The Unicycle. It isnt a practical device, and it is more trouble than its worth when one could just ride a bicycle. What practical purpose was the unicycle intended for, considering it was not for transportation and DEFINITELY not for fun (that thing is a bitch and a half to ride, i swear).
After you get used to riding a unicycle, it's actually much more convenient and easy to use than a bicycle, and leaves both hands free...it's also kind of fun. Just doesn't go as fast. I think of it as a precursor to the Segue. Unicycles should come back into style so people can text as they bike. :)
