Nathan and Garth are cleaning out the gutters of the house. Nathan picks up the dirty leaves and puts them into a bucket.

Nathan: Augh! This is the worst.

Garth: I don't know, I kind of like it up here. The world seems different at this height. It makes me feel like a giant! (Roars)

Nathan: What? Look, we're not up here to enjoy the view, so will you just come and help me clean these gutters?

Garth: I'm helping, I'm holding the hose. Look, I'm taking a giant leak. (Positions the hose to his crotch, turns it on, and pretends to pee) Ohhhhh.

Nathan: Yeah, well, you don't need those gloves to hold the hose. (holds up hands) Look at this dude. Come on, let me wear them!

Garth: Sorry Nathan, you should have thought about that before you threw paper, and lost to my scissors.

Nathan: Augh! Whatever, dude. Just hose this stuff off.

Garth hoses the leaves out of the gutter. A cassette tape is launched into the air.

Nathan: Whoa! (Caught the tape before it hit his head) What the heck?!

Garth: Uh, sorry.

Nathan: Weird, it's a tape. Wonder what it's doing up in the gutter.

Garth: [looks up at the sky] Maybe it fell out of a plane.

Nathan: Nah, it's probably just trash. I wanna see how far I can chuck it.

Garth: Wait!

Nathan: What?

Garth: Don't you wanna see what band it is?

Nathan: Oh, okay. (wipes dirt off of tape to reveal the words "Solid Bold") Solid Bold? Augh, it's that single of that summertime song.

Garth: "Summertime Loving: Loving in the Summer (Time)"?

Nathan looks at the tape. It says exactly what Garth said.

Nathan: Yeah.

Garth: Gimme! Gimme! Gimme! (grabs tape) Aw, this is my jam right here!

Nathan: (annoyed) What? This song sucks.

Garth: Nah, you were all into it too, I remember.

Nathan: Yeah, just for that one summer, and then I realized how lame it was.

Garth: Whatever, man. Once we pop this into the stereo, all the good memories will come flooding back, and you'll see. You'll see whose jam it is.

Nathan: (annoyed) I'm not listening to that trash.

Garth: You need to get your mind out of these gutters, and into the summer.

Nathan: Fine, but only because I want to take a break.

In Nathan's room, Garth puts the tape in the stereo. The song starts

Singer: It's summertime, and you know what that means. Gonna head down to the beach, gonna do some beachy things. It's summertime and it feels just right.

Garth: Yea-uh![dancing to the music]

Singer: Gonna gather all my friends and we'll party through the night. It's summertime, lo-o-ovin'. Lovin' in the summertime. (It's summertime) Summertime lo-o-ovin'. Baby, why can't you be mine?

Garth: [uninterested] Okay, this song's lame.

Nathan: (uninterested) I told you, man.

Singer: Summertime...

Garth ejects the tape and throws the tape into the garbage.

Garth: Man, I guess some stuff just doesn't hold on.

Nathan: Now you're making sense, and now I'm making snacks.

In the kitchen, Nathan and Garth are eating grilled cheese sandwiches.

Garth: [singing] It's summertime... (eats sandwich) Lo-o-ovin'... (eats again) Loving in the summertime.

Nathan: (confused) What are you doing?

Garth: (oblivious)What?

Nathan: You're singing that song.

Garth: (surprised) I am?

Nathan: (now annoyed) Yes, please stop. It's annoying.

Garth: I guess it's pretty catchy.

Garth confusedly eats his sandwich. Back on the roof, Nathan and Garth cleaning the gutters.

Garth: [singing] Summertime lo-o-ovin'. Baby, why can't you be my-

Nathan: Garth!

In the living room, Nathan and Garth watching television. Garth still singing.

Garth: [singing] Gonna head down to the beach, gonna do some beachy things.

Nathan: Garth!

Cut to Nathan and Garth walking in the park, Garth sings again, however, Nathan is annoyed by this song, unable to take it anymore.

Garth: [singing] It's summertime lo-o-o-

Nathan: (blows up in annoyance) Dude! Shut up!

Garth: I'm sorry, I can't help it, it's stuck in my head, and I can't get it out.

Nathan: Well, for my sanity and yours, we gotta get that song outta there.

Garth: Yeah, okay.

Back in Nathan's room...

Nathan: Okay, okay. I've got the perfect solution: 80's music's.

Garth: That would work.

Nathan: And what better way to do that, is Michael Jackson's music. (puts CD in stereo)

CD plays 'Wanna Be Starting Something?' By Michael Jackson

Nathan: [humming] Aw man, it's a classic. [glares at Garth sleeping] Garth!

