Gets a cool from me.
Southpark was really a bit of a taboo here when it came out. It took a while for people to look past a lot of the jokes that seemed to be in horribly bad taste, but mixing that sort of in-your-face humour with some criticism towards society (in some episodes, at least), gives Southpark some merit, as far as I am concerned. Not getting strange looks for liking the show is also a slight bonus, in terms of coolness.
Sub Zero, however, is reserved for the shows that really coined my childhood, like The A-Team...
