The last few seasons of South Park have taken a dip in quality, but it's still one of the better programs on television. And they had a run from about season six to twelve or so where literally almost every episode is tremendous. Rivals the Simpsons at it's best and eclipses most other television.

I will still always love the show unconditionally for episodes like
Best Friends Forever,
Cartoon Wars and
With Apologies to Jesse Jackson. No other show has ever reached the potent, hilarious cocktail of social satire those episodes are able to reach so effortlessly.
