Highway trouble (0)

A police officer pulls over a car with a young blonde driver in it....

Cop : "Miss, this is a 65 MPH highway, why are you going so slowly?"

Blonde : "Officer, I saw a lot of signs saying 22, not 65."

Cop : "Oh miss, that's not the speed limit, that's the name of the highway you're on!"

Blonde : "Oh! Stupid me! Thanks for letting me know, Ill be more careful from now on."

At this point the cop looks into the back seat of the car, where the passengers are shaking and white as ghosts.

Cop : "Excuse me miss, what's wrong with your friends back there? They're shaking something awful."

Blonde : "Oh... We just got off of highway 119".
