Favourite South Park episode?

I have so many favorites but "Imagination Land" episodes is on the list of ones I can re-watch but my favorite out of all is "Make Love Not Warcraft" episode. The movie is another thing I can re-watch many times but of course its not a episode so I cant put it in the list of favorite episodes but its still funny to watch. But I love Trey Parker and Matt Stone in the movie "BASEketball" as well. It is a great movie if you love "South Park" comedy. So you might like the movie you might hate it, just giving a good movie choice in my opinion.
