Freddie joins Spencer to go fencing and have some "guy time." When Spencer's rival, Doug Toder, sees how good Freddie is, Spencer puts Freddie up against him in a match of fencing. Carly is mad at Spencer both for not helping her out during the visit of their nerdy cousins, the Dorfmans, and his obsession with fencing, so she stops him from doing it by telling Freddie's mom. Meanwhile, Sam and Freddie engage in a bet that if Sam can finish a book in a week, Freddie will stick a washing hose down his pants with the water turned on to make it look like he urinated in his pants. Sam gets interested in books for the first time and wins the bet.
