[Patrick's house is shaking. SpongeBob knocks on it. Every time he does, it closes. He opens it himself. Patrick is cleaning frantically. He feather-dusts SpongeBob.]

Patrick: Need... furniture! [makes a lamp post model out of the sand, then licks it to make it remain in shape; he then makes a sand drawer, television, stool, and a couch. The whole time he is still frantically mumbling.]

SpongeBob: Patrick, what's with the home improvement? [Patrick barks like a dog and continues to clean] Hey, Patrick!

Patrick: Ooh, sweep, sweep! [sweeps around the walls of his house and the air]

SpongeBob: Well, Patrick, I came over to see if you wanted to go jellyfishing, but I can see you're busy having an episode.

Patrick: [stops cleaning and his face turns mad] You know something, SpongeBob? It's just all fun and games for you. Nothing really matters. [imitates SpongeBob] "Oh, let's go jellyfishing! We don't have any work to do!" Life is just a big bowl of fancy assorted cashews, and nobody has anything to dust or to clean or to wipe! Or fabricate!

SpongeBob: But, Patrick, the only thing I've ever seen you clean is your plate.

Patrick: [snaps out of being angry and starts crying] I don't know what to do, SpongeBob. You gotta help me!

SpongeBob: [gasps] Patrick! You forgot how to eat again! Come on, we'll get the funnel.

Patrick: No, it's not that, SpongeBob. It's worse.

SpongeBob: Darn, I like the funnel. Well, what is it, then?

Patrick: Look! [takes out a rolled-up flashcard from his belly button]

SpongeBob: Hey, a note! [A sixteenth note is shown]

Patrick: Yeah, but turn it over, there's a letter. [The letter B is shown]

SpongeBob: You're right!

Patrick: And I got this message from my parents. [hands out a small message]

SpongeBob: Your parents? [reads the message out loud] "Dear Patrick, your mom and I are coming out tomorrow for Starfish Day. Please try to remember, but don't try too hard, or you'll hurt yourself like last time. Love, Daddy."

Patrick: SpongeBob, my parents think I'm dumber than a sack of diapers.

SpongeBob: No, they don't, Patrick. Parents just like to push your buttons. Like this! [pushes Patrick's nipples and his eyes elongate] Nee!

Patrick: [laughs] That always cheers me up. [his eyes go back to normal] But not today.

SpongeBob: Patrick, if your parents think you're dumb, then they must not know what dumb really is.

Patrick: But don't they watch television?

SpongeBob: That's what I'm saying, Pat! If your parents got to meet a real dummy, they'd realize what a genius you really are!

Patrick: But don't geniuses live in a lamp? And besides, we don't know any dumb people.

SpongeBob: Don't worry, Patrick! I'll be the dummy! When your parents see how dumb I act, they'll think you're the smartest guy ever!

Patrick: Math is power!

[Bubble transition to the next day. Patrick is in front of his mirror]

Patrick: A, B, C, D, E, F, G... [Doorbell rings] Oh! H, I, J, K, L, M, N, O...!

Janet: Should I get the bullhorn again, Marty?

Patrick: W, X, Y, and Z! [Marty doesn't realize the door has been opened and knocks on Patrick's head] Hi, Mom. Hi, Dad.

Marty: Son, You recognized us this time.

Patrick: Why wouldn't I recognize my own parents?

Marty: You never were a bright one. [Patrick groans. Marty laughs] Well, aren't you gonna show us inside?

Janet: He probably forgot where it is.

Patrick: Well, I know where it...

Marty: Oh, let me lead the way so we don't get lost. [Patrick, Marty, and Janet hold hands] Huh? Hold hands now! [inside the house] Okay, we're almost there! Let go on three. One... two... three! [Marty and Janet let go of Patrick's hands on three]

Janet: Good job!

Marty and Janet: Pats for Patrick! [both laugh as Patrick looks annoyed]

Patrick: I'll go get the beverages. [leaves, then comes back with a tray with three drinks on it]

Marty: Wow, son. You put the drinks in something this time. Ah, son, you must've been working all night to put these together for us.

