Hmmm.... 9,161,923 square kilometres, 307,308,000 people.... I'm sure some of them somewhere in that vast nation of English speakers probably use that expression at some time or other...
Anyway, back to schwanzlis: I often get into trouble for mispronouncing the name of the artificial island in the Limmat where one can spend long summer evenings enjoying a cold beer and watching old people dancing. Apparently, it
isn't called the
Bauschwanzli at all...
