Another interesting language is (rather, was) "Matten-Englisch", something like Pig-Latin, "because people wanted to communicate in a way the police would not understand": https://en.wikipedia.org/wiki/Mattenenglisch
The dialect of Valais is a lot harder to understand than this. But I guess in normal conversation it's a different case again.
