I have a few friends who went to the USA for an exchange student year, and my sister did that, too
All of them wrote back stories from school which were so hilarious...
My sister, in one of her first basic english class hours, the teacher had each student take a test written by another student and correct it.
My sister wrote under the one she got, 'You should try writing full sentences for a start'. She got the advice from the teacher to move on to the advanced english class, because the students in the basic class were just too stupid.
A buddy took a sports magazine from Germany with him, and when he was asked to do a presentation on his home country of Germany, he pulled out the sports paper, which had 'Kaiser' Franz Beckenbauer on it, and told the class that Germany was ruled by the Kaiser, and they all believed this.
The worst part is, that most of the US citizens are so überproud about their country, but they hardly know jack shit.
