This isn't even something I put up. I found it, I'll even tell you how!
I went on you tube and typed in full episode south park and it was like the third, fourth, or fifth one down that said something like, "Here's how to DL every SP episode free!" So i clicked on it just to watch it, thought it would be bogus like anyone else. It basically just gives you the website and walks you through every step. I tried, VERY cautiously, and I clicked on a season, then an episode, and long behold, a full episode of SP from season 10! You can DL any episode that has ever been aired for free! It's nuts! There's no front page that asks for an email or CC #, it's legit free site. I can't believe it myself, but I'm watching my 6th episode of the night! It even has the last episode aired on WED!
Seriously, if you like SP, checl it out.
