In these two books, he tells a broad variety of jokes—from puns to ethnic, from limericks to anecdotes. The latter book, it may be noted, is replete with sexually-explicit humor.What makes these books surpass many of their contemporaries is that heexplainswhat is funny to the jokes, and gives tips on how to tell them. He talks about the effect of the jokes on different audiences, and the personal touches that you can add to make the joke your own.Treasury of Humoris unique in that in addition to being a working joke book, it is a treatise on the theory of humor, propounding Asimov's theory that the essence of humor is an abrupt, jarring change in emphasis and/or point of view, moving from the crucial to the trivial, and/or from the sublime to the ridiculous.
