Something Ricked This Way Comes - S1-E9
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.
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.
Answer: C-137 is the dimension they came from since the pilot. After C-137 is Chronenberg'd, Rick and Morty travel to a replacement dimension that we haven't found out the designation of (although they may have moved dimensions again). The "original" Jerry, Beth, and Summer are still on C-137 though.
