 From the Pickaxe, 2nd Edition, page 11:
	"Everything you manipulate is an object, and the results of those 
manipulations are themselves objects."

Every single thing you use, is derived, in the end from Object, the 
great-grandfather of everything Ruby. At least that is how I've 
understood the Pickaxe in that regard.

On the other hand, I only hack Ruby into my keyboard, and don't hack 
Ruby. ;)
