“Of course it's juggling,” the man in motley was saying [...] “You know what your problem is, Sir Grenall? You've been seduced by the lure of spectacle. Sure, I could juggle three or four balls and use two hands, and that would be very impressive, but then what would I do after that? Five balls? Three hands? You see how it goes? Now me, I'm an artist, trying to recapture the original purity of the art form. This” - the man nodded at the ball he tossing up and down - “this is the essence of juggling.”

“Those who try to juggle wisdom, power and greed, drop one of the balls, every time.”—Zarost”

“Vimes felt his hand begin to move of its own accord--And stopped. Red rage froze.There was The Beast, all around him. And that's all it was. A beast. Useful, but still a beast. You could hold it on a chain, and make it dance, and juggle balls. It didn't think. It was dumb. What you were, what you were, was not The Beast.”
