Continuity mistake: In the beginning, throughout the breakfast scene, items on the table change. For example, the cereal box position and at one point Morty puts his fork down next to his plate by the edge of the table, but in some shots it's not there.
Continuity mistake: When Summer is surrounded by the army and talking to the car, we see her seat has stuffing coming out of it on two spots. But shots facing her, you can see there's no stuffing coming out of her seat and it's the driver's seat that has the stuffing sticking out.
Trivia: The show originated as a 2006 short parody of the film series "Back to the Future", entitled "The Real Animated Adventures of Doc and Mharti." Eventually, creators Justin Roiland and Dan Harmon reworked the concept into the series that would become "Rick and Morty" during the brief time that Harmon was fired from his other series "Community" during the fourth season. When Harmon was rehired for the fifth and sixth seasons of that show, he simultaneously worked on both series at the same time.
Rick: Cute, your sister's boss gave me a microscope that would have made me retarded.
Morty: Ooh. Oh, boy, Rick, I, I don't think you're allowed to say that word, you know.
Rick: Morty, I'm not disparaging the differently abled. I'm stating the fact if I had used this microscope, it would have made me mentally retarded.
Morty: 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.
Rick: Well, that's retarded.
Old Alien in Wheelchair: I've dwelt among the humans. Their entire culture is built around their penises. It's funny to say they're small. It's funny to say they're big. I've been at parties where humans have held bottles, pencils, thermoses, in front of themselves and called out, "Hey, look at me. I'm Mr. So-and-so dick. I've got such-and-such for a penis." I never saw it fail to get a laugh.
Jerry: With all due respect, Rick. What am I talking about? What respect is due? How is my son suppose to pass his classes if you keep dragging him off for a high-concept sci-fi rigmarole?
Rick: Listen, Jerry, I, I, I don't wanna overstep my bounds or anything. It's your house. It's your world. You're a real Julius Caesar. But I'll tell you something, I tell you how, how I feel about school, Jerry. It's a waste of time. A bunch of people running around, bumping into each other. Guy, guy up front says two plus two, the people in the back say four. Then, then the bell rings and they give you a carton of milk and a piece of paper that says you can go take a dump or something. It's, it's not a place for smart people, Jerry. I know that's not a popular opinion, but it's my two cents on the issue.
Question: On the IMDB, the credits for each episode in season 1 (except for episode 8) list "Unity" as playing "Themselves" or "Themself", sometimes listed as uncredited and some times not. However I never saw Unity listed in any credits on the show itself. (It should be noted, I'm not talking about the character Unity from season 2 which was voiced by Christina Hendricks). Looking further on IMDB, Unity has appeared on a dance show where it appears Unity is a dance crew and not an individual with a weird name. So who is Unity playing in a cartoon if they're just dancers and not voice actors? Did the dance crew actually do any voice work or help with any dance scenes, even though they're just drawings and not motion captured?Bishop73
