Smell it?

A woman took her car to her mechanic.

She told him, "Every time I take my friends out in my car, there is this terrible smell. It never happens when I'm alone."

The mechanic was puzzled, so he said, "OK, let's go for a spin and see what the problem is."

Off they went. She drove down a one-way street in the wrong direction at 60 MPH, swerved, hit the curb on both sides of the street, narrowly missed three pedestrians, ran several red lights, and just missed a policeman. They returned to the shop and she said, "There it is now—there's that terrible smell. Can you smell it?" The mechanic replied,

"Smell it? Lady, I'm sitting in it."
