Bart is made principal for a day and trades places with Seymour Skinner––what will happen when Bart needs to play by the rules and Skinner begins to plot his own revenge? Then, Milhouse gives the 4-1-1 on what it takes to be the "king of cool" at your school. Finally, after a run-in with the school bullies, Ralph is forced to learn the value of a dollar.
