"Fatal Extraction" is the twelfth Christmas special episode of the BBC sitcom Only Fools and Horses, first broadcast on 25 December 1993.
With Christmas coming to Peckham, which is suffering from recent riots, Del Boy has been drinking every night at the Nag's Head as well as ending up with a sore tooth.
That night at Nelson Mandela House, the Russian camcorders have arrived, but Rodney discovers that they are too heavy and the video cassettes are too wide for UK VCRs.
The next evening at the Nag's Head, after Albert tells another one of his boring war stories, Del enters, and Rodney berates him for ignoring Raquel.
Later that night, Del returns home drunk from too much champagne, and decides to sing the song "One Voice", which starts a riot between some of the neighbours.
The next morning at the market, while unloading the Russian camcorders, Del spots Beverly, who was in the Nag's Head the previous night, and becomes frightened she may be stalking him.
Del rushes over to the Nag's Head to tell Rodney that Beverly is stalking him, because he believes she is an ex-patient in a psychiatric hospital (Boycie mentioned he had seen her there before when visiting Marlene's brother).
Meanwhile, outside by the new Christmas tree, a group of carol singers sing "Silent Night", and Beverly looks up at the Trotters' flat with a smile, implying that Del was right and she was out for revenge all along for cancelling their date.
