The episode begins at the Krusty Krab with Mr. Krabs getting a notice from the Fry Cook Union that since SpongeBob has accumulated too much vacation time, he needs to take a vacation. SpongeBob goes home quickly afterwards, but the next day, he goes back to the Krusty Krab again. Mr. Krabs reminds SpongeBob that he's on vacation and also gets Patrick to be SpongeBob's replacement fry cook for the time being.
SpongeBob is tired of being at home, so he decides to go to the Krusty Krab as a customer. Mr. Krabs accepts this, but when he sees that he's trying to help Patrick, he kicks him out again. SpongeBob still misses the Krusty Krab, so he tries several more attempts at getting to the Krusty Krab, only to fail each time.
Eventually, Mr. Krabs is tired of this, so he sends SpongeBob to the middle of a forest. SpongeBob thinks that Mr. Krabs is trying to replace him permanently, so he goes into Patrick's house to scare him out of being a fry cook. At the Krusty Krab, Mr. Krabs thinks Patrick is cooking Krabby Patties, but sees that it was just SpongeBob in a Patrick outfit. It turns out SpongeBob has used up his vacation time, so SpongeBob continues working at the Krusty Krab.
