Aren't most Swiss German? If so, then they're hypocrites. Or do the Swiss right just dislike all foreigners?
In before Lewis makes a joke along the lines of, "Whatever they speak in Switzerland, it sure ain't German!"
Swiss accents are funny.
Swiss Germans speak two languages. One that until fairly recently completely dominated airwaves, parliament, education, etc (and still dominates education, just not completely anymore) and which they mistake for High German and some Germans mistake for Swiss German (because it's what they'll speak to Germany Germans). It's close enough to High German to be almost completely intelligible even to the untrained ear. Certainly closer to High German than to Swiss German.
The other is Swiss German, which is almost as divergent from German as Dutch, which means I get the broad gist of what is being said from the third sentence on or so, if people are speaking clearly and slowly without any disrupting background noises.
