"The second US presidential debate was characterised by levels of vitriol never before seen on the US political stage.
But while millions of viewers across the world watched in horror as the Donald Trump and Hillary Clinton bloodied themselves over the Trump tapes, Clinton emails, tax, Syria and Obamacare, others saw the opportunity for humour.
Enter the memes.
The combination of microphones and roaming candidates, aided by the town hall-style of the debate in St Louis, proved fertile ground for imagining an alternate reality – one where Clinton and Trump were serenading each other.
As the debate ground on the #debatesongs hashtag spawned memes of the pair singing along to duets from Frozen, Grease and – probably most memorably – Dirty Dancing."
