Curiosity gets the best of Billy, Marcus, and Ruby when they try to sneak a peek in Lydia's class journal. Lydia, understandably upset, accuses them of snooping, and informs them that her journal is private. Besides, who's to say that she's been writing about them? She could be writing about anyone: her parents, her uncle's cat, Earl. Earl? Convinced that Lydia is writing about him, Earl transforms the school into a 1960's spyscape, and he dispatches a rogues' gallery of spies to retrieve the document. With time ticking down, Billy, Marcus, Ruby and Lydia must outmaneuver the colorful henchmen and deliver the journal into the proper hands (in this case, Mrs. Snodgrass, patiently waiting for them to turn in their journal assignments). In the end, Billy, Marcus and Ruby forego the opportunity to ""sneak a peek"" at Lydia's journal, learning a valuable lesson about the need to respect the privacy of others
