Americans have better teeth, but the British have better suits. And the best advertisement for a $50 suit is an American walking down a London street.
Most of these people think that without the USA, we Brits would all be speaking German. Blasphemy. Don't they realise we can't speak foreign languages!
But seriously the idea that the USA beat the NAZIs single handed is ludicrous. You'd think they would have the decency not to bring it up, after the way they deliberately stayed out of the war as long as possible and bankrupted us to get payment for arms and supplies.
