Craig gives the right answer when asked where the boys were (Peru). :D
The events at the end of "The List" have had no lasting effects on Wendy or Bebe - they're friends again.
Wendy calls Bertha/Rebecca "Red" again.
Bridon is modeled after Troy Bolton (Zac Efron), but here he's a song-and-dance kid wanting to be an athlete.
"Go with the Status Quo" is a parody of Stick to the Status Quo. In reruns, the music that follows Cartman's departure is instrumental, not a repeated section.
The song the boys find the school singing when they arrive is a parody of We're All In This Together
Mr. Güermo is watching the same scene the boys watched earlier, but there's no audio. In repeats, the audio is there.
What's the matter with kids these days? - The last line of "Kids," from the 1963 movie Bye Bye Birdie
Bridon's dad slapped his neighbor's face from two doors down, then was suddenly back at his own doorstep. This is called the magical ninja slap.
"What are you doing?? Everyone's crazy!" is not in the first airing.
When the boys find Stan watching High School Musical 2, the first airing has a variation of "Go with the Status Quo" playing in the background. Later airings have an instrumental there.
The score doesn't change when Bridon makes the 3-pointer. The score remains Visitors 12, Home 10.
The girl with the gray headband returns, but she's still nameless.
Stan doesn't throw up on Wendy when she gives him a kiss on the cheek. Probably 'cause she told him she couldn't hope to be Bridon's girl rather than that she preferred him to Bridon.