Garth: [startles] Lovin' in the summertime. What? Ah, I think your song just put me to sleep.

Nathan: [turns stereo off] Man, you have no taste in music.

Garth: Look, all I know is that this song is still stuck in my head.

Nathan: Alright, well, what if we sit down and listen to the entire summertime song from beginning to end? [retrieves summertime cassette from trash] That way your brain has closure and then it can move on. [puts cassette into stereo]

Singer: It's summertime and you know what that means. Gonna head down to the beach, gonna do some beachy things.

Nathan: [walks out of the room] I can't stand this, I'm gonna wait outside.

Singer: It's summertime and it feels just right. gonna gather all my friends and we'll party through the night...

Timeskip where Garth is sitting on the bed, the 1song is still playing.

Singer: Summertime lo-o-ovin'. Baby, why can't you be mine?

Timeskip where Garth is lying against the nightstand, the song is still playing.

Singer: Summertime lo-o-ovin'. Lovin' in the summertime.

Garth turns the tape off, and Nathan opens the door.

Nathan: Well, did it work?

Garth: (in the tune of the song) I think it worked, but I can't be sure. So maybe I should listen to the song a little bit more.

Nathan: Aw, man! It's even worse now. Time to take a different approach.

A montage of Nathan and Gartj doing various things to get the song unstuck, like sticking Garth's head in a toilet, using loud objects, and finally Kara hitting Garth on the head with a broom. Garth starts taking his helmet off.

Garth: Wait. Stop. Stop. It's not working. The stupid song's still stuck in my head.

Kara: You have a song stuck in your head?

Garth throws a helmet at Kara, much to her annoyance. Nathan and Garth are back in the bedroom.

Nathan: Man, we're running out of options here. Let's see.

The song starts playing.

Nathan: Dude, turn it off, I'm trying to think. Garth, stop playing the tape we've already tried- [turns and gasps] Whoa!

Garth is floating with a purple beam with white scribbles and small neon green stars coming out of his mouth and pupils dilated.

He suddenly goes back to normal and the song stops playing.

Nathan: Dude, what's wrong with you?!

Garth: I don't… [floats again, goes back to normal each time] …know! I can't… control it! [floats again]

Nathan: We gotta find John.

Nathan and Garth in John's house

John: Yeah, I've seen this before. Hold still. [holds floating Garth and punches him]

Garth: Oww! What was that for?!

John: You're not thinking about the song anymore, are you, mate?

John and Nathan laugh.

Garth: It's not funny- [floats again, goes back to normal] -see and it didn't even work.

John: Look, seriously, I don't know what's wrong with you. Just sleep it off, you'll probably forget about it in the morning.

Cut to Garth's house, where Garth is sleeping. The background is empty.

Garth: Hello? [walks]

A large speaker emerges from the ground playing the song. Garth runs and another speaker emerges.

Garth: Get out, get out, get out, get out, get out! [screams]

Garth digs into his ear, pulls out the cassette, and throws it far away. He laughs victoriously but suddenly, a giant shadow emerges and runs towards the Atlantean. Garth wakes up.

Garth: The song. It's gone!

Garth got up and ran to Nathan's house.

Garth: [knocks on his door] Nathan! Nathan!

Nathan: [opens the door] What's up?

Garth: The song's not in my head anymore!

Nathan: That's awesome, dude. Now we never have to hear that dumb song again.

Suddenly, they hear the song again.

Nathan gasps, prompting Garth to turn around. To their horror, they realize that the situation has gone much worse than they thought. Although Garth was able to get the tape out of his head, now with the cassette free, it manifests itself in physical form. Now he's a large cassette with stick arms and legs and red sunglasses.

Nathan: What the hell is that?

The giant cassette continues to play.

Garth: I have no idea what I'm looking at.

Nathan: I think the song must've left your head and manifested itself into a physical form.

Garth: Well, does it have an "Off" switch?

Nathan: I don't know.

Garth: Hey, dancing song guy! Knock it off! Come on, quit it! Seriously, I'm sick of this song!

The cassette drums on Garth's head.

Garth: Get off! [tackles cassette and goes right through it] Oh my gosh, it's a ghost tape!

Nathan: Dude. Calm down. It's not a ghost. It's just music. You can't touch music. But music can touch you.

Garth: How do we get rid of it?

Mordecai: I don't know. If we just ignore it, it'll probably just go away.

A montage of the heroes doing everyday normal activities with the cassette dancing around them.

