Vic - it's not really a game show. Just the host asking interesting questions and the panelists are awarded points not only for the correct answer, but also for interesting ones, regardless of whether they are correct or even relate to the original question, while points are deducted for "answers which are not only wrong, but pathetically obvious"
First series was on topics beginning with 'A' and the subsequent series working their way through the alphabet and the current series is topics beginning with the letter 'S'.
