In Mr. Lopez's algebra class, Tawny and Twitty are doing great, but Louis is pretty much clueless. Despite his teacher's warning about the upcoming mid-term, Louis shows no concern about learning the material. Instead he spends his time with Beans working on some strange device. We soon learn what its purpose is: it's a snow machine, and Louis takes it to Principal Wexler's house to try and fool him by faking a blizzard so he will cancel classes on the day of the algebra exam. The ruse almost works until Ren comes along and blows Louis' cover. In a meeting with Mr. and Mrs. Stevens, Wexler comes down hard on Louis, suspending him for a week.

Eileen Stevens takes the job of tutoring her son while he's out of school and she puts him through a tough course of learning. But Louis still gets nowhere with the algebra. Ren confronts Louis and asks why he went to such trouble to get out of a test. Louis admits that he just doesn't understand anything about algebra but is embarrassed to admit t

Louis has a scheme to raise money for a snowboarding trip for himself, Twitty, Tawny and Tom. While everyone else is out of the house on a weekend night, he plans to turn his home into ""Stevens Manor,"" a bed and breakfast inn, and he's already got guests' reservations! When his parents leave on an anniversary trip, he and his friends put on monogrammed shirts, redecorate the house, and greet their new arrivals, who find that the staff includes Tawny playing cocktail-lounge piano and Beans as a masseur! Despite some near-disasters (like Tom turning out to be an obnoxious waiter), the guys seem to be pulling off their plan.

Meanwhile Ren is at a sleepover at Ruby's, who is down after breaking up with her boyfriend. The two plan a ""boy-free"" evening, but when her ex calls on the phone, Ruby spends the night talking to him. Ren goes home in disgust and climbs in her bed only to find--there's someone already in it! Ren hits the roof when she finds out what Louis has done and is immediately

A tearful Ren can hardly believe it--Principal Wexler is leaving his job at the school! What's more, he's going off to pursue a career as A MODEL! Louis and Twitty are extremely pleased with themselves, since it was their doings that gave Wexler the idea he could be a successful model. Now the new man in the job will be Vice-Principal Landau, a real soft touch who's mostly interested in performing magic. For a while everything goes the way the boys want it and the school is in total chaos. That's when Ren goes to Mr. Landau and convinces him to crack down, saying there are other ways to do it besides screaming and yelling at students, which he's not good at. So Landau comes up with an idea to make the students wear ""Scarlet Letter""-type signs around their necks for every infraction of the rules, from ""I Am a Troublemaker"" for Louis to ""I Am an Eye-Roller"" for Tawny!

Louis asks Ren for help in stopping Landau's new policy, but she doesn't have much sympathy until she notices that every
