I Love Lisa

"I Love Lisa" is an episode from the fourth season of The Simpsons, in which the dim-witted and socially-awkward Ralph Wiggum plays a prominent role.

Synopsis
On Valentine's Day in Springfield, Lisa's class begins constructing paper mailboxes for all the cards they are about to receive. When Ralph gets no cards and begins to cry, Lisa hastily gives him a card out of sympathy. Ralph immediately cheers up, and develops a romantic interest in his classmate.

Ralph begins to annoy Lisa at every turn, following her home and discussing his medical maladies. Lisa tries to escape the situation, but Ralph uses his position as the police chief's son to get her tickets to Krusty's upcoming 29th Anniversary Special, as well as a leading part for himself in a President's Day Pageant in which Lisa also stars. In a dramatic upset, Ralph received the role of George Washington in a segment about that president's life, beating out an obviously more talented classmate, who complained to no avail. Conveniently, Lisa as Martha Washington will be Ralph's "wife."

With Homer having convinced Lisa that nothing can go wrong at Krusty's show, Lisa and Ralph go together. On live air, Krusty begins interviewing audience members, and Ralph takes the opportunity to declare that Lisa is the love of his life and that he intends to marry her. Lisa finally loses her temper and angrily tells Ralph they are not boyfriend and girlfriend, that she never liked him, and that the only reason she gave him a valentine was because she felt sorry for him.

Ralph is humiliated and hurt, and Lisa soon regrets her actions, particularly after Bart replays the incident on videotape, pinpointing the exact moment where Ralph's heart breaks. Ralph bemoans his situation to his father, but the only way Chief Wiggum can respond is to break out Homer's tail light after a traffic stop.

On the night of the play, students sing about the lesser-known U.S. Presidents, and Bart plays John Wilkes Booth, perhaps modelling his performance after The Terminator. Surprisingly, Ralph proves to be a very good actor, inspiring the school bullies to study American history. He even moves Groundskeeper Willie to tears. The play ends with an animatronic Mount Rushmore singing "From sea to shining sea."

Afterward, Ralph signs autographs and greets well-wishers. Lisa also approaches, and gives him a new card, reading "Let's bee [be] friends." Ralph accepts the offer. Chief Wiggum watches his son and Lisa sitting together on the swings over the music of the Monster Mash.
