Everything I Know I Learned From South Park

From Season Three's "Rainforest Schmainforest" :

(While driving through San Jose, Costa Rica)

Cartman: Oh my God, it smells like ass out here.

Miss Stevens (played by Jennifer Aniston): Alright, that does it. Eric Cartman, you respect other cultures this instant.

Cartman: I wasn't saying anything about their culture, I was just saying their city smells like ass.

Miss Stevens: You may think that making fun of third-world countries is funny but let me...

Cartman: I don't think it's funny. This place is overcrowded, smelly and poor. That's not funny, that sucks.
