Freedom isn't free! It costs folks like you and me...
Really, the entire soundtrack, from the hilarious vocal themes that are all dead-on satires of Hollywood cliches, to the surprisingly kickass soundtrack by Harry Gregson Williams.
The Dicks, Pussies, and Assholes speech.
Gary Johnston: We're dicks! We're reckless, arrogant, stupid dicks. And the Film Actors Guild are pussies. And Kim Jong Il is an asshole. Pussies don't like dicks, because pussies get fucked by dicks. But dicks also fuck assholes: assholes that just want to shit on everything. Pussies may think they can deal with assholes their way. But the only thing that can fuck an asshole is a dick, with some balls. The problem with dicks is: they fuck too much or fuck when it isn't appropriate — and it takes a pussy to show them that. But sometimes, pussies can be so full of shit that they become assholes themselves... because pussies are an inch and half away from assholes. I don't know much about this crazy, crazy world, but I do know this: If you don't let us fuck this asshole, we're going to have our dicks and pussies all covered in shit!
The original explanation is one for Parker and Stone. Given how long it goes on it could have easily lapsed into Metaphorgotten (and that probably would have been a good joke in its own right), but instead the whole thing makes perfect sense.
