British actor Sir David Jason has reprised his most famous role - as market trader Derek 'Del Boy' Trotter in hit sitcom Only Fools and Horses - to promote a phone-in competition on U.K. Tv show This Morning. Jason, who has not played the character since the comedy ended in 2003, employed Trotter's famous catchphrases as he told viewers, "This time next week you could be a quarter of a millionaire. You know it makes sense."
