Rick and Morty in “Unfinished Business”

Hey, Morty, lemme-- [burps] lemme-- [burps again] lemme ask you a question real quick: does evil exist, and if so, can one detect and measure it?

Um...

Rhetorical question, Morty. The answer is yes, you just have to be a genius. [scans the microscope from Mr. Needful; an "IQ" bar on the laptop drops to nearly 0] Cute. Your sister’s boss gave me a microscope that would have made me retarded.

Ooh! Oh boy, Rick. I don’t think you’re allowed to say that word, you know?

Uh, Morty, I’m not disparaging the differently-abled. I’m stating the fact that if I had used this microscope, it would have made me mentally retarded.

Okay, yeah, but I don’t think it's about logic, Rick. I-I think the word has just become a symbolic issue for powerful groups that feel like they're doing the right thing.

Well, that's retarded.
