PICK OF THE DAY Michael Palin In Nigeria

9pm, Channel 5

“Lagos is not for the faint-hearted.” The nicest Python, Michael Palin (left), pays a visit to the bustling (“chaotic”, says Palin’s guide) Nigerian city, home to 25 million people, in his absorbing new travel series. He finds that there’s “a lot of poverty” but also a fair bit of wealth. One guide explains that Lagos has “hustle and bustle”, adding that “Nigerians have a unique sense of wanting to thrive”. She also discusses the country being colonised by the British, and Palin is suitably uncomfortable about it. The 80-year-old then negotiates Nigeria’s “notorious back roads” to Kano in the north, where he meets an Islamic leader, the Emir of Kano.

We join them as young Alan considers whether he should go against his instincts and become a footballer himself.

=== Dinosaur

9pm, BBC Three

“What has London done to you?” Nina (Ashley Storrie), an autistic Glaswegian palaeontologist in her thirties, asks her sister and best pal, Evie. It turns out Evie has become engaged (at the Shard, “it was all disgustingly romantic”) in the capital, which makes Nina livid, especially since Evie has only known her fiancé for six weeks. But the parents are more than happy in this thoroughly charming comedy with some rather tangy dialogue: “He’s arguably the most irritating man alive.”

=== Katharine Hepburn: Call Me Kate
