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 suggests taking himself, but she starts crying, causing an earthquake. He then suggest he takes 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 that SpongeBob should be the one that has 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 "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.
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).
MY LEG: When the music is playing, everyone struggles to dance as the prom is ruined.
At nine minutes and thirty-four seconds into the episode, there is a reference to the film "Attack of the Killer Tomatoes" (1978), when a girl in a white dress is chased by a giant apple.
At the beginning when SpongeBob makes a Krabby Patty, the patty looks wider than usual. Also, the bottom bun looks smaller and narrower.
This is the first time SpongeBob dispenses a drink because he absorbs it. The second time will be in "The Slumber Party."
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.
The scene where Pearl tries to console a hysterical SpongeBob through the door is a reference to a similar scene from the All in The Family episode, "Stale Mates."
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.
When Pearl floods the Krusty Krab with her tears, the customers are thrown up into the air. When they fall, Fred can be seen falling twice, one on the floor and one on Mr. Krabs.
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.
One of Pearl's friends is seen on a stretcher during 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 that same scene, another of Pearl's friends is sitting on the floor with her arm in a cast. She also throws Pearl and SpongeBob out, and the cast is missing.
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.
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 some scenes, Pearl's rubber band was the same color as her hair.
When SpongeBob and Pearl are getting thrown out, the sign says "Prom Nite" instead of "Prom Night."
In some of the DVDs like "Lost at Sea," on the description: It says "long dark and handsome" instead of what Pearl says "long tan and handsome."
