South Park.

...Vernacular, slang, accent, regional pronunciation of the english language. Kind of like Jesse Helms saying ponagapha, George Bush saying nucular, me saying yer, fer, stya, chya, mostly no spell check or a dictionary or thesaurus at hand. Above all it’s fun to mock people to cover up your own stupidity, and I got plenty of stupid that leaks out of my brain on a daily basis...
