Dewey's Special Class is the 18th episode of Season 5 and the 103rd episode overall.


Dewey is asked to take an IQ test by his counselor. Fearing that the IQ test is the same test that got him placed with the Krelboyne class, Malcolm plans to sabotage Dewey's test. Trying to convince Dewey to throw the test and failing, he enlists Reese's help. However, his poor test taking skills lands Dewey in the emotionally disturbed Buseys class, rather than keep him in the normal education. Feeling guilty for it, Malcolm tries to convince the counselor to retest Dewey. Despite being sympathetic to his plight, she tells Malcolm she can't do anything about it and he'll have to wait until then. This makes him worried because if Lois finds out about him sabotaging Dewey, he'll suffer a lengthy grounding. Meanwhile, Hal is recruited by Craig to be his partner playing Jump Jump Dance (a parody of Dance Dance Revolution) at a restaurant arcade. Reese tries to figure out what kind of genius he is. In the end after taking over the class from the teacher, Dewey tells Lois about Malcolm's actions, which get him grounded for sabotaging Dewey's education.


In the cold opening at the Grotto, Otto and Francis are holding a press conference to blow up a dam that is blocking breeding grounds for endangered silverback trout followed by a catered lunch. Francis observes through his binoculars the dynamite looks like a picnic cooler. Otto detonates the dynamite blowing up his truck realizing too late that the dynamite and the cooler were accidentally switched.

The Wilkersons are at an arcade Malcolm states that Dewey got to pick the restaurant for dinner and is unsure whether it is a treat for Dewey or a punishment for everyone else, assuming it must be a little bit of both.

Malcolm coaches Dewey on how to "throw" an IQ test so he will not end up in the Krelboyne class. He mentions his concerns because of his own experiences. Malcolm also mentions to Dewey that being in the Krelboynes will make him a target to potential bullies. When he refuses and announces his intent to join the Krelboyne class, Malcolm is desperate to put a stop to it. Despite Stevie's warning against his plans, Malcolm points out that being in the class made him a potential target to bullies. He has a right to be concerned because the same fate could befall on Dewey if he allows him to join the Krelboynes and ultimately allowing Lois to control his future like she's doing to Malcolm. He memorizes the test enough to give the answers(half of it right and other half wrong) on a paper. Stevie states they'd need an idiot to take the test, just then Reese runs in informing the two he went to the library to figure out what kind of genius he was and discovered that people can download internet porn on the computers and the librarians can't do anything to stop them. Malcolm manipulates Reese to take the test for Dewey, hoping to keep him in the normal class knowing Reese would never be smart enough to get into the Krelboyne class. However, his poor test taking skills lands Dewey in the emotionally disturbed "Busey" class, instead of keeping him in the regular class like Malcolm wanted.

The teacher Mr. Phil Sheridan informs Dewey of the rules and how he can't yell or touch anyone but he is allowed to cry quietly. Dewey sits down next to a boy named Chad who wears mittens and has signs on him. Chad aska Dewey if he can scratch his nose but Dewey sees the sign on him says "Do not touch, bites" Chad claims he can ignore the sign. However there is a sign on his back that reads "Do not ignore the sign."

Dewey tells Malcolm about being put in the Buseys remedial class. He feels guilty for ruining Dewey's chances to remain in the normal class. Knowing that Lois will be pissed off with Malcolm later on, he offers Dewey his paycheck of $198 to help him cover up the truth until he can talk to Mrs. Welsh and convince her about getting him retested again. To keep Lois from finding out the truth, Malcolm covers for Dewey by lying to her that Dewey got into the Krelboynes. This is only to cover up while he tries to help get him out of the class.

