Query: A Funny, Funny Book

Yikes! Grandma's a Teenager is a really funny book. It is about Zack's grandma who keeps on getting younger and younger. There are two parts that I think are the funniest. One of them is when Zack's grandma becomes a little kid. She gets in a fight with someone and has to go to the principal's office. The other one is when she is about two or three years old, and she says it is her birthday. Zack's dad asks her what she wants for her birthday and Grandma Leah says in a baby voice that she wants a pony. Zack says that they can't fit a pony in the house. Grandma Leah says a small pony is fine. I would recommend this book to anyone who likes to laugh a lot.
