Dui?
Two drivers collided on a country road. One was a lawyer, and the other was a doctor.
The lawyer, seeing that the doctor was a little shaken up, helped him from the car and offered him a drink from his whiskey flask.
The doctor accepted and handed the flask back to the lawyer, who closed it and put it away.
"Aren't you going to have a drink yourself?" asked the doctor.
"Sure, after the police leave," replied the lawyer.
