Film with a Glidecam while riding 
First to hit a whiffleball while idling on one foot?
First to go to all the Unicons.
Helped create several competition events that were held for the first time:
- World Championships (1984; one of many people who made that a reality)
- Gliding (Unicon IV, 1988)
- Coasting (also Unicon IV)
- Offroad racing (later called MUni; Unicon IV)
- Trials (sort of; 1998 MUni Weekend)
- Uphill (offroad) race (1998 USA Convention)
- Downhill (offroad) race (1999 USA Convention)
- Street (2004 MUni Weekend)
Made Sumo a popular but unofficial event at Unicons
Rode my unicycle on the observation deck at the World Trade Center in NYC (surely not the first though)
First to ride both the known biggest, and smallest unicycles: 63/5" wheel, and 13/16" wheel, 1983
First to ride a 29" on the peak forest canal ( it was frozen at the time)
First to ride along the wall of the Llyn Cefni reservoir on anglesey
i think im the first to get a whole announcement dedicated to how i shouldn’t be riding my giraffe on the platform at London Marylebone:D 
The first to get a news bulletin written in the local newspaper targeting myself. It was about bicycling safety rules because I live in a bicyclist neighborhood. it said something like:
“While riding a bicycle, you must keep both hands on the handlebars at all times. This includes unicycles.”
Sometimes I wonder what goes through people’s heads. I have no handlebars.
