From Dirty Feed, a magnificent, thoroughly documented deep dive into the history of one of the greatest punchlines in the history of British television:
Sad to contemplate that none of the three actors involved is still with us, but what a memorial to their work together on a programme that shaped a generation's view of how government worked.
Fascinating to see the history of that joke pieced together, and the very different version of the punchline used in earlier incarnations.
