One day, on the Ned and the Needlefish tour bus, Ned comes out of the backroom and has a 6 layered wig (with ribbons) on. His band mates tease him and one accidentally chucks the wig out the window playing monkey in the middle with the drummer. He looks out the window as it flies away, right as SpongeBob SquarePants is taking a walk. It hits him in the face and he falls on the ground. As he gets up, he notices it's a wig and goes to Patrick's house. Patrick thinks it's a "brain eating alien," and rubs it (and SpongeBob) forcefully on his rock. SpongeBob yells at him and Patrick puts him down. He then chews part of the wig off. SpongeBob asks why he did that. He replies with the answer, "I thought it was a new type of cotton candy that you wear on your head." SpongeBob says it's a good idea then Patrick asks what it is loudly. SpongeBob replies with the answer, "It's my new wig!" Patrick thinks it's a stupid idea then looks at his watch, he says it's time for his weekly condiment soak. A bathtub randomly appears with a giant jar of mustard next to it. Patrick goes in the bathtub and dumps the mustard all over his body, he then asks SpongeBob for some privacy.
SpongeBob walks to work with tons of fish laughing at him, as he thinks they're laughing "with" him, when they were actually laughing at him. He then thinks his wig is making everybody in a good mood.
SpongeBob enters the Krusty Krab and wakes Squidward up, asking Sqauidward if he notices anything different about him. Squidward says he doesn't, to which SpongeBob says he's wearing a wig. He goes into the kitchen and makes some Krabby Patties, while scratching his wig, causing a lot of wig hair to fall on the meat patty. Some customers try the new recipe and aren't satisfied. All of them leave and Mr. Krabs notices. He tells SpongeBob to wear a hairnet or he leaves for the day. Sandy walks in the Krusty Krab while SpongeBob is delivering food. She is about to ask SpongeBob about Karate practice, takes one look at him, and laughs her head off. The customers at the Krusty Krab are laughing at SpongeBob's new wig when he still thinks they're laughing with him. When he thinks they're all starting to get jealous, he walks backwards into the kitchen and tells Squidward that he'll be in the kitchen if he needed him, who tells SpongeBob to hide his shame.
Meanwhile, Ned's band are in a record dealers place. The manager says they're fired because Ned doesn't have hair. The manager then says in Ned's face, "you come back with hair, or don't come back at all." That night, it's time for SpongeBob to go home, when he's moping the floor using his wig. Squidward thinks it's as functional as SpongeBob's brain, to which he takes as a compliment, but he tells him that wasn't a compliment, and that the entire town has been laughing at him. SpongeBob doesn't understand, and thinks he looks handsome, but Mr. Krabs tells him to stop wearing it to work. The next day, Sandy walks to SpongeBob's house talking about how she couldn't talk to SpongeBob yesterday because she was laughing too hard. She knocks on the odd double sized door and sees SpongeBob with the wig on, she puts her palm on his elbow and says, "We need to talk." As they are walking through Bikini Bottom, SpongeBob is talking about how his wig brought so much attention. They go in The Reef (movie theater) and watch a movie about wigs. SpongeBob sits in the front row and a lot of sea fish yell at him because the wig blocks 75% of the screen. SpongeBob turns around and says, "Please, return your attention to the movie, I know my wig is glamorus and exciting, but there's no need to start a riot." Scooter says, "That's a great idea! (everyone took out pitchforks and torches) lets start a riot!" SpongeBob screams and he and Sandy run out of the theater with the riot chasing him. hH passes the ticket holders and one says, I told you that movie was horrible." In the next scene, SpongeBob and Sandy walking through fields, they walk up to the cliff and SpongeBob makes a speech, and lets go of the wig and it flies away, SpongeBob then falls on the ground crying that he'll never accessorise again.
Then Ned is walking through Bikini Bottom screaming stuff about how his career is ruined. The wig then stuffs in his face and Ned realizes it's his old one. He puts one foot on a trashcan and says, "YES! Victory is mine!"
SpongeBob is down, walking through Bikini Bottom and seeing all these fish with Ned's wig. He then feels betrayed. He walks up to a fish that teased him the other day and complains. He tells SpongeBob to look at a giant sign that says Ned and the Needlefish, and the whole band is wearing the wig. He then realizes that he was cool before anyone else. The fish says, "You used to be cool, but not anymore..." Patrick then walks by SpongeBob and he's relieved that Pat's not wearing a wig. He lifts his arm and SpongeBob sees mini wigs attached to his armpit. Patrick lets SpongeBob borrow one, but says to wash it before he returns it. The episode ends with SpongeBob disgusted by what Patrick said.
The scene with SpongeBob's wig blocking the movie screen is a reference to a 1974Sesame Street segment where Bert and Ernie go to the movies until a lady enters wearing a tall hat that blocks the screen.
When this episode is listed on Time Warner Cable, the episode title is mispelled as "Wigstuck."
Patrick eats a part of SpongeBob's wig. But when SpongeBob goes on, his wig is full again.
SpongeBob doesn't seem to know that the people of Bikini Bottom are laughing at him, but in some earlier episodes ("Grandma's Kisses," "I'm Your Biggest Fanatic," and others) SpongeBob is embarrassed when people laugh at him.
When SpongeBob gives Squidward the hair patty, the kitchen window narrows immensely.
