Here, it's performed live at the Hollywood Bowl, California, 1982. Argument is one of my all-time favorite Monty Python sketches. There's something so neatly-polished and gemlike to its circular wordplay, even as it skewers humans (particularly British ones) and their messy and peculiar attempts to interact with one another.
As with so many of the troupe's works, Argument seems to be eternally relevant, calling to mind the tenor of certain blog threads.
Also at Shakes' place.
