Inside Nature's Giants: Kangaroo 8pm, Channel 4 It seems that the Inside Nature's Giants team are starting to struggle with the self-imposed limits of their show's title. The subject of tonight's dissection, the kangaroo, can certainly grow to a decent size, but it scarcely qualifies as "giant". The leaping marsupials are nevertheless fascinating, and the episode expands into a wider exploration of the enthralling weirdness of Australia's fauna. Simon Watt, accompanied by Charles Darwin's great-great-grandson, heads into the Blue Mountains to meet Australia's peculiar zoo of egg-laying mammals and birds keen on interior decor. Andrew Mueller Dara O Briain: School Of Hard Sums 8pm, Dave A peculiar new show from the Irish funnyman and front of Mock The Week. Based on the assumption that – because he studied maths and theoretical physics at University College, Dublin – he must be quite clever, O Briain attempts to solve questions and conundrums set by Oxford professor Marcus du Sautoy. The puzzles are the kind of things that made you grimace as a child (the quickest route across two rivers) combined with some tomfoolery (how to get the most kisses at a dance). A comedy guest – David O'Doherty this week – acts as a foil to Dara's logical mind; the equivalent of the kid acting up at the back of the class. Martin Skegg The 70s 9pm, BBC2 According to historian Dominic Sandbrook, 21st-century Britain was forged in "a strange and distant place" called the 1970s. It was a time when ordinary Britons yearned for more: more freedom, more opportunities and, long before Thatcher made herself at home in 10 Downing Street, more money. An acutely observed survey of the decade begins with Ted Heath, who, in Sandbrook's reading, saw himself as akin to a dynamic CEO shaking up a fusty family firm when he became prime minister. With mortgage rules relaxed, a property boom followed and a glammed-up nation got it on. Jonathan Wright Scott & Bailey 9pm, ITV1 The crime-fighting pair face a tough test this week as they try to find the killer of saucy Susie Binns by sifting through her impressive back catalogue of lovers. Meanwhile, 90s pop star Sean Maguire wants to marry Rachel, who continues to look less than enthused by the idea. She's suitably horrified when Sean suggests a stepmotherly introduction to Haydn, his eight-year-old son from a previous marriage. Hannah Verdier Game Of Thrones 9pm, Sky Atlantic Game Of Thrones continues to play to its strengths by placing Tyrion at the heart of the action, as he continues to indirectly jostle for control of King's Landing in his new position as King's Hand. There's more Stark action, too, as Bran's prophetic dreams continue and Catelyn makes herself useful by trying to smooth things over with the Baratheons. Rebecca Nicholson Mike Judge's Beavis And Butt-Head 10pm, MTV The 90s cult superstars return for a new series. Don't expect the monosyllabic Texan teenagers to have "matured" in the 14 or so years they've been absent from our TV screens. Instead, the hard rock-obsessed pair remain acerbic in their views on contemporary culture, with reality TV (chiefly MTV's own shows like Jersey Shore and 16 And Pregnant) coming in for their blunt, vaguely postmodern appraisal. Tonight, the pair are envious of how the Twilight vampires get so many girls. Their solution? Try to get bitten by a werewolf (actually a homeless person). John Robinson
