why's (poignant) Guide to Ruby

why's (poignant) Guide to Ruby, sometimes called w(p)GtR or just "the poignant guide", is an introductory book to the Ruby programming language,[1] written by why the lucky stiff.

Many motifs have become inside jokes in the Ruby community, such as references to the words "chunky bacon".

The book includes many characters which have become popular as well, particularly the cartoon foxes and Trady Blix, a large black feline friend of why's, who acts as a guide to the foxes (and occasionally teaches them some Ruby).

Chapter three was reprinted in The Best Software Writing I: Selected and Introduced by Joel Spolsky (Apress, 2005).
