Why's Guide to Ruby

As you all know I've been learning Ruby recently, and I've been looking around for good resources on the web. Steve has been a good help, he introduced me to the wild side of coding, a fellow called Why the Lucky Stiff. He's an odd chap who's written a guide to the Ruby language that has cartoon strips in it (!), you can check it out here: http://poignantguide.net/ruby/
It really is quite entertaining, he seems to be smoking more than just tobacco in his pipe.
