Bowling for Polygons
A large group of friends and I went bowling. We all got our shoes, went out to our alley and began to look for the balls we would use. Instead of having a rack of bowling balls to choose from, there was a hexagonal tub filled with small geometric objects. The objects were all blue, and a little smaller than a soda can. Thinking nothing of it, we began playing. One by one we each tossed these strange "bowling squares," which obviously didn't roll, down the alley in hopes that we'd all get strikes.
