"Sad times are these when passing ruffians can say 'Ni!' to old ladies."
Roger
Roger the Shrubber is a character in the film Monty Python and the Holy Grail, portrayed by Eric Idle. He was a man who arranged, designed and sold shrubberies. When King Arthur and Sir Bedevere encountered the dreaded Knights who say Ni, they were tasked to find a shrubbery. Arriving at a nearby town, they demanded an old woman to tell them where they could buy a shrubbery. When she refused, they said "Ni!" several times to her. Roger rode up disapprovingly, then introduced himself as a shrubber. Bedevere absentmindedly started saying "Ni!" to him but King Arthur held him back and purchased one of Roger's shrubberies for the knights.
