This is so funny…but I’m from Canada and what you refer to as “Fortune Teller”, we refer to as “Cootie Catchers”. I’m almost 40 and we played with them as kids and now my 2 daughters and their friends use them. They operate the same way as your fortune tellers and we also used a method by which you choose colours and numbers to arrive at your “fortune”. We write silly fortunes in them about boys, about having stinky feet, etc, etc. I have no idea where the name Cootie Catchers originated.
