Initially I was addressed only the witty title. Then I bought the intensive course of block and Neumann Haskell-intensive course: A compact introduction to functional programming (Xpert.press) - a good book, but too short for an introduction to this very interesting matter. But first I had with reading the online version of Lipovacas "Learn You a Haskell for Great Good!" and started my: This is a gentle and yet to really amusing introduction to functional programming is simply unbeatable! But since I can sit in front of computer not always, just to read a good book, I have ordered it myself and recommend it as first read about Haskell - providing experience in programming with other programming languages and halfway passable English - just recommend.
