People actually say stuff like that? I mean, yes of course do Germans and Austrians make fun of each other and are rather competitive (especially when it has to do with sports, but I think that's quite normal between neighbour-countries), but the language-thing is news to me and it's also pretty stupid since there are hardly any people in Germany who speak German completely without any bits of dialect. Maybe it's because I grew up watching a lot of Austrian tv, but I prefer some of the Austrian dialects over lots of the German ones.
