i ride a unicycle.
[{"role": "system", "content": "A unicycle is a vehicle that touches the ground with only one wheel. The most common variation has a frame with a saddle, and has a pedal-driven direct drive. A two speed hub is commercially available for faster uncycling. Unicycling is practiced professionally in circuses, by street performers, in festivals, and as a hobby. Unicycles have also been used to create new sports such as unicycle hockey. In recent years, unicycles have also been used in activities similar to mountain biking or trials. US patents for single-wheeled 'velocipedes' were published in 1869 by Frederick Myers and in 1881 by Battista Scuri. Unicycle design has developed since the Penny Farthing and later the advent of the first unicycle into many variations including: the seatless unicycle (\"ultimate wheel\") and the tall (\"giraffe\") unicycle. During the late 1980s some extreme sportsmen took an interest in the unicycle and modified unicycles to enable them to engage in off-road or mountain unicycling, trials unicycling and street unicycling. Bicycles, tricycles and quadracycles share (with minor variations) several basic parts including wheels, pedals, cranks, forks, and the saddle with unicycles. Without a rider, unicycles lack stability \u2013 however, a proficient unicyclist is usually more stable than a similarly proficient rider on a bicycle as the wheel is not constrained by the linear axis of a frame.\n"}, {"role": "assistant", "content": "Have you ever ridden a unicycle?  It takes great balance to ride it since there is only one wheel that touches the ground."}, {"role": "user", "content": "I have not. I do not have good balance even when walking so I can't imagine trying to ride a unicycle!"}, {"role": "assistant", "content": "I understand.  I think the unicycle is great.  In fact, they have recently started to be used to create different sports like unicycle hockey!  "}, {"role": "user", "content": "That sounds really interesting! It would be fun to watch people trying to play sports on unicycles!"}, {"role": "assistant", "content": "Yes.  The unicycle hockey is just like roller hockey, but, obviously, the players have to ride on unicycles.  "}, {"role": "user", "content": "Hockey in general is hard to play. I can only imagine while trying to maintain balance!"}, {"role": "assistant", "content": "Think about this: in recent years, unicycles have also been used in activities like mountain biking.  Again, mountain biking itself is difficult enough on a bicycle - now try it on one wheel.  Amazing.  I could never do that.  "}, {"role": "user", "content": "That is actually mind blowing. You would think people would be scared for their safety!"}, {"role": "assistant", "content": "The main attraction of the unicycle is among circuses and street performers.  It is an amazing talent that few seem to have.  It must take a lot of practice."}, {"role": "user", "content": "Yea it must. I've only seen unicycles being used at the circus. Its a fun attraction to watch."}]
