Bear is just getting ready for his winter's hibernation when there is a "Knock Knock" at the door. As one after another of his friends arrive, each with a knock-knock joke, our ursine character gets more and more irate. Then he realizes that he is being given a "happy hibernation" party, and goes happily off to sleep. When he awakens in the spring, it is then his turn to go knocking...

Children who love knock-knock jokes will enjoy Knock Knock, which pairs an amusing, joke-filled narrative from author Tammi Sauer with colorful, cartoon-style artwork from illustrator Guy Francis. Although there are grouchy bears aplenty in the world of picture-books (think the bear in Goodnight, Already!, or in Ryan Higgins' Mother Bruce), this is the first story I've seen to feature a grouchy bear reacting to knock-knock jokes. Somehow, the combination really tickled my funny bone! Recommended to all young grouches, and to anyone who appreciates knock-knock jokes. ( )
