Plot
Squidward is still asleep, only to be woken up and annoyed by SpongeBob and Patrick, who came into his house to throw a surprise birthday party for him. When they leave, he shouts that it isn't his birthday and callsPatty Rechid from "Bikini Bottom Realty" to arrange for his house to be sold, so that he may move out of Bikini Bottom. He is warned that, if his home is surrounded by bad neighbors, the house may not be sold. Squidward is convinced that SpongeBob and Patrick may ruin his chances of selling his house.

Squidward tells SpongeBob that it is "Opposite Day" in the morning, and that everyone must act opposite to how they usually act. SpongeBob believes him, and informs Patrick, who forces himself to stop exhaling, until SpongeBob exclaims, "not that opposite!" A montage of the two doing "opposite" things, such as talking backwards and acting as Gary's pets, is then shown.

Squidward's plot soon begins to backfire on him. SpongeBob "fixes" (damages) his house, and a shocked Squidward cleans the debris with a bulldozer. SpongeBob concludes that Squidward is acting like him, and he must therefore act like Squidward. While Squidward is still fixing SpongeBob' house, Patty arrives, and 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. When Squidward realizes what is going on, he rushes to his house and attempts to explain the situation to Patty, who, upon hearing that he is "Squidward" as well, finally sees through his game and accuses them of intentionally messing with her:"WHAT KIND OF FOOL DO YOU TAKE ME FOR?! HE'S SQUIDWARD! HE'S SQUIDWARD! YOU'RE SQUIDWARD! I'M SQUIDWARD! ARE THERE ANY OTHER SQUIDWARDS I SHOULD KNOW ABOUT?!". Gary comes in with a pickle on his face, resembling Squidward's large nose. He meows with a Squidward-style voice, and she leaves. Squidward begs Patty to sells his house, only for her to replies "I WON'T SELL YOUR HOUSE EVEN IF YOU'RE THE LAST SQUIDWARD ON EARTH!!". A furious Squidward shows SpongeBob and Patrick how much he "hates" (Squidward was not being sarcastic, although SpongeBob and Patrick did) them by attempting to run them over with a bulldozer, scaring SpongeBob and Patrick out of their wits as he is now on the warpath against them.
