Buck Strickland forces Hank to take two weeks off from work. Hank during his time off has trouble staying busy. Visiting the school, Hank learns the school's shop class has been suspended due to the existing shop teacher taking a vacation. Hank volunteers to substitute for the class while he's off work, working for free. Peggy offers Hank advice for teaching, but soon finds Peggy's advice is useless. He uses his own instincts to teach the class, and soon his class ends up becoming the talk of the school.
Peggy meanwhile is still recovering from her fall from the airplane and is forced to teach classes she's not accustomed to. The Substitute Teacher of the Year vote is coming up, and Peggy fears she is going to lose to Hank. However, before the vote, Hank gets suspended from teaching when he allows his students to walk around the school with tools. Thus Peggy is left running alone for the award and wins it. During her speech, Hank walks out on the stage and receives a standing ovation from the students. Peggy, in all her naivete, believes the students are cheering her on, and proclaims "I accept this award for all those who have fallen out of a plane and lived to win their third straight substitute teacher of the year award." However, after Hank leaves the stage, the auditorium falls into awkward silence just before Peggy exclaims "I am king of the school!".
