The Berenstain Bears and the Excuse Note (Hardcover, Library edition)

As far as Sister Bear is concerned, there’s a whole lot to like about school—her classmates, her teacher, and even the schoolwork. If it weren’t for gym class, things would be perfect. All those jumping jacks and deep knee bends make Sister hot, sweaty, and sore. But when a slight twist of fate gives her the chance to sit on the sidelines, will Sister stretch the truth instead of her arms?
