First Aired 2/27/92
When the results of Bart's vocational survey suggest he'd make a great cop and Lisa learns her dreams of becoming a professional sax player are doomed by genetics (she has stubby fingers, which would make saxophone playing impossible, even though she doesn't exhibit any problems), their roles at Springfield Elementary are reversed: Bart becomes a hall monitor who cracks down on school misbehavior (after surviving a run-in with Snake during a police ride-along) while Lisa becomes a rebel who smokes with the bad kids, gets detention, and pulls off a teachers' edition textbook heist that could get her expelled.
This episode contains examples of:
- Big Brother Instinct: When Bart finds out what Lisa did, he takes the blame, staying in school due to his work as hall monitor. When she asked why, Bart tells Lisa that test or no test, she's the one with the makings to be a success.
- Break the Cutie: Learning that the only thing she is worthy of is being a housewife and being rejected from becoming a professional saxophone player due to her stubby fingers broke Lisa down to the point of becoming a rebellious student.Lisa: Dear log: This will be my last entry, for you were a journal of my hopes and dreams. And now, I have none.
- She was broken further when she realize she went too far stealing the textbooks.
- Brutal Honesty: "Yeah, well, I'll be frank with you Lisa, and when I say 'frank,' I mean, you know, devastating."

- Epic Fail:
- Snake attempts to run over Bart, only for his car to get caught in the narrow pathway and catapult him out the windshield, injuring him horribly.
- Marge tries to console Lisa by telling her a story from her childhood about how she wanted to be an astronaut, but her sisters told her women can't be astronauts because they'd "distract the men." Little Marge insisted she would too become an astronaut and in the future people would live on the moon. Marge finishes her story by saying her sisters were wrong because there are women astronauts...and that she was wrong about the living on the moon part. Lisa is not amused, especially since Marge misses the point of her own story which would've been more uplifting if she had become an astronaut herself.
- The teachers have trouble teaching without the teachers' edition textbooks. In fact, they have so much trouble that they are considered to be massive idiots.
- Thanks to their dog teams tracking the scent of books, the Springfield Police conclude that the Springfield Library is where the stolen teachers' editions are being kept and use an armoured car to ram the door down.
- When Bart tells Homer and Marge about his results, Marge mentions how he considered joining the police, only for them to decline him for being too heavy. He then corrects her by saying, "No, the Army said I was too heavy; the police said I was too dumb."
- Even Evil Has Standards: When Lisa points out that Bart used to appreciate the value of a prank, Bart responds, "Yeah, but even I had my limits."
"I know. I know!"
- Even Lisa was aware that she went too far, but went through with it anyway, feeling she has nothing to lose anymore and cries.

- Informed Flaw: Lisa's stubby fingers will supposedly prevent her from being a professional saxophone player, but she's never expressed any difficulty with her fingering before or since.
- Innocently Insensitive: Lisa bemoans loudly that becoming a housewife is a Fate Worse than Death, right in front of a hurt Marge.
- Jerkass Has a Point: As much of a smartass she was being, Lisa is right that Ms. Hoover is a completely incompetent teacher who relies entirely on her teachers' edition textbook to instruct the students. Once it's stolen, Hoover pulls a Screw This, I'm Outta Here! rather than trying to teach without it.
- Know When to Fold 'Em: After getting 600 days of detention handed to him for constantly snarking back to Skinner, Bart concedes "Maybe I'll just shut my big mouth".

[stares from the students] Ahem.
