Stephen Leacock 
Humour as I See It [EPUB ebook] 

"The world’s humour, in its best and greatest sense, is perhaps the highest product of our civilization."Stephen Leacock writes a masterful account of how humour works and of how it very often doesn’t. As well as being remarkably insightful about the various ways in which a joke can fall flat, Humour as I See It is an exceptionally humane testimony from one of the English language’s most gifted humourists.
