Rip. Off.

Oh people, are you KIDDING ME? They want to charge TWENTY DOLLARS for the little game we played with a piece of paper, a pen, fingers and our own brain cells?

Wikipedia calls it a paper fortune teller. I've heard it called MASH for Mansion-Apartment-House-Shack, and also Cootie Catcher, but this company sells it as Cahootie.

And if you are buying one, call me, because I will sell you accessories for tag, for hide and seek, and other childhood games that DO NOT NEED PURCHASED ITEMS.
