I don’t speak any German, but I didn’t have any trouble understanding this message, which appeared when I was trying to reach a page on a German site:

Dokument nicht gefunden

I like languages which are so close to English you can translate them without knowing any words. Once, at school, we were asked to translate a page of Dutch, and of course we all panicked because we didn’t know any Dutch, and then we read the page and it was full of sentences like “Santa Claus ist un olden menn met un lang witt bard”.
