Smart Jeffy is the 260th episode of the SML Movies.
Jeffy becomes smart after a freak accident!
The video starts off with Jeffy pretending to be a poop monster with his shirt pulled up and asking Mario if he can have his butt. Rosalina knocks on the door, and Jeffy plays Hide and Seek, somehow hiding inside the couch while making a weird face. Mario and Rosalina play pretend for a while, and Mario asks Jeffy if he can play with Bowser Junior. Jeffy then leaves by falling down inside the couch. Junior is playing with Thomas, when Jeffy comes in. Junior shows Jeffy a trampoline, and while Jeffy is jumping on it, he asks Junior what would happen if he landed onto the table from the trampoline. Junior lets him do so, and as a result, his pencil goes inside his nose upon impact and impales his brain, knocking Jeffy out. Junior then thinks that Jeffy is dead, and tells Rosalina (still finding her attractive) and Mario. When they hear about it, Rosalina gets upset, and Mario immediately celebrates in the hope that Jeffy is really dead. Rosalina gets Mario to call 911, and Brooklyn T. Guy comes in. He examines Jeffy, and says that Jeffy is not dead, much to Mario's dismay and Rosalina's relief. Jeffy wakes up and greets everyone. He then asks Mario why he has a diaper on the outside, and says that this would get his butt infected. Jeffy also asks why he has a bicycle helmet on, and says that he is not on a bicycle so he takes it off. Brooklyn then asks Jeffy what pi is, and he says the correct answer. After that, Jeffy is given a Rubix cube and solves it just in moments. Brooklyn gives Jeffy an IQ test, and when he gets the results, he says that he got a 300, more than even Albert Einstein got, despite Jeffy going for a 301. Brooklyn T. Guy gets Mario to enter Jeffy into the International World's Smartest Person Contest, and at first Mario doubts it, before Brooklyn tells him about the prize money, which is one million dollars. Mario immediately reacts with jackpot eyes, and shows a lot of love and respect for Jeffy, even calling him his "son", getting disappointed when Brooklyn tells him he has to wait nine months for the contest. Nine months later, the contest starts and Mario tells Jeffy that he will go to college if he wins. Jeffy says that when he gets the prize money, he will invest in oil and 3D organ printing, and get 4.2 billion dollars in just two years. The other contestants are introduced as Cody, Stephen Hawking, and Jackie Chu. During the contest, Cody gets the first answer wrong, and Stephen Hawking gets broken and Brooklyn T. Guy has to take him to the repair store. Jackie Chu and Jeffy get correct answers, until Jackie Chu is faced with the question, "What is the main ingredient in sushi?" Jackie Chu says dog, but Goodman says that the correct answer is rice, disqualifying him from the contest, leaving Jeffy as the only contestant left. Jeffy's final question is, "What is 8 - 4?". Jeffy begins to answer, before he sneezes, blowing his pencil out of his brain and back down his nose, leaving a hole in his brain. This reverts him to his normal self, and remembers his 8 - 4 experience, complete with a flashback from Jeffy's Homework!, before unh-ing multiple times and going into a profanity rant about the answer being 8. Goodman says it is wrong and disqualifies Jeffy from the contest. Later, Jeffy is playing with his diaper on his head and his helmet on his crotch, and Mario cries in defeat and misery while Rosalina says it is "nice to have the old Jeffy back", despite Mario saying that he misses the smart Jeffy and he was gonna make him money. The video ends with Stephen Hawking attempting to do a wheelie, only to trip and fall.

Smart Jeffy received positive reviews, and is considered to be one of the best Jeffy videos ever. Many SML fans stated that Jeffy is improving in this episode. Plus, Mario should be happy that Jeffy almost died and that he got injured, and Jeffy was actually smart too, considering how retarded he should be. However, fans criticized the ending where Jeffy reverted to his old self.
GameCubeDude300 gave this video a universal acclaim. He liked that Jeffy changed into someone new for once, even going as far as freaking out on every question that Jeffy got correct. However his favorite part was the rant, since he laughed hysterically.
MAFDOMiNUS liked the fact that Logan was being creative, with Junior calling Rosalina "busty tits", Mario's reaction when the Brooklyn Guy mentioned the prize, and Jeffy being smart. He gave the video five stars and the Jurassic Park Seal of Approval.
