Happy birthday, Squidward!

[cheering]

So long, Squidward! Buh-bye!

It's not my birthday!

That's it! I'm moving out of this neighborhood!

I can sell your home in a heartbeat.

Oh, that's great news because I want to move as soon as possible.

As long as it's not infested with nematodes, or surrounded by troublesome neighbors or something like that.

Oh sure, there's none of that-- Did you say neighbors?

I'll be by tomorrow to check out the house.

See you then!

SpongeBob!

Whatever a good neighbor would do, he does the opposite.

Opposite?

Opposite...

[screaming]

[music playing]

Squidward, you need bed rest.

I'll keep you safe until you're well again.

Oh, I get it.

You don't know what day it is, do you?

It's Opposite Day.

Opposite Day is the one day of the year when you get to act different.

Normally, you're really loud and annoying, so what are you going to be today?

Quiet and out of the way!

Yay!

Yeah! Why don't you get a jump on it?

I love-- I mean, I hate Opposite Day.

[giggling]

I'm not ready!

Nearly noon and not a peep from SpongeBob.

[laughing]

Opposite Day...

SpongeBob, what are you-- Ah!

Hello, Squidward!

Oop, I mean goodbye, Squidward!

If the real estate agency sees that mess, I'll never sell this house.

Isn't it beautiful.

On Opposite Day it is.

[motor running]

Out of the way, SpongeBob!

I don't get it.

I made my house a mess, which was making it clean, which made Squidward clean my yard, but that really means he's messing it up.

But the opposite of clean is filth, which means filth is clean.

That means Squidward is really making my yard a wreck.

But I'd normally wreck my own yard, which means Squidward is being the opposite of Squidward, which means he's SpongeBob!

Ah-ha! I understand everything now.

I must be the opposite of SpongeBob, by being...Squidward.

Hey!

I wanna be opposite too.

Yeah!

After you, Mr. Squidward.

Why, thank you, Mr. Squidward.

Next time it's gonna be Go Jump Off A Cliff Day.

Oh, my! The house is even more beautiful in person.

Hello, Mr.--

Mr. Tentacles?

Yes, please come in.

Now, if you want the sale to go through, you've got to tell me all the positive things about your house.

Positive things, Opposite Day.

I'd love to.

The floor creaks, the roof leaks, there's a terrible draft.

Uh...

And here's the worst room in the house, my gallery.

Oh my, this painting is very nice.

Thank you!

Who's that?

I'd like to introduce you to Mr. Squidward.

Ah, well that's done.

At least SpongeBob has been quiet.

Ah, no!

Stop!

Get away from her!

I hope these two barnacle heads haven't harmed you in any way.

Who are you?

Why, I'm Squidward.

What kind of fool do you take me for?

I wouldn't sell a house for you if you were the last Squidward on earth!

No! No! No!

- Please sell my house. - Never!

Don't leave me here!

[sobbing]

Happy Opposite Day, Squidward!

We hate you!

Let me show you guys how much I hate you.

[screaming]

Patrick, you ever feel that Squidward likes us too much?

Happy Opposite Day!

[laughing]
