In Brief: Squidward comes up with a holiday for SpongeBob and Patrick, hoping it will prevent them from disappointing a realtor who plans to sell his house.

Story: SpongeBob and Patrick throw a birthday party for Squidward on a morning that isn't his birthday. When he gets them out of the house, Squidward decides he's had enough and wants to move to a new home. He contacts a realtor, who tells him she could easily sell his house if it isn't surrounded by annoying neighbors. Squidward knows that nobody would want to be surrounded by Patrick and SpongeBob, so he needs a plan that will get his house sold.

The next morning, Squidward tells SpongeBob about a new holiday that he invented: Opposite Day. On this day, he must act the opposite of how he usually does. Now that Squidward convinced SpongeBob to be out of the way, he feels confident that his house can be sold.

SpongeBob tells Patrick about Opposite Day, and the two act the opposite of usual. They even destroy SpongeBob's house. Squidward thinks the realtor won't like seeing his neighbor's house in bad shape, so he starts working on fixing it. Meanwhile, Patrick and SpongeBob decide to act like Squidward and live in his house.

As Squidward works on SpongeBob's house, the realtor comes. In Squidward's home, SpongeBob acts as Squidward and tells negative things about the place (he's acts opposite of her asking for positive things) and terrorizes her with horrible clarinet playing. Squidward comes to the house late and discovers SpongeBob and Patrick acting as him. He tries to convince the realtor that he's the real Squidward, but she gets frustrated and leaves on him, without agreeing to sell the house.
