Oxford Dictionary of Humorous Quotations
First published in 1995, the Oxford Dictionary of Humorous Quotations is now in its fifth edition and with a new editor in Gyles Brandreth. There is a huge influx of new quotations, many of them from very recent years, as well as new themes.
The entries are organised under themes throughout the dictionary, from Acting (with 36 quotes including Katharine Hepburn’s: Acting is the most minor of gifts… Shirley Temple could do it at four) to Writing (23 quotes including John le Carre’s: The cat sat on the mat’ is not a story. The cat sat on the dog’s mat is a story.)
There are over 240 such themes such as Old Age (John Diefenbaker’s: While there’s snow on the roof, it doesn’t mean the fire has gone out in the furnace) or Children (from Punch: See what she’s doing, and tell her she musn’t).
Just the source for a quote to enhance any speech or piece of writing whatever your subject.
