Fran leaves for the weekend to go to her friend Becky's hen party while Bernard and Manny, inspired by their latest children's-book event, decide to write and illustrate a book for children. Bernard's first effort comes to over 1,000 pages, covers Joseph Stalin, a lens grinder, a broken marriage, and a truth-seeking journalist – a bit complex for kids. The subsequent masterpiece, The Elephant and the Balloon, could bring them international fame—and all its problems. Meanwhile, Fran's hen party is a disaster: the booze starts flowing, and a game of truth stirs up tears and recriminations. Guest stars: Lucy Davis as Becky, Olivia Colman as Tanya, Charlie Hicks as Timmy and, Oliver Golding as Young Customer.
