It's Hal and Lois' 20th anniversary and Hal has no idea what to get her. He becomes so paralyzed with stress, that he begins sleepwalking and Reese takes advantage of it. A bully nominates two Buseys for student body president. Meanwhile, Malcolm takes up the guitar.
Hal informs him that their twentieth anniversary has to make up for nineteen crappy ones where he put Lois through hell by making a marching band crowd their room, knocking her unconscious with their closet door trying to surprise her with champagne and arranging for two planes to make a heart in the sky only to crash into each other. Hal claims that the last one wasn't even the low point of the day.
At the schoolyard, Dewey asks Chad if he is trying to make Coach Cleary burst into flames again. He is then approached by Hanson and Zoe who excitedly tell him that they befriended a normal boy named Kyle Rogers who signed them both up for the upcoming Student body president election. Zoe is excited since it is like a dream except without a crying armless scarecrow. Her and Hanson both agree that they won't let competition come between them. As the other Buseys congratulate them, Dewey sees through Kyle's facade and decides to even the score.
In the kitchen, Malcolm approaches his mother and tells her he found the perfect way to protect his opportunity, he bought a guitar and figures if Dewey has musical talent with the piano he must as well. Lois asks him if he really bought it, Malcolm reveals he only rented it for a few days. Lois claims it'll be enough time for him to realize he can't do it, she apologizes and tells Malcolm his brain doesn't work the same way Dewey's does. She states Dewey is a floater who will simply float and drift through life and things will work in his favour, but herself and Malcolm are burrowers who are at their best when their heads are down and are grinding through a mountain of drudgery. Malcolm doesn't believe she knows what he'd be good at before he does it and asks how he'd be at a few activities. She tells him he'd be bad at scuba diving, good at mountain climbing and a disaster at flamenco dancing. Malcolm states it's a good thing she wasn't John Lennon's mother, Lois claims if she were John Lennon's mother, he'd still be alive.
In the middle of the night Hal grabs Reese and drags him into the kitchen, Reese assuming he is in trouble attempts to argue against any accusations and the only reason he missed so many days of school is because his watch stopped and he thought it was Saturday all week. Hal tells him how he needs to find the perfect gift for his and Lois' upcoming anniversary and is so stressed out he cannot think straight. Reese is unsure if his father is stable or not so he tests it out by telling him his shoe is untied and he ties it except he isn't wearing shoes, Reese realizes that he is sleepwalking and decides to take advantage of it by getting Hal to get him $20 from a secret hiding place (one of the bronze fish ornaments hanging in the kitchen) before asking him to get him a sandwich with chips and a soda and purr like a cat while he eats, when Hal goes to do it with no hesitation Reese sees the amount of power he now holds.
Malcolm is practicing his guitar in the garage when Reese wanders in, he tells Malcolm he'd be willing to forget what he saw if he tells him all that he knows about sleepwalking. Malcolm states that people who sleepwalk usually suffer from an overwhelming amount of stress, Reese leaves satisfied.

- Francis was born on the day Hal and Lois got married (Flashback). Since this was their 20th anniversary, That means that this episode must have taken place on his birthday and Francis is 20 years old, turning 21 in this episode. Additionally, Francis' birthday is never mentioned in this episode. This is the second episode to take place on their anniversary and make no mention of Francis' birthday. (Dewey's Dog)

- In Dewey’s Special Class, they say that the Buseys don’t have recess with the rest of the school because they make them too sad, but in this episode, they are having recess with the rest of the school. It is entirely possible that the decision was overturned after Mr. Sheridan quit.
