Interesting fact:

The word “quiz” has a great origin story to it. Legend has it that an Irish man made a bet that he could introduce a new word into the English language in just two days. He wrote the then nonsense word, “quiz,” on pieces of paper and got people to write it on the walls across Dublin. It didn’t take long for the word to be incorporated into everyday life, with the meaning of “test,” as that is what people believed the mysterious word was supposed to be.
