Inside Culture BBC2, 7.30pm

Mary Beard begins a new series of the cultural discussion show by looking at laughter, with a little help from comedian and writer David Baddiel (left), who talks about how it can bond people, but can also be a sign of cruelty and transgression. Plus, Beard visits artist Maggi Hambling, who tries to capture laughter on canvas, and talks to neuroscientist Sophie Scott and another comic, Shaparak Khorsandi, about what happens when we giggle. ★★★★★
