The book above is the reason several people in a very quiet secondhand bookshop glowered at me when I cracked up laughing upon seeing its title. It had been a fairly ridiculous day*, and consequently I was in a somewhat skewed good humour, but to be honest I'd probably have ended up giggling like a fool even if I'd been depressed because it's such a beautifully silly example of the old adage that Britain and the US are two countries divided by a common language. Now try reading the wikipedia entry (especially the plot summary) on this book without pissing yrself. I especially like the fact it took 30 years for someone to tell Jack Vance what it meant in Britain and elsewhere, upon which all Wankh references were changed to Wannek.
*For reasons I'm not going into here, except to say that if you believe in synchronicity, or don't believe in random coincidence, it was the sort of day that would have made yr head spin.
