Argumental (working title Whose Side Are You On?) is a British improvised comedy panel game hosted originally by John Sergeant and later Sean Lock, alongside two teams captained by Marcus Brigstocke and Rufus Hound, followed by Robert Webb and Seann Walsh, debating and arguing on various topics with help from various guests. It is made by independent production company Tiger Aspect Productions for Dave and made its debut on 27 October 2008. Series three was commissioned for Dave and four episodes from the second series aired on BBC Two, making it UKTV's most successful commission in terms of reach of audience. Participants The programme was originally chaired by journalist John Sergeant whose post-journalistic career at the time the series began was on the rise due in part to his appearance on the BBC's Strictly Come Dancing. He was joined by team captains Marcus Brigstocke, the host of The Late Edition, and comedian Rufus Hound. Each team captain was accompanied by a guest panellist who have included Jimmy Carr, Sue Perkins, Reginald D. Hunter, Phill Jupitus, Charlie Higson, Johnny Vegas, Lucy Porter, Dara Ó Briain, Sean Lock and Frankie Boyle. From the 2011 series, Sean Lock replaced John Sergeant as presenter, while Seann Walsh and Robert Webb took over as team captains. This coincided with a revamp of the show's set and graphics. Format Each episode comprises a series of rounds in which each team takes its turn debating a variety of topics, whilst also trying to be amusing. Topics have included: 'recycling is a waste of time' and 'the Royal Family serve no purpose'. After each round the team members often make humorous observations about what has just been said, before the studio audience votes for who they thought put forward the best case. Voting is done by holding up a red or blue paddle to vote for the red or blue team respectively. The votes are tallied before the winner of the round is decided. The team that wins the most rounds wins the show. Rounds Each episode normally contains 5 rounds. Sometimes however some episodes contain 4 rounds with 1 round dropped altogether. Classic debate A representative from each team takes their turn to argue for or against a given motion, respectively. After the main arguments have been put forward the teams are invited to discuss the subject further to reinforce their team's argument or attack their opponent's.
