Oblivious (rendered on screen as Obliviou$) is a hidden camera comedy game show based on the British format by Tiger Aspect Productions and Mast Media of the same name.
Host Regan Burns would take a camera crew with him and ask unsuspecting people trivia questions, while playing some sort of role.
At the start of the show, and before and after commercial breaks, Burns would walk up next to someone on the street and ask a single question for $20, before saying "We'll be right back" or a similar phrase.
Once per episode, Burns would give the unsuspecting contestant a chance at up to $500 more (this was called the Lightning Round), if s/he would take on the role of quizmaster.
He would walk them through it using a hidden camera and a headset microphone out of view, and for every question that the next contestant got right, the first player got $100.
