LOL!! I can do a bit Swiss German, too - I lived at Lake Constance for 2 years.
Don't worry, I am actually one of the approx. 0.001% of Bavarians who can speak a completely accent-free Hochdeutsch
(though only if necessary).
With my parents both being teachers plus coming from very different regions (with vastly different dialects), I was raised in High German and basically learned several Bavarian dialects as my first foreign languages.
You can ask Santy
about my High German - we're RL friends and his German is really excellent (as is Space Ball
's and their dad's!)
