After stealing Superintendent Chalmers' car emblem off his new Honda Accord, Nelson is sentenced to janitorial work. While Lisa is serving detention for snickering at Nelson spraying Groundskeeper Willie with a hose, she becomes fascinated with and develops a crush on the bully. Meanwhile, Homer takes an autodialer that was recently used in a telemarketing scam and creates a telemarketing scam of his own.
YMMV tropes can be found [[YMMV/TheSimpsonsS8E7LisasDateWithDensity here]].
* AllGirlsWantBadBoys: Explored in this episode, with Lisa coming to the conclusion that what she had with Nelson was an infatuation, and that it would never work out, no matter how much she tries to change him.
* AllLoveIsUnrequited: Poor Milhouse
* ALessonLearnedTooWell: Homer pays his debt to society from his telemarketing scam... with another telemarketing scam.
-->''"Hello, this is Homer Simpson, a.k.a. Happy Dude. The court has ordered me to call every person in town to apologize for my telemarketing scam. I'm sorry. If you can find it in your heart to forgive me, send one dollar to Sorry Dude, 742 Evergreen Terrace, Springfield. You have the power."''
* ICanChangeMyBeloved: Discussed; played straight with Marge and Homer (Marge insists that she ''has'' changed Homer, despite the evidence that he's still an often-inconsiderate slob) and averted with Lisa and Nelson (Lisa comes to realize that she could never change Nelson).
* NoodleIncident: Who knows what Nelson left in the bird bath after the attack on Skinner at his home?
** Knowing Nelson, he probably used it as a toilet.
* PetTheDog: Nelson actually does help Lisa with the line's punishment.
* ReallySeventeenYearsOld: Kearney yelling at Superintendent Chalmers and Principal Skinner to get away from his car (in yet another example of Kearney being [[OlderThanTheyLook older than he looks]])
