On his lunch break, Squidward encounters Squilliam Fancyson with a group of his fans. Squilliam asks Squidward what he has "accomplished" since high school, Squidward, panicking, tells him that he owns a five-star restaurant. Squilliam tells Squidward that he and his friends will come to his restaurant that night, and Squidward is very shocked. He begs Mr. Krabs to let him have control of the Krusty Krab for the day, and when he explains that Squilliam's coming, Mr. Krabs accepts because he knows that Squilliam has money (though, this is only faintly implied).
Squidward attempts to train his employees to turn the Krusty Krab into a fancy restaurant, including Patrick, who thought that he was joining the corps and is given the job of collecting the hats. SpongeBob, who doesn't yet know how a waiter workers, is the waiter, and Mr. Krabs, who says he once served on the S.S. Gourmet, is the chef. However, things do not go well; Patrick is beating up the hat rack because it won't "give" him its hat, Mr. Krabs makes terrible food and says that he worked as a janitor on the Gourmet and was the head chef on the S.S. Diarrhea, and SpongeBob can't handle the copy of "How To Become A Fancy Waiter in Less Than 20 Minutes" that Squidward gave him. Squidward tells SpongeBob to clear his mind of "everything that doesn't have to do with fine dining and breathing". SpongeBob's mind, which is metaphorically portrayed as an office, is operated by smaller SpongeBobs. Their boss's assistant tells them that he's just got an order: Dump everything that isn't about fine dining. They begin to get rid of (most of) all documents, which represent SpongeBob's knowledge, until SpongeBob just stares into empty space and doesn't respond to anything.
Squidward runs outside and bumps into Squilliam, who is just about to enter. They both go inside, and see that the Krusty Krab has been transformed into a very fancy five-star restaurant. After sending all the customers to their tables, SpongeBob tells Squidward that he did all of this, and that he has tied up Patrick and Mr. Krabs in the kitchen. After his meal, Squilliam admits that he is impressed and asks SpongeBob what his name is. However, SpongeBob cannot remember his name, having discarded it along with everything else, and inside his mind, all of the little SpongeBobs are trying to find his name, which ultimately results in his brain snapping in half. SpongeBob goes insane, destroying the fancy restaurant environment and revealing the Krusty Krab for what it really is. Squilliam finds out that Squidward actually is a cashier, humiliating him. However, Squilliam then "admits" that he's also a cashier too before revealing that he was just kidding and that he is "filthy stinkin' rich!" He and his crowd leave the restaurant to ride in his "balloon/casino," leaving Squidward dejected and defeated once again, but not before Mr. Krabs plays him a sad song in the World's Smallest Violin, which annoys him.
When Squilliam says that he wants to come to the restaurant that night, Squidward (who had already said that it was a 5-Star Restaurant) could have said that they were booked up, as most 5-star restaurants call for reservations. However, Squilliam could have been suspicious by this.
In the Bahasa Malaysia version of this episode, when SpongeBob greets the customer, he says "Your butt want to eat rice?"
This is the first time Fred wears the same clothes as SpongeBob (brown trousers, black belt and a white shirt). Fred would again wear the same clothes as SpongeBob in "The Sponge Who Could Fly," however for some reason, he's purple.
While SpongeBob's mind is being cleared, one of the sheets being shredded was titled, "Spice Garden Tips." Interestingly, SpongeBob's spice garden was mentioned in the partner episode, "No Weenies Allowed."
Three parts of this episode have become popular on YouTube: the first being Patrick saying "may I take your hat sir?," "hommina," and "T-t-t-t-t-t-tonight?"
Apparently, Patrick wants to join the army (the corps). This could be a contradiction as he is normally lazy while the army is extremely active. However, Patrick did say that he thought the corps would help him straighten out his life.
The scene when Squidward tells SpongeBob to clear his mind might be a parody to the Total Recall scene.
Running Gag:Mr. Krabs playing "the world's smallest violin."
This also became an internet meme.
When Mr. Krabs messes up the peas and the appetizer and Squidward interrogates him, the two speak as though Mr. Krabs had told Squidward that he was the 'Head Chef' on the S.S. Gourmet. This is not true, as their first conversation regarding the S.S. Gourmet was Squidward merely asking Mr. Krabs if he had "once served" on it and then jumping to the conclusion that he had been the chef.
When Squidward asks SpongeBob how he transformed the Krusty Krab, Squidward addresses SpongeBob by name. SpongeBob replies, as if he already knows his name. However, toward the end of the episode, when Squilliam asks him his name, SpongeBob's name is "thrown out" of his mind. This conundrum would put a major loophole in the entire storyline. However, it could be possible that he just forgot his name in between these events.
When Squilliam "admits" he's a cashier, Mr. Krabs is wearing a tuxedo rather than the outfit he was wearing throughout the episode. This also happens at the very end. There is a possibility that SpongeBob dressed him up.
When Squilliam asks SpongeBob for his name, Squidward could have simply said to Squilliam "His name is SpongeBob SquarePants" or just told SpongeBob what his name is, that way SpongeBob would not have destroyed the place. However, Squidward did not know that this would happen, so there is no way he could have prevented it.
This episode makes two references to its sister episode, "No Weenies Allowed". One is that Patrick acts like a weenie, which is a reference to Weenie Hut Jrs, Super Weenie Hut Jrs, and Weenie Hut General. The other is that one of the things that is thrown out is "Spice Garden tips", which is a reference to the line, "I'll have you know I stubbed my toe last week while watering my spice garden, and I only cried for twenty minutes."
"Hommina hommina hommina" is Ralph Kramden's catch phrase in the TV show The Honeymooners.
When Squidward encounters Squilliam he only has a few friends with him, when Squilliam says, "We should all come," he has a lot more friends.
When Squidward turns his head over to Squilliam he is coming to the left, when Squidward puts his hat in the bin, Squilliam is to the right.
When Squilliam arrives at Squidward's "five-star restaurant," it is sunset, but when he is eating his meal, it is nighttime. But at the end of the episode, after Squidward says, "WOULD YOU GET OUT OF HERE?!," it is daytime.
When Mr. Krabs is playing the world's smallest violin after the Krusty Krab reverts to its original self, his eye stalks are white instead of pale green.
Squidward tried to imagine Squilliam in his underwear, but neither he nor Squilliam wears underwear, or even pants at all.
Judging by the width of the How to Become a Fancy Waiter in Less Than 20 Minutes book, it should take longer than 20 minutes to read this entire manual.
Before Squilliam enters the restaurant, the windows of the Krusty Krab are visible, but inside, there is wallpaper covering the windows.
The "appetizer" destroys the door to the kitchen, but it is shown to be intact at the end of the episode.
SpongeBob knew nothing except for fine dining and breathing, but managed to tie and gag Mr. Krabs and Patrick.
When Patrick and Mr. Krabs are bound and gagged in back, Mr. Krabs' legs aren't tied and eyes are. But, when he comes from the kitchen, his eyes aren't tied and legs are.
Mr. Krabs slides instead of walking at the end.
However, this was most likely used for comedic effect.
Some of the people in Squilliam's group don't have bottom halves.
Dish Network accidentally lists this episode as "Squillliam Returns" adding an extra L.
When Patrick and Mr. Krabs are bound and gagged in the back, Patrick has a rope tied around his forehead, but when he comes out, there's not any rope.
When Mr. Krabs comes out from the back, he has no arms. It is unlikely that his hands were tied behind his back, because before that, it shows that SpongeBob tied his hands on his stomach.
