A Scotsman who was driving home one night, ran into a car driven by an Englishman. The Scotsman got out of the car to apologize and offered the Englishman a drink from a bottle of whisky. The Englishman was glad to have a drink.
"Go on," said the Scot, "have another drink."
The Englishman drank gratefully. "But don't you want one, too?" he asked the Scotsman.
"Perhaps," replied the Scotsman, "after the police have gone."
