Cartman: Well, I'm out guys. If this is what's cool now, I think I'm done. I no longer have any connection to this world. I'm gonna go home and kill myself. Goodbye, friends.

Kyle: What happened? I thought you were gonna kill yourself.
Cartman: I tried. Went to sleep in my mom's car in the garage with the engine turned on.
Stan: But you didn't die?
Cartman: Freakin' hybrids, man. They just don't do the job anymore.

Male CPS Agent: We're from Child Protective Services. There's some concern you might be physically abusing your child.
Mr. Güermo: What? Who the hell's been saying that?!
Female CPS Agent: We got a phone call from a concerned student who wishes to remain anonymous.
Male CPS Agent: His name is Stan Marsh.

Stan: Look, guys. The world is changing. We can't fight it, we have to change with it. I've been watching these movies, and from the looks of it there's gonna be a lot more singing and dancing when we get to high school. And if you think we'll gain respect by ignoring this thing and being individuals, then think about this: right now, everyone thinks Butters is way cooler than any of you.
Cartman: That's a low blow, Stan.

During the basketball game against the Westchester Bobcats, the score reads Home: 10, Visitors: 12. After Bridon makes the 3-point shot, the score doesn't change.

High School Musical:

The entire episode is a spoof of High School Musical (2006) and its sequels. The songs, characters, and conflicts from the episode are borrowed from the films. For example, Bridon's personality and appearance is modeled after Troy Bolton, played by Zac Efron. The only difference between the two is Bridon wants to play basketball, as opposed to Troy wanting to sing. Another reference to the films would be Kyle's hair in the final singing number. It is identical to Chad Danforth's, played by Corbin Bleu.

Rolling Stones:

During the final dance number, Kenny can be seen wearing a shirt with the famous tongue logo, used by the Rolling Stones. Created in 1970 by John Pasche, the logo would be used on numerous Stones album covers and has now become a symbol of the band. The original design was purchased by the Victoria and Albert Museum on September 2nd, 2008.

Bye Bye Birdie:

During one of the scenes at Bridon's house, his father, Mr. Güermo, sings the line "what's the matter with kids these days!" This is a reference to the song "Kids," in the film Bye Bye Birdie (1963).

Jimmy: Where the hell have you guys been?
Craig: Peru.

Craig is referring to the previous episodes "Pandemic" and "Pandemic 2: The Startling," where the boys, along with Craig, were sent to Peru after becoming a pan flute band.
