I've seen this book meme going around recently, notably on Anthony Kennerson and Belledame's site. Using a series of Google Blog searches, the meme seems to have arisen on Livejournal about 2 years ago. Anyway, here goes, with some tweaks of my own:
1) Pick up the book that you are nearest to with 123 or more pages. (According to early versions: Don't search around and look for the "coolest" book you can find. Do what's actually next to you.)
2) Turn to page 123.
3) Locate the fifth full sentence in that page.
4) Copy that and the next two sentences that follow.
5) Tag three more bloggers to do the same.
Gills usually adnate but sometimes adnexed or slightly decurrent, close to crowded (120-150 reaching the stalk), soft, slightly waxy; white at first but soon flushed pink and developing purple-red to vinaceous stains in age. Stalk 3-10 cm long, 1.5-3.5 cm thick, usually rather stout; solid, dry, smooth, equal or tapered below; white, soon stained or streaked pink to reddish or vinaceous. Veil absent.
(Description of Hygrophorus russula from "Mushrooms Demystified" by David Arora.)
OK, so not very elegant. I'll cheat and throw in the book right underneath:
It was all tiny houses, miniture chapels over each grave. Sabina could not understand why the dead would want to have imitation palaces built over them. The cemetary was vanity transmogrified into stone.
(From "The Unbearable Lightness of Being" by Milan Kundera. Which reminds me that I need to take it back to the library.)
For my three tags, I pick Audacia Ray, Amber Rhea, and Greta Christina. But consider the tagging "open", just leave a link in the comments box if you've self-tagged after reading this.