At Dewey's school, he speaks to the school counselor, Mrs. Welsh, and tries to convince her to retest his younger brother. Malcolm tells her that Lois is a recovering addict who had a "relapse" the morning of Dewey's test. He claims this is due to her anger over finding out about Reese's latest infraction in breaking the law with an unknown and destructive prank he committed. He claims it was both the relapse and their brother's arrest that accounted for Dewey being stressed out enough to scoring the way he did. He also insists that Mrs. Welsh doesn't contact Lois about the matter. When she asks about the reasons against it, Malcolm claims that Lois is a mentally unstable drug user and the slightest tweak could set her off. He also mentions that having Mrs. Welsh talk about Dewey's poor scoring that lead to him being in the remedial class would make things worse at home and Lois will be stressed out even further to continue drug use. While sympathetic to his plight, she informs Malcolm that she can't do anything but assures Malcolm that she will only communicate with his father from now on. This makes Malcolm worried because if Lois finds out that he sabotaged Dewey's test, he'll face a lengthy grounding. Mrs. Welsh's decision unknowingly works in Malcolm's favour since Hal is too distracted by the dance competition to pay attention to the guidance counsellors messages.

The next day, the Busey class is making flowers out of tissues, Dewey questions why and Mr. Sheridan tells him since tissues are soft and non-toxic they are safe to use so no one gets hurt or sues the school, he also informs him he only gets paid 4 days a week. Dewey is off put by the methods used including doing math without pencils, history without hardcover books and wonders if they could at least have real art supplies. Mr. Sheridan informs him that it would mean the kids may try to stab with scissors and eat paste, and some attempted to eat scissors and Chad tried to stab with paste. Dewey informs him teachers are supposed to help their students and if he made an effort to help them maybe he wouldn't be so unhappy. Mr. Sheridan claims he'll never get through the year with an attitude like his and he should take his hopes and dreams and let them die so he can grow up not regretting how much ass he kissed in grad school. Hanson thanks Dewey for trying and Chad claims if he can get his hands on the paste, he'll stab Mr. Sheridan for him.

Meanwhile, Reese tries to figure out what type of genius he is. After failing at several attempts (including "Hypnotist", "Archbishop", "Dictator for Life", "Escape artist", "Skyscraper Repairman", "twin", "fireproof" and "talks to animals") Reese moves on to the next items on his list of potential genius vocations. Lois reminds him not to bother figuring out what genius vocation he is because he's neither book and street smart.

After Dewey teaches Hanson why the sound of an approaching motorcycle sounds different than the sound of a retreating motorcycle (the Doppler effect) Hanson excitedly celebrates that he learned something but his victory is short-lived before Mr. Sheridan says he should sit down, visually disappointing him. Dewey then realizes that his classmates aren't disturbed as much as they are starved for stimulation. Mr. Sheridan hasn't done anything to teach the class because he's too wrapped up in his own miserable life. Dewey decides that enough is enough and announces that everyone who hates the way they are being treated to follow him. Dewey leads the class out of the classroom and to a takeover of the Krelboyne class whereupon the Buseys seize musical instruments, art supplies, stationary items, books and other supplies and return to their classroom to actually start learning. Realizing that he had lost control, Mr. Sheridan cowers in the corner and repeatedly says "a quiet mind is a happy mind" eventually he concedes defeat and quits his job as a teacher. Because of his actions in taking over the class from the incompetent teacher, Dewey becomes the Buseys leader.

Hal and Craig enter a Dance Dance Revolution-style contest. When Craig suffers an injury, Hal tries to turn to Lois, but ends up getting the help of a kid named Davey who knows his and Craig's routine. He only agrees to help him if he get the prize (two free pizzas) and Hal agrees. They throw down some very well choreographed dance moves and end up winning.

The next day, Malcolm informs Dewey he figured out how to cover their tracks, he created a second fictional Dewey in another school system and all they have to do is pretend he is dead for two days and they are back in business. Dewey claims it to be good news and immediately confesses to Lois about Malcolm's plot that got him sent to the Busey class and he has been there for the past two weeks. Lois is visibly furious at Malcolm. Dewey then states that they must have a lot to talk about and leaves Malcolm alone to face Lois' fury as vengeance for sabotaging him.

Reese then rushes into the kitchen excitedly to tell Dewey that he's finally figured out what kind of genius he is. Reese proceeds to punch Dewey on the top of the head, knocking him to the floor. "There it was, just staring me in the face... C'mon Dewey, please stay awake. I've got so much to show you!" Reese tells Dewey, implying that his genius superpower is bullying.
