"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 a 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'.
