There's a reason why Fox has brought back Are You Smarter Than a 5th Grader? for a summer run this year. Even though reruns of the original series have faded away from cable in recent months, it's still a popular show.
The object of the game is for an adult contestant to win up to a million dollars, kind of like Who Wants to be a Millionaire?, except that the stage is set up like a mini classroom. The children can help, up to a certain point.
Comedian Jeff Foxworthy is the series host, and returns to the franchise tonight after 3 years of American Bible Challenge on GSN. It seems Challenge was cancelled due to the revival of 5th Grader and Foxworthy being unable to do both. Unsurprisingly, there've also been the predictable celebrity episodes, where stars, including Foxworthy's pal and Prilosec pitchman Larry the Cable Guy ("Cars"), played the game.
To give you some idea of the game, here's a sample of the original series:
Jeff does look like a school teacher, doesn't he?
The series lasted two years on Fox the first time, then two more in syndication (2009-11), before fading out, and, as it turns out, taking a lengthy hiatus. Reruns of the syndicated version have aired on cable on CMT, GSN, and Up (formerly the Gospel Music Channel). The new episodes will be available On Demand within 24-48 hours of broadcast (check with your cable system).
