Question: In which part(s) of the movie is the Kill Bill music (battle without honour or humanity) played?
Answer: Without giving a timecode, I can tell you that it's during the third act, when Team America has already been freed from their prison cells (in North Korea), and are fighting through the F.A.G. defenses.
Question: Does anyone know what the joke is about Matt Damon always calling out his name? Is it supposed to be a reference to something?
Answer: I read an interview with Trey Parker and Matt Stone where they said that they had not intended for it to be that way but that when they made the Matt Damon puppet, it looked so retarded that they thought it would be funny to just have him be retarded in the movie and only say his name. They said it was nothing personal against Matt Damon.
Question: What political party do Matt and Trey affiliate themselves with, and is it known who they supported in the '04 election?
Answer: When asked about what group they associated themselves with they replied, "I think we're like most people, just down the middle with our personal political affiliation". As for the '04 election I don't believe they supported either publically.
Question: I know that the musical being called 'Lease' is a reference to 'Rent', but what's the joke behind the song being called 'Everyone has AIDS'?
Answer: The musical "Rent" is based on the opera "La Boheme" in which the main character Mimi dies of consumption (tuberculosis). In the updated story for "Rent", the disease is AIDS rather than TB. Several characters in Rent have AIDS or are HIV positive.
