A doctor traveling by car along a country road collided with an attorney, who happened to be driving in the opposite direction. The attorney, seeing that the doctor was a bit shaken up, helped him from the car and offered him a drink of Scotch from his hip flask. The doctor accepted, took a long drink and handed the flask back to the attorney, who closed it and put it away.
"Aren't you going to have a drink yourself?" asked the doctor.
"Sure -- as soon as the police leave," replied the attorney.
