Drove me around the bend. It states clearly in the DSM that under 10% of those with Tourettes exhibit coprolalia. Yet the first thing they go to is that.

Well,
South Park will do anything to allow characters to swear.

And of course it makes sense that the reason Cartman would fake Tourette's is so he could get away with saying all those offensive things. They did address the other types of Tourette's later in the episode.
As for an AS episode - if the show stays on for a couple more years, I could definitely see it. AS continues to gain more publicity. There's already a phenomenon of people accusing others of faking AS. And this whole "Ransom Notes" debacle has resulted in the development of a political slant.
