Book excerpt: A recent poll conducted by Ipsos Reid for the Comedy Network showed that 99 per cent of Canadians believe laughter is good for the health. That only confirms what we suspected all along - The Penguin Book of Jokes is the ultimate feel-good book of the year! There has long been a rumour going around that Canadians aren't funny. Well, John Robert Columbo has assembled a comprehensive collection of Canadian humour that is sure to dispel this rumour for once and for all. At once scandalous, subversive and hilarious, The Penguin Book of Canadian Jokes includes a wide range of riddles, puns, and side-splitting anecdotes from the world of history, politics and culture (er, hockey). All those jokes that you share around the water cooler, that delight you in your morning e-mail and that crack you up over your morning paper - they're all here, together for the first time in one handy and hilarious volume.
