In We Need Answers, two celebrity guests take part in a knock-about quiz to find out which one of them is the smartest, the funniest, and the best at surreal physical challenges.

Led by Mark Watson, Tim Key and Alex Horne, and adapted from their award-winning Edinburgh show, all of the questions asked come from the AQA text-messaging service.

The rules are simple - contestants must match their answer to the one given by the text answering service. Questions can range from how many gerbils would have to be stacked on top of each other to reach the Moon to what night of the week is "curry night" at the Red Lion in Stockport.

Mark Watson is the main host, Tim Key poses the questions from an under-sized chair, and Alex Horne serves up the graphics and sounds.

A 13 part second series is now on TV. BBC Four boss Richard Klein says: "I am delighted that We Need Answers is back. The show is a smart way of playing with the whole entertainment quiz genre, and Mark, Alex and Tim are an anarchic but genuinely funny team on the show (even if they still don't quite understand the questions)."
