The episode starts with Mr. Krabs painting a sign that says "New Business Hours: 6 AM to 11 PM." Squidward then criticizes that this new policy is unfair, while SpongeBob then suggests some earlier times that they can go to work at. As he is hanging the sign on the window, Mr. Krabs finds out that Plankton reopened the Chum Bucket for twenty three hours a day. He announces the Krusty Krab is opening twenty four hours, to be better than the Chum Bucket much to the dismay of Squidward and the excitement of SpongeBob. This was Plankton's plan to force SpongeBob to crack and tell him the formula. However, after several days of nonstop service, SpongeBob is still going strong. As a result, Plankton calls, placing an order for 10,000 Krabby Patties under the disguise of Peter Lankton.
After 43 days of nonstop service, SpongeBob finally cracks, and cannot finish the order because everywhere he looks, he sees killer Krabby Patties. Plankton then throws a flyer at SpongeBob, saying: "Dr. Peter Lankton, Psychiatrist, specializing in Krabby Patty phobias."
SpongeBob goes to the Chum Bucket, which is disguised as Dr. Lankton's office, and meets Dr. Peter Lankton (who is really Plankton in new clothes and a fake mustache and beard). Plankton tries several methods to get the formula out of SpongeBob, all of which end with Plankton getting crushed by a piano.
Finally, Plankton tries hypnosis to get SpongeBob to tell him the formula and he succeeds in making SpongeBob fall into a deep sleep. Unfortunately for Plankton, he cannot get SpongeBob to wake up and tell him the formula, even after trying several loud and annoying sounds in an attempt to wake him up.
Meanwhile, SpongeBob dreams that he is jellyfishing when a giant Krabby Patty appears and eats him up. He then finds himself in his bed, and a giant Krabby Patty enters the bedroom. The Krabby Patty turns out to be friendly and gives SpongeBob a cookie-pizza and chocolate milk, thus curing his fear. SpongeBob wakes up and says he's cured, and goes back to the Krusty Krab as Plankton begs him to return and reveal the formula to him, insisting that hypnosis and therapy do not work, and that he is still very sick.
When SpongeBob gets back to work, he tells Mr. Krabs that he's okay, and that all he needed was a little sleep. Mr. Krabs says that there will be no more 24 hour shifts, "...because 23 hours will be plenty!" They laugh a little but Mr. Krabs tells SpongeBob to get back to work.
"OK, forget that."
Deleted Scene Storyboard: The Krabby Patties taking SpongeBob in cave
On the storyboard featured on the Fear of a Krabby Patty DVD, they show Plankton waiting for SpongeBob instead of him having to get him up immediately after sitting down. There was another one when a bunch of Krabby Patties from a cave bring SpongeBob to his bed after he gets eaten by a Krabby Patty in his dream. Yet again, SpongeBob says another "K-R-A-B-B-Y-P-A-T-T-Y says I" during the day/night montage. Also, SpongeBob talks to Krabby Patties more in the storyboard animation. Squidward having bags in his eyes was originally going to be the end theme.
Normally, in a restaurant open 24 hours, there are different employees that work different times in the day (some at day, some at night). It is actually illegal to work your employees this long.
In 2005, this episode and "Shell of a Man" were nominated for an Creative Arts Emmy for Outstanding Animated Program, but lost to the Comedy Central animated series South Park.
This is the first episode to use the 3-D computer coloring rather than digital ink and paint or traditional cel animation. This is pretty obvious, as the colors are duller, and the characters' facial expressions are also different.
Mr. Krabs previously made the Krusty Krab open 24 hours in one day in "Graveyard Shift." However, unlike in the aforementioned episode, Mr. Krabs stays at the Krusty Krab with his employees, and thus, suffers from the same lack of sleep that they do.
At the beginning, SpongeBob pinches himself nine times.
From June 2009 to April 2010 (The mistake corrected,) Charter Communications & Time Warner Cable mistakenly labeled this & "Shell of a Man" as the shopping show "SpongeBob Fun."
In "Help Wanted," "Employee of the Month," and "The Clash of Triton," SpongeBob makes possibly millions of Krabby Patties in seconds with no mental strain, but in this episode, SpongeBob goes insane from making 8,659 Krabby Patties over a period of possibly 33 days (Days 10-43). However, he may do this because he had no breaks over the time period.
In this episode, SpongeBob is able to lift an entire grand piano by himself (and smash it onto Plankton). In other episodes like "MuscleBob BuffPants," SpongeBob was barely strong enough to lift a weight of stuff animals.
Running Gag:Plankton gets smashed with a piano as a result of his therapy.
Apparently Plankton, in this episode, has a cell phone. His cell phone is seen again in the later episode "Eek, an Urchin!"
When Mr. Krabs forgot how many days its been he looks tired and wrecked, but after he see's SpongeBob made some really bad patty's he seems fresh.
In Greece, Mr. Krabs at the beginning says The Chum Bucket will open for 24 hours instead of saying The Krusty Krab will open for 24 hours. It possibly was a mistake from the Greek voice actor.
This is the second episode where the Krusty Krab was open for 24 hours. The first was Graveyard Shift.
In SpongeBob's dream, the Krabby Patty tells him that he'll always be with him (in his arteries), a reference to the 1982 Universal's big movie E.T. The Extra Terriestrial, complete with the glowing finger.
Also, the fact that the Krabby Patty said he'll be with him in his arteries may be a reference that Krabby Patties have high cholesterol.
The episode's title card is similar to the start of the Heisei Godzilla movies.
In this episode, Mr. Krabs' eye stalks are slightly shorter than normal.
In the scene where SpongeBob is dropping trays at the window, the anchor on Squidward's work hat disappears.
When the largest Krabby Patty gives SpongeBob SquarePants food in his dream, the chocolate milk is orange (As orange juice) and the cookie pizza just looks like a big cookie and has no looks to a pizza.
Near the beginning of the episode, there is a solid wall behind the cashier's boat that SpongeBob bursts through; yet that section of wall is typically shown to have a window. It's just because Squidward zipped the window.
When SpongeBob gets up from his trauma, his tie is missing and it reappears seconds later.
After SpongeBob's eyelids are ripped off, they reappear in the next shot looking fine.
Mr. Krabs penciled over his painted sign. This is impossible.
