I love watching the Comedy Central show called South Park.
Really! What channel do you watch it?
I don't have the Comedy Central channel anymore, so I have to watch it online. The show features four boys name Stan, Kyle, Eric, and Kenny. 
Tell me a little about the characters as mentioned
South Park uses a very large ensemble cast in its show, much like The Simpsons. But of the four boys, Eric Cartman is kind of overweight and whiney. Kenny McCormick always gets killed. Stan and Kyle are pretty normal and usually just along for the ride. 
Is it a Disney programme?
No, the content is more adult than most Disney, although it is animated. For instance, there is an episode titled "Cartman Gets an Ana.l Probe" that wouldn't be very Disney-like. It's actually the first episode.
