And then there was "Windisch" in the area where I grew up. It's a peculiar mixture of Slovenian, Italian and South-Styrian dialect. Only the elders spoke it, so it became re-integrated into German, making it even weirder. "St. Peter am Ottersbach" was pronounced "St. Jupperhui am Zwitscherlbach"

This is amazing. I will never get tired of this. My examples are nothing in comparison.
