In this episode, we learn that Kyle has a cousin from New York, who is also named Kyle, and is Jewish. Kyle Broflovski is referred to as "Kyle 2," because he and his cousin have the same name, and Sheila didn't want to call them both the same thing.

Mr. Garrison reveals claims that he earned a master's degree in mechanical engineering at Denver Community College.

Kyle 2: That kid over there is my cousin from the East Coast. He's having a really hard time right now, so I'm going to offer you forty dollars to not rip on him.
Cartman: Forty bucks?
Kyle 2: But you can't make fun of him AT ALL! No smartass comments, nothin'.
Cartman: All right, all right.
Kyle 2: And you especially can't say anything about Jews!
Cartman: Aw, Jesus, why don't you just cut off my balls?

Ms. Choksondik: Now Kyle, I need you to be quiet. In my class you need to be able to concentrate.
Cartman: Oh!
Ms. Choksondik: Concentration is the key to succeeding in my class.
Cartman: Maybe we'll have to send him to concentration camp. AGH! Dammit, dammit, dammit!!!
Kyle 2: CARTMAN!

Randy: Well, it seems all the buttons on these front and rear flexigrips are also found on the side of the vehicle.
Mr. Garrison: Yup.
Randy: Well... so... they don't really... do anything.
Mr. Garrison: Right.
Randy: So then, couldn't I just order one that works without going in and out of my ass and mouth?
Mr. Garrison: (thinks) Well, I... guess you could.

Mr. Hat: Boy, that Enrique Iglesias can sure gyrate his hot ass around.
