembles a tree is your air freshener hanging on your mirror".
