I really enjoy watching a gifted expert do their job, and it almost doesn't matter what their job is: if they're truly an expert, it's cool to watch. Then there's jugglers: they're kind of nuts already, but really gifted jugglers boggle my mind. Here are a few particularly impressive ones; one juggles the traditional 3 balls, but with a serious twist; the second juggles seven (I know bouncing is easier than in the air, but dang!), and the last guy is just a kid, and he juggles with his feet. Dang.
