Charlie is frustrated because he cannot find his books for an upcoming microbiology test. His brother John admits to accidentally eating Charlie's books, mistakenly thinking they were toilet paper. However, John then starts displaying a vast knowledge of microbiology after "absorbing" the content from the books. Charlie decides to exploit this by having John take the test for him in disguise. At school, John aces the microbiology test by answering all of the professor's questions correctly, to the surprise of Charlie and the professor. Charlie is thrilled that his plan worked, while John is excited to continue attending school as Charlie.
