At the Krusty Krab, it is Employee Brotherhood Day. Squidward does not know that on Employee Brotherhood Day, all employees must exchange gifts that they made themselves, and SpongeBob then gives Squidward a sweater made out of his eyelashes. When Squidward scoffs at his heartfelt gift, SpongeBob begins to cry copiously, eventually handing Squidward a sweater made from his own tears.
Squidward wishes he could buy a gift instead of make one, and sees a group of pirates outside with a sack of pies. He goes outside and the pirates say that they are just pie shaped bombs, but after Squidward offers to buy one, one of the pirates says they were kidding, and Squidward buys a pie for $25. He lies to Mr. Krabs, saying that he made it. Mr. Krabs says he has to inspect it, and eat a bit to see that it is not horrible. He breaks a tiny bit off the crust and says, "This would go great with some milk!" When he trips over and the bit of the pie explodes and wrecks the back of the Krusty Krab, Squidward and Mr. Krabs are blown away. When they arrive at the Krusty Krab, SpongeBob acts as if he ate the pie, but it is unknown if he even ate anything. Mr. Krabs tells Squidward that the pie would explode around sunset when it reached SpongeBob's lower intestine, so Squidward decides to make SpongeBob's remaining hours fun. After being asked what the most fun things he likes to do are, SpongeBob presents a list of the most fun things he likes to do.
The last activity SpongeBob planned, is watching the sunset with Squidward. Squidward remembers Mr. Krabs warning about the pie settling in SpongeBob's lower intestine at sunset and nervously agrees to participate. Squidward builds a brick wall between them and disguises his worry. SpongeBob mentions that if he were to die in some sort of fiery explosion due to the carelessness of a friend, this sunset would be what he would want to see as Squidward begins to tear up. SpongeBob lets out a quiet burp, saying something just hit his lower intestine but can't quite tell what flavor it was. As the sun slowly makes it's way past the horizon, SpongeBob begins a five second countdown, letting Squidward finish the count. At the end of the first count, the sun still hasn't fully set, SpongeBob says they may have started too early. Squidward, even more nervous, begins counting down. When he hits "two" the sun finally sets, and an explosion happens on the opposite side of the wall. Squidward breaks down into tears, thankful he was able to make SpongeBob's last few hours meaningful and complimenting himself on being such a good person. Another explosion occurs, which knocks the wall down, crushing Squidward. Squidward pulls himself out from underneath the wall, and, to his confusion, finds that SpongeBob is still alive and blowing bubble bombs. Squidward angrily berates SpongeBob that he was supposed to explode after eating the pie. At first Spongebob is confused, but then remembers the pie he was saving in his pants pocket. He mentions that he was saving it for them to share. As he walks over to Squidward he trips over a nearby rock and accidentally flings the pie directly at his face. The resulting collision triggers the bomb inside the pie, demolishing all of Bikini Bottom in a nuclear explosion. Squidward miraculously survives, uttering a very plain "Ouch."
Footage of the Operation Crossroads' Baker atomic test is used to represent the explosion near the end of the episode. The test was conducted at Bikini Atoll. The series is set in the fictional city of Bikini Bottom, located beneath Bikini Atoll.
Squidward appears driving a boatmobile in this episode, but he frequently appears using his bicycle or walking to work. However, Squidward appears using another boat in "Boating Buddies."
There is a bumper sticker on Squidward's boatmobile that reads, "Don't ask me about my day."
When SpongeBob is sliding his body across the Krusty Krab glass window, he leaves a trail of clearness with part of the glass turning lighter. It's implied here that SpongeBob's body is cleaning the glass as he is a sponge.
Mr. Krabs mentioned he had seen this "11 times" before. The bomb was purchased from pirates, and it is implied that Mr. Krabs witnessed 11 comrades in the navy die from pirate attacks during his time in the war.
SpongeBob's things to do for his friendship list:
Show Squidward (to everyone in town)
(Show Squidward to everyone in town) in a salmon suit
When SpongeBob was doing open-heart surgery on Squidward, it was the first time blood appears on the show. Squidward also has a blood scene in "House Fancy."
