John Cena has been tapped as host for an updated version of “Are You Smarter Than a 5th Grader?” The game show debuted on Fox in 2007 with comedian Jeff Foxworthy as the host and ran through 2009. A syndicated half-hour daily version ran from 2009 to 2011. It also had a brief revival in 2015.
From Wipekedia: Each game is played by a single contestant who earns money incrementally based on a payout ladder by answering simple trivia questions, with the game themed as a school quiz. The game relies on the premise that an adult would not know the information generally taught in elementary grade school, because it is rarely used in adult life by the type of person chosen to be a contestant. Therefore, “Are You Smarter Than a 5th Grader?” is essentially a test to see how much an adult has retained since graduating elementary school.
The show also derives its humor by occasionally displaying the contestant’s educational attainment, implying that in spite of that, they struggle to answer some questions.
