Tasty Mystery Baskets of Clips

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