A 10K run? You're going to go on a 10K run? Well then you better run your ass to Finland. Real Americans don't run Ks. To be honest, I'm not particularly fond of running long distances to begin with. Distance runners usually look like vegetarians and soccer players. But if you are going to run more than a few hundred yards, you better run yards and miles, and not meters and kilometers. A K isn't a unit of distance--it's a strikeout, a thousand dollars, or the K in K-Mart. Kilometers are for European communists.
Suggesting we should convert to the metric system is an act of treason. Benedict Arnold loved the metric system. As does Barack Obama. When Obama steps on a scale, it automatically displays his weight in kilograms. Even if it doesn't have a kilogram setting. Scales expose anti-Americans the way mirrors expose vampires--and Obama is the Dracula of America haters.
