Children love to be funny and to swap cool jokes. All of the classic joke formats -- jump jokes, knock-knocks, riddles, visual puns, and many more -- are included and grouped by themes that reflect childrens's interests and lives including technology, monsters, aliens, families, school, and silly book, movie, and song titles. Each chapter ends with a "half-joke," so that readers can test their growing skills by making up a punch line. Full-page drawings by Paul Brewer accompany each section, and spot art throughout the book punctuates the jokes with visual humor. The 17 ½ tips at the end of the book help the reader to develop confidence and a personal style of telling jokes. Also included are guidelines for writing funny jokes. Some of the author's favorite lines submitted by readers will be posted on youmustbejoking.net. This collection of over 200 jokes and silly art will appeal to the class clown and stand-up performer in every child.
