Stock markets had their worst day in years yesterday as traders were spooked by dramatic falls in China.
In the US, the Dow Jones industrial average fell by 600 points and, naturally, those wanting to be the Republican nominee for the White House have been rational and measured in their response.
Wisconsin governor Scott Walker, something of a moderate in Republican terms, called on Barack Obama to show some "backbone" and call off a planned state visit by his Chinese counterpart Xi Jinping next month (that will show them!).
Mick Huckabee, who flogs God-awful history DVDs in-between even more awful White House bids, said it was time for the Obama administration to "build America's economy, not China's or Mexico's". OK...
When it comes to reasoned responses, however, no one beats the Donald Trump, who told Bill O'Reilly on Fox News's The O'Reilly Factor - truly a meeting of minds - that he agreed to an extent with Walker regarding next month's state visit:
I would not be throwing [President Xi] a dinner. I would get him a McDonald's hamburger and say we've got to get down to work.
Asked to elaborate on his meticulously-planned operation to reassure markets, he clarified:
I would give him probably a double-sized Big Mac.
Watch a clip from the interview below, which is also notable for O'Reilly's awful attempts at pronouncing the Chinese president's name - or even understanding who he is to begin with.
