Juggling might be the most fun useless skill to have. People who can't juggle see it as some impossible trick, while those who have mastered the skill can see through the flying orb planets as some easy maths problem.
Just check out the view from a juggler's perspective. For me, a non-juggler, it looks like the ball is going to smack me in the face. For the guy in the video? It ain't no thang.
