Steve brings his fun-loving dog, Mike, to school for show & tell. Mike can do all sorts of tricks. On this day, Steve wishes he didn't teach Mike how to turn a door knob! When Mike opens the classroom door and runs into the hallway, he gets into all sorts of mischief. Steve has to search the whole school for Mike but keeps walking past him without seeing him because Mike appears incognito as he is disguised as a janitor, a chef, a teacher, a nurse, a parent, and a gym coach. Eventually, Steve finds Mike as he gets excited and blows his cover. This silly story appeals to the beginner-reader.
