James agreed, as he got to work: “Tonight, I want to show you some very special skills I learnt in my previous job.” The camera showed a production medic on standby, with Dec realising: “Oh,

this is dangerous!” The marine continued: “In my hand, I’ve got some tags, they're lumbered one to six and I’ll give these a mix-up. Simon, I want you to select one tag - try not to

let anyone else see the tag you choose,” he said, as he handed the props to the judge.  Simon selected the tag and James threw a curveball, pulling out a “razor-sharp dagger,” before giving

further instructions. “I want you to place the dagger underneath one of the bags on the table of the tag you’ve just selected.”
