"Opposite Day" is a SpongeBob SquarePants episode from season 1. In this episode, Squidward tells SpongeBob and Patrick that it is Opposite Day, and everything goes fine until the duo decides to take the holiday to the next level.



The episode starts by showing Squidward still asleep, only to be woken up and then 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 having had enough of SpongeBob and Patrick, decides to move out of Bikini Bottom the next day. That afternoon, he calls Bikini Realty to arrange for his house to be sold, so that he may move out of the neighborhood. 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 thinks that whatever a good neighbor does, SpongeBob and Patrick do the opposite, which gives him an idea.

A now-goofy Squidward tells SpongeBob that it is Opposite Day the next morning, and that everyone must act opposite to how they usually act. A now-grumpy SpongeBob believes him, and informs Patrick, who stops breathing, 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.

"I'm Squidward, I'm Squidward, I'm Squidward, Squidward, Squidward, Squidward!"

While Squidward is still fixing SpongeBob's house, the real estate agent arrives, and SpongeBob and Patrick both pretend to be like 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 the realtor, who, upon hearing that he is "Squidward" as well, finally realizes throughout everything and berates them of intentionally messing with her for it.

"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, which is the last straw for her that she angrily storms out and officially declined Squidward's house of being sold. Squidward begs the realtor to sell his house, but she refuses stating she wouldn't sell the house if he was the "last Squidward to exist on Earth" and then she storms off.

SpongeBob and Patrick tells Squidward "Happy Opposite Day." A furious Squidward shows SpongeBob and Patrick how much he "likes" (hates) them by attempting to run them over with the bulldozer, scaring SpongeBob and Patrick out of their wits as he is now on the warpath against them. SpongeBob then asks Patrick if he ever feels that Squidward likes them too much before the episode ends.

  • "Opposite Day" was ranked #54 during the Best Day Ever event from November 9–10, 2006.



  • When SpongeBob and Patrick are talking backwards, in reverse they are saying: "Hey, Patrick," "I give up," and "To get to the opposite side." The original closed-captions said "(speaking gibberish)."
  • This is the first episode where Gary has said something other than "Meow"; he barks like a dog instead of using his trademark cat meow.
  • This episode marks the first appearance of Squidward's self-portraits.
  • A portion of the episode was used in the 2000 Kids' Choice Awards, but redubbed with new dialogue and a kids' choice green screen background.
  • This is the first episode to use the production music track "Sunny Samoa."
  • This is the first episode where SpongeBob's belt buckle is shown.
  • This is one of the rare times in season 1 where Squidward cries.
  • This is the second time SpongeBob impersonates Squidward. The first time is in "Ripped Pants."
  • Squidward chasing SpongeBob and Patrick with a bulldozer actually shows how much he hates them, which he really does hate them a lot. The exact opposite would be Squidward doing something nice to them like throwing them a party and/or giving them gifts. Naturally, SpongeBob and Patrick think he likes them because of their belief in Opposite Day.
  • Irony: Squidward's visit from the realtor would've been successful if he told Patrick about Opposite Day as well instead of just SpongeBob.
  • In the Russian dub, the line "Kcirtap yeh. Pu evig I. Edis etisoppo eht ot teg ot" was changed to "Кем мы были? Пузырями. Сами надулись и сами лопнули!," which translates to "Who were we? Bubbles. We blew ourselves and popped ourselves!" The line isn't spoken backwards.
    • Also, when SpongeBob shouts "I'm not ready!," he just laughs.
  • In the Bahasa Indonesia dub, instead of speaking backwards, SpongeBob and Patrick are telling the riddle: "Why did the chicken cross the road?"
  • In the Greek dub of the episode when Patrick knocks at SpongeBob's door, both SpongeBob's and Patrick's lines are muted and sound is barely found during their dialogue.
  • This and its' paired episode "Nature Pants" both premiered on Nickelodeon the same day Looney Tunes on Nickelodeon had its' final run on the network.
  • During the Best Day Ever marathon, this episode was paired with "Mermaid Man & Barnacle Boy VI: The Motion Picture."[2]
  • In the Filipino dub, when SpongeBob pretends to be Squidward, he is voiced by Marvil Ramirez, the voice of Squidward, instead of the usual Rudolf Baldonado. Patrick however is still voiced by Jojo Galvez.


A glitched rainbow frame (only shown in certain releases)

  • During the "Pin the Tail on the Seahorse" scene, the tail that Squidward is holding is not a seahorse's tail. Also, the image of the seahorse already has a tail.
  • When SpongeBob and Patrick leave the house, the green piece of confetti becomes blue when it lands on the ground.
  • When Squidward's house is seen by itself after Squidward says, "Opposite..." SpongeBob and Patrick's houses don't appear. Also, in that same scene, an ear on Squidward's house has a window, then it disappears.
  • When Squidward starts to rebuild SpongeBob's house, the lower part of his body is not colored in.
  • When SpongeBob puts the belt around his head, the buckle and the piece of belt that goes through it disappears.
  • When Patrick first sings "I'm Squidward, I'm Squidward, Squidward, Squidward, Squidward" the flowers on his pants are almost black, but in the next shot they are dark purple - like in other episodes in the first season.
  • When the realtor walks into Squidward's house, Patrick's house cannot be seen.
  • After the realtor leaves, Squidward lays on the ground in shame. In the close up of his face, SpongeBob has his belt around his waist, but it was wrapped around his head.
  • In the Paramount+ release and certain international airings of the episode, right before Patrick dances and sings "I'm Squidward," a rainbow hue can be found in a glitched frame.
