This is a continuation of the 2nd book, "Rodrick Rules". It's the second half of Greg's seventh grade school year. On Valentine's Day, the Heffleys go to church. Inside the car, Greg realizes that he is sitting on chocolate. He complains that everyone would laugh at him if they think he pooped his pants. After one huge argument, Greg ends up wearing his mother's pink sweater like a kilt. At church, Greg calls Manny a name. Manny starts bawling, causing the whole family to leave. After that, the mother bans the use of any bad words, and whoever broke that rule would give Manny some money.
