At the Krusty Krab, Pearl runs in crying so profusely that her tears begin literally flooding the restaurant. Mr. Krabs asks her what's wrong, and she explains that her prom date has just dumped her, and the prom is tomorrow night. Mr. Krabs offers to take her instead, but she starts crying, causing an earthquake. He then suggests she take Squidward or one of the restaurant's customers to the prom, but she continues crying, which causes the earthquake to become worse. Ultimately, he chooses SpongeBob to be the one to go with her. Pearl doesn't want to be embarrassed by SpongeBob, and begs him to do his best not to. At home, using a magazine as a guide, SpongeBob dresses up and uses extremely long artificial legs to make himself look "long, tan, and handsome" for Pearl. On the night of the prom, things initially work well for SpongeBob and Pearl. However, SpongeBob's costume soon begins malfunctioning, resulting in disaster and severely embarrassing Pearl. SpongeBob, after having broken everything at the prom, runs into the ladies' restroom crying. Pearl, feeling sorry for him, attempts to console him and restore his confidence.
This ultimately succeeds, and Pearl and SpongeBob join the prom dance. They begin doing a dance called "Doing the Sponge," which everyone else soon begins doing. However, this results in many injuries and mass destruction. An angry mob forms and lifts up Pearl and SpongeBob, who think this means that they are popular until the mob throws them out of the building. SpongeBob apologizes, and Pearl says even though it was a disaster, it was really fun. Pearl says goodnight to SpongeBob as she returns home, and tries to get SpongeBob's attention, but as she does so SpongeBob appears to be frozen. Mr. Krabs congratulates SpongeBob on his success at the prom, and the real SpongeBob appears to retrieve his wax dummy of himself (which was seen earlier in the episode), and carries it off, laughing.
At the beginning when SpongeBob makes a Krabby Patty, the patty looks wider than usual. Also, the bottom bun looks smaller and narrower.
All the customers at Krusty Krab during the scene where Mr. Krabs offers them to be Pearl's prom date look identical (they are all Freds).
Pearl's "pizza topping" remark is a reference to anchovies being used as a topping for pizza. At first glance, one would think she's referring to his acne, since "pizza face" is a term for a bad case of acne.
When the people at the dance throw Pearl and SpongeBob out, rather than sounding angry, they sound more like they're cheering. This was done to deceive the audience.
This is the first episode SpongeBob dispenses a drink because he absorbs it. The second episode is "The Slumber Party."
This is the first episode in which SpongeBob and Pearl interact with one another.
When SpongeBob listens to Mr Krabs talking to Pearl in his office, the outside door is a wooden door instead of the usual metal door.
When SpongeBob asks what's wrong, there is a window on the door that goes to Mr. Krabs' office, rather than an anchor, but the anchor is back in a later shot.
In one scene, when talking to Gary, SpongeBob clearly has lighter than usual blue eyes. This error goes on until the middle of the prom.
When SpongeBob gets ready for prom he wears braces, but after that and for the rest of the episode he isn't wearing them.
In the shot, immediately after SpongeBob's legs malfunction, they are back to normal.
In the scene where SpongeBob is coming to Mr. Krabs' house before the prom, sounds of him struggling to walk can be heard, though his legs can clearly be seen through the window, not having moved the whole time.
One of Pearl's friends is seen on a stretcher during Doing the Sponge, but when the teenagers throw SpongeBob and Pearl out of the prom, she is one of the teens who threw them out.
During the Doing the Sponge song, another of Pearl's friends is seen sitting on the floor with her arm in a cast. When the song ends, she throws Pearl and SpongeBob out, and the cast on her arm is missing.
In some scenes, Pearl's rubber band was the same color as her hair.
In the credits, Peter Strauss, writer of Doing the Sponge song, is credited as "Saltpeter."
This same error happened in Ripped Pants for the "I Ripped My Pants" song.
On some of the DVDs like "Lost at Sea," in the description, it says "tall dark and handsome" instead of what Pearl says "long tan and handsome."