This episode was originally going to be rated something higher than TV-Y7 because of the blood shown during the heart surgery, but somehow SpongeBob SquarePants creators and Nickelodeon got around it. It might have been because the heart and the blood were fake.
SpongeBob was rated TV-Y back then; blood is uncommon in shows with this rating unless the episode's about getting a wound.
The scene where SpongeBob yells, "Gary! You are gonna finish the dessert and you are gonna like it!" has become a popular internet meme.
It is unknown how Squidward and the citizens of Bikini Bottom recovered from the pie explosion.
The explosion at the end of this episode has become a popular meme on the Internet and a very popular YouTube Poop source.
For some reason, on the YTV airings of this episode, the title card isn't shown.
In the Polish dub, the episode's title is "Bombowe ciasto" translating to "The Bomb Pie."
SpongeBob also said that he and Squidward will finish the book by October, not January.
In German, the episode is called "Die Kuchen-Bombe" translating to "The Pie Bomb," "Employees Brotherhood Day" translates to "Alle-Angestellten-Sind Freunde Tag" "All Employees are Friends Day,' the characters' voice actors translate the writing themselves: "Do Not Ask Me About My Day" becomes "Frag Mich Nicht Wie's Mir Geht" translating to "Do Not Ask Me How I Am."
In the Croatian dub, the episode's name is "Ubojita Pita" translating to "Deadly Pie."
In the beginning scene where Squidward is shown playing the piano, the note he plays that makes the ringing sound is actually a D, while it is animated to be an F.
When Squidward and Mr. Krabs walked to the door, Mr. Krabs' eyebrows disappeared.
After Squidward scolds Mr. Krabs for making Employee Brotherhood Day, when he says "...that guy!," Mr. Krabs is seen clearly with no legs. This is most likely an animation error. Also in that same scene, Squidward only has two legs. This error also occurred in "Christmas Who?"
When SpongeBob says "eyelashes," his forehead is noticeably higher. It also shows the lighter part, which is where his eyebrows are supposed to be not his eyelashes.
The Krusty Krab appears and disappears in the background when Squidward talks with the pirates.
Before the pie piece exploded at the Krusty Krab, Squidward's Krusty Krab Employee Hat was on, but after the explosion, he did not have his hat. His employee hat probably blew away off-screen from the explosion.
When Mr. Krabs took a small piece of the pie and said that it would be more delicious with some milk, when the small piece of pie exploded after he tripped down, the place where the small pie exploded strangely moved behind Mr. Krabs' counter.
When Mr. Krabs drops a small piece of pie on the barrel, it causes a violent explosion in the Krusty Krab. However, when Squidward carelessly dropped the pie onto Mr. Krab's desk, it caused to no reaction or explosion. This could be that the tin protected the pie, since Mr. Krabs dropped an exposed piece of it and SpongeBob dropped in in Squidward's face.
After Squidward and Mr. Krabs are blown out of the Krusty Krab and they see the pie is gone, the wall was strangely blown inwards instead of outwards.
When Mr. Krabs tries to eat a piece of the pie, he left a small hole in the pie. When SpongeBob takes it out from his pocket and walks to Squidward, the hole was gone.
The open-heart surgery appears to come after the trade faces activity, but it was also written after the knock knock jokes.
Because Squidward is an octopus, his blood in the open-heart surgery should have been blue.
When SpongeBob checks some of the things off the list, the list glitches and overlaps itself, seeming to fold.
The order of things to do on the list also changes multiple times throughout the episode.
The bandage on Squidward's chest disappears when he and SpongeBob go watch the sunset.
When the brick wall that is separating Squidward Tentacles and SpongeBob SquarePants during the sunset breaks down after the bubble bomb explosion, a brick flies out of it. During the second bubble explosion, the brick is suddenly back in the wall when it is in the air, and disappears again when it falls on top of Squidward.
When SpongeBob says, "Well since we finished everything on the list, I thought I'd make up a new one," the closed captions say, "Well since we finished everything on the list I made a new one."
There was no rock near SpongeBob when Squidward was yelling at him. When SpongeBob said, "Oh! You mean this pie!" the screen eased in to the pie. When it zoomed out, a rock appeared near SpongeBob and this, he tripped.
