Career: Davies started to get noticed for his comedy as one third of sketch comedy group We Are Klang. His big break came in 2008 when he began playing schoolteacher Mr Gilbert in E4's hugely popular sitcom The Inbetweeners. In 2010, Davies's debut solo stand-up show, Firing Cheeseballs at a Dog, was nominated for the prestigious Edinburgh Comedy Award, which led to a sell-out nationwide tour. His second solo tour, The Back of My Mum's Head, was another sell-out national tour. He plays the lead role in popular Channel 4 sitcom Man Down, a series he also co-writes.

Career: Ryan moved to the UK to work for a fashion magazine and began finding stand-up work. She is now a regular guest on Mock the Week, 8 Out of 10 Cats and Never Mind the Buzzcocks. She has also starred in the sitcoms Campus, Episodes and Badults.

Career: Osman has worked behind the scenes as an executive producer on a number of TV programmes, including Deal or No Deal, 8 Out of 10 Cats, and 10 O'Clock Live. As the UK creative director of TV production company Endemol, he pitched the quiz Pointless to the BBC. As a way of explaining the rules, he played the co-host during a run-through. He was asked to do the role for real when the show was commissioned. Pointless started on BBC Two in 2009 and was an immediate hit. It quickly made the switch to BBC One. Since being in the spotlight on Pointless, he has made guest appearances on QI, Have I Got News for You and Would I Lie to You? He also guest presented an episode of The One Show alongside Alex Jones.

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.
