Mom got Calvin a book from the library. Calvin complains to Hobbes that it's summer. With only three months to goof off, he's not wasting precious days reading books. He says summers are for vegetating. He says everyone knows it's not entertainment unless you can sit in the dark and eat.

Calvin asks Hobbes if he's reading the library book Mom had gotten for Calvin. Hobbes is engrossed in reading it. Calvin asks if it's good, if it's exciting, if he's having fun. Hobbes quietly sits reading. Calvin yells at him asking how it could be fun when it's so quiet.

Calvin says he's going to do something fun while Hobbes reads the library book. Calvin crosses his arms and says he'll be having the time of his life, while Hobbes will wish he was. Suddenly, Hobbes is startled by something in the book. Calvin wants to read over Hobbes' shoulder. Hobbes holds the book closer and tells Calvin to do something fun.

Calvin hands Mom the library book she had gotten. He says he read it. Mom asks what Calvin thought of it. Calvin tells her it made him see things differently. He has a lot to think about. Mom says she's glad he enjoyed it. Calvin tells her it's complicating his life and not to get him any more.
