John Cleese's Horrid Dogwhistle

As beloved the film The Monty Python's Holy Grail is to many comedy goers, many fail to realize the horrid dog whistle that is the scene that involves the "Knights who say Ni". In a secret never before listened-to tape, John Cleese admits that the joke was about how pussy his boarding school friends were for refraining themselves from saying (and recoiling upon any utterance) of the word nigger. "I remember after we left Cape Town and seeing the disgusting brown huts, we knew that the limp dick faggots at Cambridge would pressure the end apartheid and by extension the end of our colonies in Africa. We knew it was inevitable but I suppose that we had to make light of the situation somehow."
Once you pay attention, the horrible racism reveals itself horribly. Where the ancient celtic knights who say "nigger" against the anglo-saxon britons on their quest for an item not currently in their possession, you realize the horror of the subtext.
