After the latest instalment of Game of Thrones (9.00pm, Tyrion plots to strengthen his position as Hand of the King by promising advantageous marriages to three powerful allies, and in Winterfell, Maester Luwin tries to help Bran make sense of his prophetic dreams), the film-maker continues his exploration of British culture by examining the nation's attitudes to romance, and discovers why insults could prove to be the future of flirting. He also canvasses the opinions of comedians Andi Osho, Johnny Vegas and Kurt Braunohler, and introduces music by the Midnight Beast.
