ea. vol: illus. by Joan Hanson. un paged. (Make Me Laugh! Joke Bks.). CIP. Lerner. Mar. 1986. PLB $5.95. Gr 2-6Children delight in the kind of word play used here, and while most adults would consider these jokes ``groaners,'' youngsters will find these books, each on a single subject, enter taining. Some pages contain three jokes and answers, others just one riddle with a corresponding illustration. Because the answer appears right after each joke, it is impossible for readers to try to solve the riddles independently. Sim ple line drawings, with just a slight dash of one color, adequately decorate the text.Susan H. Williamson, Saltsburg Junior/Senior High School, Pa.
