Fooled Again Doctor

Middle of the night, middle of nowhere, two cars both slightly cross over the white line in the center of the road.They collide and a fair amount of damage is done, although neither is hurt.

It's impossible to assess blame for the accident on either however. They both get out. One is a doctor, one is a lawyer. The lawyer calls the police on his car phone; they'll be there in 20 minutes.

It's cold and damp, and both men are shaken up. The lawyer offers the doctor a drink of brandy from his hip flask, the doctor accepts, drinks and hands it back to the lawyer, who puts it away

"Aren't you going to have a drink?" the doctor asked.

"AFTER the police get here," replies the lawyer.
