Had come of age and unemployed, Peter decides to go back to school to take the elementary school. However, his academic performance continues to be poor so much so that his grandmother to play for the votes of a report card to the football pools coupon. The grandmother with the votes of Peter will win, using the amount paid to renew their tavern, without giving any money to his nephew, who will retaliate by closing all his family in the bathrooms of the new restaurant. Eventually Peter was rejected despite the efforts of his teachers, but Peter does not seem to be over: receives, in fact, a visit to Camazzo, her neighbor and Head of the third class of the Navy, which gives him an envelope containing the fateful "call to Arms".
