The Goods have an entirely self-made Christmas (except for the balloons), while the Leadbetters order theirs from a department store. When there's a hiccup in the delivery, the Leadbetters are invited round to the Goods for some homemade food, drink and entertainment.

Tom worries that they haven't made provision for their old age, when they'll be too infirm to follow their self-sufficient lifestyle. Concerned about their old age, the Leadbetters take out a 14th life policy on Jerry, and take up keep-fit. When Tom boasts that his digging and gardening keeps him fitter than Jerry's jogging and rowing machine, they end up having a long-distance race.

The programme explores the enduring appeal of the classic sitcom. With contributions from, amongst others, Richard Briers, Penelope Keith, Monty Don, Brian Sewell and John O'Farrell, All About The Good Life goes behind the scenes and reveals all you ever wanted to know about the series from choosing outfits for Margo to the iconic title sequence.
