Hit and Run - S2-E5
Question: Towards the end of this episode the squad car has to double park so Regan can use a phone box, as Regan gets out of the car a van has to drive round the squad car and the driver sounds the horn, Regan gesticulates and shouts "up yours" at the van driver. I wonder if this was scripted or was a random moment and John Thaw was ad-libbing?
Answer: Scripted.
