I used to juggle all the time. I only managed to juggle 3 or 5 balls, as I found clubs like these to be somewhat more difficult to control. But, I never managed to juggle while riding a unicycle like this guy was doing at the Beaches Easter Parade. My hat's off to him for his skill.
I agree, this is a very cool skill. I always enjoy watching juggling (there's a juggling Wii game I like to do). :)
I also love the other guy's purple outfit particularly the tights! Fun!
