Opposite Day: Squidward plans to move out of Bikini Bottom after being annoyed by SpongeBob and Patrick. However, he is warned by the real estate broker that if his home is surrounded by bad neighbors, the house cannot be sold. Squidward tells SpongeBob that it is "Opposite Day", and that everyone must act opposite to how they usually act. SpongeBob later tells Patrick about Opposite Day. When Squidward is busy and the real estate broker arrives, SpongeBob and Patrick both pretend to be Squidward, giving her a tour of the house, while describing it negatively and doing the opposite of what she asks. Then, the real Squidward arrives and begs the broker to sell his house, but, feeling deceived, she refuses, leaving Squidward stuck where he is. In response, Squidward literally tries to run over the duo with a bulldozer, while sarcastically saying "Happy Opposite Day."
