I love Family Guy, especially when I get to see in the original version, not the spanish one
. I like to hear original voices.
American Dad...Dont really like it... though I have seen just 3 or 4 episodes.
And about south park, I guess thats the most "politically incorrect" that you can get. Weird and funny at the same time. In fact its great, though I dont usually have the chance to see this one in OV, I have to listen to crappy spanish translations.
An they're a great way to know trivial things about American culture (more or less).
