"Jeffy's Online School!" is the 501st episode of SML Movies.
The episode starts with Jeffy wanting to play Hungry Hungry Hippos (which Jeffy calls Hungry Hungry Mooses) with Mario and Rosalina, but they can't because Jeffy has to go to school. Jackie Chu then arrives saying that he is sick and school is cancelled so Jeffy has to be homeschooled via online teaching.
Mario brings Jeffy a laptop so they can start their online classes (Even though Jeffy refuses). They get greeted by Jeffy's online teacher, Margaret, who tells Jeffy to leave so she and Mario can have a parent-teacher conference. But as soon as Jeffy leaves, Margaret takes her shirt off, revealing her orange bathing suit, then start flirting with Mario online. Rosalina finds out and Mario tries to deny it. However, Rosalina decided to leave Mario.
Stressed, Mario comes to Chef Pee Pee to save his marriage by arranging him and Rosalina a nice dinner at Jimmy John's. Even after the dinner, however, Rosalina still won't go back to Mario so Mario decided to prove that Margaret would want anyone, not just him.
Back at the house, Mario shows Chef Pee Pee to Margaret and Margaret started making out with Chef Pee Pee. At the door, Jackie Chu returns saying that he accidentally sent them the wrong link to Jeffy's online class. Rosalina apologizes Mario for not believing him. This video ends with Jeffy telling his family to play hungry hungry hippos.
- Despite this being called "Jeffy's Online School!", it focuses more on Mario and how Rosalina thought he was cheating on her with an old woman. It could be that Logan needed a cleaner title to avoid demonetization or he decided to put “Jeffy’s Online School!” just for views due to how popular Jeffy is.
- This is the first SML video of April 2020.
- The online call with Margaret is just a video that was edited by Logan and not a real online call. It can be seen because the computer is open to that tab, titled 'QuickTime Player', a common video player on most Apple laptops.
- The thumbnail is also a bit misleading, as it hints Jackie Chu on the laptop attending online school, but in the video, it was Margaret on the laptop who was attending online school.
- Despite this, Mario has cheated on Rosalina with Peach in "Mario's Valentines Day Problem!", his pencil girlfriend one time since "Jeffy's Teddy Bear!" (though this occurred at a time when Rosalina's presence in the series was in question due to Chilly barring Elaina from the house for the longest time) and the other time with Crystal with the money in "Rich Mario!".
- This was uploaded one year later after "Invisible Jeffy!".
- This is the first episode to not feature "Brooklyn T. Guy" since "The School Dance!".
- Rosalina's face is edited to look mad in the thumbnail.
- This was the 2nd SML Movie where Rosalina Gets Angry at Mario. The first Being Rich Mario!, Where Rosalina is Angrily Yelling at Mario for Calling Jeffy Stupid.
- This is the first SML Movie in 2020 where Chef Pee Pee doesn't appear with Bowser or Junior.
- It was thought because this video is disliked by fans due to Rosalina thinks that Mario is cheating on her, which led to Rosalina going on another hiatus until Jeffy Gets Stuck!.
- Because of this and her previous disappearances, some fans have suspected that Rosalina had been cheating on Mario for a while and that she only arrived at the first place to admit to the affair, break up with Mario and give him custody of Jeffy, but when she saw Mario and the school teacher, she used it as a reason why she is dumping him instead.
- The actual reason for Rosalina not appearing recently is likely due to the pandemic. The same reason Pablo is using his characters on face time or not appearing at all. Rosalina returned in "Jeffy Gets Stuck!" meaning Elaina must have got an essential license for working outside Baltimore.
- It's also possible this video takes place after all the videos where Mario acts greedy or cruel and Rosalina is punishing Mario for his bad behavior with the entire video being a planned scheme.
- This video marks the return of Jeffy saying "Whoops It Slipped" which had not previously been used since "Chef Pee Pee The Babysitter!".
- Jackie Chu just finds out that he has the coronavirus and goes to the hospital in this episode, but he already knew he had it in past episodes. However, it could be that Jackie Chu got it a second time and then had to get hospitalized and that in "Jeffy Goes to Disney World!", he was just wearing the mask to protect himself. It could also be that he was holding in his coughs in the aforementioned video.
- During the fantasy restaurant scene, the Jimmy Johns logo can be seen in the background.
- Lovell's legs and feet are seen when Jeffy smashes the plate.
- During the dinner scene, Elaina can be seen in the reflection on the window.
- Chef Pee Pee doesn't seem to know who Margaret is in this video. This is contradictory as he has met her before in "Bowser's Mom". However, he might have forgotten, since it has been a long time since they last interacted. Or that the series runs on an unstable continuity.
