"The story goes that a Dublin theatre proprietor by the name of Richard Daly made a bet that he could, within forty-eight hours, make a nonsense word known throughout the city, and that the public would give a meaning to it. After the performance one evening, he gave his staff cards with the word 'quiz' written on them, and told them to write the word on walls around the city. The next day the strange word was the talk of the town, and within a short time it had become part of the language."
