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 is watching the sunset together. After remembering SpongeBob explodes at sunset, Squidward builds a brick wall between them and gets even more nervous and sad than before. At sunset, there is an explosion, but it is actually a bubble that SpongeBob blew (It is in the shape of a bomb and explodes). There is another explosion, which knocks the wall down, crushing Squidward. Squidward comes out and finds that SpongeBob is still alive. He says he is supposed to explode after eating the pie. SpongeBob does not seem to remember, then says 'Oh, you mean this pie!" He takes the explosive pie out of his pocket and says that he was saving it for them to share. He prepares to eat it even though Squidward just said it was a bomb. When he trips over, the bomb hits Squidward in his face and goes off, demolishing all of Bikini Bottom in a nuclear explosion. Squidward miraculously survives, uttering a very plain "Ow".
Footage of the Operation Crossroads nuclear 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.
This episode marks the first time that we see a side of Squidward we have never seen before. It shows that even though he says multiple in the series he absolutely hates him, Squidward cares about SpongeBob enough to make sure he dies happy. The second time Squidward does not hate SpongeBob is in Can You Spare a Dime? for a while.
When the brick wall that is separating Squidward and SpongeBob 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.
Squidward appears driving a boatmobile in this episode, but he frequently appears using his bicycle or walking to work. However, Squidward apepars using another boat in Boating Buddies.
It's unkown how Squidward and citizens of Bikini Bottom recovered from the pie explosion.
There is a bumper sticker on Squidward's boatmobile that reads, "Don't ask me about my day".
When SpongeBob was doing open-heart surgery on Squidward, it was the first time blood appears.
Like Patrick before him in Suds, SpongeBob impersonates a doctor. However, he goes one-step further by playing the role of heart surgeon. Of course, impersonating a doctor is illegal. Sandy says Patrick should be arrested for impersonating a doctor in Suds, but Squidward does not say anything about it in this episode.
The explosion at the end of this episode has become a popular meme on the Internet and a very popular YouTube Poop source.
This episode was going to be rated something higher than TV-Y7 because of the blood shown during the heart surgery, but somehow SpongeBob creators got around it. It might have been because the heart blood were fake.
In Polish version, this episode called Bombowe ciasto which means Bomb Pie.
When Squidward and Mr. Krabs walked to the door, Mr. Krabs' eyebrows disappeared.
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.
After Squidward and Mr. Krabs are blown out of the Krusty Krab and they see the pie is gone, the wall is strangely blown inwards instead of outwards.
When SpongeBob checks some of the things off the list, the list glitches and overlaps itself, seeming to fold.
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.
The bandage on Squidward's chest disappears when he and SpongeBob go watch the sunset.
When Mr. Krabs tries to eat a piece of the pie, he left a small hole in the pie, but when SpongeBob takes it out from his pocket and walks to Squidward the hole is gone.
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 thus, he tripped.
At the end of the SpongeBob checking off activities and laughing the last thing you see him check off is "in a salmon suit" even though that was the second thing Squidward and SpongeBob did [This might be a joke].
The open-heart surgery appears to come after the trade faces activity, but it was also written after the knock knock jokes.
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.
The Krusty Krab appears and disappears in the background when Squidward talks with the pirates.
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.
Before the pie piece exploded at the Krusty Krab, Squidward had his hat on, but after the explosion, He did not have his hat. His hat probably blew away from the explosion.
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."
On SpongeBob's list, one of the things is "Introduce friend in a salmon suit". However, when SpongeBob checks off juggling, he checks off to introduce friend in a salmon suit a second time, when this was already done.