Janet and Marty: We love you. [both kiss Patrick as he looks even more annoyed and groans]

Patrick: [Doorbell rings] Hooray, the idiot's here! I mean, I'll get it.

[Outside, SpongeBob is putting on his karate helmet]

SpongeBob: Protective helmet, check.

Gary: Meow.

SpongeBob: I'm supposed to look stupid, Gary!

Gary: Meow? [goes back to SpongeBob's house]

SpongeBob: What could go wrong? [Patrick's rock opens]

Patrick: What a surprise.

SpongeBob: Hi.

Patrick: Mom, Dad, meet my neighbor, SpongeBob.

SpongeBob: Hi.

Marty: Hello there!

Janet: How do you do?

SpongeBob: Hi. [walks to Patrick's parents]

Marty: Put 'er there. [SpongeBob puts a doll on his hand]

Doll: Mama! Mama!

Patrick: He means "shake." [SpongeBob shakes his entire body] No, SpongeBob, no! Shake hands! [SpongeBob shakes both his hands] No, SpongeBob. Grab my dad's hand. [puts both his hands and his left leg on Marty's hand] Grab it with only one hand! [puts his left leg and hand down] Good boy! Now, move your arm up and down. [SpongeBob moves his shoulder up and down. Patrick giggles]

Janet: So, SpongeBob. Do you live nearby?

SpongeBob: Hi.

Patrick: No, SpongeBob. Show them your house. [SpongeBob pulls up his pants and reveals a blouse] No, not your blouse, Your house. [SpongeBob screams and runs over to his house. He runs into the shell and gets stuck]

Janet: He lives in a fruit?

Marty: That's unhealthy.

[Patrick tries hard not to laugh but he sweats]

Patrick: [giggles] Hey, SpongeBob! You wanna stay for dinner?

SpongeBob: [babbling like an idiot]

[Later, Patrick, Marty, and Janet are watching television while eating TV dinners]

Marty: Does he always do that after he eats?

Patrick: Only on Wednesday. [pan over to SpongeBob pushing his nose to reveal his underwear. When he lets go, his pants pull up by themselves. This is repeated a few times. SpongeBob makes a buzzer sound after that. Patrick giggles]

Marty: [starts giggling with Patrick] Uh, Patrick, I think your friend might be broken.

Patrick: Yeah. And it would take more than some masking tape to fix that guy. [SpongeBob balances on his nose while making a fire truck siren sound. Makes other various sounds, including a cat yowl sound]

Marty: Whoa! Is he gonna be okay? [seal barks]

Patrick: Oh, that's nothing. [dolphin chirps] You should see him in the morning prancing around yelling "I'm ready! I'm ready! I'm ready!" [rooster crows] He drives all the neighbors crazy! [horn sounds] Why, just the other day, our neighbor Squidward was... [SpongeBob jumps backwards over Patrick, Janet, and Marty while making an elephant trumpet sound, then he crashes on the floor] ...was really no help for him. [SpongeBob makes imprints of his front and back twice on the wall] I mean, look at the way he's dressed. Only somebody with holes drilled in their head would wear that stuff. And how about his shape? I mean, I've heard of barrel-chested, [shows closeup of SpongeBob's pants] but never box-chested! [Janet, Marty, and Patrick laugh, but SpongeBob frowns] Hey, SpongeBob, do you have any mascara I could borrow? [makes his eyebrows sound like elastic rubber bands]

Marty: [chuckles] The boy wears make-up?

Janet: What a card! [everyone laughs, except SpongeBob, now very annoyed]

SpongeBob: [confused] Hey, Patrick! Patrick!

Patrick: Aw, [points at SpongeBob] he said my name.

Marty: Wow, how'd you train him to do that?

[Patrick, Janet, and Marty all laugh, while SpongeBob is mad. He bites Patrick's finger]

Patrick: Ow! He bit me.

SpongeBob: Patrick, meet me in the kitchen!

