Watch Only Fools and Horses online: Episode 22 Licensed to Drill

The one-off episode was produced by the Maureen Oilfield Consortium as an educational video to be shown in British schools. The character who cons Del is played by Scottish actor Iain Blair. The film does not feature a laugh track unlike most episodes of the show but similarly to several other one-off specials which were made. The character of Grandad, played by Lennard Pearce, wears a new hazel coloured cardigan and his neck scarf and undershirt are uncharacteristically clean and bright looking in this episode. Ironically, as this was his final outing before his death, he also looks much healthier than in previous episodes though this could be the result of toning down the makeup used as the film is not as dependent on lighting techniques as it uses a much higher quality film stock than the one deployed in the television series episodes. This appearance of health may also be helped by the unusual cleanliness of his garments which are always stained and unkempt in his previous appearances. One of Grandad's last significant lines is in response to Del telling him to wake up during the oil film as the film is "exciting". He says "I know. I'm getting excited with my eyes shut." Lennard Pearce's last lines of dialogue in the role of Grandad are in response to Del asking if he thinks he had been conned "Of course not.....He had an honest face. In fact, he reminded me of you Del."
