Rick, Villager and others in “Unfinished Business”

Hey, Muchacho, does your planet have wiper fluid yet or you gonna freak out and start worshipping us?

The general store ought to have what you need.

Thanks.

Of course, you'll be wanting to be gone from here by sundown.

Yeah, sure thing. Wait a minute, what? Why?

Sundown is when the Festival begins.

The Festival?

Ooh, well, for millennia, our society has been free of crime and war, livin' in perfect peace.

Oh! I know what this is! You've been able to sustain world peace because you have one night a year, where you all run around robbing and murdering each other without consequence!

That's right!

What?!

It's like The Purge, Morty! Th-That movie, The Purge?

Oh, have you been here before?

No, no, but I've been to a few planets with the same gimmick. Y'know, sometimes it's called the Cleansing or the Red Time. There was this one world that called it just Murder Night. I-It's a purge planet. They're peaceful and then, y'know, they just purge.

Th-That's horrible!

Yeah. [beat] You wanna check it out?
