janie (USA: AK) (2008/07/26): What happens when your teacher gets sick and has to leave for the day? You get a substitute. And how do you sink a sub? you have to make them cry. SO a bet is made involving the 'Spit-Pit' and it's boys against the girls. And the sub? Well maybe by the end of the book they are not quite what the kids expected. Very cute. Oh and it involves a 4th grade class room.
