Squidward expresses his disgust for Krabby Patties despite never having one, SpongeBob insists that he tries one, claiming that they are so popular that "the only people who don’t like a Krabby Patty have never tasted one". Squidwerd eventually does and bites only a piece of the patty off. Squidward's opinion of Krabby Patties seem to remain unchanged as he angrily says to SpongeBob that the one he tried was the most "horrible, putrid, poorly prepared, vile, unappetizing, disgusting excuse for a sandwich it has ever been my displeasure to have slither down my throat!" and literally buries the patty.
When a dejected SpongeBob leaves, Squidward desperately digs up the patty and eats the remains when he in fact likes them. He wants to have more but after already stating that he hates Krabby Patties to SpongeBob, Squidward then forces himself to sneak for one without him knowing, as he knows that SpongeBob thinks he hates them, and won't give him anymore. Squidward tries to have another Krabby Patty by stating an "order" to SpongeBob for a Triple Krabby Patty Supreme on a kelp bun, with extra sea pickles and burnt to the crisp. SpongeBob makes it, and also apologize to Squidward (who wasn't paying attention to the Krabby Patty instead) for trying to force him to like a Krabby Patty saying how he realize he wanted to make himself happy and learns not everybody as to like the same thing. After making it, SpongeBob wants to give it to the customer sense he never gets to make that kind of patty much. When realizing he/she left, he eats it (unaware that it was for Squidward himself).
Squidward then notices a half-eaten Krabby Patty on a trash can. Taking this as an opportunity, he munches the garbage and not the patty itself. He spits out the garbage and before he can eat it, SpongeBob sadly burns it, once again ruining his chance to have another Krabby Patty. After having a dream of a giant Krabby Patty as his own wife, a determined Squidward continues to try to eat another patty by coming back to the Krusty Krab in the middle of the night. He then enters the "Patty Vault," where legions of ready-made Krabby Patties are. Before he can finally have another, SpongeBob enters and says to Squidward that he always comes to work at 3 a.m. when he counts the Sesame seeds.
SpongeBob is confused why Squidward is in the Krusty Krab in early hours, why is the Patty Vault open, why is he holding a Krabby Patty behind his back and acting nervous and sweating and looking hungry before realizing that he likes Krabby Patties. Once SpongeBob asks Squidward, Squidward openly states that he indeed likes them before wolfing down the patties in the vault. SpongeBob then warns Squidward not to eat too many of them in there as they all go down to his thighs and, as Squidward sarcastically predicted, causes him to subsequently explode.
Later, a bodyless Squidward is taken to the hospital in an ambulance and a paramedic who is sitting beside him holding his tentacles jokingly says that he remembers having his first Krabby Patty.
The scene in which Squidward triggers a burglar alarm consisting of a bucket of gasoline which is spilled, lit on fire, and explodes is cut out of later airings of the episode. The reason for the censorship was never officially announced by Nickelodeon. However, the most likely explanations for the removal could be to respect the victims of September 11, 2001 or to prevent children from attempting to use and/or ignite gas. This scene would later become an internet meme. On a few airings, the first explosion is aired, but the second explosion is cut. This happens for unknown reasons but it might be because they decided to get rid of the second explosion because if there were more than one. The edited version is included on the Tales from the Deep, The Complete 3rd Season, 10 Happiest Moments, and The First 100 Episodes DVDs. However, the VideoNow versions still have this scene intact. Today, the uncut episode is still mainly aired only Canadian channels, including YTV and Nickelodeon Canada. It is very hard to find the version of the episode with this scene. The version without this scene started airing sometime in 2002. It is unknown why it was not deleted in Canada, though possibly because nothing happened in Canada on September 11, 2001 or YTV just has not gotten their hands on the edited version. The episode without the deleted scene was rated TV-Y, while the episode with the deleted scene was rated TV-Y7.
When the uncut version was aired, "The Bully" aired first and "Just One Bite" second; however, in all showings of the edited version, the order of the two episodes segments are reversed. This is maybe to make the person watching know which version it is.
The original version was only used on initial broadcasts of the episode; the altered version is used on current broadcasts and all DVD releases, as well as the Nickelodeon website along with iTunes.
The deleted scene is as follows:
Squidward: There it is, unguarded! All I have to do is... wait. It's too easy. There must be some kind of (liquid drips)... security? This is our burglar alarm? A bucket of water? Ha ha! (kicks the door open, thus spilling the bucket over) That was too easy! (sniffs the liquid) Hey, this isn't water. This is... gas! (A robot arm drops a lit match into the gas, resulting in a huge explosion. Squidward screams and enters the kitchen, but just as he thinks his pain is over, he sets off another burglar alarm. The kitchen bursts into flames for a few seconds. Then he gasps at the sight of the Patty Vault and walks over to it.)
