It has been a particularly good day for the travelling salesman and he needs just one more sale to get his commission. He knocks at the door of Little Johnny's house. Johnny appears at the door, steps out, looks around furtively and then whispers, 'What do you want?' The salesman looks at Johnny and says, 'Is your mummy in?' 'Yes but she's very busy,' Johnny whispers. 'Okay,' says the guy, 'what about your dad, can I have quick word with him?' 'Nope,' whispers Johnny, 'he's busy too.' The salesman pauses but he is desparate for that one last sale. 'What about your brothers and sisters ... do you have any?' 'Yes,' whispers Johnny, 'but they are all very busy too.' 'Grandparents?' 'Nope, tied up as well.' 'Are there any other adults in the house I can speak to?' the guy asks exasperated. 'Yes,' says Johnny, 'there's the vicar, two fireman and a policeman here at the moment.' 'You mean your whole family, the vicar, two firemen and a policeman are all in the house but they are all too busy to come and talk to me ... what on earth are they all doing?' 'Looking for me,' says Little Johnny.
