Summary
When Francine and Brain are locked in a stiff competition to win student of the month, Muffy talks Francine into "borrowing" Buster's toy and letting Brain take the blame for it. As the lies grow and the prize gets closer, Francine's guilt increases.

Plot
At the start of the episode, we see Francine and Muffy at a fair. They walk into a fortune telling booth and get their fortunes told by Prunella. Prunella predicts that she will have "lunch with a stranger" and then Arthur and Buster ask if they can eat lunch with the pair.

It skips to the next day and Mr. Ratburn shows the class who is the point leader for the student of the month, Francine. Mr. Ratburn then reminds the students whoever wins will get a special prize lunch with local weatherman Thunder McDuff.

Brain gets more points added on and is now in the leader, Francine and Muffy are furious! They walk into The Ice Cream Shop and they spot Buster showing The Brain his new toy. A crude idea for vengeance comes to Muffy, to steal the toy, put it in The Brain's backpack, and frame him for it. This will cause him to lose points. Francine's conscience comes in to play, but Muffy persuades her to think evil.

Back at school Buster is playing with it and showing it off to his classmates. Francine's conscience comes in again, but once again, she gets tricked out of it by Muffy. Muffy then reminds her classmates to get to class. Francine comes in to take the toy, but gets goo on her from the toy. Her shirt and hands get stained and tries to hide it.

Class starts and Francine opens Brain's backpack and puts the toy in. Muffy turns it on and Buster notices, the Brain opens the backpack and he gets in trouble by Buster and Mr. Ratburn. The Brain unfairly loses 10 points from the Student of the Month and then loses 25 more points. Since it is the last day of the month, Francine wins, but is not so proud of herself, but Muffy is.

They go to Francine's apartment, but Francine is still feeling bad thinking she will get caught. They go to Prunella's house so she can predict the future. Prunella makes up a fake prediction and Francine then thinks everything is going to be fine.

Arthur and Buster asks Francine to help them find out who put Buster's toy in Brain's backpack and Francine starts to feel bad again and seems suspicious. But Muffy has a plan, to make Arthur and Buster seem untrustable so the next day they tape cheat sheets to both of their desks.

Arthur and Buster are still trying to figure out who did it.....

Mr. Ratburn finds the cheat sheet by Buster and he gets in trouble. Francine cannot deal with the guilt and they turn themselves in to the principal.

Brain is given the lunch with Thunder McDuff. Francine and Muffy are forced to do community service, and The Brain invites Muffy to the lunch while Francine helps the 2nd graders with softball practice.
