One morning, Squidward is trying to sleep, when he gets waken up by SpongeBob, who is running around. Squidward says that he is "screaming like a banshee." Spongebob is convinced by Squidward that he is not normal. After Squidward goes to his home, while he is sleeping, Spongebob sits on his body, this freaks Squidward. Spongebob asks Squidward how does a person become normal but he kicks him out in such furor. He proceeds to look at a video on "How to be Normal" in order to change his ways. At work, SpongeBob slowly changes over a three-week time period, becoming a more rounded-shaped sponge without holes, lacking his buck teeth, having a small nose and big freckle-less cheeks. He also becomes more mild mannered than his usual self.
Along with his new appearance and personality, SpongeBob purchases a new suburban home and works in a cubicle at the Krusty Krab like "normal" people do. Instead of making Krabby Patties the regular way, he prints them out. Mr. Krabs likes this at first, until he realizes that they are printed on paper. He soon loses his job after the customers notice the new tasteless Krabby Patties.
Afterwards, SpongeBob goes over to Squidward's house and talks to him. He states that Squidward is not normal, pointing out that Squidward has various abnormalities, such as a large "bulbous" nose, odd eyes, and wearing no pants. Angered, Squidward kicks SpongeBob out of his home.
Upset, SpongeBob enlists Patrick's aid to make him abnormal again. After a trial of odd tasks, SpongeBob slowly regains his buck teeth, holes, freckles, and other former traits. First, they slide through the town on some water in their underwear, and then are sent flying into an exhibit in the zoo. However, in Patrick's home, he soon transforms back to "normal," concluding that he has become "permanently normal." SpongeBob and Patrick begin crying, but a few moments later, Squidward appears at the door in his "normal" form (wearing pants and has a large round head, "normal" eyes, and a small nose). This snaps SpongeBob out of his normal state and returns him back to his old self. He hugs Squidward and thanks him for making him his true self again and compliments Squidward that it is "a wonderful weather they're having."

SpongeBob mentions the episode title when he says "I'm Not Normal?"
The part where SpongeBob says "Hi, how are ya?" has become a popular internet meme.
As SpongeBob and Patrick are belly-sliding through town, they go up a ramped truck. Oyster Stadium can be seen as they are falling.
When SpongeBob says Tap, erus uoy era?, it's backwards for Are you sure, Pat?
When SpongeBob is having tea with Squidward, Squidward's 483 self-portraits from the sister episode "Gone," can be seen.
In the episode "Squid's Visit," Patrick said that Squidward only went to his house to take back some stuff that he borrowed, but in this episode, Squidward went to Patrick's house near the end to find SpongeBob. It is most likely that this episode took place after "Squid's Visit."
There was nothing in the kitchen when Squidward first looked inside. Then seconds later, there is an office stall when he walks in.
When Squidward and SpongeBob are talking, the "L" on SpongeBob's name tag reading "Hello, I'm Normal" constantly changes in appearance.
During SpongeBob's first "normal" day, his freckles constantly appear and disappear.
When Squidward is riding his bike to his house, he looks up and sees SpongeBob's "normal" house. When the camera pans out for us to see all 3 houses, SpongeBob is not there. But when the scene cuts to Squidward, he is there.
The Krabby Patties made from SpongeBob's computer were shown to be real and edible. It was paper only when one of the costumers took a bite into it.
When SpongeBob and Squidward are having tea, Squidward is holding a teacup. But when SpongeBob begins criticizing Squidward, the teacup disappears for the remainder of the scene.
If one plays the scene where SpongeBob fixes Squidward's face frame by frame, the viewer can see Squidward's face was already the original shape before he fixed it back.
When SpongeBob talks backwards, he says "Tap erus uoy era?" (backwards for "Are you sure Pat?"), but closed-captions say "Chap beru soy era."
When "normal" Squidward is first shown, he only has 2 legs. But when SpongeBob is hugging him, he has all 4 legs.
