Why's (Poignant) Guide to Ruby

I need to learn how to program in Ruby. Specifically I need to learn 'Ruby on Rails'. I need it on the resume. Ruby is a difficult syntax for those ( like me ) used to C syntax. It would take a delicately written piece of genius tutorialship to sink Ruby syntax into my C-thinking brain. And I believe I have found such genius: Why's (Poignant) Guide to Ruby. Words can't do it justice, I have already said too much.
