Let's do it.
Hey, muscle man, we heard you're having a party tonight.
I gotcha, Muscleman!
We don't really care.
Dude, are you pranking us?
Look at Rigby's face.
What?
So, you guys got invited after all.
You didn't even have a costume.
We just want to get in.
You guys want to do it?
All right.
You can go through the wall.
Muscle Man, we don't want to go to your party.
Hey, guys.
Mordecai and Rigby!
Wait, those aren't costumes? Wait, those aren't costumes?
Not good at all.
I thought you'd like to have this back.
Ugh, forget it.
I'm sick of it.
Dude, that wasn't our fault.
