All the South Park episodes have been put online for free (legally):

They're doing it the same way as NBC did it, with one commercial on each break, and the quality is good (for a streamed video). It's still in BETA stages, but everything seems to work.

Enjoy!

Woah. They've got every episode up to the new one this season, uncensored. Awesome.

Awesome link indeed!
