Every occasion except reviews. I looked.
I love quote books. There is an amazing amount of wisdom contained in small phrases, and quote books are the kind of books that you can just turn to any page and get something funny, interesting, profound, or quite possibly all three.
And a quote book compiled by one of the guys who wrote Blackadder - where can you go wrong?
Um, I guess you can go wrong, but they didn't. Yay them! This book is divided up alphabetically by topic, like love, drinking, women, etc. There is an index at the end of "quotees" just in case you knew that Charles Kuralt had said something about Highways, but you can't remember what it was. ("Thanks to the Interstate Highway System, it is now possible to travel from coast to coast without seeing anything.")
Oddly, there are four quotes in the potatoes section, but no pie section. If you want the Carl Sagan pie quote, you have to look in the index. ("If you want to make an apple pie from scratch, you must first create the universe.")
There's a Homer Simpson quote about Clown College.
Besides the quotes, some of the "quotees" even have a little explanation after their quote. The Charles Kuralt quote above mentions his "On the Road" series on CBS.
This is a fun book to have handy. I highly recommend it.
