Here is my 0.5 seconds of television fame. We were in the audience for a recording of Pointless back in December, which was finally broadcast yesterday. It's currently available on iPlayer
here. The's an audience shot at about 1 min 22s and if you look very closely you can see me in the top right corner. So yes, not exactly worldwide fame but it seems appropriate that my one TV appearance was applauding Richard Osman. ;)
It was fun to be there though, and very interesting to compare the studio version with the edited broadcast.
