Doctor in the House S07E03 - It's the Thought That Counts

To celebrate Sir Geoffrey's twenty years as a professor of surgery, Dick and Duncan decide to buy him a present to celebrate the event, but the other doctors are not keen as they have had recent run-ins with the great man. Dick eventually buys him a tape recorder but it has a mind of its own and accidentally begins recording - a conversation the doctors are having in which they all criticize Sir Geoffrey.
