Leonid Brezhnev pays a state visit to France and he's given a VIP guided tour of Paris. He's conducted round the splendours of the Élysée Palace, but remains as stony-faced as ever. He's shown the masterpieces of the Louvre, but the curators fail to get any reaction out of him. He's taken to the Arc de Triomphe, but displays not the slightest interest. Eventually, the official motorcade drives him to the foot of the Eiffel Tower, where Brezhnev finally stares up in amazement and astonishment. He turns to his French hosts and asks in bewilderment: "But, Paris is a city of 9 million people... surely you need more than one watchtower?"
