Graduation is the twenty second episode of the seventh season and one hundred and fifty first episode overall, as well as the last ever episode of Malcolm in the Middle. In the series finale, Malcolm has been accepted into Harvard and is getting prepared for his graduation of North High School.
Malcolm struggles with his valedictorian speech, Hal finds out that the family may not have enough money to send Malcolm to college.
Meanwhile Reese is moving in with Craig, and since they're both leaving they decide (along with Dewey) that Jamie should have the childhood they never got, one free of threats.
As such, they destroy their "nuclear option," evidence of the worst thing they ever did: fake an X-ray of Lois having cancer to sneak away with bad report cards, and a way to destroy each other if someone had nothing to lose.
When Malcolm reasons that he could've taken the job, become rich and bought his way into office, Lois explains that he needs to struggle in order to understand, represent, and empathize with families like his own so that he can be one of the best presidents in American history.
Hal also states that Dewey is expected to be rich and successful. In the audience, Hal sees that Francis has a name tag for a job, and Hal asks why he wont tell Lois.
Malcolm then becomes furious with how high his parents' expectations are for him, and Lois tells him to look her in the eyes and tell her that he can't do it. Francis reveals that he has had the job for 2 months and loves it, but he enjoys making her angry and arguing with her by letting her believe that he is unemployed.
Three months later, Francis argues with Lois over the phone about how "he'll get a job when he's good and ready." He then hangs up on her, Piama hands him his lunch, and he heads of to work.
Malcolm and Stevie Kenarban are offered a dream job in lieu of college, however Lois immediately turns down the offer for him.
Furious, Malcolm demands to know why and Lois explains that she and the family expect him to go to college, work harder than all of his peers(who will still look down on him), graduate, start off as a district attorney or running a foundation, be elected governor of a mid-sized state, and eventually become president.
Dewey then begins to feel lonely, as he believes that the "nuclear option" represented the bond he had with Malcolm and Reese.
Reese tries to be a permanent janitor, enlisting Ida's help to create a mess so big, by the time he finishes cleaning it up, he will have worked long enough to be considered a full-time worker .
