Salesman: Hello Sir. I would like to demonstrate to you the greatest invention ever. May I come in?
Man: Yes ... come in ...
Salesman: I would like to show you the latest invention which will revolutionise the world. This vacuum cleaner does not use any electricity at all. And no batteries either. What do you think of that?
Salesman: For a moment I thought you'd say it sucks!
Man: No ... it's neat!
Salesman: Indeed it is neat. And it will make your whole house neat. And it will save you hundreds of dollars in electricity. Because it does not use electricity, or batteries which you have to re-charge. And what's more ... no electricity means it will help save the planet because you are not using any power at all. So you save money and you save the planet. What do you say now?
Salesman: Yes ... double neat indeed. Let me show you how it works. You are married are you?
Salesman: Good ... because this vacuum cleaner requires the help of one's spouse to make it work. We call it Perfect Partnership. Husband and wife working in harmony together. Or indeed any couple, friends living together, or any two or more people working in harmony together to save money and to save the planet at the same time. Shall I show you how it works?
Man: Yes please.
Salesman: I'll pretend to be your wife and I will operate this hand pump here. As I pump up and down up and down ... see how I do it ... you will move the vacuum cleaner head backwards and forwards and suck all the dirt from the carpet. Let's try it ... what do you think?
Man: Neat ... it's great ...
Salesman: You bet it's neat ... it picks up all the dirt ingrained deep in the fibres of the carpet. And no electricity whatsoever. All it needs is me to pump up and down and you to suck in all that nasty dirt.
Man: It missed a bit over there.
Salesman: Yes it does every now and then. But you can always pick the bits it missed with your hand and put them in the trash bin. I bet you can't guess how much this new invention costs!
Man: I have no idea!
Salesman: Well, for you ... as an introductory offer seeing you are the first house I called on in your area ... this latest modern invention is yours for only $100. Do you like it?
Man: I do ... I think ...
Salesman: I'll tell you what ... I am authorised to make you a special offer. If I leave this vacuum cleaner with you for a month, and you demonstrate it to all your neighbours, family and friends ... for every vacuum cleaner you sell I'll give you $10. You only need to sell 10 in a month and I'll give you this cleaner for free instead. What do you say to that?
Salesman: Neat indeed ... now let me get your John Hancock signature on this contract here ... By the way, what will you do with your existing electric vacuum cleaner?
Man: I'll throw it away. It's only gathering dust!
