While on their quest for the Holy Grail, King Arthur and Sir Bedevere encounter the dreaded Knights Who Say "Ni!", a fearsome group of knights who wield the power of the word "Ni!" to torment passersby. The knights demand a shrubbery as tribute in exchange for safe passage through the forest — and one that not too expensive. After Arthur and Bedevere return with a shrubbery, the Knights Who Say Ni escalate their demands: they want a second shrubbery arranged alongside the first in a pleasing two-level effect, with a path cut down the middle using a herring. Matters are further complicated when the knights reveal they are rebranding themselves as the Knights Who Say "Ekke Ekke Ekke Ekke Ptang Zoo Boing" and can no longer stand to hear the word "it".
