Sassy and Waldo have been cast in the school play and they couldn't be more excited. They love to play! Only this isn't that kind of play. Sassy and Waldo are good dogs. They will do anything for their boy, Stewart. That includes putting on a trench coat and pretending to be a new student named Salty in his class just to make sure he is happy. But this month Stewart's class is going to put on a play. PLAY! There's nothing that dogs love more than to play. Well, except maybe eating hamburgers, napping, and chasing squirrels. But they're all equal. It's a four-way tie! Sassy and Waldo are in for a big surprise when they learn what a school play really is!
