I can't believe there isn't already a JB thread... I'm in the middle of Dopeland at the moment - its great reading about things and places you personally know! It's a pretty funny read and quite informative too. It's not the grower's companion or anything, but more of an insight into Australian pothead culture. Best airport bookstore buy ever! I plan to read Felafal next. I enjoyed the movie, but have heard that the book is much much better!
He Died With A Felafel In His Hand is one of the funniest books I've ever read! And all the stories in it are true!
