Us Brits can criticize the London 2012 Olympic Games all we want, but Americans can jolly well keep their opinions to themselves. I kid.

This video shows what happens when Republican Presidential candidate Mitt Romney visited London on the eve of the Olympic Games… and promptly put his foot in it by doubting how well it’s all going to go.

It was all smiles a little later at Downing Street though, probably because PM David Cameron hasn’t got the balls to tell the possible next U.S. President to shut the hell up.

In many ways Romney and Cameron deserve each other. They share many of the same policies – certainly the British Conservatives have more in common with the Republicans than the Democrats – plus they both come across like fake automatons.
