The answer: South Park.
Tonight's episode WAS a disappointment for me (Bush actually supporting the first amendment is the kind of political fantasy Trey and Matt have become famous for these last couple of years) but after reading Style's review I think I'll give it a rewatch. I liked the Bart Simpson kid and that Family Guy writers are all manatees but I think I was a little disappointed that the episode focused more on freedom of speech (which is an obvious message) and less on Family Guy sucking (which I suppose they covered last week). But as Style noted it was probably best that they did that since the free speech message is more important. Besides you can't unring a bell even if tonight didn't help their case against Family Guy.
