Love Notes for Muffy

Summary
When Muffy tries to bribe the judges at the science fair, Francine and Brain plot revenge.

Plot
The episode begins with a school science fair, with everyone's projects being judged. Muffy's project, however, contains a secret oven that holds freshly baked pastries, which she uses to bribe the judges. Afterwards, a dejected Francine and Brain laments Muffy's bribery, with Brain swearing revenge against Muffy.

During class, Brain is busy drawing revenge plots against Muffy while everyone else is working. However, none of his ideas are satisfactory. Francine pleads for Brain to let it go, but he refuses... when they both overhear Muffy talking with Prunella, one of the judges. Francine decides to team up with Brain instead.

Francine later sneaks a love note onto Muffy's desk, which Muffy discovers. While reading it to Prunella, Fern, Sue Ellen, and Francine, she imagines a handsome, rich man writing the love note. Her classmates are disbelieving, but Muffy is convinced that someone likes her. Fern correctly guesses that Francine and Brain were behind the love note, and confronts her about it in the cafeteria. Fern reveals she saw Francine put the love note on Muffy's desk, and that she knew Brain wrote it.

As Francine and Fern walk outside, Muffy comes running to them. She is trying to figure out who her secret admirer is and while she has narrowed down to twenty possible suspects, she is not successful. Muffy hires Fern as her private investigator, causing Fern to glare angrily at Francine. This causes Francine to imagine herself and Brain as prisoners being put on trial and declared guilty by her classmates.

Francine tries to convince Brain to drop his revenge plans because Fern found them out, but Brain is too focused to listen. Francine starts imagining him as a incredibly petty mad scientist who fires missiles that ring her doorbell just to annoy her.

Fern meets up with Muffy to report her failure to locate the secret admirer, to Muffy's frustration. Both Fern and Francine direct their anger towards Brain, with Francine wishing the love note scheme never happened in the first place. Brain realizes his mistake, but while he is rehearsing apologies to Muffy, Muffy comes up and tells them she found the writer of the love note: it's Rattles. She even wrote a response and put it in his locker.

Fearing the worst for Muffy, Brain and Francine rush to get Muffy's response before it's too late. However, they find a torn bodybuilder poster, and are caught by Rattles himself. The threat of Rattles beating them up causes both Francine and Brain to confess to thinking up the love note plot... only to see Rattles and Muffy laughing at them. After Rattles leaves, Muffy explains that Fern warned her of the love note, so she asked Rattles for a "favor", which is making Brain and Francine confess to their crime.

Francine and Brain both apologize for deceiving Muffy. Mr. Ratburn comes in to announce the winner of the science fair. Thinking he's going to announce her as the winner, Muffy requests for Mr. Ratburn to give the 1st prize award to Brain. While Mr. Ratburn is impressed with Muffy's humbleness, he reveals that she didn't win the project - it was Francine, whose project was about the nutritional value of school lunches vs. bag lunches. Brain is dismayed at how everything turned out in the end.
