One of my all time favorite movies is the Monty Python and the Holy Grail. Growing up, we had a very early pay TV service that played one or two movies per month between 7 and 10pm each night and for a month straight all they seemed to play was that film.
I could quote Python from a very early age and used it to enrage my brother. My parents hated it. In two terrible British accents I would say “There’s he is!”, “What, behind the rabbit?!?!” “It IS the rabbit!” One of my favorite parts of the movie is the Knights Who say Ni.
Should you ever run across the knights and need some tips on exactly what constitutes a quite nice shrubbery, the Haynes manual is what you need. Granted this isn’t an actual manual, it’s more a shirt with a picture of the manual.
Still, you could always just buy the shirt and take a different road on your quest for the cup. You can buy one at ThinkGeek for $19.99(USD).
