15: Pogo Stick

The Pogo Stick is yet another piece of gnomish athletic equipment that really requires no explanation, as the idiocy of the contraption is self-evident. I bring it up only because technological innovations have created so-called "extreme pogo" -- a lifestyle that I think sensible people should avoid, as it is likely just gnomes having a bit of prankish fun with you (since the only thing dumber than a pogo stick is somebody practicing extreme pogo, like going off the side of a mountain or what-not).
