The mailfish goes to the Krusty Krab with a letter for Squidward, who is not at his post. SpongeBob sees this, and inflates some balloons, shapes them into Squidward's form, and stands at the cash register, impersonating his co-worker. Squidward's nose blows up, but the mailfish gives him the letter anyway, and runs out, screaming. The balloons pop, waking up Squidward, who was asleep under the register. When he sees the letter, he becomes jubilant and SpongeBob joins the cheer. Mr. Krabs comes out and asks what Squidward's so happy about. Squidward tells him his script was accepted and that he quits. He walks to the front door, reading his letter. However, when he learns his script was not accepted, he turns around and returns to his post. SpongeBob gives him the idea to perform the play at the Krusty Krab. Mr. Krabs refuses to allow it at first, but when SpongeBob says he can charge customers double for the show, Mr. Krabs goes for it, but with one warning: if so much as one Krabby Patty is late, he'll shut Squidward down. SpongeBob suggests the event be called "Singy Eaty Time," even though Squidward says that there is no singing. Despite this, Mr. Krabs loves it.
The Krusty Krab holds auditions for parts, and a long line of anchovies await their role. When they learn they won't be paid, they make a hasty retreat. All that's left is SpongeBob, whom Squidward dejectedly says has all the other parts. That night, people head to the Krusty Krab for Squidward's play. When the curtains rise, the cashier's post is replaced with a cardboard version and Squidward recites his lines. A fish comes along and asks for a Krabby Patty. Squidward shoos him away, but Mr. Krabs pops out from the window and reminds Squidward of his warning. Squidward delivers the order to the table, reciting lines which criticize the customers and the food. Squidward returns to the stage, when a customer wants a refill. Squidward shouts at him, but Mr. Krabs orders him to fulfill the customer's request. Squidward walks over with a bucket of soda and splashes it on the customer. When Squidward returns to the stage, a customer wants ketchup on his patty, and Squidward squirts him with the condiment. Mr. Krabs again reminds Squidward of his warning, to which Squidward calls Mr. Krabs his "skinflint boss." Mr. Krabs is about to get angry, but Squidward tells him it's part of the play.
Squidward refers to "the worst part of my job," SpongeBob. The stage rotates, so the audience can see the side of the kitchen with SpongeBob, who thinks he's forgotten the lines. Squidward tells him to act like himself, so he acts like a garbage truck, flinging a bag of garbage at Squidward. Two fish try to get their orders, but Squidward ignores them, reciting his lines. The customers finally lose their patience, and angrily demand Krabby Patties. Mr.Krabs tells Squidward that they haven't gotten their orders, and Squidward asks SpongeBob (still acting like a garbage truck) where the patty is. SpongeBob goes back to normal, but sees the patties are burnt. He apologizes for ruining the food, but Squidward serves the burnt patties to the customers, despite SpongeBob's warnings that they're not fit for consumption. The customers are not happy with the quality of their meals, and Squidward tells them they wouldn't know quality "if it hit them in the head," to which a customer hurls his patty at him. The rest of the customers are eager to join in, but SpongeBob encourages them to respect the Krabby Patty. He has won them over, but when Patrick says he likes to throw food, a food fight breaks out. Mr.Krabs sells customers things to throw at his employees. When the food fight is over, Squidward and SpongeBob are badly injured, and Mr. Krabs tells them he has added new shows. Because of this, Squidward and SpongeBob laugh maniacally, and then the episode ends with Squidward getting hit by a patty while SpongeBob is still laughing.
The plot of this episode is very similar to that of "Culture Shock." Both episodes involve:
Squidward hosting an event at the Krusty Krab
Squidward's act being hated
The patrons throwing food at him
And Mr. Krabs expecting another show due to the success.
When Squidward goes to a table to give Frank Fishbowl a Krabby Patty, a piece of cheese appears below the top bun while Squidward is walking.
Patrick Star is actually responsible for Mr. Krabs getting money since he started back up the food fight SpongeBob had stopped.
The play's title, Squidward: Strokes of Genius, parodies the title of the 2004 film, Bobby Jones: Stroke of Genius, which was based on the life and golfing career of Bobby Jones.
SpongeBob puts only five Krabby Patties on the grill, but when they are burned, there are ten.
When Mr. Krabs scolds Squidward for not serving the customers, he's behind the wall, in the kitchen. When the stage turns around, Mr. Krabs is gone. When Squidward says he's "underpaid," Mr. Krabs is in the audience. When the people chant "We want Krabby Patties!," Mr. Krabs is on the stage.
SpongeBob's shade of yellow went from normal to deeper green when he celebrated getting the parts.
