South Park on Scientology
Takes some balls to openly mock a group of crazies that loves nothing more than to file lawsuits against anybody that speaks truthfully about them. As they animated the Scientology beliefs complete with the alien named Xenu and the trapped souls on earth and the DC-8s flying through space they had the words "This is what Scientologists actually believe" plastered across the screen. Then at the end as Stan outs the group as frauds, they threaten to sue him and he taunts them with "Sue me! Sue me!". During the credits, everyone was listed as John Smith or Jane Smith. Did I forget to mention that they kept asking Tom Cruise and John Travolta to "come out of the closet"? Hilarious stuff.
I can almost guarantee that the show gets sued over this. Hell, I bet they want to. The publicity would be priceless. And then we could get to see even more of those nut jobs looking like fools.
