Plot
After the title card, the episode opens with Francine, Muffy, Buster, and Arthur at the sugar bowl, discussing what to get Catherine for her 16th birthday. The next scene shows Francine and her dad, Oliver in the kitchen icing Catherine's birthday cake. Oliver informs her that she is not invited to Catherine's party and that it was only for people her age. Filled with anger, Francine burst into Catherine's room to let her know that she is mad at her. Catherine then yells at Oliver, saying that she has to study. Oliver then tells Francine to leave her sister alone. After that, Francine goes to the roof to relieve anger by playing the drums. Oliver enters and tries to cheer up Francine, but has no luck. In the next scene, Francine is talking to her friends about it. Francine states that not inviting her to the party is the meanest thing she has ever done to her. She then lists other mean things she has done to her, such as telling her that a monster lived in the bathtub, calling her piasso, and tagging her in a game of freeze tag, then leaving her all alone. Her friends suggest ways to get revenge. Buster tells her to get a roll of the world's stinkiest cheese and put it in her coat pocket when going to the party, but Francine refuses because she figures Catherine would notice the smell. Binky suggest putting glue in the bowling ball before the party starts, but this plan would also fail because the glue would not stay wet long and she would not know which bowling ball Catherine would use. Binky turns upset when reality always get in the way. Muffy suggests getting hand-writing specialist (Fern) to write notes to gives to Alberto to give to Catherine and Sean (Catherine's crush). The notes would say to meet in the hallway of the bowling alley. Buster would be in the security camera room filming while Binky would be producing sound. When Catherine says, "Oh Sean, kiss me." it airs on the screens of the bowling alley with everyone watching.
