You, Octagon and Heptagon creep sideways down the hills and through the meadows, across bridges and through Plexville and Prism City, followed by five miles of neglected spaces and fallow fields, when you finally see a sign. The sign reads:
Welcome to the Museum of Geometry and Shapely Mathematics! Ten vertices to get in.
Don't worry; they mean "vertices" as in geometric currency. It won't cost you or any of your friends your shape. You have V1,000 right now.
