Claudia: The scariest thing I do in David's shows? Definitely the guillotine. There I am, strapped into it with my hands tied behind my back, unable to move, and all I can do is stare down into the basket and wait. That always makes me a bit nervous. But the scariest part is when I feel it start to shake as the blade drops, then feel the blade go through my neck, and then see the basket apparently jump up at me as my head drops into it - That's the bit that I've still not got used to yet. Then again, is being beheaded something you should get used to? Compared to that, being sawed in half is easy!
