The scene in question was that when one of the blow up dolls inflates by itself, which causes Del Boy, Rodney, and Uncle Albert to leave the room in a panic.
At the Nag's Head, Denzil tells the Trotters that he took his wife, Corrine, out for the evening the previous Friday to celebrate their anniversary, despite picking up a faulty stock of fifty dolls from a shop in High Wycombe and having to return them to the factory.
At a Chinese takeaway, Denzil overhears a London Plus report which states that the dolls are filled with propane gas, which will explode if exposed to heat, and is suspected to have caused the destruction of the factory.
Back at the Nag's Head, Trigger complains about the tomatoes, and Boycie turns out to be the one who bought the bulk of Del's faulty video recorders.
The Trotters throw the dolls in their van, and Rodney heads off to meet up with Cassandra, leaving Del and Albert to drive down to Dirty Barry's.
Del and Albert arrive at Dirty Barry's shop, only to find out that he has had his licence revoked by the council and sold all his stock.
