Forced to take a vacation, Hank goes stir crazy until he takes over as Bobby's shop teacher--and unwittingly competes against Peggy for the "Substitute Teacher of the Year" award
During a little vacation bonding with Bobby, Hank discovers that Bobby's shop teacher eloped, turning the hallowed shop class into little more than a study hall. But when Hank volunteers to substitute teach for free, he invades Peggy's territory and the competition heats up.
Barely back on her feet, but thrilled to be back in the classroom, Peggy is initially supportive of Hank's efforts and even shares with him her sure-fire, flash card teaching method. But Hank is more at home with a band saw than a flash card, and soon abandons Peggy's style for his own down-home teaching approach. Hank's improvising and unconventional technique make him an instant hit, and Peggy begins to feel threatened. With the "Substitute Teacher of the Year" awards fast approaching, she steps up her efforts to beat her husband and win the honor for the third year in a row. She turns to Bobby for the inside scoop on what the kids really think, and Bobby reveals that Peggy is seen as an insider, while Hank "has good buzz." Coincidentally (or not), Bobby is soon busted for wearing a tool belt on campus--a clear violation of the school's zero-tolerance policy regarding weapons at school. Hank is suspended, instantly making him ineligible for "Substitute Teacher of the Year."
While Hank teaches after-school shop out of the garage, Peggy capitalizes on sympathy for him by campaigning as "Mrs. Hank Hill." To no one's surprise, Peggy wins. As she positions her shiny brass trophy next to the others, Hank's shop students present him with their own handmade "Teacher of the Year" trophy (which also doubles as a clock and CD holder!).
