Nerds vs. Jocks The Jocks and the Nerds are sworn enemies. Both cliques are exact opposites. While the Jocks are strong and popular, the Nerds are weak and unpopular, which makes them easy targets for the Jocks to pick on. The Jocks will usually attack any Nerd who goes near the Gym or Football Field, and the Nerds will attack any Jock who goes near the library, although this very rarely happens. The Nerd leader Earnest continually schemes to humiliate the Jocks, and Chapter 4 deals with Jimmy getting sucked into them while trying to get the Jocks under control.
