Шутка дня

So I was in my car, and I was driving along, and my boss rang up, and he said "You've been promoted." And I swerved. And then he rang up a second time and said "You've been promoted again." And I swerved again. He rang up a third time and said "You're managing director." And I went into a tree. And a policeman came up and said "What happened to you?" And I said "I careered off the road."
