Butters said he got a letter from his Essay over at the docks. After Cartman told the mexicans to write essays. So maybe Butters is secretly a little bit Mexican
(like in a future episode of Family Guy, that Peter learns hes an mexican imigrant)
I thought it was funny how it seemed like they were cracking on Mexicans at the begining of the episode, then at the end, they put them in a good light, by saying the kids are actually learning something from them. "you've got to find the lowest common denominator"
Also there's strange rumors going around that after this Limus BS that they(don't know who they is) want South Park toned down.
I find it very hard to believe that this will happen...EVER!
Comedy Central owns South Park so they can't take it anywhere else.
I'm sure Comedy Central would love some controversy (for being over the top like Garrison 'scissoring' on camera- not Imus style stupid comments) because it generates free publicity so toning down the off wall stuff is probably not what they're interested in.
