South Park is a show I watch at least once a day on tv.
I have heard of that show, seen it couple of times it revolves around four boys—Stan Marsh, Kyle Broflovski, Eric Cartman, and Kenny McCormick, its funny
Yeah it can be a bit mean and disgusting at times soon.
Yes, but in a fun way, it uses a very large ensemble cast of recurring characters same like the simpsons
Yes, that is nice to have the same characters return a lot. I think their focal was on Kenny a lot. 
Yes he is the main character i think, it debuted in 1997 consistently earning the highest ratings, still its really popular 
Yes I can't believe how popular it became. I think it is on the Adult Swim channel?
Yes now its on Adult Swim is the adult-oriented nighttime programming block, from cartoon network channel
