The Harper's boiler is broken, and it won't be fixed until the end of the week. So Susan, Janey and Kenzo are reduced to wearing their coats indoors. There's still room for some heated debate though - Janey wants Kenzo to go to a private school, but Susan defends the state education system (until she changes her mind).
Ben has been at a boat show, and returns home brandishing a model of his favourite ship. His dream is to buy the full-scale working version and christen it the Salty Susan.
At the surgery, one of Ben's patients spots the model boat. The patient claims to have the 41-foot version, bragging that in six months he'll be sailing around the Azores. Ben can't stand it.
To make things worse, Roger is swanning around with an expensive new watch. When Ben asked how he could afford it, Roger explains that he has a new part-time job selling 'Pyramus' products.
Roger invites him to a Pyramus meeting. It looks and sounds worryingly like pyramid selling - or worse still, some sort of cult. But if it was pyramid selling, would they name the scheme Pyramus? Of course not, think Ben and Susan, and though initially sceptical, they are both won over by the enthusiastic Pyramus crowd and buy a large quantity of domestic chemical products to sell.
When they get home, Ben and Susan are buzzing with energy and spend quite some time feeling self-satisfied, putting Roger and Abi down. Michael is immediately suspicious when he catches them chatting, and quickly realises what is happening. He warns that they've been drawn in to a cult, but they're already too far gone.
The next morning, Ben gets up early and manages to achieve two sales of floor wax to a friendly neighbour before making Susan breakfast, which he presents to her along with a very expensive handbag.
But just as Ben and Susan are feeling pleased with themselves, Roger arrives in a convertible car. Fuelled by jealousy, the Harper elders quadruple their order for Pyramus 'product' - filling the garage and their lounge with merchandise.
Michael estimates that it'll take 32-36 hours before they have sold to all their friends and family, therefore reaching saturation point. Sure enough, the next day Susan and Ben sit in their lounge, surrounded by boxes of merchandise they're unable to sell.
Thankfully, Michael has a plan to get rid of the excess stock (for a small fee, of course) pyramid selling.
With their lounge now full of people as well as boxes, Ben tries his best to sell Pyramus to the crowd. When he realises he's losing them (not that he had them in the first place) he invites Roger to the floor to tell them all how he bought his car. Unfortunately for Ben, the answer wasn't what he was expecting: Roger informs the crowd that he bought the car with money left to him when his aunt died.
To top it all off, the new boiler was made by Pyramus, and inevitably doesn't work. Instead, Ben's model boat is used as firewood.
