Career: Carr began performing on the stand-up circuit, doing up to 300 shows a year for three years, before taking his act to the Edinburgh festival in 2002. This brought him to the attention of TV bosses, and before long he was presenting series such as Your Face or Mine and Distraction. Since then, he's rarely been off TVscreens, hosting the first run of the Friday Night Project, 8 Out of 10 Cats and numerous Channel 4 list shows. He's also made a move into acting, appearing in Alien Autopsy, Confetti, Stormbreaker and Telstar. He is one of Britain's busiest comics and his DVDs are big sellers.

Career: Riley's big break came in 2008 when she was chosen from more than 1,000 applicants to replace Carol Vorderman on Countdown. She presented her first show alongside Jeff Stelling in January 2009, and reached her 1,000th episode in June 2013. Away from the numbers and letters on Countdown, she began co-hosting The Gadget Show alongside Jason Bradbury in June 2013. She was a contestant on Strictly Come Dancing in 2013 and was the fifth celebrity to be eliminated.

Career: Dyer's first film was 1999's Human Traffic and he followed this up with roles in a number of low-budget movies, including Borstal Boy (2000), High Heels and Low Lifes (2001), Mean Machine (2001), The Football Factory (2004), Adulthood (2008) and Vendetta (2013). Dyer had a lead role in Run for Your Wife (2013), which was savaged by film critics and only took £602 during its opening weekend. He has also appeared in a number of stage productions, including Celebration and No Man's Land, and has presented documentaries about football and hardmen. In 2013, he joined the cast of EastEnders as Mick Carter.

Career: In 2003, Richardson won his heat of the BBC New Talent Comedy Search, and a year later did well in the Laughing Horse New Act of the Year competition and J20 Last Laugh Comedy Search. Encouraged by these successes and kind words from Jasper Carrott and Dave Spikey for a performance at the Criterion Theatre in London, his confidence grew. More stand-up followed, including appearances at the Edinburgh Fringe Festival. He went on to feature on numerous radio shows before moving into TV. Richardson appeared on Never Mind the Buzzcocks and Have I Got News For You before becoming a team captain on 8 Out of 10 Cats. He's since published his first book, It's Not Me, It's You! and taken part in various documentaries.

Career: Conaty stars in the BBC's hidden camera series Impractical Jokers and she has appeared as a guest on a number of panel shows, including Have I Got News for You, 8 Out of 10 Cats and Never Mind the Buzzcocks. In 2013, she began playing Jo in Channel 4 sitcom Man Down.
