Mrs. Baxter is no ordinary grandmother In fact, she's down right eccentric Martha Baxter does lots of wacky things like carrying an iron skillet with her everywhere and frying up frog legs in the Biology lab at the high school. The story begins when Mrs. Baxter is summoned to Principal Thompson's office to discuss the pending expulsion of her grandson, Norman, who has gotten himself into a bit of trouble. After the meeting, Martha does what any loving grandmother would do--she becomes a substitute teacher to keep a closer eye on Norman. Go with Granny Baxter on a comical adventure as she sets out to discover what's going on with her trouble causing grandson and his friends at Mount Vernon High School. With any luck, she will learn the truth behind Norman's drinking, smoking, and swearing troubles.
