This is real, fast German ..... but here's the thing...
Even though my French is a lot better than my German, when it comes to listening to "real" French and "real" German I'm better ( or perhaps, less bad) with German. And that's because with German I can pretty well make out every word, even if I don't know what all of them mean, but with the French,who tend to run all their words together, and miss most of the ends off as well, I actually understand less . Paradoxical, but mainly true.
Anyhow, let's watch a bit of Heinz shall we .... he's an endearing soul .... and very funny ....
Ernst, by the way, is one of those "Rock" words, that reveal their meaning if you add a letter or two ! ... Rock = Frock ...... Earnest = Ernst