Patrick: Oh, I guess the dummy wants to have a private conversation. [Janet and Marty laugh] A dumb one! [they laugh again, as SpongeBob and Patrick enter the kitchen] So, what's on your mind? Oh, wait, I already know the answer. Nothing! [laughs very hard] See, that's funny. 'Cause you're dumb!

SpongeBob: Patrick, could you let up on the insults just a little bit?

Patrick: Oh, were those too complicated for you? I'll try dumb-ing them down a bit.

SpongeBob: Patrick, I get the feeling that you think I really am dumb! [glances at Patrick's T-shirt, "I'M WITH THE DUMMY" with an arrow pointing towards SpongeBob]

Patrick: That's just what I'd expect you to say. Dumb people are always blissfully unaware of how dumb they really are. [drools]

SpongeBob: I'm only pretending to be dumb! It was our plan, remember?!

Patrick: Oh, SpongeBob, if only you could see how stupid you sound right now, [SpongeBob is shocked] with your talk of imaginary plans... Tell you what. You've caught me at a good mood. I'll humor you. Go on, go out there and act "smart" for everyone.

SpongeBob: Okay, I will! [takes off his helmet and gives it to Patrick]

Patrick: [puts on the helmet] And don't worry, I'll keep this warm for ya.

SpongeBob: [in front of Janet and Marty, clears throat] I have a confession to make. I lied about being stupid. I just acted like a fool so you would appreciate Patrick a little bit more. I know how to talk, and eat, and do laundry. I even separate the darks from the lights. So what do you say we start over and try again? [holds out his hand] Hi! My name is SpongeBob SquarePants, and I am not a dummy.

Marty: [laughs] Amazing. Three minutes in the kitchen and our son has taught him to talk in complete sentences. [puts his right thumb up] Oh, good work, son.

Patrick: [puts his left thumb up] It wasn't easy, dad.

SpongeBob: [sputtering] But... but, but, but, but, but, but...

Janet: It looks like it's time for your next lesson, young man!

SpongeBob: Now listen to me! I'm not dumb! I have a brain! See? Here's a picture of it! [he shows them a small picture of his brain]

Patrick: That must be actual size. [all except SpongeBob laugh]

SpongeBob: No, it's normal size and fully functional! Watch! [writes on Patrick's chalkboard] Two plus two equals four.

Marty: Oh, son. You taught him math, too.

SpongeBob: No!

Marty: And you taught him to sing. [SpongeBob is blabbering and sputtering, then starts tensing up] Oh, now he's short-circuiting. You must have taught him a little too much.

[SpongeBob imagines the three all laughing hard, because of SpongeBob's intelligence. Marty and Janet look at each other and laugh; then the three starfish all do the can-can. He imagines the three popping out of SpongeBob's pores. SpongeBob is inside Janet, who is laughing, inside Marty, who is also laughing, inside Patrick, who is also laughing, inside his eye.]

SpongeBob: [screams, then starts running towards the wall, crashing through the wall outside]

Marty: You know, son, I've always known that when it comes to brightness, well, you're about a three-watt. But this guy. He's a wet match in a dark cave. He makes phone operators seem smart. [clears his throat] But more importantly, son, he's shown me what a sharp, quick-witted boy you've become. [hugs him] Ha! I feel like I'm really meeting you for the first time. Isn't that right, Janet?

Janet: You bet, Marty.

Patrick: [his eyes widen and is now in shock] Janet?! Marty?! Who are you people?!

Janet: Marty, I'm scared. [Doorbell rings, then the rock opens up. Squidward, Herb, and Margie are outside his rock]

Squidward: Excuse me. Does this lovely couple belong to you? They've been standing outside my house saying "Where's Patrick?" all day. It's driving me nuts!

Patrick: Mom! Dad! [hugs them]

Herb Star: Wow, son! You actually recognized us this time.

Margie Star: And you remembered to get dressed today. [Patrick, Herb, and Margie laugh]

Marty: Oh, that's right, honey. We don't have a son.

Janet: Oh, yeah. [both walk away. Patrick and his parents laugh as their rock closes over them, then the screen fades to black, ending the episode]
