Dude, what are we going to do this weekend?
Nothing's going on.
I don't know.
Dude, it's Benson!
Alright, so that's tonight. Don't forget it.
- We'll be there. - See you there.
- What was that all about? - I don't know.
Oh, Mordecai and Rigby. What costumes are you going to wear?
Costumes?
Muscle Man's throwing a birthday party for Hi Five Ghost.
Apparently it's a costume birthday party.
Let me see.
Ah, what? It's invite only.
You guys got invited, right?
We didn't even know there was a party.
- Did you know there was a party? - No, I did not.
We didn't even know there was a party.
Oh, well...
Maybe you weren't invited.
Hey, Muscle Man. We heard that you're having a party tonight.
What time should we show up?
NEVER, YOU'RE NOT INVITED!
Dude! What's his problem?
Why won't he invite us to his party?
Dude. I know why he's not inviting us to the party.
Why?
Remember when you were choking this morning.
Look at Rigby's face!
Oh no, he's choking! Don't worry, dude. I gotcha!
Aw, sick! Your chokewad spat soda in my face!
Dude, that wasn't our fault, I was gonna die!
And besides, we got him a new soda.
Ugh, quit whining!
Here's another soda, ya big baby!
Yep, that's probably why he's not inviting us to his party.
We gotta go apologize.
What?
Hey, Muscle Man. We're sorry about that soda thing this morning,
so we bought our console as a peace offering.
You can borrow it for your party.
One, I don't know what you're talking about and B, I'm busy.
But I'll still take your video game.
Yo Hi Five Ghost! I found a video game system on the ground.
Let's see what happens when we put it in the microwave.
Dude, you said that was gonna work.
I know, I know.
He'd better not trash our system. That thing wasn't cheap!
Come on!
Ugh! Man, he's not gonna invite us.
We already said sorry. What else can we do?
Oh, I know what to do.
What?
We just have to make Muscle Man think that we don't wanna go to his party.
- What? - Reverse psychology.
If he thinks we're not into it, then he'll really want us to be there.
Nice.
Just act like the party's lame and watch the invitations come rolling in.
Muscle Man, we don't wanna go to your party.
Good, because I wasn't gonna invite you anyway,
so get lost!
Muscle Man,
we're sorry about the soda!
What are you talking about? I said GET LOST!
Forget it!
Wanna play some video games?
We gave away our system, remember?
Well, whatever. The party's gonna be lame, anyway.
It's just gonna Pops, Skips, and Benson sitting around doin' nothing.
Dude, forget the invitation. Let's just crash it.
Yeah.
Dude, this is amazing.
Hold up! You're not on the list.
What? How do you know we're not on the list?
Name?
Mordecai and Rigby.
Not on the list!
I can only let people in that's on the list.
Yo, hold up! You're not on the list!
Ey, yo, Bobby! You can let that guy in.
He seems legit.
Let's keep this party goin'!
Right this way, sir.
Aw, what? He didn't even have a costume.
Yeah, what the H, Bobby?
Dude, let's go.
Wait, where you goin'?
We're gonna get into this lame party.
Dude, come on.
We'll just go through the window.
oo! Par-tay!
Hey, it's fives!
- Happy birthday, fives! - Whut?
Woah, sorry. We thought you were someone else.
Dude, I'm not Hi Five Ghost! I'm his brother, Lo-Five Ghost.
What're you guys doing out here?
The party's inside!
Haha, yeah... we... weren't really invited.
What? Why not?
That's what we wanna know.
We don't really care - we just wanna get in.
OK, look. I'm not supposed to say this but,
if you really wanna get into the party,
I can turn you into a ghost.
Really?
Yeah, then you won't have to go through the door!
You can go through the wall.
Plus, your costumes will be a lot more believable.
So, what do you say? You guys wanna do it?
- Let's do it! - OK, yeah!
Alright! Up high! Down low!
Now you're ghosts.
Aw, man! THis is so cool!
Dude, dude, punch me in the face!
OK!
I thought stuff's supposed to go through us.
Well, yeah, real stuff if you want,
but not other ghosts.
Party!
Mordecai and Rigby, hello!
Hey, happy birthday!
Yeah, happy birthday!
Thanks!
So, you guys got invited after all?
You could say that.
What wonderful costumes!
These aren't costumes.
Wait, those aren't costumes?
Yeah, no, we're totally ghosts!
Yeah, your brother turned us into ghosts
so we could sneak in here and wish you a happy birthday.
Oh no. This is bad.
Yeah, we're bad! We do whatever it takes to party!
No - you've got bigger problems.
If you don't get turned back into yourselves soon,
you'll be stuck as ghosts forever!
What? Well change us back!
I can't! I don't know how!
Dude! You turned them into ghosts?
Change them back!
I don't know how to!
But... maybe dad knows!
Not good. Not good at all.
If you want to turn back into yourselves,
you have to scare someone.
Scare someone?
Yes. It's the only way.
Dude, let's scare Muscle Man.
He doesn't know we're here yet so he won't be expecting it.
OK, let's do it!
Oh, man! I gotta use it!
He's going to the bathroom. Quick, hide!
What's he doing?
Oh no. He's having a heart attack!
We need a doctor!
Everyone back up, back up!
What happened?
We scared him... and he fell over!
OK, step back, let him breath.
He's not breathing!
he's gone.
You killed my best friend!
- We're sorry! - Yeah, we didn't mean it!
We just wanted to get into the party.
Got you, dudes!
Best! Prank! Ever!
What? What's wrong with you?
This was a prank?
Yeah, it was! And you two fell for it!
Wait. I thought you invited us to a costume party.
I did.
But that was just the beginning of my plan.
When you jerks spilled soda in my face,
I knew I had to get you back.
That's when I decided to throw a party.
I invited people and I made sure that you were aware of that.
Then we bailed Fives' brother out of jail
so he could turn you into ghosts.
It was the ultimate prank.
The ultimate payback.
Wait... but if you wanted to prank us at the party,
how come you didn't invite us?
Easy,
not inviting you was the only way I knew you'd show.
It's called reverse psy-cho-logy, babies!
This is the lamest and most expensive prank ever.
And it was worth it.
Maybe next time you'll think twice before spilling soda in my face.
Yeah, we'll definitely think twice.
Alright, I'm out of here.
Where you guys goin'? Thee's still plenty of food!
Oh, dude, Muscle Man's choking!
You have to help him! You're a doctor!
No, I'm not a doctor!
That was just part of the prank! Does anyone know the Heimlich?
Mordecai knows it!
Yeah right, he's just faking it.
As soon as I help him hes' going to be all.
Got you again, dudes!
I'm sick of it.
Ah, lame. Dude, are you pranking us?
Dude, he's not pranking us!
I got you Muscle Man, I got ya!
I hope this makes us even.
It does.
Lo-Fives, change 'em back.
I'm sorry I pranked you guys so hard.
Look. It's gonna be a real party,
and you guys can stay if you want to.
So, seriously. Is this a real party or not?
Does this answer your question?
No. Doesn't really answer my question.
I thought I could get it in the tape deck.
Here. Does this answer your question?
Everybody party!
Can you believe this?
No.
Hey, next time you see Muscle Man with a soda,
can you remind me not' to spill it in his face?
Yes. Yes I can.
Hey guys. I thought you'd like to have this back.
Aw, thanks!
Hey, wait. Is this just paper mache?
Yeah, sorry guys.
I sold the real one to a pawn shop. It was all a part of the prank.
Are you serious?
What's wrong with you?
Got you, dudes!
