I think Why's guide is an excellent piece of subversive education.

You're never really sure if you're learning anything and then bang,
right out of the corner of neverseenthatcoming, it hits you, you know
Ruby(ish... kinda... ).  And then you have to wonder, just when was it
that anything started making sense?
