Are You Smarter Than a 5th Grader premiered on Fox in 2007, hosted by comedian Jeff Foxworthy. Adult contestants answered questions taken from elementary school textbooks, often struggling with subjects children learn in first through fifth grade. The format was adapted in many countries and became a widely recognised test of everyday knowledge. Online, its theme music survived as a shorthand for trivia embarrassment, appearing in quiz edits, reaction videos and school themed memes whenever someone misses a question that should have been easy for a ten year old.
