Definitely not politically correct stuff, but the new season of South Park has started with, well, an explosion, a flood, global warming and much, much more.
Trey Parker, Matt Stone and the rest of the folks behind South Park went above and beyond with the newest episode, the season premiere, that aired originally on 10/19/05: "Two Days before the Day After Tomorrow"
Just going on memory, but lets say that they were poking fun of FEMA, disaster responses in general, finger pointers that would place blame for natural disasters, Spartacus, people that build homes below the flood plane, and so much more. Hard to believe that they made it all fit in the approximately 20 minutes worth of actual show that was aired between several minutes of commercials.
It had been a long wait since the last season aired (or at least it felt that way), but the wait seems to have been worth it. Not politically correct by far, but most definitely hilarious stuff.
If you missed the original airing, but get Comedy Central, then be sure to catch one of the repeat airings, and be prepared to laugh long and loud.
