Visual aids Team members try to argue over a topic while incorporating pictures from a slideshow that they have never seen before into their case. Flip-flop Each team is given a different topic to argue about in this round. The team representative must argue for the motion until a buzzer sounds at which point they must argue against the motion. The contestant continues to alternate between for and against until the end of round buzzer is sounded. This round does not appear in every episode. That's a Brilliant Idea Introduced in series 3, representatives from each team take turns being given a typically nonsensical, illogical or outrageous statement, and have to argue a convincing case for that statement being a good thing, starting each argument with the words "That's a brilliant idea.". Popular culture round In series 1, this round was similar to the 'classic debate' round except the topic involves a famous person or celebrity. The person being debated was represented by a life sized cut-out placed in the centre of the performance stage. Past celebrities have included Piers Morgan, Victoria Beckham, Amy Winehouse, Wayne and Coleen Rooney, Simon Cowell and Jeremy Kyle. Since series 2, this round has not always featured cardboard cut-outs; in some episodes, real-life people (e.g. a body builder) come on stage instead. Final picture round This round doesn't involve any arguing per person, alternatively contestants are shown pictures for which they must invent a motion to suit. Unlike the other rounds, both teams remain seated throughout. Like the flip-flop round, this round has not always been included. The audience still votes red or blue.
