I know this is years after this has released, but I thought I'd still bother posting in case anyone is interested. Also, this is not to hate on this episode because it was still good despite the inaccuracies.
- Mennonites do not engage in rumsrpinga, that is exclusively an Amish practice.
- The note in question could not possibly have been in Pennsylvania Dutch because PA Dutch is not a written language. There have been some recent efforts by individuals to create a written version for fun, but there is no consensus or any real popularity with any of these.
- More subjectively, it is painfully obvious the "Mennonites" are no kind of Mennonite as their mannerisms, dress, and accents amongst other details are not at all representative of any kind of Mennonite that might speak PA Dutch.
