You know the scene: the Pythons riding through the countryside on their faithful invisible steeds, clip-clopping of hooves provided by a lackey clapping coconut shell halves together, in their search for the Holy Grail. They encounter all manner of obstacles and strange characters, from oppressed peasants who object to King Arthur's very existence, to three-headed knights who block their path, to a wizened gatekeeper for whom they must answer three questions, to a killer bunny.
