A History of Clichés

Another book on my wishlist:
The Cat’s Pyjamas: The Penguin Book of Clichés by Julia Cresswell
The book is exactly what it says it is: a book which discusses the origins of clichés.
And as for the title, according to Urban Dictionary, cat’s pyjamas is ‘1920s lingo’ used to describe someone or something who is the best. It goes on to say that it usually ‘indicated stylishness or innovation since pyjamas were a relatively new fashion in the 1920s. The term ‘cat’ was beginning to be used as a term to describe the out going and unconventional jazz-age flappers’.
