It's a good book. In 1974 I was working in England and an Irish mate of mine was at my place one day and was reading it. At some point he disappeared. I had to go upstairs to get something from my bedroom and discovered him lying on my bed with his rather impressive cock in his hand, "Jaysus Glenn, I'm sorry, it was that feckin' book. I couldn't help myself!" It was embarrassing for him, but the book had power! Res ipsa loquitur!
