Doctor in the House S04E20 - Yellow Fever

Due to a remark made by Duncan in his local Chinese restaurant, a party of Chinese communists comes to visit the hospital. Bingham, in particular, is convinced they are spies come to find how hospital equipment can be used to start wars, so there is panic when they all go missing. In fact they have been admiring the hospital's linear accelerator and put in an order for some for Chinese hospitals. They are then invited to watch an operation, which the paranoid Bingham almost sabotages, but the day ends well. However, it seems that Duncan has also been shooting his mouth off in his local Hungarian restaurant as well.
