2.
A quiet but rich town with lots to do and lots to see. Next to a great river and has lots of little things you can do. Everybody knows everybody so dont get into trouble because youll be the talk of the town. Is inside the rich stuffy city of Mequon but Thiensville is a much humbler village than Mequon. A great place to see if vacationing in Wisconsin and my personal suggestion as the best place to live in the world.
Don: Hey lets go to Wisconsin

In Thiensville:
Don + Friend: Too busy doin fun things to talk

3.
The worst town in the continental United States, possibly the world. Know for advertising the existence of a Jimmy Johns Gourmet Sandwich Shop, but not actually having one.
"Did you go to the Jimmy Johns in Thiensville?"
"No, I didn't because it doesn't exist."
"Thats gay."
