On second thought, "Don't Jerk and Drive" was too risque for the state of South Dakota.
That public safety campaign, intended to raise awareness about the dangers of jerking the steering wheel on icy roads, played on the double meaning of the word "jerk," which can also be a euphemism for masturbation. Officials admitted to the Argus Leader that the double entendre was intentional.
What wanker thought that slogan would be a good idea?