Squidward: There it is! (cuts to interior of Krusty Krab with camera zooming in through window to the Patty Vault. Squidward approaches it as he did in the original version. The rest of the episode goes normally.)
When SpongeBob jumps out of the trash can, he appears in the style of Guiseppe Arcimboldo, a 16th-century painter famous for his portraits constructed from food items.
This episode has become very popular with YouTube Poops (edited parody versions of the episode) due to several scenes such as, when Squidward says "Does this look unsure to you?," SpongeBob saying "You like Krabby Patties don't you Squidward?" and when Squidward says "I have no soul."
This is the second episode with a popular deleted scene. The first was Procrastination.
The Krusty Krab could not hold the Patty Vault, since that thing is impossible to be inserted to the Krusty Krab through its tiny doors (compared to the vault).
This is the first episode to show the inside of the Krusty Krab that does not feature Mr. Krabs. In fact, he's never even mentioned or seen.
All the Krabby Patties in Squidward's thighs look normal-shaped. This implies that Squidward just swallowed them all without chewing them, and the Krabby Patties weren't digested and turned into another shape.
Before the Patty Vault was removed, according to the deleted scene, the Krusty Krab couldn't survive the two explosions, but it would take days or weeks to repair all the damage done. The tables would have been burned completely, and everything else would burn up, unless SpongeBob counters the explosion by throwing water on the match before it falls on the gas. But still, it would take a long time to clean up the mess of the first 2 explosions.
It is unknown how Squidward's body got back to normal after his thighs exploded at the end. It's possible that he recovered in time for the next episode "Squid on Strike," which aired one week after this episode.
In Turkish airings, Squidward is seen lying on a strainer instead of disemobied.
The scene where Squidward says "I have no soul," has become an Internet meme, as it has SpongeBob saying "You like Krabby Patties, don't you, Squidward?".
Squidward is incredibly misfortunate in this episode (ex. face burned by the grill, had his thighs explode due to Krabby Patty overload, exploded in gasoline fire twice, etc.).
There is no dialogue between the part where SpongeBob says "but it means so much that you came" and the part where Squidward says "Honey." There was a little bit of crying from Squidward, gasping, kissing, and sighing happily.
Squidward's gross-out close up ("Does this look unsure to you?") became an internet meme.
The Triple Krabby Supreme On a Stick is a reference to the Minnesota state fair food. 
The eighth scene of Squidward eating Krabby Patties was similar to the game Pac-Man.
Squidward's anger about the Krabby Patty is very similar to Ned Flander's anger from the Simpsons episode, "Hurricane Neddy."
The first act of the episode, where SpongeBob attempts to make Squidward try a Krabby Patty in different locations, is similar to the popular children's book, Green Eggs and Ham.
In this episode, SpongeBob said, "I always come to work at 3 AM," just like he was in "Graveyard Shift," yet in other episodes, he usually arrives later than 3 AM.
When Squidward says "and no one," the lines on his head are gone.
When SpongeBob tries to get Squidward to take one bite, the Krabby Patty in his hand changes throughout the camera cuts. The lettuce and cheese keep changing places in every place that SpongeBob tries to get Squidward to take a bite. This must've meant that SpongeBob always keeps lots of Krabby Patties in his pocket.
When Squidward slapped the Krabby Patty out of SpongeBob's hand, SpongeBob should've thrown it away or cremated it because it was on the floor. This must've meant that SpongeBob always cleans the floor before the Krusty Krab opens. Or he probably brought a new Krabby Patty.
In SpongeBob Comics No. 4, there's a comic called "Burn It." In the comic, SpongeBob states that he never burned a Krabby Patty in his life. However, in this episode, he did burn a Krabby Patty.
In this episode, Squidward says he never had a Krabby Patty and hates them, but he was previously shown eating Krabby Patties in "Your Shoe's Untied;" though, they may have bypassed his tastebuds and went straight into his gullet.
When SpongeBob handcuffs himself to Squidward, the handcuffs disappear when Squidward takes the Krabby Patty.
At the very beginning when Squidward says "I hate Krabby Patties," the cash register is missing.
In the uncut version, you can't see the Patty Vault through the ordering window. In the edited version, you can.
When SpongeBob says, "I knew it all along, Squidward," his front hole is colored blue for a split second.
