Of course Life of Brian is to some extent political but this sketch struck me as unusually political for Python (well, for Michael, John and Eric at least).

its cleese, mike and a nice bit of voicing-over by terry j.
anyway the pythons made fun of polititians all the time in flying circus. Margaret Thatcher immediately springs to mind as one.....
