Jtown's most popular attraction. Such an amazing unicyclist his sets go for not 1, not 2, but 3 whole hours. Rides around with a little monkey attached to a chain and yells "WILD MONKEY" and gets the kids going crazy. May or may not have injured pedestrians. 40% chance he is addicted to heroin (this is Jtown after all). Notable appearances include the 2013 NUC in Butler PA and the 2017 Potatofest in Ebensburg PA. Popular with the players of the online videogame TagPro.
