The Oxford Dictionary of Humorous Quotations Ned Sherrin
Now in Oxford Paperbacks, Ned Sherrin's dictionary of quotations is a collection of the sharpest, the wittiest, the wryest and wickedest in quips, put-downs, and one-liners from both humourists (Oscar Wilde, Dorothy Parker, Groucho Marx), and the nouveaux droles, including Stephen Fry, P.J. O'Rourke, Victoria Wood, Bill Bryson, Douglas Adams, Roseanne Barr, Ian Hislop, and Julie Burchill.
