Tom is driving along in his car when his boss calls him on his mobile. 'I'm promoting you to Sales Manager,' he says. Tom is so surprised he almost loses control of the car. A few seconds later the phone rings. It's the boss again, 'Henderson has resigned, I'm promoting you to take his place as Sales Director.' Again Tom is so surprised the car swerves all over the place. Seconds later the phone rings a third time. Again it's the boss. 'Harris has had a heart attack,' he says. 'You're the new Managing Director.' Tom is so astonished he loses control completely and crashes the car into the embankment. Later a policeman asks him what caused the accident. Tom says, 'I careered off the road.'
