A doctor traveling

A doctor traveling by car along a country road collides with an attorney who happens to be driving in the opposite direction.

The attorney, seeing that the doctor is a bit shaken up, helps him from the car and offers him a drink of Scotch from his hip flask.

The doctor accepts, took a long drink and hands the flask back to the attorney, who closes it and puts it away.

"Aren't you going to have a drink yourself?" asks the doctor. The attorney replies, "Sure — as soon as the police leave."
