Picture a 34-year-old man visiting the zoo on his own, standing and sniggering while snapping photos of a monkey intensely staring at - and sometimes picking bits from - another monkey’s bum. You might think that would be embarrassing. And you’d be right.

Except it was totally worth it. Not only for this, slightly creepy photo, but for the series of supremely imaginative explanations the parents of various toddlers were having to give to their overly inquisitive children as they ushered them quickly past.

I love the zoo.
