Often these days, you'll see well-known people say 'AMA' on Twitter because they're bored on a train or something. It means 'ask me anything'. Mark Watson has never done this, because he never is bored on a train, because his brain is horrendously overactive. But what would happen if you did it in a physical environment? A show shaped by your curiosity. Bring a question. NB if questions run out Mark will, instead, ask them to the audience. And he is pretty nosy.
