I can't fault people for not knowing where Luxembourg is, but if you can't get the majors like Germany, France, Spain, etc., you're an idiot.
This actually reminds me of an experience I had in high school. We were tasked with writing an essay on a foreign country we would like to visit and why, citing historical, cultural and personal reasons. We had to read the essays aloud the day they were due. The majority of people wrote about various western European countries and a couple tropical countries. Next up is the class airhead, bleached blonde hair and all. She starts out: "The foreign country I most want to visit is Hawaii." I am astonished, as is most of the class and the teacher. I wouldn't be surprised if she held some sort of political office now.
