Nick Knowles
Biography
Presenter who turns up all over the place, a kind of less boring version of Mark Durden-Smith. He has done all sorts, but outside of quiz shows is best known for the home makeover show DIY SOS. His face was for some years home to the last-known outbreak of designer stubble in Britain, but he got rid of it (the stubble, not the face) just before High Definition came in, a decision for which we can all be thankful.
