Believe it or not, South Park has shown some way crazier shit than that. Drinking cum, eating chili made out of people, and Gang Banging(sex). South Park always crosses the line and that's why I love it.
Yeah it's just really out there, I love stuff like that XD. Family Guy and Boondocks are also good shows too that aren't afraid to push it, plus Huey is awesome
Saddest thing is the fact that the creator left during the final season, it will definitely be a missed show, definitely one of a kind. My favorite episode will forever be the chicken one XD