Everyone, especially Diana, gets annoyed, Diana leaves in annoyance as the others walk away extremely irritated.

At Metropolis High. Unable to stand any more of this song, the duo is seen going into a room and locking it.

Nathan:  Dude that's it, we gotta do something about this.

Garth: What can we do? He's unstoppable!

Nathan: We gotta fight fire with fire.

Garth: But the fire's just gonna go right through him.

Nathan: No dude, we gotta battle him with our song.

Garth: What?

Nathan: We're gonna write the cheesiest, most repetitive, catchiest song ever, and we'll see how he likes it.

Garth: Aw, snap!

Nathan: And that's the perfect title!

The cassette comes running down the hall and then walks through the wall.

Nathan: Come on!

Nathan and Garth exit. They run into Babs.

Nathan and Garth: Babs!

Nathan: We need you to distract the "Summertime" Song.

Babs: But I can't stand that song.

Nathan: I know. We're gonna get rid of it for good. But we need you to buy us some time, so just go dance with him and pretend like you're having fun.

Babs: Alright, then.

Nathan: Thanks, Babs.

Nathan and Garth run away

Babs: You owe a burrito for this!

The cassette comes up to Babs. Nathan and Garth open the door of the music class and walk up to the keyboard.

Nathan: Okay, song, song... [plays some notes] Okay, we'll just repeat that. And lyrics, go.

Garth: Uh, Summertime loving.

Nathan: No, Garth, come on. Give me something I can use. What do you like?

Garth: Partying.

Nathan: Yeah, uh huh. Uh-huh.

Garth: Macaroni. Oh, naps! I love naps.

Nathan: Alright, good enough.

John: Okay, I'm here. And I brought my violin.

Carter: I brought my bass

Nathan: Wait. How did you...

John: I know everything, remember?

Nathan and Garth: [amazed] Whoa...

John: Nah, I'm just yanking you, mate. Carter and I were on the cans and we heard your plan.

Carter: Yep, it's true.

Nathan and Garth: [disgusted] Ugh!

John: I already told the others about your plan.

Carter: Let's roll.

Back to Pops and the cassette.

Mordecai: (on the phone) Babs.

Babs: Yes, hello?

Nathan: I need you to lure the "summertime" song outside, okay?

Babs: Yes, okay. [to the cassette] The party continues this way.

Babs and the cassette run down the stairs. At the football field, the heroes set up their gear.

Nathan: Okay, get ready guys.

Cisco: Stereo is good.[on bongos]

Kara: [on electric guitars with Dick and Jason] Guitars ready.

Hal: [on bass guitar with Barry and Virgil] Bass ready.

Oliver: [on the acoustic guitar] I'm ready.

Jessica: [on cello guitar with Zee and Diana] We're ready.

Stephanie: [on the keyboard] I'm ready.

Nathan: Where's Tim?

Dick: He's working on his drum kit. But he's almost done.

Nathan: Let's hope he gets here.

Garth: Here they come![They see Babs luring the cassette outside]

Nathan: Babs!

Babs runs to the other keyboard next to Stephanie.

Garth: [tapping tambourine] One, two, three, four!

Young Justice: [sings] Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap. Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap. Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap...

The cassette hits back with sound waves by playing the song. The waves drown them out]

Nathan: Louder! Come on!

Young Justice: [sings] Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap. Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap.

Their sound waves knock the cassette over. The cassette shoots a purple beam and they shoot out a green one. Two giant musicians appear in the sky and fight.

The combined sound waves knock down the Metropolis and shatter the windows of the mansion where Dick, Jason, and Tim live. Tim looks out his window and runs out the door. The cassette's giant musician overpowers their giant musician.

Hal: He's too strong!

Nathan: No, we can do it!

The Young Justice are being overwhelmed by the cassette music. They all collapse and see Tim driving the car toward them.

Tim: Sorry, I'm late guys!

Nathan: Is it done yet?

Tim: You know it.[reveals a drum set] Let's finish this.[begins drumming impressively]

Tim taps his drumsticks and they resume playing.

Young Justice: [sings] Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap.

Their giant musician begins overpowering the cassette's giant musician.

Young Justice: [sings] Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap. Aw, snap!

Their giant musician smashes the cassette's giant musician, and the cassette explodes. The heroes cheer for victory.

Nathan: Alright! We did it!

Tim: I'm glad that we won't have to listen to that dumb-.

Garth: [pupils dilated] Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap. Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap.

Everyone except Garth: (much to their dismay and horror) Nooo!

The End
