This title comes from a cockney saying "only fools and horses work," and is also included in the theme tune. It was previously used by writer John Sullivan as the title of an episode of his earlier London-set comedy, "Citizen Smith." It sums up the subject matter of this comedy series, which features the scams and dodges of shady entrepreneur Derek (Del boy) Trotter and his inept younger brother Rodney. Played by David Jason and Nicholas Lyndhurst, the pair first appeared in 1981, and for many their series summed up the ethos of Thatcher's Britain. Del, with his pretentious tastes (favourite drink: Drambuie and grapefruit juice) and belief in the power of money, is a parody of the "Yuppie" generation. He flaunts his non-existent wealth at every opportunity: "Sorry, wanted on the mobile," is a frequent aside, as he flourishes an early mobile phone. In one episode, a "miracle" is created when a statue of the Virgin Mary is apparently weeping in the local church; much fundraising later, it emerges that the "tears" are in fact caused by Del's theft of the lead from the church roof.
