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.

Other game show appearances have come in the likes of The Big Fat Quiz of the Year, Have I Got News for You, QI, and They Think It's All Over.

More stand-up followed, including appearances at the Edinburgh Fringe Festival. He went on to feature on numerous radio shows before moving into TV.
