Fred Metcalf wrote many of David Frost's best lines, he's also anthologised jokes and quotations for Penguin in the past. This collection is fresh, drawing from sources such as Twitter (which justifies a new purchase) and quirky.
I was pleased to discover some writers I'd never heard of before like Sally Poplin, who is quite sharp, and Michael Deacon, who writes sketches for the Daily Telegraph. It was also fun to find many of Boris Johnson's best.
As a speechwriter, I bought the book to add to my armoury of witticisms to relax audiences (as Metcalf points out many speeches fail because of lack of humour). You can't always see the value of a quote until you've tried it out, but these quotations are short and the familiar feedline -punchline structure is there in most of them. One quibble, there is no index of contributors in the back, which is useful when you're trying to find a quotation you half remember.
Still, it will be the first book I turn to in 2013 when I'm struggling for inspiration.
