MTV's "The Substitute": America's first ambush-style game show where a substitute teacher takes over a normal classroom to test students on things they should and shouldn't know for the chance to win $5,000. / The game begins when our "substitute teacher" walks into the classroom and shocks the unsuspecting students by telling them he's not like any other substitute... he's there to host a game they're the contestants -- and it starts right now! / The students will compete against each other in a series of trivia and interactive challenges, which will turn their classroom upside down, give them the chance to win fun prizes and ultimately the grand prize of $5,000.
