Mrs. Yonkers is Bonkers is the eighteenth book in the My Weird School series.
As the new computer lab teacher tries to bring Ella Mentry Elementary School into the twenty-first century with her peculiar inventions, A.J. struggles to survive without sugary snacks when Mr. Klutz bans junk food.
- This book marks the first appearance of Mrs. Yonkers, the computer lab teacher. But she also appeared in the previous book, Miss Suki is Kooky, which means that this book and Miss Suki is Kooky might have been published in the wrong order.
