Each country can do only one thing

I went into an office at a school where I teach and said hi to the guy at the desk. He was dripping with sweat and in a kind of uniform.
"Been playing soccer?" I asked.
"Yeah. Americans have just baseball, right?"
"No, we've got other sports."
"Like what?"
"Well, American football, of course, Basketball, hockey... and all the other ones like tennis, golf and so on."
"But no soccer, right."
"No, we play soccer."
"Yeah but you must have played baseball as a kid, right?"
"Yeah, but played soccer too. Actually I played soccer in elementary school and baseball in middle school.In high school I played Lacrosse, but that's kind of a minor sport."
"Ah, just as I suspected. You're a baseball player."
"Yeah but I played other sports too. Soccer and hockey are big in my hometown, probably more popular than basball."
"No way! Yeah but America isnt going to the world cup, right?" (It starts next month in Germany)
"No, we're going. I think we're in the top ten."

I wasn't trying to argue with the guy but if he asked me a question, I'd answer it. It kind of fits in the pattern here that countries or people froma country can do only one thing. So if my soccer friend met a Russian drinking a beer he'd short curcuit because we all know that Russians Drink Vodka. Period.
