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 guise 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.

"Fear of a Krabby Patty" was ranked #11 during the Best Day Ever event on November 9–10, 2006.
The Krusty Krab was opened 24 hours a day, for 43 days, with no breaks.
This is the first episode of 2005.
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, the episode paired with it's precedor: Shell of a Man, was nominated for an Emmy for Outstanding Animated Program, but lost to the Comedy Central program, 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.
This is the last episode with C.H. Greenblatt before he created a Cartoon Network show named Chowder.
Though unconfirmed, it is also possible that the script for this episode was written before the movie, due to C.H. Greenblatt's involvement.
However, unlike in 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.
Since June 2009, Charter Communications and Time Warner Cable labeled this episode along with Shell of a Man as "SpongeBob Fun", which is said to be a shopping show, but as of April 2010, the mistake has been corrected.
The Background of the DVD cover is from the episode Just One Bite where Squidward eats the Krabby Patties at the Patty Vault.
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) with no breaks.
In this episode, SpongeBob is able to lift an entire grand piano by himself (and smash it onto Plankton). In other episodes, 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.
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.
Fear of a Krabby Patty'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, possibly because CH Greenblatt is a storyboard artist in this episode.
In the scene where SpongeBob is dropping trays at the window, the anchor on Squidward's hat disappears.
When SpongeBob gets up from his trauma, his tie is missing and it reappears seconds later.
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 the largest Krabby Patty gives SpongeBob SquarePants food in his dream, the chocolate milk is orange and the cookie pizza just looks like a big cookie and has no looks to a pizza.
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.
