I remember, in my youth, how dissapointed I waas generally with the Python film ouvre. They seemed to me to miss the mark too often to be truly entertaining.
That said, I think the scene referred to is one of the funnier ones in the film.
This just seems akin to all the bollocks about rewriting parts of books. It's all nonsense. Let it stand, in another 10 years people may possibly see it as visionary. It cerrtainly hits a few nails on the head AFAIC.
